 Generic class based views allow for fast development of basic views. Today
 I ran into a situation where I had to set a `PasswordInput` on a form
 field. But the only solution I found was creating an actual `ModelForm`
 and specifying it as `form_class` on the view.

 I then created a patch that allows setting the widgets through the view:
