我有一個神秘的問題，注釋沒有顯示在使用反向外鍵的查詢集上。使用 Django 2.2。楷模from django.contrib.gis.db import modelsclass Hexgrid_10km2(models.Model):    polygon = gismodels.MultiPolygonField(srid=4326)class Reply(models.Model):    user = models.ForeignKey(User, on_delete=models.CASCADE)    reply_date = models.DateTimeField()    ability = models.FloatField(default = 0)    hexgrid_10km2 = models.ForeignKey(Hexgrid_10km2, related_name='replies', on_delete=models.CASCADE, null=True, blank=True)問題我首先將 Hexgrid_10km2 過濾為僅包含回復的那些：most_recent = Reply.objects.filter(    reply_date=Subquery(        (Reply.objects            .filter(user=OuterRef('user'))            .values('user')            .annotate(most_recent=Max('reply_date'))            .values('reply_date')[:1]        )    ))hex_qs = Hexgrid_10km2.objects.filter(replies__in=most_recent)>>> hex_qs<QuerySet [<Hexgrid_10km2: Hexgrid_10km2 object (197028)>, <Hexgrid_10km2: Hexgrid_10km2 object (197028)>]>我檢查它們是否確實包含回復：>>> hex_qs.aggregate(Sum('replies__ability')){'replies__ability__sum': 2.0}現在謎...>>> hex_qs.annotate(avg_ability=Avg('replies__ability'))<QuerySet [<Hexgrid_10km2: Hexgrid_10km2 object (197028)>]>注釋在哪里？它與我用來構建模型的 geodjango 有關嗎？我感覺自己像個傻瓜。非常感謝您的幫助，因為我完全卡住了。
