Rails Layout name inside view

问题

How can I print out the name of current layout in a view?

Example

puts controller.current_layout

Thx

回答1:

This works with Rails 3.0.7:

controller.send :_layout

Obviously, it's a private method, so use at your own risk.

回答2:

This works for me: response.layout

UPDATE: True, response.layout does not work in rails3+ thus I usually define a @layout_name variable inside each layout.

Example of application.html.haml

- @layout_name = 'application'
!!! Strict
%html
...

回答3:

<%= controller.active_layout %> gets you the layout file name. So layout 'application' would return layouts/application.html.erb

In Rails 2.1.0 and greater.
