A last question, is there a way to define the join in the Section
mapper so that it would be possible to get a section's keywords by
just doing section.keywords?
mapper(Item, item_table, properties = {'keywords': relation(Keyword,
secondary=itemkeyword_table, backref='items')})
mapper(Keyword, keyword_table)
mapper(Section, section_table, properties = {'items': relation(Item,
backref='section'), 'keywords':relation(?express the join here)})
Thanks.
