ruby on rails 3 - Railscast #238 jquery token input - My json request is going to the wrong controller -

hi i'm trying implement jquery token input according railscasts #258 http://railscasts.com/episodes/258-token-fields

where railscasts uses 'author' using 'artist'

when start typing in artist_token field json search request processed userscontroller#show action instead of artistscontroller#index action.

since _post_form partial rendered on pagescontroller#home view have thought json might processed pagescontroller#home reason userscontroller#show

any ideas i'm doing wrong?

## working example railscasts #258  started "/authors.json?q=d" 127.0.0.1 @ 2011-07-03 16:27:31 -0700   processing authorscontroller#index json   parameters: {"q"=>"d"}   author load (0.7ms)  select "authors".* "authors" (name '%d%') completed 200 ok in 17ms (views: 2.3ms | activerecord: 0.7ms)   ## log userscontroller#show instead of artistscontroller#index ???  started "/artists.json?q=d" 127.0.0.1 @ 2011-07-03 16:12:44 -0700   processing userscontroller#show json   parameters: {"q"=>"d", "id"=>"artists.json"}   user load (0.3ms)  select "users".* "users" "users"."cached_slug" = 'artists.json' limit 1   sql (0.1ms)  select sluggable_id slugs ((slugs.sluggable_type = 'user' , slugs.name = 'artists.json' , slugs.sequence = 1))   user load (0.1ms)  select "users".* "users" "users"."id" = 0 limit 1 redirected http://localhost:3000/ completed 302 found in 133ms  ## pages controller  class pagescontroller < applicationcontroller    def home     @title = "home"     @featured_posts = post.featured.limit(10)     if user_signed_in?       @user = current_user       @post = current_user.posts.build       @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])     else      #render :layout => 'special_layout'      end   end  ## views/pages/home.html.erb   <% if user_signed_in? %>     <%= render 'shared/post_form'%>     <%= render 'shared/user_info' %>    <%= render 'shared/stats' %>  ## views/shared/_post form.html.erb  <%= form_for @post, :validate => true, :html => {:multipart => true} |f| %>   <%= render 'shared/error_messages', :object => f.object %>     <div class="field">     <%= f.label :title, 'title:' %><br />          <%= f.text_field :title %><br />       <%= f.label :artist_tokens, "artists" %><br />      <%= f.text_field :artist_tokens, "data-pre" => @post.artists.map(&:attributes).to_json %>     <div>     <div class="actions">       <%= f.submit "submit" %>     </div> <% end %>   ## artists controller  class artistscontroller < applicationcontroller   def index     @artists = artist.where("name ?", "%#{params[:q]}%")     respond_to |format|       format.html       format.json { render :json => @artists.map(&:attributes) }     end   end    def show     @artist = artist.find(params[:id])   end    def new     @artist = artist.new   end    def create     @artist = artist.new(params[:author])     if @artist.save       redirect_to @artist, :notice => "successfully created artist."     else       render :action => 'new'     end   end    def edit     @artist = artist.find(params[:id])   end    def update     @artist = artist.find(params[:id])     if @artist.update_attributes(params[:artist])       redirect_to @artist, :notice  => "successfully updated artist."     else       render :action => 'edit'     end   end    def destroy     @artist = artist.find(params[:id])     @artist.destroy     redirect_to authors_url, :notice => "successfully destroyed artist."   end end   ## artist model  class artist < activerecord::base attr_accessible :name has_many :artistizations has_many :posts, :through => :artistizations  end  ## artistization model  class artistization < activerecord::base attr_accessible :post_id, :artist_id belongs_to :artist belongs_to :post  end  ## post model    attr_accessible :title, :artist_tokens    has_many :artistizations   has_many :artists, :through => :artistizations    attr_reader :artist_tokens    def artist_tokens=(ids)     self.artist_ids = ids.split(",")   end   ## application.js  $(function() {   $("#post_artist_tokens").tokeninput("/artists.json", {     crossdomain: false,     prepopulate: $("#post_artist_tokens").data("pre"),     theme: "facebook"    }); });   ## routes      match 'auth/:provider/callback' => 'authentications#create'   resources :authentications    devise_for :admins   match '/admin' => 'railsadmin/main#index'    devise_for :users, :controllers => {:registrations => 'registrations'}    resources :posts       member       :likers       end       collection         :search       end   end      resources :relationships, :only => [:create, :destroy]   resources :appreciations, :only => [:create, :destroy]     match '/contact', :to => 'pages#contact'   match '/about',   :to => 'pages#about'   match '/help',    :to => 'pages#help'   match '/blog',    :to => 'pages#blog'     resources :users      member      :following, :followers, :likes      end      resources :collections  end    # legacy wild controller route that's not recommended restful applications.   # note: route make actions in every controller accessible via requests.   # match ':controller(/:action(/:id(.:format)))'     match '/:id' => 'users#show', :constraints => {:id => /[^\/]+/}, :as => :global_user     root :to => "pages#home" end 

usually when have problems these, being processed 'wrong' controller, should first check routes.rb file.

right away noticed this:

# legacy wild controller route that's not recommended restful applications. # note: route make actions in every controller accessible via requests. # match ':controller(/:action(/:id(.:format)))' match '/:id' => 'users#show', :constraints => {:id => /[^\/]+/}, :as => :global_user 

basically seems every request in format being routed users#show action. try commenting out match directive , see if works now. if other things break it's see why need there , how can accommodate accordingly.
