I’m sorry if question title is confusing or not clear but i didn’t have a better way of writting it.
I have a django app root, in models.py i created a model Post containing 3 manytomany fields ; File, Video and Picture and some other fields and while trying to populate the model in Django Admin or even to view any of the created Posts i get this error message django.db.utils.OperationalError: no such table: root_post_Picture. I already ran python manage.py sqlmigrate root 0001_initial and saw no table with such name and it’s not surprising since root_post_Picture corresponds to none of my models . I think it is related to the manaytomanyfields i created since the name root_post_Picture seems to be a combination of the tables root_post and root_picture from my database.
