sqlalchemy and auto increments with postgresql

Question

I created a table with a primary key and a sequence but via the debug ad later looking at the table design, the sequence isn\'t applied, just created.

Answer 1

I ran into a similar issue with composite multi-column primary keys. The SERIAL is only implicitly applied to a single column primary key. However, this behaviour can be controlled via the autoincrement argument (defaults to "auto"):

id = Column(Integer, primary_key=True, autoincrement=True)
