Title Body

My setup: Rails 3.0.9, Ruby 1.9.2 I added a custom action to a nested resource task. routes.rb resources :tasks resources :projects do resources :tasks, :constraints => { :protocol => "http" } do put :cancel, :on => :member end end rake routes shows cancel_project_task PUT /projects/:task_id/tasks/:id/cancel(.:format) {:protocol=>"http", :action=>"cancel", :controller=>"tasks"} In my controller, tasks_controller.rb def cancel @task = Task.find(params[:id]) respond_to do |format| if @task.cancel format.html { redirect_to(@task, :notice => 'Task was successfully canceled.') } else format.html { render :action => "edit" } end end end I need to define a form to perform the action, here's what I have currently _form.html.erb for subscription <%= form_for [@project, @task], :url => { :action => 'cancel' } do |f| %> <%= f.submit "Cancel your task"%> <% end %> It throws an error No route matches {:action=>"cancel", :controller=>"tasks"} I also tried adding :method => "put" with the same error _form.html.erb for subscription <%= form_for [@project, @task], :url => { :action => 'cancel', :method => "put" } do |f| %> <%= f.submit "Cancel your task"%> <% end %> Anyone knows the correct form_format syntax to accomplish this?
