| # Inline Formsets ############################################################

| 
 | |
| We can also create a formset that is tied to a parent model. This is how the

| Now that we've added a book to Charles Baudelaire, let's try adding another
 | |
| one. This time though, an edit form will be available for every existing

| The save_as_new parameter lets you re-associate the data to a new instance.
