Question

我按照此示例将文档上传到AWS（https://github.com/sibtc/simple-s3-setup/tree/master/s3-example-static-and-media）。我现在添加了一项功能，该功能允许用户删除上传的文档。

我收到错误消息“ django.urls.exceptions.NoReverseMatch：'mysite'不是注册的名称空间”。接下来是/home/ubuntu/.local/lib/python3.6/site-packages/django/urls/base.py中的参数值：
args [1]; current_app''; current_ns无； current_path无； kwargs {}; ns'mysite'; ns_converters {}; ns_pattern'';零件['delete'，'mysite'];路径[];字首 '/'; resolve_path [];解析器; urlconf'mysite.urls';查看“删除”；视图名'mysite：delete'

以下是我进行过更改的文件：
（1）mysite / core / views.py
class DocumentCreateView(CreateView): model = Document fields = ['upload', ] success_url = reverse_lazy('home')

   def get_context_data(self, **kwargs):
       context = super().get_context_data(**kwargs)
       documents = Document.objects.all()
       context['documents'] = documents
       return context

（下面是我添加的。我可能需要在此处添加一些代码以使删除工作正常进行）
class DocumentDeleteView(DeleteView): model = Document fields = ['upload', ] success_url = reverse_lazy('home')

   def get_context_data(self, **kwargs):
       context = super().get_context_data(**kwargs)
       documents = Document.objects.all()
       context['documents'] = documents
       return context

（2）mysite / urls.py
app_name = 'mysite' urlpatterns = [ url(r'^$', views.DocumentCreateView.as_view(), name='home'), *(below was added by me)* path('<int:pk>/delete/', views.DocumentDeleteView.as_view(), name='delete'), ]

（3）mysite / core / templates / core / document_form.html：
我还在下面的第27行中添加了以下代码 https://github.com/sibtc/simple-s3-setup/blob/master/s3-example-static-and-media/mysite/core/templates/core/document_form.html
<td><a href="{% url 'mysite:delete' document.id %}">Delete</a></td>
（如果我将“ mysite：delete”更改为“ delete”，则会收到“未找到“ delete”的反向名称。“ delete”不是有效的视图函数或模式名称。”）

使用DeleteView删除对象，得到“'mysite'不是注册的名称空间”
