I'm use sqlalchemy 0.6.4.
I have 2 classes: Question and Tag, they are many-to-many.
{{{
class Question(Base):
__tablename__ = "questions"
id = Column(Integer, primary_key=True)
deleted = Column(Boolean)
...
tags = relationship('Tag', secondary=r_questions_tags)
class Tag(Base):
__tablename__ = "tags"
id = Column(BigInteger, primary_key=True)
questions = relationship('Question', secondary=r_questions_tags)
}}}
So, tag.questions will get all the questions belong to a tag.
But now, since the Question has a deleted column, I hope to do like
this:
{{{
class Tag(Base):
...
# get non-deleted questions
questions = relationship('Question', secondary=r_questions_tags,
condition='Question.deleted==False')
# get deleted questions
deleted_questions = relationship('Question',
secondary=r_questions_tags,
condition='Question.deleted==True')
}}}
But unfortunately, there is no such condition parameter. What can I do
now?
