In the exemple 10.9, you create a @property success_msg and overwrite the form_valid method, so when the form is valid, the success_msg is pushed to the Django messages. This Mixin already exist in the contrib.messages app. Link to the documentation.

Yeah, that was added thanks to an earlier edition of the book (1.5 or 1.6, I can't remember). However, the simplicity of the example is enough that we aren't going to change our example.

Maybe in the next edition, we'll put in a note explaining it.
