Python/Django不追加Slash

Question

出于某种原因，Django没有在包含数字字符的变量末尾添加斜杠：

test_A

test_1

我确实安装了中间件和APPEND_SLASH = True。

有什么想法吗？谢谢!

url.conf：

from django.conf.urls import patterns, url
from dashboard import views

urlpatterns = patterns('',
    url(r'^$', views.index, name='index'),
    url(r'^environment/(?P<environment_name_url>\w+)/$', views.environment, name='environment'),)

models.py：

from django.db import models

class Environment(models.Model):
name = models.CharField(max_length=128, unique=True)
def __str__(self):
    return self.name

views.py：

def environment(request, environment_name_url):
    environment_name = environment_name_url.replace('_', ' ')
    context_dict = {'environment_name': environment_name}
    try:
        environment = Environment.objects.get(name=environment_name)
        pages = Page.objects.filter(environment=environment)
        context_dict['pages'] = pages
        context_dict['environment'] = environment
    except Environment.DoesNotExist:
        pass
    return render(request, 'dashboard/environment.html', context_dict)

错误：

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

    1. ^admin/
    2. ^dashboard/ ^$ [name='index']
    3. ^dashboard/ ^environment/(?P<environment_name_url>\w+)/$ [name='environment']
    4. media/(?P<path>.*)

The current URL, dashboard/environment/test_1, didn't match any of these.

您必须扩展正则表达式。问题不是斜杠没有附加，问题是没有一个urls匹配(不管有没有斜杠)。

简单的解决方案，要包含点，您应该更新正则表达式以也允许点：url(r'^environment/(?P<environment_name_url>[\w\.]-)/$', views.environment, name='environment'),)

您可以进一步改进它，以允许使用dash：url(r'^environment/(?P<environment_name_url>[\w\.-]+)/$', views.environment, name='environment'),)

后者甚至允许/测试-1.1_10/
