Upgrading

To v1.0.0

The @classproperty decorator has been eliminated and replaced with @classmethod in v1.0.0. This means that the previous alchy.model.ModelBase class properties must now be accessed via method calls:

• alchy.model.ModelBase.session()
• alchy.model.ModelBase.primary_key()
• alchy.model.ModelBase.primary_keys()
• alchy.model.ModelBase.primary_attrs()
• alchy.model.ModelBase.attrs()
• alchy.model.ModelBase.descriptors()
• alchy.model.ModelBase.relationships()
• alchy.model.ModelBase.column_attrs()
• alchy.model.ModelBase.columns()
