django - 从 djangorestframework 获取异常

问题描述

我从 djangorestframework 的 JSONEncoder 类中得到以下异常：

Traceback:

File "/home/ubuntu/Envs/env_md/lib/python3.6/site-packages/django/core/handlers/exception.py" in inner
  34.             response = get_response(request)

  238.         **kw).encode(obj)

File "/usr/lib/python3.6/json/encoder.py" in encode
  199.         chunks = self.iterencode(o, _one_shot=True)

File "/usr/lib/python3.6/json/encoder.py" in iterencode
  257.         return _iterencode(o, 0)

File "/home/ubuntu/Envs/env_md/lib/python3.6/site-packages/rest_framework/utils/encoders.py" in default
  56.         elif (coreapi is not None) and isinstance(obj, (coreapi.Document, coreapi.Error)):

Exception Type: AttributeError at /v0/ui/website/subject-assignment/
Exception Value: module 'coreapi' has no attribute 'Document'

所以，基本上，这是说我的应用程序（coreapi）没有 Document 属性。所有其他 api 工作正常，但它在一个特定的 api 中给出了这个错误。我也找不到该 api 的任何不同之处。djangorestframework 有什么问题，或者我应该怎么做才能调试？

注意：我使用的是 django 2.1.4，djangorestframework==3.9.0，python 版本是 3.6.5。
