页面未找到，URL未解析

Question

我试图通过在网络浏览器中粘贴网址http://127.0.0.1:8000/upload_results/UniEX_HG1_A15来调用我的views.py中的函数，但请求失败，我无法理解为什么我的网址模式不起作用。

错误：

Page not found (404)
Request Method:     GET
Request URL:    http://127.0.0.1:8000/upload_results/UniEX_HG1_A15

Using the URLconf defined in varview.urls, Django tried these URL patterns, in this order:

    ^$ [name='show_index']
    ^admin/
    ^upload/ [name='varview_submission']
    ^upload_results/(?P<project_id>[0-9A-Za-z_]+)/ [name='varview_upload_results']
    ^validate/(?P<project_id>[0-9A-Za-z_]+)/ [name='varview_validate']
    ^filterallprojects/[0-9A-Za-z_]+ [name='varview_filterallprojects']
    ^project/(?P<project_id>[0-9A-Za-z_]+)/wgsmetrics/ [name='varview_wgsmetrics']
    ^project/(?P<project_id>[0-9A-Za-z_]+)/targetgenecoverage/ [name='varview_targetgenecoverage']
    ^project/(?P<project_id>[0-9A-Za-z_]+)/(?P<display_option>[0-9A-Za-z_]+)/ [name='varview_project']
    ^media\/(?P<path>.*)$

The current path, upload_results/UniEX_HG1_A15, didn't match any of these.

这是我的urls.py：

from django.conf import settings
from django.conf.urls import url
from django.conf.urls.static import static
from django.contrib import admin
from varview import views
from varview.forms import DataUploaderForm1, DataUploaderForm2, GetProjectIdForm

urlpatterns = [
    url(r'^$', views.show_index, name='show_index'),
    url(r'^admin/', admin.site.urls),
    url(r'^upload/', views.init_submission, name='varview_submission'),
    url(r'^upload_results/(?P<project_id>[0-9A-Za-z_]+)/', views.upload_results, name='varview_upload_results'), 
]

这已经有一段时间了，但与此同时我做了很多改变。最新的变化包括芹菜（djcelery）。索引页面和其他页面仍然有效。我已经阅读了许多与django-url相关的帖子，但无法理解。

谢谢您的帮助。

请注意您的网址有一个尾部斜杠，

^upload_results/(?P<project_id>[0-9A-Za-z_]+)/

但是您尝试访问没有尾部斜杠的URL

/upload_results/UniEX_HG1_A15

通常，Django将重定向到带有斜杠的URL。也许你的MIDDLEWARE设置不正确，或者你已经将APPEND_SLASH设置为False。
