I have a bunch of Mixins for SQL alchemy objects for doing standard stuff
that I use in multiple projects and this all works well by using
@declared_attr like this:
class CategoryMixin(object):
@declared_attr
def title(self):
""" Unique title for the category """
return sa.Column(sa.Unicode(30), nullable=False, unique=True)
The use of this class would be like this:
Base = declarative_base()
class Category(CategoryMixin, Base):
pass
but I now want to make some many to many relationships so I need Table()
which requires me to pass it a meta data. Is there a way to do this in the
same way as the declared attributes?
