How to tell Devise to render it's views in another layout?

Question

Devise继续在默认的views/layouts/application.html.erb布局中呈现它的登录表单，但我希望它使用Administrate布局，我该如何实现？

Answer 1

In your particular case this applies:

To have Devise use a separate layout to the rest of your application, you could do something like this:

class ApplicationController < ActionController::Base
  layout :layout_by_resource

  protected

  def layout_by_resource
    if devise_controller?
      "layout_name_for_devise"
    else
      "application"
    end
  end
end

Answer 2

Solution-1:

Overide devise SessionsController with your custom session controller and set layout: :adminstrator

Solution-2

In ApplicationController :

layout: custom_layout

def custom_layout
    params[:controller] == "sessions" ? "adminstrator" : "application"
end

Hope it helps!
