Maybe (although there are some issues with the order of the arguments
in your __init__), but it's unnecessary. if you're using a ModelForm
to edit an existing instance, you should pass it in when you
instantiate the form.
bookObj = whatever
bookForm = BookForm(instance=bookObj)
And that way, when you save the form, it will save the changes to the
instance, rather than creating a new one.
