You have shared very little which means I will make some assumptions about
your specific implementation need. I see you have a Book model that has
total number of books. I imagine you want to *minus* or *add *to the total
number of books every time a book is borrowed or new books are added to the
system.
Depending on requirements, you could:
- Use what is called a calculated field in the model
- Calculate the remaining the number of books in the views whenever an
event occurs (one that affects the total of numbers of books), say a
student borrowing a book.
