一个查询接口，到时访问时，报错了，异常：

AttributeError: Got AttributeError when attempting to get a value for field `belong_project_id` on serializer `ModuleInfoSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `ModuleInfo` instance.
Original exception text was: 'ModuleInfo' object has no attribute 'ProjectInfo'.
[30/Aug/2019 12:22:42] "POST /api/module/query HTTP/1.1" 500 16990

只要去掉 ModuleInfoSerializer 中的 belong_project_id = serializers.IntegerField(source='ProjectInfo.id') 就可以访问成功，但是调用创建接口的时候，去掉刚才那个就会报错，不知道如何去修改代码，希望获得解答，该如何修改我的代码，网上搜索疑是我的数据源有问题
