You can have an OneToOneField in the profile referencing Django's User model with `related_name='profile'`, so you can access information from there as `user.profile.birthday`. An useful link: https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html
About the admin interface changing the model, I guess you're somehow editing `models.py` files. Are you making the migrations, applying them to the database and reloading the server? If you're not persisting changes that way, how do you patch models in memory every startup and ensure database schema is compatible with your models? -- You received this message because you are subscribed to the Google Groups "Django users" group.
