How to overcome ModelForm has no model class specified error?

Question

Django

I wanted to create a form for editing personal data.

# Form code forms.py

from django import forms
from .models import AdvUser
class ChangeUserInfoForm (forms.ModelForm):
    email = forms.EmailField(required=True,
    label='Адрес электронной почты')
class Meta:
    model = AdvUser
    fields = ('username', 'email', 'first_name', 'last_name',
'send_messages')

The browser has this error:
