我有两个型号
class Entry(models.Model):
properties = here
class ReadedEntries(models.Model):
entry = models.ForeignKey(Entry, on_delete=models.CASCADE)
user = models.ForeignKey(User, on_delete=models.CASCADE)
如何从用户那里获取无readed条目?
我试试:
not_looked_videos = Entry.objects.exclude(ReadedEntries.objects.filter(user=request.user))
但我明白了:
ValueError: need more than 0 values to unpack
答案 0 :(得分:1)
尝试使用isnull来设置所有空的ReadedEtries设置:
Entry.objects.filter(readedentries__isnull=True)
或者仅排除当前的readed条目: 用户
Entry.objects.exclude(readedentries__user=request.user))
答案 1 :(得分:1)
1,过滤~Q(id__in = ids)
其中ids = ReadedEntries.objects.filter(user = request.user).values_list('id',flat = True)
2.我仍在努力完成它......
