I currently do it like this:
class DocTable(Table):
""" Extends Table by adding a description attribute """
def __init__(self, name, metadata, **kwargs):
""" Extract some parameters and call parent """
description = kwargs.pop('description', None)
self.description = description
super(DocTable, self).__init__(name, metadata, **kwargs)
class DocColumn(Column):
""" Extends Column by adding a description attribute """
def __init__(self, name, type_, *args, **kwargs):
""" Extract some parameters and call parent """
description = kwargs.pop('description', None)
self.description = description
super(DocColumn, self).__init__(name, type_, *args, **kwargs)
And then I use "DocTable" / "DocColumn" instead of Table/Column.
Regards,
Hermann
