如何在django中获取数据的关系模型

Question

我正在查询用户数据。作为回应，我得到了以下输出。

{
"id": 33,
"username": "dummy",
"email": "[e-mail]",
"role": 49,
"is_active": true,
"staff": true,
"admin": false,
"last_login": "2022-07-27T06:41:03.709582Z",
"update_time": "2022-08-02T07:53:11.241320Z",
"create_time": "2022-07-26T14:34:35.161434Z"
}

正如您所看到的，这个用户模型与一个id为49的角色存在外部关系。我想通过accounts实例获得JSON中角色的所有详细信息。我该怎么做？例如：

{
"id": 33,
"username": "dummy",
"email": "[e-mail]",
"role": {
"id":49
"projects":true,
"notifications":true,
"emails":true,
"update_time": "2022-08-02T07:53:11.241320Z",
"create_time": "2022-07-26T14:34:35.161434Z"
},
"is_active": true,
"staff": true,
"admin": false,
"last_login": "2022-07-27T06:41:03.709582Z",
"update_time": "2022-08-02T07:53:11.241320Z",
"create_time": "2022-07-26T14:34:35.161434Z"
}

此API的我的视图。

@api_view(['GET'])
@permission_classes([IsAuthenticated])
def all_platform_user_list(request):
if request.method == 'GET':
users = User.objects.get_all_platform_users()
total_count = len(users)
total_page = total_page_counter(total_count)
paginator = CustomPagination()
paginator.page_size = 20
result_page=None
try:
result_page = paginator.paginate_queryset(users, request)
except:
pass
serializer = CreateAccountsSerializer(result_page, many=True)
return Response({"message": "Here are results","total_page":total_page,"total_count":total_count, "data": serializer.data},status=status.HTTP_200_OK)
else:
return Response({"message": "No User"},status=404)

Answer 1

您可能对CreateAccountsSerializer有问题。您需要添加有关序列化程序的信息，这些信息必须表示角色字段中的数据。

class WarehouseSerializer(serializers.ModelSerializer):
role = RoleSerializer(many=True/False, read_only=True/False)
class Meta:
model = Warehouse
fields = ['id', 'username', ... 'role']
