python - Auto-populating created_by field with Django admin site

Question

I want to use the Django admin interface for a very simple web application but I can't get around a problem that should not be that hard to resolve ..

Consider the following:

class Contact(models.Model):
    name = models.CharField(max_length=250, blank=False)
    created_by = models.ForeignKey(User, blank=False)

I can't find a way to auto-populate the created_by field and make the Django admin aware of it. Most of the method I've seen implies overloading the Object's save method and pass it the request user. They all requires to build your custom views and/or forms.

Optimally the form to create new contacts in the admin site should not show the created_by field (which is quite easy) and auto-populate it with the current user (which seems harder than it should).

Involves implementing save methods on your ModelAdmin objects.
