Hi I have yet another problem with tgext.pluggable.
I Tried putting this model definition in my plugin
tag_article= Table('tag_article', metadata,
Column('tag_id', Integer, ForeignKey('tag.id'), primary_key=True),
Column('article_id', Integer, ForeignKey('article.id'),
primary_key=True))
class Tag(DeclarativeBase):
__tablename__ = 'tag'
id = Column(Integer, autoincrement=True, primary_key=True)
text= Column(Unicode(200))
class Article(DeclarativeBase):
__tablename__ = 'article'
id = Column(Integer, autoincrement=True, primary_key=True)
text= Column(Unicode(2000) )
tags = relation(Tag, secondary=tag_article, backref='articles')
but whenever I start TG:
sqlalchemy.exc.ArgumentError: Could not determine join condition between
parent/child tables on relationship Article.tags. Specify a 'primaryjoin'
expression. If 'secondary' is present, 'secondaryjoin' is needed as well.
I tried to move this model definition inside the main project and it works
normally.
