SQLAlchemy with type hints

[gontajones]

Just for future reference, what I decided to do was this:

models.py

from typing import Type, Union

TableTypes = Union[Type['M1'], Type['M2'], ..., Type['M20']]


class M1(db.Model):
    ...
class M2(db.Model):
    ...
...
class M20(db.Model):
    ...

Then wherever you need type hints you can use it like:

import models as m
 
def func(table: m.TableTypes) -> bool
    ...
    return True

Now it's more clean and mypy is not screaming anymore! =)
