What is the difference between width and precision in Python string format in case of strings -

What is the difference between width and precision in Python string format in case of strings -

what difference between width , precision in python string format in case of strings?

i mean smth this

'%5.5s'

precision interpreted maximum length, width minimum length:

>>> '%5.5s' % 'foobar' 'fooba' >>> '%5.3s' % 'foobar' ' foo' >>> '%3.5s' % 'foobar' 'fooba'

foobar truncated fit in 5 , 3 character maximum length, respectively. truncated string fit 5 , 3 character wide column (which can overflow).

twitter bootstrap - Rails 4 - Flash as Key Value Pair Error -

i trying utilize bootstrap styles display flash messages color users.

controller

def create @category = category.new(category_params) # assigning default values @category.status = 1.to_i if @category.save redirect_to admin_categories_path, :flash => { :success => "category created." } else flash[:error] = "category not save. please seek again." render :new end end

view

<%= render 'admin/partials/flash_message' %>

partial

<% if flash.present? %> <%= flash.inspect %> <% flash.each |key, value| %> <div class="<%= flash_class(key) %> fade in widget-inner"> <button type="button" class="close" data-dismiss="alert">×</button> <%= value %> </div> <% end %> <% end %>

helper

# flash messages def flash_class(level) case level when :notice "alert alert-info" when :success "alert alert-success" when :error "alert alert-error" when :alert "alert alert-error" end end output

i not able pass key helper function. assuming sends blank. html gets outputted

<div class=" fade in widget-inner"> <button data-dismiss="alert" class="close" type="button">×</button> category not save. please seek again. </div>

i not able figure out why foreach not able extract key , value pair. on inspect following

#<actiondispatch::flash::flashhash:0x007fc0e74dfa58 @discard=#<set: {}>, @flashes={"error"=>"category not save. please seek again."}, @now=nil>

in rails 4, supports strings. had alter helper following

# flash messages def flash_class(level) case level when 'notice' "alert alert-info" when 'success' "alert alert-success" when 'error' "alert alert-danger" when 'alert' "alert alert-warning" end end

**edit: according deep suggestions **

by changing flash partial to

<% if flash.present? %> <% flash.each |key, value| %> <div class="alert alert-<%= key %> fade in widget-inner"> <button type="button" class="close" data-dismiss="alert">×</button> <%= value %> </div> <% end %> <% end %>

and extendting bootstrap classes follows can eliminate helper class together.

alert-notice { @extend .alert-info; } alert-error { @extend .alert-danger; }

i trying have added 'li' tags animated upon entrance, preferably using css. adding transitions 'display', 'opacity', , 'all' have not resulted in change. here's code:

function additem(item){ item = document.getelementbyid('plan_submit').value; var listcontainer = document.getelementbyid('list_container'); listcontainer.innerhtml += '<li class=list_item>' + item + '</li>'; }

thanks :)

you can this:

function additem(text){ var item = document.createelement('li'); item.innerhtml = text; item.classname = 'list_item'; var listcontainer = document.getelementbyid('list_container'); listcontainer.appendchild(item); item.style.opacity = 0; settimeout(function(){ item.style.opacity = 1}, 1); }

css:

.list_item { transition:opacity 1s; }

it's of import utilize settimeout in case (even delay 1 ms). note utilize of class .list_item not necessary because can set transition newly added li using script.

ruby on rails - Topics have_many posts. Get all topics without any posts -

a blog has "topics", "topics" have "posts".

how can count of topics without posts? unused topics.

topics = topic.all topics.???

topic.includes(:posts).where('posts.topic_id null').references(:posts).count

after seeing other answers, ran both statements in console.

this reply generates next query

(0.9ms) select count(distinct "topics"."id") "topics" left outer bring together "posts" on "posts"."topic_id" = "topics"."id" (posts.topic_id null)

while other reply generates 2 queries (as obvious).

(0.6ms) select "posts"."topic_id" "posts" (0.5ms) select count(*) "topics" ("topics"."id" not in (2,3,11,23))

javascript - Defining global functions and properties accessible by AngularJS factory and controllers -

javascript - Defining global functions and properties accessible by AngularJS factory and controllers -

i'm working on angularjs app. when error thrown, want custom handling of error. that, i've done following:

var myapp = angular.module('myapp', []); myapp.factory('$exceptionhandler', function($rootscope) { homecoming function(exception, cause) { seek { console.log('unhandled error happening in version ' + $rootscope.app_version); console.log('error happened @ ' + $rootscope.getformatteddatetime()); } grab (uex1) { console.log('unable log unhandled exception.'); } }; }); myapp.run(function ($rootscope) { $rootscope.app_version = '1.0'; $rootscope.getformatteddatetime = function() { homecoming '--'; }; });

when run code, this error. guess can't add together $rootscope mill declarations. if that's case, how define globally accessible functions , variables can access them in controllers factory?

thank much assistance can provide.

you cant inject $routescope mill , , not thought however

the best can define new mill , , define property factoy :

app.factory('getappinfofactory',function(){ return{ getappversion:function(){ homecoming app_version = '1.0'; }, getformatteddatetime : function() { homecoming '--'; } });

and can utilize mill whenever/whereever want , :

myapp.factory('$exceptionhandler', function(getappinfofactory) { homecoming function(exception, cause) { seek { console.log('unhandled error happening in version ' + getappinfofactory.getappversion()); console.log('error happened @ ' + getappinfofactory.getappinfofactory()); } grab (uex1) { console.log('unable log unhandled exception.'); } }; });

so i'm wanting insert instance can see below. however, how alter code reject/exclude 'segment' , 'timezone' key above?

filters = $.extend({}, @metatagsadvanced)

any help appreciated allow me refactor of code! (i'm using coffeescript, hence why it's formatted way is!)

cheers

i'd utilize utility library lodash or underscore more robust solution, if didn't want rely on native prototype methods on array. intermittent log statements show how gets built up.

jsfiddle here: http://jsfiddle.net/trqg8/

jquery only sometags = foo: {foo: 'bar'} bar: {foo: 'bar'} baz: {foo: 'bar'} _keys = (obj)-> $.map(obj, (value, key)-> key) # seems odd key lastly appears way jquery 2.1.0 works. console.log _keys(sometags) # => ["foo", "bar", "baz"] _in = (arr, key)-> arr.indexof(key) != -1 console.log _in(_keys(sometags), 'foo') #=> true # there native filter function array.prototype _filter = (obj, keys...)-> objkeys = _keys(obj) # poor man's cut down ob = {} k in objkeys ob[k] = obj[k] unless _in(keys, k) ob console.log _filter(sometags, 'bar') #=> object {foo: object, baz: object} console.log $.extend({}, _filter(sometags, 'bar', 'baz')) #=> object {foo: object} underscore

in contrast, using underscore this:

sometags = foo: {foo: 'bar'} bar: {foo: 'bar'} baz: {foo: 'bar'} console.log _.extend({}, _.omit(sometags, 'bar'))

linux - Expect command in bash script -

i meet problem executing expect command bash variable. have location given parameter of script , need utilize in send command via expect -c. need give " send command thinking i've ended typing , recognizing rest of command characters after close-quote. thing like:

#!/bin/bash sign=ppp expect -cd 'spawn ssh user@host expect "password:" send -- "pass\r" expect "*~>" send -- "find /local/"$sign"/ -maxdepth 1 -type d -mtime +30 |xargs rm -rfv\r" expect "*~>" send -- "exit\r"'

any thought how send variable bash expect without double-quotes? btw - cannot utilize keys ssh

you can escape '"$sign"':

ex:

#!/bin/bash sign=ppp expect -c 'spawn ssh tiago@localhost expect "password:" send -- "mypass\r" expect "~" send -- "echo '"$sign"'\r" expect "^ppp" send -- "exit\r"'

i trying implement flatuikit in custom cell in uitableview within viewcontroller returns values nsuserdefaults based on switch state. usual switch, have method 'saveswitchstate' connected valuechanged outlet. problem in want pass state user defaults , utilize label key, method can't access the cells , labels. have tried adding:

static nsstring *cellidentifier = @"cell"; setuponecell *cell = (setuponecell *)[tableview dequeuereusablecellwithidentifier:cellidentifier forindexpath:indexpath];

to method, still no luck. if there improve way save switch states valuechanged method i'm ears. below viewcontroller , custom cell.

viewcontroller.m:

#import "setup1viewcontroller.h" #import "setup1tableview.h" #import "setuponecell.h" #import "social.h" #import "fuiswitch.h" #import "uifont+flatui.h" #import "uicolor+flatui.h" @interface setup1viewcontroller () - (ibaction)saveswitchstate:(id)sender; @end @implementation setup1viewcontroller - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil { self = [super initwithnibname:nibnameornil bundle:nibbundleornil]; if (self) { // custom initialization } homecoming self; } - (void)viewdidload { [super viewdidload]; self.onetableview.datasource = self; self.onetableview.delegate = self; self.medias = [[nsmutablearray alloc] init]; social *media = [[social alloc] init]; media.socialmedia = @"facebook"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"twitter"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"instagram"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"tumblr"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"gmail"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"linked in"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"github"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"you tube"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"vine"; [self.medias addobject:media]; media = [[social alloc] init]; media.socialmedia = @"soundcloud"; [self.medias addobject:media]; //self.setup1table.editing = yes; } - (void)didreceivememorywarning { [super didreceivememorywarning]; // dispose of resources can recreated. } #pragma mark - table view info source - (nsinteger)numberofsectionsintableview:(uitableview *)tableview { homecoming 1; } - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { homecoming [self.medias count]; } - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { static nsstring *cellidentifier = @"cell"; setuponecell *cell = (setuponecell *)[tableview dequeuereusablecellwithidentifier:cellidentifier forindexpath:indexpath]; cell.cellswitch.oncolor = [uicolor turquoisecolor]; cell.cellswitch.offcolor = [uicolor cloudscolor]; cell.cellswitch.onbackgroundcolor = [uicolor midnightbluecolor]; cell.cellswitch.offbackgroundcolor = [uicolor silvercolor]; cell.cellswitch.offlabel.font = [uifont boldflatfontofsize:14]; cell.cellswitch.onlabel.font = [uifont boldflatfontofsize:14]; social *media = (self.medias)[indexpath.row]; cell.socialname.text = media.socialmedia; homecoming cell; } - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath { return; } - (ibaction)saveswitchstate:(id)sender { nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; if ([cell.cellswitch ison]) [defaults setbool:yes forkey:celllabel]; else [defaults setbool:no forkey:celllabel]; } @end

setuponecell.h:

#import <uikit/uikit.h> #import "fuiswitch.h" #import "uifont+flatui.h" #import "uicolor+flatui.h" @interface setuponecell : uitableviewcell @property (weak, nonatomic) iboutlet uilabel *socialname; @property (weak, nonatomic) iboutlet fuiswitch *cellswitch; @end

the basic thought have cell hear switch value changing, study alter view controller through delegate call. in view controller can info associated cell , utilize modify nsuserdefaults.

how this:

inside cell's setup code should add together cell target switch, instead of having view controller target. (probably in cell's -awakefromnib work in sort of -configurewithsocialmedia: method.)

- (void)awakefromnib { [self.cellswitch addtarget:self action:@selector(switchvaluechanged:) forcontrolevents:uicontroleventvaluechanged]; } - (void)switchvaluechanged:(id)sender { [self.delegate setuponecell:self witchvaluedidchange:[self.cellswitch ison]]; }

then create protocol method -setuponecell:switchvaluedidchange: passes cell , switch value. create cell take delegate follows protocol.

code protocol:

@protocol setuponecelldelegate; @interface setuponecell : uitableviewcell @property (weak, nonatomic) iboutlet uilabel *socialname; @property (weak, nonatomic) iboutlet fuiswitch *cellswitch; @property (weak, nonatomic) id<setuponecelldelegate> delegate; @end @protocol setuponecelldelegate <nsobject> - (void)setuponecell:(setuponecell *)cell switchvaluedidchange:(bool)switchvalue; @end

now view controller set callback cell when switch value changes. when configure cell, create sure set view controller delegate:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { static nsstring *cellidentifier = @"cell"; setuponecell *cell = (setuponecell *)[tableview dequeuereusablecellwithidentifier:cellidentifier forindexpath:indexpath]; cell.cellswitch.oncolor = [uicolor turquoisecolor]; cell.cellswitch.offcolor = [uicolor cloudscolor]; cell.cellswitch.onbackgroundcolor = [uicolor midnightbluecolor]; cell.cellswitch.offbackgroundcolor = [uicolor silvercolor]; cell.cellswitch.offlabel.font = [uifont boldflatfontofsize:14]; cell.cellswitch.onlabel.font = [uifont boldflatfontofsize:14]; social *media = (self.medias)[indexpath.row]; cell.socialname.text = media.socialmedia; cell.delegate = self; homecoming cell; }

and implement delegate method:

- (void)setuponecell:(setuponecell *)cell switchvaluedidchange:(bool)switchvalue { nsindexpath *indexpath = [self.onetableview indexpathforcell:cell]; nsstring *label = [self.medias[indexpath.row] socialmedia]; nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; [defaults setbool:switchvalue forkey:label]; }

i've tried searching , haven't found duplicate/similar question.

how come "default" never triggering in case? working on previous homework assignments course of study prepare fall, , i'm having issue getopt() in c.

here particular lines in question:

while ((c = getopt(argc, argv, "i:o:")) != -1) { switch (c) { case 'i': infile = strdup(optarg); break; case 'o': outfile = strdup(optarg); break; default: usage(); //this prints "usage" statement , exits cleanly. } }

my issue is, how come calling

./fastsort b c d

doesn't print usage , exit?

the below code search options -i hello or/and -o world

while((c = getopt(argc, argv, "i:o:") != -1)

however executing is:

./fastsort b c d

where getopt(argc, argv, "i:o:") != -1 not satisfied since none of passed argument a b c dis option

google drive sdk - How to handle if else in Dart Future -

i need google drive folder's fileid. if folder not exist, need create folder name , homecoming fileid. fileid, need other works.

the google drive api in dart ok me, can create folder dart. question future. code follow:

class="lang-dart prettyprint-override"> drive.files.list(q:"title='test'").then((result){ if(result.items.length == 0) { driveclient.file file = new driveclient.file.fromjson({"title":"test", "mimetype": "application/vnd.google-apps.folder"}); drive.files.insert(file).then((result2) { homecoming result2.id; }); } else { homecoming result.items[0].id; } });

when test exists, id returned. if test doesn't, function error because no return.

how that?

thanks in advance.

you need homecoming future method phone call in line 4:

class="lang-dart prettyprint-override">drive.files.list(q:"title='test'").then((result){ if(result.items.length == 0) { driveclient.file file = new driveclient.file.fromjson({"title":"test", "mimetype": "application/vnd.google-apps.folder"}); homecoming drive.files.insert(file).then((result2) { homecoming result2.id; }); } else { homecoming result.items[0].id; } });

then() returns new future there completes value returned method give parameter method. then() smart plenty resolve nested future's handle value within then() method , never instance of future.

var request = $.ajax({ url: "@url.action("getbdos", "dpadmin")", type: "get", cache: false, async: true, datatype: "json" }); request.done(function (results) { var thegrid = $("#grid"); thegrid.cleargriddata(); (var = 0; < 100; i++) { thegrid.addrowdata(i + 1, results[i]); } thegrid.trigger("reloadgrid"); }); }

which calls this:

[authorize] public jsonresult getbdos() { list<bdo> bdos= new list<bdo>(); // bdos bdos = webinterface.getbdos(); var jsonresult = json(bdos.toarray(), jsonrequestbehavior.allowget); jsonresult.maxjsonlength = int.maxvalue; homecoming jsonresult; }

webinterface.getbdos hits database , grabs current bdo objects, between 20,000 - 25,000 , freezes grid. help this?

you should paginating info on server side before sending browser. need fetch next/prev page , redraw grid.

MongoDB MapReduce--is there an Aggregation alternative? -

MongoDB MapReduce--is there an Aggregation alternative? -

i've got collection documents using schema (some members redacted):

{ "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : [ 2, 3, 5 ], "activity" : [ 4, 4, 3 ], }, "media" : [ objectid("537ea185df872bb71e4df270"), objectid("537ea185df872bb71e4df275"), objectid("537ea185df872bb71e4df272") ] }

in schema, first, second, , 3rd positivity ratings correspond first, second, , 3rd entries in media array, respectively. same true activity ratings. need calculate statistics positivity , activity ratings respect associated media objects across documents in collection. right now, i'm doing mapreduce. i'd to, however, accomplish aggregation pipeline.

ideally, i'd $unwind media, answers.ratings.positivity, , answers.ratings.activity arrays simultaneously end with, example, next 3 documents based on previous example:

[ { "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : 2, "activity" : 4 } }, "media" : objectid("537ea185df872bb71e4df270") }, { "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : 3 "activity" : 4 } }, "media" : objectid("537ea185df872bb71e4df275") }, { "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : 5 "activity" : 3 } }, "media" : objectid("537ea185df872bb71e4df272") } ]

is there way accomplish this?

the current aggregation framework not allow this. beingness able unwind multiple arrays know same size , creating document ith value of each feature.

if want utilize aggregation framework need alter schema little. illustration take next document schema:

{ "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : [ {k:1, v:2}, {k:2, v:3}, {k:3, v:5} ], "activity" : [ {k:1, v:4}, {k:2, v:4}, {k:3, v:3} ], }}, "media" : [ {k:1, v:objectid("537ea185df872bb71e4df270")}, {k:2, v:objectid("537ea185df872bb71e4df275")}, {k:3, v:objectid("537ea185df872bb71e4df272")} ] }

by doing adding index object within array. after it's matter of unwinding arrays , matching on key.

db.test.aggregate([{$unwind:"$media"}, {$unwind:"$answers.ratings.positivity"}, {$unwind:"$answers.ratings.activity"}, {$project:{"media":1, "answers.ratings.positivity":1,"answers.ratings.activity":1, include:{$and:[ {$eq:["$media.k", "$answers.ratings.positivity.k"]}, {$eq:["$media.k", "$answers.ratings.activity.k"]} ]}} }, {$match:{include:true}}])

and output is:

[ { "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : { "k" : 1, "v" : 2 }, "activity" : { "k" : 1, "v" : 4 } } }, "media" : { "k" : 1, "v" : objectid("537ea185df872bb71e4df270") }, "include" : true }, { "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : { "k" : 2, "v" : 3 }, "activity" : { "k" : 2, "v" : 4 } } }, "media" : { "k" : 2, "v" : objectid("537ea185df872bb71e4df275") }, "include" : true }, { "_id" : objectid("539f41a95d1887b57ab78bea"), "answers" : { "ratings" : { "positivity" : { "k" : 3, "v" : 5 }, "activity" : { "k" : 3, "v" : 3 } } }, "media" : { "k" : 3, "v" : objectid("537ea185df872bb71e4df272") }, "include" : true } ]

doing creates lot of document overhead , may slower current mapreduce implementation. need run tests check this. computations required grow in cubic way based on size of 3 arrays. should kept in mind.

node.js - Backend server app which listens to multiple Server Sent Events and saves data to DB -

node.js - Backend server app which listens to multiple Server Sent Events and saves data to DB -

what best tool/way implement server side application hear multiple server sent events(sse) , action saving values database on receiving events. number of sse listeners alter new users gets registered. considering node.js, please help me thoughts on implementing not server application development background.

i think best solution here -if considering nodejs- utilize websockets. can utilize socket.io , set on own or utilize paas take of you, example: http://pusher.com/.

using websockets can seamlessly communicate client (browser) , and send , receive info in real time. can applied other device capable of doing http connections.

to store values utilize redis, quite fast , should give simple , basic functionality looking for. if actions need atomic, can build simple worker process write values redis database, postgresql instance.

Variable within a Variable in Bash -

Variable within a Variable in Bash -

can not figure out. can't figure out variable within variable. also, how quiet output if host down.

#/bin/bash ip in `cat list`; output=$( $name=`snmpwalk -v 2c -c snmp2 $ip snmpv2-mib::sysname.0 | grep -o '[^ ]*$'` $type=`snmpwalk -v 2c -c snmp2 $ip snmpv2-smi::mib-2.47.1.1.1.1.13.1 | grep -o '[^ ]*$'` $soft=`snmpwalk -v 2c -c snmp2 $ip 1.3.6.1.2.1.1.1.0 | grep -i ios | awk -f, '{print $2,$3}'` ) if [ $? -eq 0 ]; echo $ip,echo $output[$name][$type][$soft] else echo $ip,null fi done

$name=value wrong. in bash it's name=value.

the $name etc. variables declared in subshell, won't available in outside code.

some other issues code:

it checks exit code of last snmpwalk. utilize set -o errexit own sanity. use $(foo) command substitutions. `foo` obsolete. use more quotes! useless utilize of cat award awarded. use portable shebang line (disclaimer: own answer) echo foo,echo bar print foo,echo bar. ; line separator, whenever sense tempted utilize add together newline clarity.

line 5 on method causing error, seems listing undefined. why case when subscribed listing on route calls method. need create server method?

when phone call method

meteor.call("addtocart", (quantity, listingid, cartid), function(err, res){

you shouldn't have ( ) around quantity, listingid, cartid:

meteor.call("addtocart", quantity, listingid, cartid, function(err, res){

when write f(a, (b, c, d), e), (b, c, d) comma operator, evaluates operands, returns lastly one. same f(a, d, e).

thank you!

in jsfiddle, if you're going phone call functions in events, need declare variables window.show , window.hide because script set within window.onload method:

window.show = function() { document.queryselector('.pop').style.visibility = 'visible'; } window.hide = function() { document.queryselector('.pop').style.visibility = 'hidden'; }

if want to, can alter wrap on left side of jsfiddle. alternative no wrap - in <body> puts script in global scope, before closing of body tag.

numpy - python equivalent of MATLAB statement A(B==1)= C -

numpy - python equivalent of MATLAB statement A(B==1)= C -

i have 3 numpy arrays follows:

a = [1, 2, 3, 4, 5] b = [0, 1, 0, 0, 1] c = [30, 40]

i replace elements of equivalent in b equal 1. above illustration this:

a = [1, 30, 3, 4, 40]

in matlab, can this:

a(b==1) = c'

do know equivalent code in python (preferably works when , b multidimensional too)? in advance.

the syntax pretty similar:

>>> import numpy np >>> = np.array([1, 2, 3, 4, 5]) >>> b = np.array([0, 1, 0, 0, 1]) >>> c = np.array([30, 40]) >>> a[b==1] = c >>> array([ 1, 30, 3, 4, 40])

xcode - Objective C general troubleshooting process -

xcode - Objective C general troubleshooting process -

i'm 2 weeks learning objective-c (but previous experience java , python), , after initial hurdle i'm starting hang of things pointers, arc, , delegates. however, on more 1 occasion i've come across problem/bug have no thought how solve, , worse, have no thought how approach solution.

my general troubleshooting strategy, when things aren't working expected, follows:

reread through relevant section of code create sure general logic , flow makes sense look @ self-defined methods , create sure they're working properly put few nslog statements within code see doing unexpected things once i've identified troublesome part(s), search apple docs/stackoverflow/google see if has experienced same problems.

i might omitting step , general process works part. however, there problems come across process not work, , totally stuck. few examples:

i trying load nswindowcontroller using proper method called in proper location, wasn't displaying. turned out issue pointers, after long time of aimless experimenting i'm testing illustration pulled straight apple technical q&a create clickable hyperlink nsattributedstring, when hover on said link pointing hand cursor not appear. see my thread more info. i've created nsbutton , want pointing hand cursor appear when hover on button. i'm using code in accepted reply here, doesn't work , don't know why. also, subclassing every button want utilize tedious , messy.

clearly troubleshooting strategy not working. 1 time exhaust 4 steps no avail, have seek random fixes until one, seemingly magically, works. neither time efficient nor helping me understand language better. there steps can add together troubleshooting strategy, , if so, they?

for example, when asked friend same question, suggested using breakpoints monitor instance variables , objects.

when across bug,

first thing need read error, see error , occurred. go specific location of error, see if there obvious mistake. if not, set break point @ skeptical location, step in , check step step see if each value on stack expected be. you may want set test, consider possibilities, such if value null, if it's 0, etc.

sometimes bugs tricky, not recommended read code on 1 time again each time see error.

view - Share data in every subview -

view - Share data in every subview -

i have created layout contains header , main content changes regularly.

@include('tshop.includes.header') @yield('content') @include('tshop.includes.footer')

i have created below view composer in order pass products in basket pop dialog in header.

view::composer('tshop.includes.header', function($view) { $basket = app::make('basketinterface'); $view->with( 'productsiterator' , $basket->getiterator() ); });

the thing want share in views, including main content.

i tried utilize share (and shares) function thinking same view::share isn't.

view::composer('tshop.includes.header', function($view) { $basket = app::make('basketinterface'); $view->share( 'productsiterator' , $basket->getiterator() ); });

i tried utilize view composer layout in vain.

view::composer('tshop.layouts.default', function($view) { $basket = app::make('basketinterface'); $view->shares( 'productsiterator' , $basket->getiterator() ); });

next placed below filter constructor.

$this->beforefilter(function() { $basket = app::make('basketinterface'); view::share('productsiterator' , $basket->getiterator()); });

and worked, utilize several controllers, it's not best thing do. know can create base of operations controller class , extend isn't there improve way do?

you may utilize app::before event share info views globally using view::share, example:

app::before(function($request) { $basket = app::make('basketinterface'); view::share( 'productsiterator' , $basket->getiterator() ); });

now, may access $productsiterator view , btw, have used shares instead of share. may utilize view composer instead of using view::share, this:

view::composer('tshop.includes.header', function($view) { $basket = app::make('basketinterface'); homecoming $view->with( 'productsiterator' , $basket->getiterator() ); });

in case need utilize $view->with() method instead of share.

yii - Construct CDbCriteria with column names as MySQL reserved words -

yii - Construct CDbCriteria with column names as MySQL reserved words -

i have same problem in this question (attempt utilize cdbcriteria column named key, reserved word in mysql). however, provided solution:

$criteria = new cdbcriteria; $criteria->condition = 't.key=:key'; $criteria->params = array(':key'=>$this->key); $criteria->compare('position', $this->position); $criteria->compare('dictionary', $this->dictionary);

works me partially. don't exception anymore, search works key column only. other ignored (if key set, respects value in search, if not set -- returns empty results set).

what missing? how should build cdbcriteria queries, when table contains reserverd words column names, search respect other (non-reserved) columns well, not one?

cdbcriteria::compare() adds status if parameter set otherwise no action taken.see here

$criteria->condition = 't.key=:key'; $criteria->params = array(':key'=>$this->key);

however logic works irrespective of whether key set or not. status becomes

select * `some_table` t t.key =:key

even though key value beingness blank resulting in query breaking when key attribute not set

so if modify statement work

if(isset($this->key){ $criteria->condition = 't.key=:key'; $criteria->params = array(':key'=>$this->key); }

in case statement activated when key attribute set, ignored otherwise, , query not break

c++ - Why does unique_ptr overload reset(pointer p = pointer()) and reset(nullptr_t)? -

c++ - Why does unique_ptr overload reset(pointer p = pointer()) and reset(nullptr_t)? -

accroding http://en.cppreference.com/w/cpp/memory/unique_ptr/reset,

void reset( pointer ptr = pointer() ); template< class u > void reset( u ) = delete; void reset( std::nullptr_t p );

1) given current_ptr, pointer managed *this, performs next actions, in order: saves re-create of current pointer old_ptr = current_ptr; overwrites current pointer argument current_ptr = ptr; if old pointer non-empty, deletes managed object if(old_ptr != nullptr) get_deleter()(old_ptr).

2) in specialization dynamic arrays, std::unique_ptr<t[]>, template fellow member provided prevent using reset() pointer derived (which result in undefined behavior arrays).

3) in specialization dynamic arrays, std::unique_ptr<t[]>, 3rd overload necessary allow reset nullptr (which otherwise prohibited template overload). equivalent reset(pointer())

now reset(nullptr) equivalent reset(pointer()), why latter exist?

if want reset array form unique_ptr, why can not utilize rest(pointer())?

the

template< class u > void reset( u ) = delete;

would chosen phone call nullptr argument, if not for

void reset( std::nullptr_t p );

that's why exists, allow phone call nullptr.

example (compile fix defined suppress compilation error):

#include <cstddef> // std::nullptr_t struct s { void reset( char* ) {} template< class type > void reset( type ) = delete; #if prepare void reset( std::nullptr_t ) {} #endif }; auto main() -> int { s().reset( nullptr ); // fails when prepare not defined. }

Parsing values from a JSON file in Python -

Parsing values from a JSON file in Python -

i have json in file:

{ "maps": [ { "id": "blabla", "iscategorical": "0" }, { "id": "blabla", "iscategorical": "0" } ], "masks": [ "id": "valore" ], "om_points": "value", "parameters": [ "id": "valore" ] }

i wrote script prints of json text:

json_data=open(file_directory).read() info = json.loads(json_data) pprint(data)

how can parse file , extract single values?

i think ignacio saying json file incorrect. have []s when should have {}s. []s lists, {}s dictionaries. here's how json file should (your json file wouldn't load me):

{"maps":[{"id":"blabla","iscategorical":"0"},{"id":"blabla","iscategorical":"0"}], "masks":{"id":"valore"}, "om_points":"value", "parameters":{"id":"valore"} }

then can utilize code:

import json pprint import pprint open('data.json') data_file: info = json.load(data_file) pprint(data)

with data, can find values in so:

data["maps"][0]["id"] data["masks"]["id"] data["om_points"]

try out , see if starts create sense.

background: have method bunch of fiddling copies of giant lists , running our of memory. of in single method scope.

question: luckily need original giant list @ origin of method. in method, setting list null allow garbage collecting it? or jit or compiler automatically dereference variable sees no longer used? i'm thinking minor optimization allow before garbage collection.

there no need nullify variable. article on garbage collection (that worth read) can found here. looking section labeled "explicit nulling"

this appears bug csv parser, firstly works:

df = pd.read_csv('mqm q.csv')

also works:

df = pd.read_csv('mqm q.csv', usecols=['value'])

but if want date-time fails same error message yours.

so noticed utf-8 encoded , converted using notepad++ ansi , worked, tried utf-8 without bom , worked.

i converted utf-8 (presumably there bom) , failed same error before, don't think imaging , looks bug.

i using python 3.3, pandas 0.14 , numpy 1.8.1

to around this:

df = pd.read_csv('mqm q.csv', usecols=[0,1], parse_dates=true, dayfirst=true, index_col=0)
