Is it possible to have a field in a Django model which does not get stored in the database.
For example:

class Book(models.Model):
    title = models.CharFie

    As long as you do not want the property to persist, I don't see why you can't create a property like you described. I actually do the same thing on certain models to determine which are editable.

    class Email(EntryObj):
        ts = models.DateTimeField(auto_now_add=True)
        body = models.TextField(blank=True)
        user = models.ForeignKey(User, blank=True, null=True)
        editable = False
        ...
    
    
    class Note(EntryObj):
        ts = models.DateTimeField(auto_now_add=True)
        note = models.TextField(blank=True)
        user = models.ForeignKey(User, blank=True, null=True)
        editable = True
