Django:包含的urlconf core.urls中没有任何模式

我在使用基于类的视图和reverse_lazy时遇到了一些奇怪的问题。

调用网站时出现以下错误:

ImproperlyConfigured at /dashboard/student/
The included urlconf core.urls doesn't have any patterns in it

我的views.py:

class DashStudentMain(TemplateView):
    model_class = None
    template_name = 'learn/dashboard/snip_student_1.html'
    tab_list = {
        ("Main", reverse_lazy('dash_student_main_url')),
        #("History", reverse_lazy('dash_student_main_url'))
    }
    active_tab = "Main"

My core.urls:

from django.conf.urls.defaults import patterns, include, url
from django.contrib import admin
from django.views.generic import RedirectView
from django.conf import settings

admin.autodiscover()

urlpatterns = patterns(
    '',
    url(r'^$', 'core.views.home', name='home_url'),
    url(r'^home', 'core.views.home'),
    url(r'^dashboard/', include('tc_learn.dashboard.urls')),
    ...
)

我的tc_learn.dashboard.urls:

from django.conf.urls.defaults import patterns, url
from .views import DashStudentMain, DashStudentHistory

urlpatterns = patterns(
    # Student + Tabs
    url(r"^", DashStudentMain.as_view()),
    url(r"^student/$", DashStudentMain.as_view(), name="dash_student_main_url"),
    url(r"^student/history/$", DashStudentHistory.as_view(), name="dash_student_history_url"),

我已经

  • 重新启动服务器,以确保正确加载网址
  • 注释掉(“Main”,reverse_lazy('dash_student_main_url'))以确保urls.py语法正常
  • 删除了 url(r“^”,DashStudentMain.as_view())这一行,因为它还没有被使用,但没有它/ dashboard / student根本不起作用..

知道我可能缺少什么吗?谢谢!

编辑: 看起来这个问题来自tab_list对象。 当我通过tab_list = reverse_lazy('dash_student_main_url')直接分配对象时,代码工作正常。当我在列表中使用它时,它显示错误。有没有人知道这种情况的解决方法?

2 个答案:

答案 0 :(得分:9)

更改此代码:

tab_list = {
    ("Main", reverse_lazy('dash_student_main_url')),
    #("History", reverse_lazy('dash_student_main_url'))
}

为:

tab_list = [
    ("Main", reverse_lazy('dash_student_main_url')),
    #("History", reverse_lazy('dash_student_main_url'))
]

与您给变量的名称相反,您没有创建列表,而是set。元素在集创建时立即进行评估,因为集合需要更多地了解它们包含的值。将其更改为正确的列表将允许按照预期懒惰地评估元素。

答案 1 :(得分:2)

在tc_learn.dashboard.urls中:您缺少第一个参数(在您的情况下为空前缀)。将其更改为:

urlpatterns = patterns(
    '',
    url(r"^", DashStudentMain.as_view()),
    url(r"^student/$", DashStudentMain.as_view(), name="dash_student_main_url"),
    url(r"^student/history/$", DashStudentHistory.as_view(), name="dash_student_history_url"),
)

此外,如果你想让它代表一个空的,那么第一个正则表达式应该是r“^ $” 看看它是否有效。让我知道!
