not a bug, ForeignKey() objects are passed to Column as positional arguments and they are taken in here: https://github.com/sqlalchemy/sqlalchemy/blob/master/lib/sqlalchemy/sql/schema.py#L1335 > > This kind of contradicts the column.,copy method which writes constraints and > foreign_keys into kwargs that are passed to the constructor (lines 1492) I don't see that, the constraints are written into a list called args, no keywords, which is then passed along where it is accepted by line 1335 above > The duplicated column objects in my case lack the foreign_keys ah, where you say "my case", that's the important part to share. Bugs are illustrated by showing an example of code, what you expect it to do, and what it's not doing.
