是否可能无法从某个页面屈服？

Question

试图创建一个页面，它不会占用layouts / application.html.erb中的所有内容，这可能吗？

Answer 1

The following will display your content unless you are on a specific page:

yield(:something) unless controller_name == 'mycontroller' and action_name == 'myaction'

The following will output header and includes unless you are on a specific page:

if controller_name == 'mycontroller' and action_name == 'myaction'
  javascript_include_tag :defaults
  javascript_include_tag 'anotherscript.js'
  yield(:head)
end

Answer 2

In your controller:

def my_action
  render :layout => false
end

Answer 3

在控制器中调用render :action => "foo", :layout => false将完全跳过您的布局。
