I used this tutorial to implement nested forms with cocoon gem just few hours ago. You might find it useful. [this video] To get a strong understanding of how to create a nested form you should also see this video on how to do it without a gem. [LINK]

If you want to create nested models on the same page. i.e. milages within trip page using accepts_nested_attributes_for, You can use cocoon gem. [LINK] Drifting Ruby has a video that shows the process in detail that is easy to follow. [this video] You can do it manually as well but it will require a little bit more work. With cocoon you will do have a Driver Controller and Trip controller but you don't need a Milage controller since it is handled with nested_attributes via Trip Controller. If you want to do it manually, you will need a bit of JavaScript. You can follow Ryan Bates RailsCast on this topic. railscasts.com/episodes/196-nested-model-form-revised
