Using the omniauth gem, I am forced to define a single route callback for succesful logins, regardless of the provider :
def auth_callback auth_data = request.env['omniauth.auth'] if auth_data.has_key('something') process_one(auth_data) else process_two(auth_data) end # No view is available here end def process_one # do something then render view for process_one return end def process_two # do something then render view for process_two return end How can I prevent the controller from returning to the auth_callback method and try to display the corresponding view (which does not exist) ? Treatment should be considered as complete once the process_one or process_two methods have returned.

redirect_to is not return Keep in mind that redirect_to does not cause the action to stop executing. It is not like calling return in a Ruby method.
By default, if you use the :plain option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the layout: true option and use the . text. erb extension for the layout file.
Rails Guides describes partials this way: Partial templates - usually just called "partials" - are another device for breaking the rendering process into more manageable chunks. With a partial, you can move the code for rendering a particular piece of a response to its own file.
Rendering is the ultimate goal of your Ruby on Rails application. You render a view, usually . html. erb files, which contain a mix of HMTL & Ruby code.
Why not specifically call render in those methods?
def process_one # do something then render view for process_one render :process_one and return end Rails should detect that you've already run it and not try to render again.
