In views.py, I want users who belong to a specific group to be True.

Hello! This is my first question.
I don't usually use English very much, so if something doesn't make sense to you, please ask for more details.

I'm currently trying to use django-rules to determine if a user belongs to a certain group or not.
but the superuser is successfully excluded in html, but in views.py, it is always True.

What is wrong with this?

#rules.py

import rules
from rules import has_perm


is_admin = rules.is_group_member( 'is_admin' )
is_aaa = rules.is_group_member( 'aaa' )

@rules.predicate
def is_aaa_group(user):
    return user.has_perm( 'is_aaa' )

# Permissions
rules.add_perm( 'is_admin', is_admin )
rules.add_perm( 'is_aaa', is_aaa )

# views.py

class BookListView( ListView ):

    model = Book
    template_name = 'index.html'

    def get( self, request, *args, **kwargs ):
        user = self.request.user

        print( is_aaa_group(user) )

        return super().get( request, *args, **kwargs )

# superuser
Reality -> True  ← orz
Ideal -> False
# aaa group
Reality -> True
Ideal -> True

In html, it works as expected. ↓

{% extends "base.html" %}
{% load static %}
{% load rules %}
{% has_perm 'is_admin' request.user as is_admin %}
{% has_perm 'is_aaa' request.user as is_aaa %}

{% block content %}


  {% if is_admin %}j

    <li>only superuser.</li>

  {% elif is_aaa %}

    <li>only aaa group.</li>

  {% endif %}


{% endblock %}

thank you.
