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.
