I've tried to follow "Specifying Alternate Join Conditions to
relation()" recipe from the docs and got an error about invalid kwarg:
File "/usr/lib/python2.5/site-packages/SQLAlchemy-0.4.5-py2.5.egg/
sqlalchemy/orm/__init__.py", line 566, in mapper
return Mapper(class_, local_table, *args, **params)
TypeError: __init__() got an unexpected keyword argument
'foreign_keys'
Here is the offending code:
mapper(WordpressPost, wp_posts_tbl, properties={
'categories': relation(WordpressTaxonomy, primaryjoin=
and_(wp_terms_taxonomy_tbl.c.taxonomy=='category',
wp_term_relationships_tbl.c.term_taxonomy_id==wp_terms_taxonomy_tbl.c.term_taxonomy_id)),
}, foreign_keys=[wp_terms_taxonomy_tbl.c.term_taxonomy_id])
