Changing password in Django Admin

Question

I recently created the admin.py based in the Django Project Document:

https://docs.djangoproject.com/en/dev/topics/auth/customizing/#django.contrib.auth.models

Answer 1

I added this method to my UserAdmin class:

def save_model(self, request, obj, form, change):
    # Override this to set the password to the value in the field if it's
    # changed.
    if obj.pk:
        orig_obj = models.User.objects.get(pk=obj.pk)
        if obj.password != orig_obj.password:
            obj.set_password(obj.password)
    else:
        obj.set_password(obj.password)
    obj.save()

You can the show the password field normally, but admins will only see the hashed password. If they alter it, the new value is then hashed and save.

This adds a single query to each time you save a user via the admin. It should generally not be an issue, since most systems don't have admins intensively editing users.
