4.4 Additional Layout Options
You can specify layout options at the controller class level if you want to reuse layouts for multiple actions.
class EventController < ActionController::Base
layout "events", only: [:index, :new]
layout "global", except: [:index, :new]
end
The layout method can accept either a String Symbol, or boolean, with a hash of arguments after:
- String Determines the template name to use.
- Symbol Call the method with this name, which is expected to return a string with a template name.
- true Raises an argument error.
- false Do not use a layout.
The optional arguments are either :only or :except and expect an array of action names that should or should not apply to the layout being specified.
