Migration don't work

[sebasti...@gmail.com]

I get on migration following error:

Traceback (most recent call last):

Now i grep after grep -r "0002_reset_table_names" . and nothing are find in my project dir or in venv. I look in django_migrations table and there aren't such a entity. I have feeling that is cached entry because in history i have such a venv with this file but i delete complete venv and load right venv where this file don't exists

it seems to be that you have an app in the project named order and it should have a migration file named 0008_auto_20190301_1035.
0008_auto_20190301_1035 seems to be absent for some reasons.

You should check and confirm that.
