问题 I am using Mezzanine (Django 1.10) so I can't see a " db.sqlite3 " I searched similar questions as mine and most of the solutions provided were not effective.

As it is possible that we require to re-generate the models from db due to changes in the schema, we have created alternative proxy models for each of those models to decouple the part that we manage from what we don't. Below you can see an example based on our current layout. The example

问题 I have trouble with django model migrations. I have some models in my app, and I already have some data inside.

Django - no such table exception

由 雨燕双飞 提交于 2019-11-30 09:18:57
In Django, I've added some models into models.py . After manage.py makemigrations , manage.py migrate raised this exception: django.db.utils.OperationalError: no such table: auth_test_usertranslatorprofile So I've removed all old migrations and run makemigrations and migrate again which seemed to work. Unfortunately, I've noticed that it didn't helped because when I try to click on User customer profiles of User translator profiles it raises exception: Environment: Request Method: GET Request URL: http://127.0.0.1:8000/admin/auth_test/usertranslatorprofile/ Django Version: 1.8.7 Python Version
