def by_user_name(cls, username):
return cls.query.filter_by(user_name=username).first()
I used Sqlalchemy to replace SQLObject as my default ORM in this
application, and enabled user identity as well.
But when to start this application by using "python.." statements, it
threw an error that "cls class can't have query such method"
What's wrong with it? The code above is created in the build-in
process of create a new project.
Thanks in advance.
