问题
Can someone give a detailed explanation on how to fix the ERROR: no such table: main.auth_user__old
It arises in my Django application when I am trying to add data to my registered models.
回答1:
It's a compatibility issue between latest SQLite and Django. See here: Django - No such table: main.auth_user__old

I have solved this issue using below :
1) Delete the db.sqlit3
2) app's directory delete everything in pycache
3) manage.py makemigrations, manage.py migrate, manage.py createsuperuser and then manage.py runserver.

You probably haven't run the migrations. Until you run migrations, no tables are created. Hence the error. See https://docs.djangoproject.com/en/2.1/topics/migrations/#workflow
After you've registered your models, go to your git bash or powershell. Make sure you are in your project directory. Then run these commands :
python manage.py makemigrations
And then
python manage.py migrate
These commands will create tables for you and then you can add data to them.
