Add attribute to admin model Django - django

Question

I'm trying to add an attribute to my user admin model, but it doesn't work,
here is what I succeded to do (I want to add inactivity field):
from django.contrib import admin
from .models import User
class usersAdmin(admin.ModelAdmin):
list_display = ('username', 'first_name', 'last_name', 'inactivity')
admin.site.register(User, usersAdmin)
Here is my model code:
class User(models.Model):
username = models.TextField(max_length=140, default='uid', primary_key=True)
first_name = models.TextField(max_length=140, default='cn')
last_name = models.TextField(max_length=140, default='givenName')
inactivity = models.IntegerField(default=500)
def _str_(self):
return self
The error occurs when I'm trying to access to my added field from my views:
class MyTokenObtainPairSerializer(TokenObtainPairSerializer):
def validate(self, attrs):
data = super().validate(attrs)
data['username'] = self.user.username
data['first_name'] = self.user.first_name
data['last_name'] = self.user.last_name
data['inactivity'] = self.user.inactivity
print(self.user)
return data
the error says:

PS: I'm using LDAP auth backend in setting.py I have:
import ldap

AUTH_LDAP_GROUP_SEARCH = LDAPSearch('ou=groups,dc=syneika,dc=com',ldap.SCOPE_SUBTREE, '(objectClass=top)')
AUTH_LDAP_GROUP_TYPE = PosixGroupType(name_attr="cn")
AUTH_LDAP_MIRROR_GROUPS = True
# Populate the Django user from the LDAP directory.

Answer 1

Please go into your root directory and delete all migrations from the root directory leaving only init file then go back into your command console and apply the migrations before you sync it to your database with migrate. Your from problem seems to come from the --fake migrate as it does not actually sync it to the databased.

I figured out that in my view (TokenView) I'm referencing to the Auth user and not the User Model in my models.
So to add another attributes to the Authenticating user (provided by Django by default), I must associate the Auth user to another model and add the attributes I want, I found it here : Django Profiles
from django.db import models
from django.contrib.auth.models import User
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
activity = models.IntegerField(default=500)
def _str_(self):
return self
