I've done many many-to-one relationships with SQLAlchemy, but there
must be something obvious I'm doing wrong here:
class Directory(Base):
__tablename__ = "directories"
id = Column(Integer, primary_key=True)
name = Column(String, unique=True)
subdirs = relation('Directory', backref="parentdir")
parent_id = Column(Integer, ForeignKey('directories.id'))
def __str__(self):
return "Dir: %s" % (self.name)
"Base" is standard declarative Base.
The odd behavior that I'm seeing is that on a newly created Directory
instance, both subdirs and parentdir are lists when I would expect
parentdir to just be null or a Directory.
This is using SQLAlchemy 0.5.2.
I do hope there's something obvious that I missed...
Thanks,
Kevin
