Thanks a lot! It works but I still have a problem. I want to make one query
to get the root directory, all its children and the filenames of Image

My directory model looks like this:

I have another problem related to this setup. I have a property defined on
the Image model:
@property
def filename(self):
return '{basename}.{extension}'.format(basename=self.basename, extension

Those are some great ideas. I will try them out. Thanks Michael!

I just came across a solution to this problem. Adding 'with_polymorphic':
'*' to __mapper_args__ on the Node model was enough.
class Node(db.Model):
id = db.Column(db.Integer, primary_key=True)
type = db.Column(db.String(20))
name = db.Column(db.String(30), nullable=False)
