I have a problem when I want to add several Count, the result is
incomprehensible.
individual:
{{{
User.objects.annotate(create=Count("event_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("eventlang_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("people_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("peoplelang_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("picture_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("picturelang_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("tag_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("taglang_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("translate_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 211}]>
User.objects.annotate(create=Count("translatelang_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 422}]>
User.objects.annotate(create=Count("video_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
User.objects.annotate(create=Count("videolang_creator")).values("username",
"create")
<QuerySet [{'username': 'rgermain', 'create': 0}]>
}}}
so the total is 633
(422 + 211 + 0 * 10) = 633
I would like to do it in one line so :
{{{
User.objects.annotate(create=
Count("event_creator") +
Count("eventlang_creator") +
Count("people_creator") +
Count("peoplelang_creator") +
Count("picture_creator") +
Count("picturelang_creator") +
Count("tag_creator") +
Count("taglang_creator") +
Count("translate_creator") +
Count("translatelang_creator") +
Count("video_creator") +
Count("videolang_creator")
).values("username", "create")
<QuerySet [{'username': 'rgermain', 'create': 178084}]>
}}}
total is 178084, same with aggregate.
i use sqlite3.
