variables - Rails no implicit conversion of Symbol into Integer -

i trying create private method counting based on database info follows.

class applicationcontroller < actioncontroller::base # prevent csrf attacks raising exception. # apis, may want utilize :null_session instead. protect_from_forgery with: :exception before_action :moderation_count private def moderation_count @count = ''; @count[:venues_pending] = venue.where(:is_approved => 0).count.to_i @count[:venues_rejected] = venue.where(:is_approved => 2).count.to_i @count[:venue_photos_pending] = venuephoto.where(:is_approved => 0).count.to_i @count[:venue_photos_rejected] = venuephoto.where(:is_approved => 2).count.to_i @count[:venue_reviews_pending] = venuereview.where(:is_approved => 0).count.to_i @count[:venue_reviews_rejected] = venuereview.where(:is_approved => 2).count.to_i end end

error:

no implicit conversion of symbol integer

you have set @count empty string with

@count = '';

so when @count[:venues_pending], ruby tries convert symbol :venues_pending integer access particular index of string @count. resulting in error no implicit conversion of symbol integer

as planning utilize instance variable @count hash, should instantiate hash rather empty string.

use @count = {}; or @count = hash.new;
