Hi, Sorry for asking a new B question. I have following code in a module.py:
class Group(models.Model): ...... users = models.ManyToManyField(User, blank=True, null=True) ..... I can add user or delete user by calling Group.users.add(user) or Group.users.remove(user), but how can I check if the user has already in the database? Thank you. -j -- You received this message because you are subscribed to the Google Groups "Django users" group.
