I just tried updating from 0.9.9 to 1.0.2 and noticed that this code

def _before_create(target, connection, **kw):
schemas = {table.schema for table in kw['tables']}
for schema in schemas:
CreateSchema(schema).execute_if(callable_=_should_create_schema).execute(connection)
listen(db.Model.metadata, 'before_create', _before_create)
Is this change intentional? I couldn't find anything about it in the
1.0 changelog.
OK, I think I should change this back because that was not
intentional, so it's a regression, and I've added
https://bitbucket.org/zzzeek/sqlalchemy/issue/3391/tables-collection-passed-to-before-after.
Though I looked at the docstring and it does give me some room to just
make changes:
additional keyword arguments relevant to the event. The contents of
this dictionary may vary across releases, and include the list of
tables being generated for a metadata-level event, the checkfirst
flag, and other elements used by internal events.
But the tables list here is actually there just for the purpose of
end-user event listening so that should probably be maintained as it was.
that is now fixed in
https://bitbucket.org/zzzeek/sqlalchemy/commits/e25ef01fbb70
