Fixing error for controller

Let’s try to understand error here.

The error says that our application doesn’t have constant (or class in this case) with name IdeasController. Let’s fix this by creating a controller with file name ideas_controller.rb under app/controllers folder.

# app/controller/ideas_controller.rb
class IdeasController < ApplicationController
end

Now, the above error should be fixed but we will different error.

Unknown action

The action 'show' could not be found for IdeasController

This error says that we don’t have action (or method in terms of programming) inside IdeasController.

Updated the IdeasController with method show as:

# app/controller/ideas_controller.rb
class IdeasController < ApplicationController
  def show
  end
end

Template error

The error related to controller has gone and we are now getting following error which is related to view:

No template for interactive request

IdeasController#show is missing a template for request formats: text/html
