Different time intervals creations
I have datetime objects for start_time and end_time. Both of these from user comes in 24 hours. for eg: 14:00hrs and 16:00hrs.

I need to keep a tally of both from_time and end_time here to create slots. Can anyone suggest some help? -

How to reflect changes on both One-To-Many-Relationship instances when updating one of them at once in Django?
I have two tables connected with a Foreignkey. I have a field in the main model, its value depends on the child instances. For example, if I have a Library model and a Book model, Book has Foriegnkey to Library. And we have a field in the Library model which is equal to the "total_price" of all the books in the library. How I can update that field "total_price" whenever I increase the quantity of a certain book or decrease it. Note that I have to save each instance separately in order to get the value right. I have the Books as a TabularInline inside Library, so I make the change to the quantity and save the changes, and then I have to press save one more time to change the "total_price" field. -
