So basically my understanding is that the way to fix this is to run db.create_all() using the same instance of db that is being used to define the models. What I discovered is that the models (like User) are registered with the particular db object that is listed in the model's class definition (e.g. So when you run db.create_all() in _init_.py, it is checking the list of tables that it knows about and isn't finding any. The db object in _init_.py is a totally separate object from the db you are creating in models.py. I strongly suspect the problem here is that the instance of db that you are creating in _init_.py is unaware of the contents of models.py, including the User class. I just got done setting up a Flask app and I dealt with this kind of problem.

It would be appreciated and really great if anyone can help me because this problem is like killing me and already cost me two days, I feel really bad. I have researched similar problem on Github and Stackoverflow but none of the typical typo or error in old questions happens to me. I am fresh to flask and was trying to build a blog on my own, and I ran into an issue with SQLite operation error.
