Selecting specific users

I have a a model that stores users:

class SubItem(models.Model):
    created = models.DateTimeField(default=datetime.now)
    created_by = models.ForeignKey(User)

I have a group in the auth admin section c开发者_StackOverflow中文版alled 'advisors'. How do I only show the advisors in the pulldown that django creates. (I have a feeling I have to override the init in forms.py)

You are looking for the limit_choices_to parameter.

Example:

class SubItem(models.Model):
    created = models.DateTimeField(default=datetime.now)
    created_by = models.ForeignKey(User,
        limit_choices_to={'group': 'advisors'})

I found out from this link that only selecting users in a set group needs to be enforced at the form level

class SubItemForm(ModelForm):

    def __init__(self,user,*args,**kwargs):
        super(SubItemForm, self).__init__(*args, **kwargs)
        self.fields['advisor'].queryset = User.objects.filter(groups__name='advisor')

I hope this helps someone
