def clear_respond_to
  self.mimes_for_respond_to = ActiveSupport::OrderedHash.new
end

#respond_to(*mimes) ⇒ Object

Defines mimes that are rendered by default when invoking respond_with.

Examples:

respond_to :html, :xml, :json

All actions on your controller will respond to :html, :xml and :json.

But if you want to specify it based on your actions, you can use only and except:

respond_to :html
respond_to :xml, :json, :except => [ :edit ]

The definition above explicits that all actions respond to :html. And all actions except :edit respond to :xml and :json.

You can specify also only parameters:

respond_to :rjs, :only => :create
