Question

I have made a group “general” from admin panel.

Now I want when a new user register to my app it will by default assign to this group and user_id and group_id stored in intermediate table of auth_user and auth_group.

Actually I have tried this myself and getting errors.

EDIT

def signup(request, template="accounts/account_signup.html"):
    """
    Signup form.
    """
    profile_form = get_profile_form()
    form = profile_form(request.POST or None)
    #return render_to_response('test.html',{'q':email},context_instance=RequestContext(request))
    if request.method == "POST" and form.is_valid():
        new_user = form.save()
    group_id=Group.objects.get(id=1)
    group_id.groups.add(new_user)
    #group = User_Groups(user=new _user,group=1)
    #group.save()
    last_inserted_id = User.objects.order_by('-id')[0]
    value_email = last_inserted_id.email
    ...............

Error

‘Group’ object has no attribute ‘groups’

Answer 1

This, to begin with, will help you understand the error you’re getting

group_id = Group.objects.get(id=1)

Here, group_id becomes an instance of the model Group.
Group and its instances have attributes name, and permissions.

group_id.groups.add(new_user)

Is nonsense. groups is an attribute of User and not Group.
Replace group_id with new_user :

new_user.groups.add(group_id)

This will add group_id (which should be named group instead) to the list of groups new_user is member of.
