Rails not use application.html.erb

Question

I know that by default, views in Rails use the template provided in application.html.erb. However, there's one view that I wouldn't like to use the template provided in application.html.erb, but rather write all the HTML in that view itself. Is that possible to do?

Answer 1

At the end of your controller action, add:

render :layout => false

Answer 2

For a specific action:

class SomeController < ApplicationController
  def my_custom_action
    render layout: false
  end
end

Answer 3

You can achieve the same thing using custom layouts.

e.g. For WelcomeController

1. Create a custom layout file named welcome.html.erb in app/views/layout/. Write your layout code there(don't forget the yield). Due to rails Convention over Configuration feature when rails renders any view mapped to WelcomeController, welcome.html.erb will override the default application.html.erb layout.

2. If you want to name your custom layout file differently. Rails allows you to do that as well. Name your layout file as mylayout.html.erb. In WelcomeController, add the following code

   class WelcomeController < ApplicationController

   layout 'mylayout'

   ....

   end

3. If you want custom layout for only a specific action, then on the last line of action write render layout: 'mylayout'

Answer 4

Sure, in your action do something like this:

def action
  render :layout => false
end

This assumes there are other actions in your controller which do need the layout. Otherwise, I would specify layout false in the controller root.

If you have multiple actions which don't need a layout, I believe you can do

layout false, :only => [ :action1, :action2 ]
