我觉得这将是一个令人尴尬的问题，但我无法找到我尝试过谷歌的答案，但我感到相当沮丧，所以我决定在这里问。我在 django 的模板文件中有这个代码片段

{% url cal.views.month year month "next" %}

我运行代码并得到此错误 Reverse for 'courseCalendar.views.month' 参数 '(2013, 9, u'next')' not found

为什么当我尝试在字符串中传递变量时，它也会将 u 放在那里。这是非常令人沮丧的，我真的很感激某人的两美分。

编辑：如果我不包含字符串“next”并使用变量代替年和月变量，那么一切正常，所以这不是 url 问题或模板问题。

网址模式

from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
    url(r'', 'courseCalendar.views.main'),
    url(r'^month/(?P<year>\d{4})/(?P<month>\d{2})/(?P<change>[a-z])/$', 'courseCalendar.views.month', name="month"),

)

更改为以下内容：

在您的视图文件中：

def month(request, year=1, month=1, change="None"):

在您的网址文件中：

url(r'^month/(?P<year>\d{4})/(?P<month>\d{2})/(?P<change>\w+)/$', 'courseCalendar.views.month', name="month"),

更改为上述内容后，如果您收到错误，请在此处发布错误消息。
