How can I use UUIDs in SQLAlchemy?

Question

Is there a way to define a column (primary key) as a UUID in SQLAlchemy if using PostgreSQL (Postgres)?

Answer 1

If you are happy with a 'String' column having UUID value, here goes a simple solution:

def generate_uuid():
    return str(uuid.uuid4())

class MyTable(Base):
    __tablename__ = 'my_table'

    uuid = Column(String, name="uuid", primary_key=True, default=generate_uuid)
