未找到页面，未解析 URL

Question

我正在尝试通过在 Web 浏览器中粘贴 URL 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，我看不出为什么我的 URL 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'), 
]

这已经在一段时间前工作了，但与此同时我做了很多改变。 最新的变化是包括芹菜（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，但无法弄清楚。

感谢您的帮助。

注意你的网址有一个斜杠，

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

但您尝试访问的 URL 不带斜杠

/upload_results/UniEX_HG1_A15

通常，Django 会重定向到带有斜杠的 URL。可能您的MIDDLEWARE 设置不正确，或者您将APPEND_SLASH 设置为False。
