Circular Dependency In Models With Sqlalchemy

I'm creating a webapp which uses SQLAlchemy to access the database. I'm getting stuck with two models which are referencing to each other and ending up in an circular import which

Solution 1:

In this specific case, there is no need to import EmailModel at all. Alter keymodel.py to remove the import:

from pyncacoreapi.server.modelsimportApplicationModel

SQLAlchemy postpones resolving references given as strings until the last possible moment anyway, so it doesn't matter here that EmailModel is defined yet or not. You are referring to it in the email relationship via a string.
