I have this query: myDevices=Device.objects.filter(group=groups) where groups is a list. What I want is get all the devices that is in one of the groups in the list groups. If group only has one element, everything goes as expected. But if groups has more than one element, which is often the case, I get this error:
(1242, 'Subquery returns more than 1 row') I'm using mySql as the database engine. Do I have to iterate over groups and make the query for each element, or is there a smarter way to get this done? Thanks.
