Django 1.6在反向字段和條件下注釋

Question

我想基於遠程模型的字段在遠程模型（遍歷2模型關係）上進行註釋，只有當它是假的。這可能嗎？

foo = CommunityProfile.objects.annotate(answered_count=Count('threadvault__unanswered'=False)) 

Answer 1

先過濾查詢集，然後註釋。

profiles = CommunityProfile.objects.filter(
    threadvault__unanswered=False 
).annotate(
    answered_count=Count('threadvault') 
)
