SQLAlchemy no password supplied error

Question

This is probably a silly error but I cannot seem to find a satisfying solution.

When running db.create_all(), I got the following error.

Answer 1

URL pattern should be:

postgresql://user:password@localhost:5432/database_name

pip install psycopg2
the user should be postgres or any other user you have created and intend to use

similarly for mySql it would be:

mysql://user:pass@localhost:3306/database_name

pip install mysql-python
