Hi,
Sorry if this is a FAQ, but is it possible to define a relationship
and its column all at once. e.g. instead of:
type_id = db.Column(db.Integer, db.ForeignKey('linktype.id'))
type = db.relationship('LinkType')
Something like:
type = db.relationship('LinkType', colname='type_id')
In fact, it'd be good for the colname to default to "xxx_id" -
although allow overriding.
This certainly was possible with Elixir.
this would be a many_to_one() macro. Two examples of this are at:

the above is a modernized improvement on an older example:
