Question

我正在为简单的问答论坛开发网站。我想获得答案。

models.py

class Answer(models.Model):
    ans = models.TextField()
    img = models.CharField(max_length=100)
    created_by = models.ForeignKey(User, related_name='answer')
    created_on = models.DateTimeField(auto_now_add=True)
    ques = models.ForeignKey(Question, related_name='answer')
    def __str__(self):
        return self.ans

class Upvote(models.Model):
    upvote = models.BooleanField(default=False)
    upvote_by = models.ForeignKey(User, related_name='upvote')
    upvoted_on = models.DateTimeField(auto_now_add=True)
    #ques = models.ForeignKey(Question, related_name='upvote')
    ans = models.ForeignKey(Answer, related_name='upvote')
    def __str__(self):
        return self.upvote_by

views.py

我可以获得如下答案的赞成票

 answer = get_object_or_404(Answer, pk=1)
 upvotes = Upvote.objects.filter(ans=answer)

如何从答案对象中获取回报？如果我错了，请纠正我。如下所示，

answer.upvote_set

提前致谢!!

Answer 1

鉴于您在模型中显示的此字段：

A       Event 1 Event 2 Event 3
B       Group 1 Group 2

你可以访问这样的答案的赞成票

class Upvote(models.Model):
    # ... other code ...
    ans = models.ForeignKey(Answer, related_name='upvote')
    # ... other code ...

如果您将字段定义更改为此（删除answer_instance.upvote.all()）：

related_name

您应该能够使用您询问的代码：

ans = models.ForeignKey(Answer)

如何在Django中获得答案？
