json - Backbone.js: model relationships -

i have newsletter can represented next json model. i'd build newsletter editor allows drag/drop moving of entries (articles), ability add together new entries. ultimately, json saved via api database.

var newsletter = new newsletter({ id : 1, title : 'newsletter 1', date : '17.08.2014', sections : [ { title : 'lorem ipsum dolor sit down amet', color : '831b12', subsections : [ { title : 'lorem ipsum dolor sit down amet', entries : [ { title : 'lorem ipsum dolor sit down amet', intro : 'lorem ipsum dolor sit down amet, consectetur adipiscing elit. fusce lacus mi, ullamcorper id mi non, dign...', url : '#' }, { title : 'lorem ipsum dolor sit down amet', intro : 'lorem ipsum dolor sit down amet, consectetur adipiscing elit. fusce lacus mi, ullamcorper id mi non, dign...', url : '#' } ] }, { title : 'lorem ipsum dolor sit down amet', entries : [ { title : 'lorem ipsum dolor sit down amet', intro : 'lorem ipsum dolor sit down amet, consectetur adipiscing elit. fusce lacus mi, ullamcorper id mi non, dign...', url : '#' }, { title : 'lorem ipsum dolor sit down amet', intro : 'lorem ipsum dolor sit down amet, consectetur adipiscing elit. fusce lacus mi, ullamcorper id mi non, dign...', url : '#' }, { title : 'lorem ipsum dolor sit down amet', intro : 'lorem ipsum dolor sit down amet, consectetur adipiscing elit. fusce lacus mi, ullamcorper id mi non, dign...', url : '#' } ] } ] } ] });

i unclear whether require single backbone model, newsletter, or whether need models each 'layer' (i.e. newsletter, section, subsection, entry) , model relationship somehow? have seen links backbone relational sounds promising wasn't sure whether necessary application.

most of tutorial i've seen far seem focus on todo-style apps single layer of todo items, in collection. suppose newsletter considered collection of sections, section collection of subsections etc. right path following?

thanks :)

just record, ended building in knockout.js , handled beautifully.

i able write chunks of html generated each json element type (sections, subsections , entries) formed basis of newsletter. used knockout sortable plugin allow elements reordered within parent objects whilst keeping hierachy intact (i.e. subsections moved within own section, or moved section).

hopefully find useful.
