Is it likely that this construct:
@event.listens_for(Column, "before_parent_attach")
def attach(target, cls):
# cls is the table obj, not the declarative class
target.name = "%s%s" % (cls.name[0:4], target.name)
is interfering with Alembic??
I'm getting this stack trace and it changes if I disable the event listener
above.
I don't actually have any columns named "cat_cat_sit_id" so it looks like
that prefix is being double attached???
Thanks for any suggestions to fix this.
