Andrew's given you the answer - it's just not clear that you've
understood what the answer is.

There are two ways to set a password on a user object:

* Use the set_password() method on the user object.

* Set the underlying password attribute directly.

The set_password() method is just applying the password hashing logic
and then saving the password field directly. If you want to set the
hashed value -- or set an "unusable" value -- directly, you can do the
same thing:

>>> from django.contrib.auth.models import User, UNUSABLE_PASSWORD
>>> user = User.objects.get(username='frank')
>>> user.password
u'sha1$911ee$25e954dc93f920c134ebaa067da7827922e474a6'
>>> user.has_usable_password()
True
>>> user.set_password('foo')
>>> user.password
'sha1$7h9Fpv6nLJt4$99f05f9b65569b617f32a448431736108e83be36'
>>> user.has_usable_password()
True
>>> user.password = UNUSABLE_PASSWORD
>>> user.save()
>>> user.password
'!'
>>> user.has_usable_password()
False
