ruby on rails - undefined method `popups_path' for # -

i create model, view , controller when added form code on new.html.haml file. started showing error. routes defined follows

model popups.rb

class popups < activerecord::base   attr_accessible :title, :body, :slug, :pipelinetype end 

controller popups_controller.rb

class popupscontroller < applicationcontroller   def new     @popups = popups.new   end    def create     @popups = popups.new(params[:url])     if @popups.save       flash[:popups] = @popups.id       redirect_to new_popups_url     else       render :action => "new"     end   end    def show     @popups = popups.find(params[:id])     redirect_to @popups.url   end  end 

views popups - new.html.haml

= simple_form_for @popups |f|   = f.input :title   = f.input :body   = f.input :pipelinetype   = f.input :slug   = f.submit 

routes.rb resources :popups, :only => [:show, :new, :create]

migrate file

create_table :popups |t|       t.string :title       t.text :body       t.string :slug       t.string :pipelinetype        t.timestamps     end 

i getting following errors on given urls

:3000/popups/new  -  undefined method `popups_index_path' #  **:3000/popups   -**   unknown action action 'show' not found maincontroller 

initially created model , controller popup name change later popups suggested

is there wrong code or routes or missing someting.

i used http://www.sitepoint.com/building-your-first-rails-application-views-and-controllers/ reference

always remember when use resources, should giving plural name(i.e, popups in case). if want singular name(i.e, popup) use resource instead of resources.

for more info, see singular resources
