there's a comma somewhere. The code you have sent is incomplete. There
is no mapping "Version" for example.

Hello everyone,
I`m getting an error when creating a new instance of my model
`Type`. I have a many-to-many relationship between Type and Maker.
Code:

type_maker =db.Table('type_maker', db.metadata,
db.Column('type_id',db.Integer,db.ForeignKey('type.id
<http://type.id>')),
db.Column('maker_id',db.Integer,db.ForeignKey('maker.id
<http://maker.id>')))
classType(db.Model):"""VehicleType """__tablename__ ='type'id
=db.Column(db.Integer,primary_key=True) name

=db.relationship('Maker',secondary='type_maker',backref=db.backref('type'))def__repr__(self):return'<Type
#{}: {}>'.format(self.id,self.name)
classMaker(db.Model):"""VehicleMaker """__tablename__

type_ =Type(name='Car')

Error:

What is wrong with the code?
Thanks in advance!
