Upgrading

To v2.0.0

The logic that sets a Model class’ __table_args__ and __mapper_args__ (unless overridden in subclass) has been modified. A model’s __local_table_args__ and __local_mapper_args__ are now merged with __global_table_args__ and __global_mapper_args__ from all classes in the class’s mro(). A __{global,local}_{table,mapper}_args__ may be a callable or classmethod, in which case it is evaluated on the class whose __{table,mapper}_args__ is being set.

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()
