Django - How to properly access reverse relationship ManyToManyField -

this models.py (i'm using default django user model well):

class userextended(models.model):     user = models.onetoonefield(user, related_name="userextended_set")     location = models.foreignkey(location)     follow = models.manytomanyfield(user, related_name="follow_set") 

now, access list of 'follow' users of particular user (users particular user following), i'd this:

a = user.objects.get(username='a') a.userextended_set.follow.count() 

my question is, how list of users whom particular user on 'follow' list of (i.e. following him)? tried this:

# assuming user 'a' on 'follow' list of 1 users (i.e. # assuming .get() return 1 user object). user.objects.get(username='a').follow_set.get().username 

but error saying

attributeerror: 'userextended' object has no attribute 'username' 

i think need:

user  # user userextended.objects.filter(follow=user)
