configures a DataSet class.
The inner class Meta is used to configure a DataSet . The following are
acknowledged attributes:
- storable
- an object that should be used to store this DataSet. If omitted the
loader's style object will look for a storable object in its env,
using storable_name
- storable_name
- the name of the storable object that the loader should fetch from
its env to load this DataSet with. If omitted, the loader's style
object will try to guess the storable_name based on its env and the
name of the DataSet class
- primary_key
- this is a list of names that should be acknowledged as primary keys
in a DataSet. The default is simply ['id'].
