Question

我有一个像这样的serializerclass：

class EmployeeSerializer(serializers.ModelSerializer):
    bio = BioSerializer()
    # designation = GroupListSerializer()
    # department = GroupListSerializer()

    class Meta:
        model = Employee
        fields = ['user','bio','tax_id_number','account_number','joining_date','designation','department']

如何正确地在django中为此创建POST方法：

到目前为止，这就是我所拥有的：

class EmployeeCreateView(generics.CreateAPIView):
    queryset=Employee.objects.all()
    serializer_class=EmployeeSerializer


    def post(self, request, format=None):

        designation = Group.objects.get(id=request.data['designation'],)
        department = Group.objects.get(id=request.data['department'],)
        user =User.objects.get(id=request.data['user'],)
        bio =Bio.objects.get(id=request.data['bio'],)


        # user=User.objects.get(id=request.data['user'],)    
        employee = Employee.objects.create(
            tax_id_number=request.data['tax_id_number'],
            account_number=request.data['account_number'],
            joining_date=request.data['joining_date'],
            designation =designation,
            department =department,
            user=user,
            bio=bio,

            )

        return Response(status=status.HTTP_201_CREATE

d）

但是当我发布帖子请求时，我会在日志中收到以下内容：

 MultiValueDictKeyError at /hr/employee_create/
"'bio'"

我认为您不需要覆盖create()中的views.py。仅使用此选项，并根据需要覆盖序列化程序的create()方法（我认为这是DRF的良好策略）

class EmployeeCreateView(generics.CreateAPIView):
    queryset=Employee.objects.all()
    serializer_class=EmployeeSerializer

请求有效负载

{
    "user": "user data",
    "tax_id_number": 12344,
    "bio": {
        "field1": "foo",
        "field2": "bar"
    },
    "other fields": "values"

}
