Django: How to get current user in admin forms

Question

In Django\'s ModelAdmin I need to display forms customized according to the permissions an user has. Is there a way of getting the current user object into the form class, s

I think I found a solution that works for me: To create a ModelForm Django uses the admin's formfield_for_db_field-method as a callback.
So I have overwritten this method in my admin and pass the current user object as an attribute with every field (which is probably not the most efficient but appears cleaner to me than using threadlocals:

    def formfield_for_dbfield(self, db_field, **kwargs):
        field = super(MyAdmin, self).formfield_for_dbfield(db_field, **kwargs)
        field.user = kwargs.get('request', None).user
        return field

Now I can access the current user object in the forms __init__ with something like:

    current_user=self.fields['fieldname'].user
