Rails布局名称在视图中

Question

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

Example

puts controller.current_layout

Thx

Answer 1

This works with Rails 3.0.7:

controller.send :_layout

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

Answer 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
...

Answer 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 .
