Here’s the scenario… there are a lot of models in use in this one
controller, so I want to separate responsibility for remote calls into
different controllers.
some_controller has a view with a list of Foo objects.
some_controller has a form to create a new Foo object.
some_controller has an RJS template for the add_foo action to update its
view.
foo_ajax_controller has an add_foo action.
Is there a way that some_controller can invoke
foo_ajax_controller#add_foo, and have it render some_controller’s
‘add_foo.rjs’?
