Question

尝试安装django-likes时出现以下错误

NoReverseMatch at / post / 25 /

反向＆＃39;＆＃39;有参数＆＃39;（＆＃39; posts-post＆＃39;，25,1）＆＃39;和关键字参数＆＃39; {}＆＃39;未找到。尝试了0种模式：[]

异常位置：/Users/Pete/.virtualenvs/innerlocal-mvp/lib/python2.7/site-packages/django/core/urlresolvers.py in _reverse_with_prefix，第463行

我不知道从哪里开始这个错误，我已经做了很多搜索，但没有任何结果。

我认为这是指：

def single_post(request, id):
    post = get_object_or_404(Post, id=id)
    ...

    return render(request, 'posts/single_post.html', locals())

在html中{％like post％}。

并从生成的html中突出显示该行：

<a class="liker" href="{% url like content_type content_obj.id 1 %}" rel="nofollow">{% trans "I Like" %}</a>

我使用的是Django 1.7，如果这是一个问题，我不会感到惊讶。

非常感谢任何帮助!!

根据要求提供额外设置：

urls.py行（首先是app，第二行，django-like url：

url(r'^', include('posts.urls')),
(r'^likes/', include('likes.urls')),

和帖子应用的urls.py：

from django.conf import settings
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView
from views import PostDelete

urlpatterns = patterns('posts.views',
     # (r'^', 'home'),
     url(r'^$', 'all_posts', name='home'),
     url(r'^post/(?P<id>\w+)/$', 'single_post', name='single_post'),
     url(r'^new-post/$', 'new_post', name='new_post'),
     url(r'^search/$', 'search', name='search'),
     url(r'^delete/(?P<pk>\d+)/$', PostDelete.as_view(),
         name='entry_delete'),
)

已安装的应用：

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.gis',
    'django.contrib.sites',
    ....
    'secretballot',
    'likes',
)

中间件类：

MIDDLEWARE_CLASSES = (
    'django.middleware.gzip.GZipMiddleware',
    'pipeline.middleware.MinifyHTMLMiddleware',
    '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',
    'django.contrib.redirects.middleware.RedirectFallbackMiddleware',
    'secretballot.middleware.SecretBallotIpMiddleware',
    'secretballot.middleware.SecretBallotIpUseragentMiddleware',
    'likes.middleware.SecretBallotUserIpUseragentMiddleware',
)

模板上下文处理器：

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.request",
    "allauth.account.context_processors.account",
    "allauth.socialaccount.context_processors.socialaccount",
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.static",
    "django.core.context_processors.media",
    "django.contrib.messages.context_processors.messages",
)

原来应用程序代码需要更改：

在likes.html中

这

<a class="liker" href="{% url like content_type content_obj.id 1 %}" rel="nofollow">{% trans "I Like" %}</a>

到

<a class="liker" href="{% url 'like' content_type content_obj.id 1 %}" rel="nofollow">{% trans "I Like" %}</a>

ie - 'like'周围的引号

NoReverseMatch实现django-likes
