Usage¶

You can check the feature status with continuum_is_enabled():

app = config.get_app()

if not app.continuum_is_enabled():
    print("Oh no!  Continuum is not enabled.")

The rest of this will assume the feature is enabled.

Built-In Models¶

The following built-in models are versioned. So, when records are added / modified / removed via the ORM, new version records are automatically created for each of these:

Permission
Person
Role
User
UserRole

Object Versions¶

A versioned model works normally but also has a versions attribute, which reflects the list of version records:

user = session.query(model.User).first()

for version in user.versions:
    print(version)
