>>> qs = Model.objects.extra(where=['foo>%s'], params=).annotate(count=Count('bar')).filter(bar=99) >>> qs.query.as_sql() ('SELECT `site_publication`.`id`, ..., FROM ... WHERE foo > %s GROUP BY ... HAVING bar > %s', (99, 2))
As you can see, the parameters (99 and 2) are in the wrong order. "foo", the first filter, should be evaluated against 2, and bar, the second one, against 99.
If "bar" is not an aggregate, it works, because apparently the filter would be placed in the WHERE clause *before* the "extra()" where.
Using rev. 10743.
