包含的urlconf manager.urls没有任何模式 [英] The included urlconf manager.urls doesn't have any patterns in it

问题描述

解决方案：找到以下django片段，似乎工作正常
（ http://djangosnippets.org/snippets/2445/ ）

A solution: Found the following django snippet that seems to work fine (http://djangosnippets.org/snippets/2445/)

from django.utils.functional import lazy
from django.core.urlresolvers import reverse

#Workaround for using reverse with success_url in class based generic views
#because direct usage of it throws an exception.

reverse_lazy = lambda name=None, *args : lazy(reverse, str)(name, args=args)

显然，现在有一个 reverse_lazy 功能在django trunk。

Apparently, there is now a reverse_lazy function in django trunk.

更新：与我通话中的一个通用视图相反的一点：

Update: This error has something to do with me making a call to reverse inside a generic view:

class AddObjView(CreateView):
    form_class = ObjForm
    template_name = 'manager/obj_add.html'
    success_url = reverse('manager-personal_objs')

这是不是有效？

如果我不是通用的写这样的东西，它的作品：

If I instead of generic write something like this, it works:

def add_obj(request, pk):
    a=reverse('manager-personal-objs')
    return HttpResponse(a)

我有一个项目，其中有2个应用程序。每个应用程序都有其URL和视图。他们都工作正常，但在经理的应用程序，一旦我引用反向功能的视图（任何视图），我得到以下错误：
异常类型：不正确的配置
异常值：包含urlconf manager.urls没有任何模式

---

I have a project with 2 apps in it. Each app has its urls and views. They both work fine, but on the manager app, as soon as I reference the reverse function in the views(any view), I get the following error: Exception Type: ImproperlyConfigured Exception Value: The included urlconf manager.urls doesn't have any patterns in it

urls文件：

urlpatterns = patterns('',
    url(r'^$', ObjView.as_view(), name='manager-obj'),
    url(r'^add/$', AddObjView.as_view(), name='manager-add_obj'),
    url(r'^personal/$', PersonalObjsView.as_view(), name='manager-personal_objs'),    

）

异常位置：... site- package\django\core\urlresolvers.py在_get_url_patterns中，第283行

Exception Location: ...site-packages\django\core\urlresolvers.py in _get_url_patterns, line 283

我在整个网站都收到这个错误（编辑：这显然是因为试图导入manager.urls会导致错误）。如果我删除了include manager.urls，一切都恢复了工作;如果我删除了反向的呼叫，一切都很好;如果我尝试将manager.urls重写为一个更简单的版本，它会继续出现错误。

I get this error in the entire site(edit: this apparently happens because an attempt to import the manager.urls will result in the error). If I remove the include manager.urls, everything goes back to work; if I remove the call to reverse, everything is fine; if I try to rewrite manager.urls to a simpler version, it continues with the error.

我已经过了这么多次，似乎找不到任何东西

I've been over this many times, can't seem to find anything wrong.

编辑：root urls.py

edit:root urls.py

# coding=utf8
from django.conf.urls.defaults import patterns, include, url
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from django.views.generic.simple import direct_to_template

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Uncomment the admin/doc line below to enable admin documentation:
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),

    # Home Page
    url(r'^$', direct_to_template, {'template': 'home.html'}, name="home"),

    # manager
    url(r'^manager/', include('manager.urls')),

    # writing
    url(r'^writing/', include('writing.urls')),
)

urlpatterns += staticfiles_urlpatterns()

edit2：还应该注意的是，在管理应用程序中，url模板标记可以正常工作，如果我在另一个应用程序。
此外，每个url都有一个书面工作视图。

edit2: Should also be noted that the url template tag works fine in the manager app and the reverse call works if I do it on the other app. Also, every url has a written working view.

推荐答案

问题是您的URLConf尚未完成加载在您的基于类的视图尝试反转URL（AddObjView.success_url）之前。如果您希望在基于类的视图中继续使用反向，您有两个选项：

The problem is that your URLConf hasn't finished loading before your class based view attempts to reverse the URL (AddObjView.success_url). You have two options if you want to continue using reverse in your class based views:

a）您可以为您的类创建一个get_success_url（）方法，并且相反那里

a) You can create a get_success_url() method to your class and do the reverse from there

class AddObjView(CreateView):
    form_class = ObjForm
    template_name = 'manager/obj_add.html'

    def get_success_url():
        return reverse('manager-personal_objs')

b）如果您正在Django的trunk / dev版本上运行，那么可以使用reverse_lazy https://docs.djangoproject.com/en/dev/topics/http/urls/#reverse-lazy

b) If you are running on the trunk/dev version of Django, then you can use reverse_lazy https://docs.djangoproject.com/en/dev/topics/http/urls/#reverse-lazy

from django.core.urlresolvers import reverse_lazy

class AddObjView(CreateView):
    form_class = ObjForm
    template_name = 'manager/obj_add.html'
    success_url = reverse_lazy('manager-personal_objs')

选项b是未来版本的Django中首选的方法。

Option "b" is the preferred method of doing this in future versions of Django.
