WTForms / SQLAlchemy field validation

Question

Is there a quick way to use my SQLAlchemy model to do length validation / instantiate a field for a CRUD form I'm using to interact with the database? I feel like I'm repeating the lengths alot like so...

class MyModel(db.Model):
    ...
    SomeField = db.Column(db.String(30))

with a matching form:

class MyForm(FlaskForm):
    MyFormField = StringField('Some Field', validators=[Length(30)])

没关系，我发现了WTForms-Alchemy https://wtforms-alchemy.readthedocs.io/en/latest/
