列表正在工作，但在Django Rest Fram中的嵌套序列化程序中post不工作

Question

这是我的密码：

你知道吗型号.py你知道吗

class Kitchen(models.Model):
kitchen_name = models.CharField(max_length = 100)
state = models.CharField(max_length = 40, )
city = models.CharField(max_length = 40)

def __str__(self):
    return self.kitchen_name


class AssignAudit(models.Model):
kitchen = models.ForeignKey(Kitchen, on_delete = models.SET_NULL, null = True)
assigned_date = models.DateTimeField(default = timezone.now)
assigned_by = models.ForeignKey(User, on_delete = models.SET_NULL, null =  True, related_name = 'assigned_audits')

class KitchenAudit(models.Model):
assign_audit = models.ForeignKey(AssignAudit, on_delete = models.SET_NULL, null = True)
question = models.ForeignKey(Question, on_delete = models.SET_NULL, null = True)
total_images = models.IntegerField(null = True, blank = True)
marks_scored = models.IntegerField(null=True,blank=True)
comment = models.CharField(max_length = 300, null = True, blank = True)

你知道吗序列化程序.py你知道吗

class KitchenSerializer(serializers.ModelSerializer):
class Meta:
    model = Kitchen
    fields = '__all__'

class AssignAuditSerializer(serializers.ModelSerializer):
kitchen = KitchenSerializer()
class Meta:
    model = AssignAudit
    fields = '__all__'

def create(self, validated_data):
    assign_audit = AssignAudit.objects.create(**validated_data)        
    questions = Question.objects.all()
    for question in questions:
        kitchen_audit = KitchenAudit.objects.create(question=question,assign_audit=assign_audit)
        for images in range(question.no_of_images):
            KitchenAuditImage.objects.create(kitchen_audit=kitchen_audit)
    return assign_audit

你知道吗视图.py你知道吗

class AssignAuditSerializerListCreate(ListCreateAPIView):
serializer_class = AssignAuditSerializer
queryset = AssignAudit.objects.all()

    def list(self, request, *args, **kwargs):
    queryset = self.filter_queryset(self.get_queryset())
    page = self.paginate_queryset(queryset)
    if page is not None:
        serializer = self.get_serializer(page, many=True)
        return self.get_paginated_response(serializer.data)
    serializer = self.get_serializer(queryset, many=True)
    return Response({'audit_assign':serializer.data})

我想结合上面的两个表，使用django rest框架在一个API中显示它。GET方法很好用，但当我使用POST方法时，它意味着我必须提供厨房价值。你知道吗

{
    "kitchen": [
        "This field is required."
    ]
}

Answer 1

您已经设置了read_only = True，这就是为什么它在发布、放置或修补时忽略了kitchen。它是清晰的只读，所以你不能张贴到它。你知道吗

作为替代方法，您可以重写视图中的get\u serializer\u class（）函数来实现这一点。你知道吗

Answer 2

一种可能的解决方案是将kitchen设为只读。你知道吗

kitchen = KitchenSerializer(read_only=True)
