Imp.model

model(class_: str) -> DefaultMeta

---

Returns the SQLAlchemy model class for the given class name that was imported using Imp.import_models or Blueprint.import_models.

This method has convenience for being able to omit the need to import the model class from the file it was defined in. However, it is not compatible with IDE type hinting.

For example:

from app.models.boats import Boats
from app.models.cars import Cars

Can be replaced with:

from app import imp

Boats = imp.model("Boats")
Cars = imp.model("Cars")

Or used directly:

from app import imp

all_boats = imp.model("Boats").select_all()

file: models/boats.py

from app import db


class Boats(db.Model):
    name = db.Column(db.String())

    @classmethod
    def select_all(cls):
        return db.session.execute(
            db.select(cls)
        ).scalars().all()
