class MyModel(models.Model):
...
def __init__(self, user=None, *args, **kwargs):
super(MyModel, self).__init__(*args, **kwargs)
self.user = user
or:
class MyModel(models.Model):
...
def setUser(self, user=None):
self.user = user
Call setUser before you call any method that requires the user. If user is
None, you can raise an error in your model. Though it's best to do perm
checking in the view/templates or a form, though with the form you're going to
be passing around request.user also, but passing it part of the __init__() is
normal with forms.
please note this for models:
http://docs.djangoproject.com/en/dev/topics/db/models/#field-name-hiding-is-
not-permitted
Also, you might want to research the admin source to see how it handles the
user and permission model.
