Instance Method Details

#flex_scaffold(model_id, options = {}) ⇒ Object

Adds Flex REST actions to the controller. The options are the same as for ActionView::Scaffolding.scaffold, except that the :suffix option is not currently supported.

These are merely the same as a resource albeit a couple of mods
