Retrieve associations in AngularJS & Rails using ngResource -

i have record & category model:

class record < activerecord::base     belongs_to :category end  class category < activerecord::base     has_many :records end 

the category model has name field should used display. using ng-repeat display records, 'record.category.name' causes page break:

<tr ng-repeat="record in records">     <td>{{record.category.name)}}</td>     <td>{{record.description}}</td>     <td>{{record.created_at | date:'medium'}}</td> </tr> 

how can retrieve 'record.category' 'name' field available have above? using ngresource far has not populated associations.

i retrieving record model using ngresource:

            var record = $resource('/records/:recordid', {                 recordid:'@id',                 format: 'json'             }, {                 'save': {                     method: 'put'                 },                 'create': {                     method: 'post'                 }             });              record.query({                     account_id: $routeparams.accountid             }, function(results) {                     return $scope.records = results;             }); 

how can retrieve model in angularjs association data available display well?

edit:

index.json.jbuilder

json.array! @records, partial: 'record', as: :record 

_record.json.jbuilder

json.(record, :id, :account_id, :user_id, :amount, :date, :description, :is_expense, :category_id, include: [:category]) 

this isn't angular issue, it's rails (and api design) issue. reason api design because depending on use case may more efficient client fetch categories , work in front end match categories records. said, you're trying need change rails app.

modified code linked answer:

def show   @record = record.find(params[:id])   respond_to |format|     format.json { render :json => @record.to_json(:include => :category) }   end end 

back when doing rails :include in find call haven't done rails time. don't know if that's still best way it.
