Hi Chrys,

First, we're not using Django's admin application here to add authors or books. The idea here is that we want to allow client users to add/remove books using our UI, that's why I haven't added Book and Author instances in admin.py file. You can easily add them if you need to.

Second, this article provides the code for adding/removing books only since I wanted to keep the code simple. Certainly you can go one step further and implement the functionality that adds/removes authors as well, similarly like we're doing with books.

I hope that this answers your questions.

Cheers,

Fatime
