Instance Method Details

#set_default_flash(type, message) ⇒ Object

Sets the default flash message. This message can be overridden by passing in an HTTP parameter of the form “_flash” via POST or GET.

You can use this to easily have multiple forms post to the same create/edit/destroy actions but display different flash notices - without modifying the controller code at all.

By default, the flash types are notice when the database operation completes successfully and error when it fails.

def set_default_flash(type, message)
  flash[type] ||= (params[:_flash] && params[:_flash][type]) || message
end

#set_default_redirect(to, options = {}) ⇒ Object

Sets the default redirect (the argument passed to redirect_to). This message can be overridden by passing in an HTTP parameter of the form “_redirect_on” via POST or GET.

You can use this to easily have multiple forms post to the same create/edit/destroy actions but redirect to different URLs - without modifying the controller code at all.

By default, the redirect statuses are success when the database operation completes successfully and failure when it fails. Use the :status option to specify which status to run the redirect for. For example:

set_default_redirect "/posts", :status => :failure

This will run redirect_to params[:_redirect_on][:failure] if the parameter exists, or redirect_to "/posts" otherwise.
