使用NoReverseMatch异常的mezzanine.mobile

Question

我对Mezzanine非常陌生，很难获得视图移动站点在 index.html中可用的选项。

设置

在settings.py中，我指定了以下内容：

INSTALLED_APPS = (
    "newsletters",
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.messages",
    "django.contrib.contenttypes",
    "django.contrib.redirects",
    "django.contrib.sessions",
    "django.contrib.sites",
    "django.contrib.sitemaps",
    "django.contrib.staticfiles",
    "mezzanine.boot",
    "mezzanine.conf",
    "mezzanine.core",
    "mezzanine.generic",
    "mezzanine.pages",
    "mezzanine.blog",
    "mezzanine.forms",
    "mezzanine.accounts",
    "mezzanine.mobile",
)
MIDDLEWARE_CLASSES = (    
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    "mezzanine.core.middleware.UpdateCacheMiddleware",
    "mezzanine.core.request.CurrentRequestMiddleware",
    "mezzanine.core.middleware.RedirectFallbackMiddleware",
    "mezzanine.core.middleware.TemplateForDeviceMiddleware",
    "mezzanine.core.middleware.TemplateForHostMiddleware",
    "mezzanine.core.middleware.AdminLoginInterfaceSelectorMiddleware",
    "mezzanine.core.middleware.SitePermissionMiddleware",
    "mezzanine.pages.middleware.PageMiddleware",
    "mezzanine.core.middleware.FetchFromCacheMiddleware",
)

在我的index.html里

{% ifinstalled mezzanine.mobile %}
  <span class="separator">|</span>
  <a href="{% url "set_device" "mobile" %}?next={{ request.path }}">{% trans "View Mobile Site" %}</a>
  {% endifinstalled %}

但是当我访问我的index.html时，我会得到这个错误。

Reverse for 'set_device' with arguments '('mobile',)'
  and keyword arguments '{}' not found.
0 pattern(s) tried: []

知道我为什么会有这个例外吗？

Answer 1

异常意味着django在urls配置中找不到匹配的内容。

您在根urls.py中添加了一些吗？把文件寄出去。

也许你错过了在其中加入这样的东西：

urls.py

urlpatterns = [
    ...
    url(r'the_app_name/', include('the_app_name.urls')),
    ...
]

因此，您应该有一个名为set_device的url，它接受“mobile”作为参数，如下所示

app_name = 'the_app_name'
urlpatterns = [
    url(r'^my_url/(?P<type>(mobile|...))/$', my_view, name='set_device'),
...

我们应该把它建在CMS里还是你自己的？
