我正在做一个项目，该项目要求用户尽可能使用 django rest_framework 提供反馈但我在这样做时遇到了一些困难下面是我的代码 sn-p & err msg

##模式文件

class Review(models.Model):
    school = models.ForeignKey(
        Profile, on_delete=models.CASCADE, related_name='review')
    name = models.CharField(max_length=250, blank=True, null=True)
    reviewer_email = models.EmailField()
    rating = models.CharField(
        max_length=250, blank=True, null=True)

    review = models.TextField()

##serializer 文件


class ReviewSerializer(serializers.ModelSerializer):
    class Meta:
        model = Review
        fields = ('name',  'review', 'id', 'reviewer_email', 'rating')
 
    def perform_create(self, serializer):
        id = self.request
        print(self.request.user.profile)
        serializer.save(school=self.request.user.profile.school_id)

##apiView

class ReviewAPIView(generics.CreateAPIView):
    serializer_class = ReviewSerializer
    permissions = [permissions.AllowAny]
    queryset = Review.objects.all()

谁能帮忙

【问题讨论】：

标签： django django-rest-framework django-serializer

【解决方案1】：

您没有共享请求正文。我的猜测（从错误中）是你没有指定它应该与之相关的学校对象的 id

【讨论】：

【解决方案2】：

您应该限制非授权用户的访问。否则，self.request.user 可能是一个 AnonymousUser 对象，它没有配置文件关系。

permissions = [permissions.IsAuthenticated]
