Question

这是查询：

comment = AdditionalComment.objects.get(form = form, student = students[student])

在我的本地机器上完美运行。

我已将项目部署到DO VPS，每当我尝试访问视图时，即使我可以在管理面板中看到AdditionalComment，我也会收到此错误：

File "/home/smartsurvey/venv/lib/python3.6/site-packages/django/core/handlers/exception.py", line 41, in inner
    response = get_response(request)
  File "/home/smartsurvey/venv/lib/python3.6/site-packages/django/core/handlers/base.py", line 187, in _get_response
    response = self.process_exception_by_middleware(e, request)
  File "/home/smartsurvey/venv/lib/python3.6/site-packages/django/core/handlers/base.py", line 185, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)
  File "/home/smartsurvey/venv/lib/python3.6/site-packages/django/contrib/auth/decorators.py", line 23, in _wrapped_view
    return view_func(request, *args, **kwargs)
  File "/home/smartsurvey/smart-survey/forms/views.py", line 195, in view_replies
    comment = AdditionalComment.objects.get(form = form, student = students[student])
  File "/home/smartsurvey/venv/lib/python3.6/site-packages/django/db/models/manager.py", line 85, in manager_method
    return getattr(self.get_queryset(), name)(*args, **kwargs)
  File "/home/smartsurvey/venv/lib/python3.6/site-packages/django/db/models/query.py", line 380, in get
    self.model._meta.object_name
forms.models.DoesNotExist: AdditionalComment matching query does not exist.`

知道它可能是什么？如果您需要更多信息，请告诉我

Answer 1

我意识到我在查询用户评论之前是在查询数据库，所以我添加了一个if语句来检查他们是否已经回复了。

Answer 2

错误说：没有附加评论这样的参数。您需要创建AdditionalComment实例，然后才能获得它。

Django数据库查询适用于本地计算机，但不适用于服务器
