I have a *models.py* that contains 10 classes. And I am trying to move all classes out of that file and put each class into its own file under a models package.
I am using the alternative(at bottom of page) method mentioned here<https://docs.pylonsproject.org/projects/pyramid_cookbook/en/latest/database/sqlalchemy.html#importing-all-sqlalchemy-models>, but I don't know how it works for initialise db script as it is using *config.scan()* However, when i ran *bin/initialize_bug_db development.in *to initialise the database, it threw such as : sqlalchemy.exc.InvalidRequestError: When initializing mapper Mapper|User|users, expression 'TopicUser' failed to locate a name ("name 'TopicUser' is not defined"). If this is a class name, consider adding this relationship() to the <class 'bug.models.user.User'> class after both dependent classes have been defined. which was caused by something like *topics = relationship('TopicUser', backref="user", lazy='dynamic')* and sqlalchemy.exc.NoReferencedTableError: Foreign key associated with column 'notifications.topic_id' could not find table 'topics' with which to generate a foreign key to target column 'id' which was caused by something like *topic_id=Column(Integer, ForeignKey('topics.id'))* I am wondering how you guys organise the model files. Maybe there is a better way? Thanks. -- You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
