javascript - Backbone app POST request to database -

so have backbone app using rails 4 on backend. there 2 models, articles , publications. have post requests nested since need info comes publications post insert data object the articles post. when make post request articles controller send the following data object: url, publication_id , publication_name. reason when @ rails console @ articles created see url , publication_id populated not publication_name. code pasted here. ideas how publication_name show up?

publications_index.js

createfeed: function(e){     e.preventdefault();     var feed_url = $('#new_feed_name').val();     // var = this;      this.collection.create(       { url: feed_url       },       { success: function(data){         var name = data.attributes.name;         $.post('/articles/force_update', {url: feed_url, publication_id: data.id, publication_name: name}, function(data){           });         }       }     );    } 

schema.rb

  create_table "articles", force: true |t|     t.string   "name"     t.integer  "publication_id"     t.datetime "created_at"     t.datetime "updated_at"     t.text     "summary"     t.string   "url"     t.datetime "published_at"     t.string   "guid"     t.integer  "user_id"     t.string   "publication"     t.string   "publication_name"   end 

article.rb

    def self.update_from_feed(feed_url, publication_id, user, publication_name)     feed = feedzirra::feed.fetch_and_parse(feed_url)     feed.entries.each |entry|       unless exists? :guid => entry.id         create!(           :name             => entry.title,           :summary          => entry.summary,           :url              => feed_url,           :published_at     => entry.published,           :guid             => entry.id,           :publication_id   => publication_id,           :user_id          => user.id,           :publication_name => publication_name         )       end     end   end 

articles_controller.rb

  def force_update     article.update_from_feed( params[:url], params[:publication_id], current_user, params[:publication_name] )     render :text => "success"   end 

and

private     # use callbacks share common setup or constraints between actions.     def set_article       @article = article.find(params[:id])     end      # never trust parameters scary internet, allow white list through.     def article_params       params.permit(:name, :publication_id, :created_at, :updated_at, :summary, :url, :published_at, :guid, :publication_name)     end 

you need return article value, e.g.

  def force_update     article.update_from_feed( params[:url], params[:publication_id], current_user, params[:publication_name] )     respond_with(@article)   end 

of course, supposes have controller set respond_to json format. in addition, you'd typically want return status in addition data. above should return data want...
