Pyramid: how to distribute the content of the models. py file to multiple files

The following file structure is used to change models. py to a package.

Copy codeThe Code is as follows:
Myapp
_ Init _. py
Scripts
_ Init _. py
Initialize_db.py
Models
_ Init _. py
Meta. py
Foo. py
Moo. py

The above meta. py defines a other model file sharing Base and DBSession in the code.

Copy codeThe Code is as follows:
Base = declarative_base ()
DBSession = scoped_session (sessionmaker (extension = ZopeTransactionExtension ))

Foo. py and moo. py are specific model definitions.
Foo. py and moo. py use the base defined in meta. py

To ensure that the defined model can be enabled in the program, introduce them in models/_ init _. py:

Copy codeThe Code is as follows:
From. meta import DBSession
From. foo import Foo
From. moo import Moo
