You have to convert the ObjectId's to strings and that means iterating the queryset.
Why do you need them to be strings in the $in query - its more efficient to store ObjectIds.
문제
I am executing a query with mongoengine. As a result I want to get a list of ids to continue working with them.
When I use .scalar("id")
I get a queryset with objects ids
Test.objects.filter(is_deleted=False).scalar("id") --> [ObjectId(kasdfji93jiasdkfj),....]
For my following raw query i need this Format [kasdfji93jiasdkfj,....]
{ field: { $in: [kasdfji93jiasdkfj,....] } }
Does anybody know an approch without iterating through the queryset to build this list?
Thanks a lot!
