How to add a custom action to the controller in Rails 3

I want to add another action to my controller, and I can't figure out how.

I found this on RailsCasts, and on most StackOverflow topics:

# routes.rb
resources :items, :collection => {:schedule => :post, :save_scheduling => :put}

# items_controller.rb
  ...
  def schedule
  end

  def save_scheduling
  end

# items index view:
<%= link_to 'Schedule', schedule_item_path(item) %>

But it gives me the error:

undefined method `schedule_item_path' for #<#<Class:0x6287b50>:0x62730c0>

Not sure where I should go from here.

A nicer way to write

resources :items, :collection => {:schedule => :post, :save_scheduling => :put}

is

resources :items do
  collection do
    post :schedule
    put :save_scheduling
  end
end

This is going to create URLs like

  • /items/schedule
  • /items/save_scheduling

Because you're passing an item into your schedule_... route method, you likely want member routes instead of collection routes.

resources :items do
  member do
    post :schedule
    put :save_scheduling
  end
end

This is going to create URLs like

  • /items/:id/schedule
  • /items/:id/save_scheduling

Now a route method schedule_item_path accepting an Item instance will be available. The final issue is, your link_to as it stands is going to generate a GET request, not a POST request as your route requires. You need to specify this as a :method option.

link_to("Title here", schedule_item_path(item), method: :post, ...)

You can write routes.rb like this:

match "items/schedule" => "items#schedule", :via => :post, :as => :schedule_item
match "items/save_scheduling" => "items#save_scheduling", :via => :put, :as => :save_scheduling_item

And the link_to helper can not send post verb in Rails 3.

Ref Rails Routing from the Outside In

Following should work

resources :items do
  collection do
    post 'schedule'
    put 'save_scheduling'
  end
end
