Answer 1

Based on the exception models points to the models submodule of the django.db module, but there is no Book defined in that module.

Likely the Book originates from elsewhere, from an appname.models module.

You thus import this with:

from appname.models import Book

# …

def viewBooks(request):
    # …
    #        ↓ no models.
    books = Book.objects.all()
    # …
