How to fix an error with access?

Question

MySQL

In a flask in the main2 file through SQLAlchemy, I created several tables. Then I go to python main2.py shell.
I write commands there:

from main2 import db
db.create_all()

and after the last one I get an error

sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (1698, "Access denied for user 'root'@'localhost'")
(Background on this error at: http://sqlalche.me/e/13/e3q8).

how to solve the problem?

Answer 1

The problem is that in the settings where you specified the root database user, something is wrong. Check the username and password for it, which you pass in the code.
