我在谷歌上搜索了很多关于如何在模板中使用"url"标签的答案，结果发现很多回复说"你只需将其插入模板，并将其指向你想要的url视图".好吧，这对我来说没有什么乐趣:(我已经try 了所有可能的排列方式，并把在这里发帖作为最后的手段.).
所以事情就是这样了.我的urls.py如下所示:
from django.conf.urls.defaults import *
from login.views import *
from mainapp.views import *
import settings
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Example:
# (r'^weclaim/', include('weclaim.foo.urls')),
(r'^login/', login_view),
(r'^logout/', logout_view),
('^$', main_view),
# Uncomment the admin/doc line below and add 'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
# (r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
(r'^admin/', include(admin.site.urls)),
#(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': '/home/arthur/Software/django/weclaim/templates/static'}),
(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),
)
我的"login"目录中的"views.py"如下所示:
from django.shortcuts import render_to_response, redirect
from django.template import RequestContext
from django.contrib import auth
def login_view(request):
if request.method == 'POST':
uname = request.POST.get('username', '')
psword = request.POST.get('password', '')
user = auth.authenticate(username=uname, password=psword)
# if the user logs in and is active
if user is not None and user.is_active:
auth.login(request, user)
return render_to_response('main/main.html', {}, context_instance=RequestContext(request))
#return redirect(main_view)
else:
return render_to_response('loginpage.html', {'box_width': '402', 'login_failed': '1',}, context_instance=RequestContext(request))
else:
return render_to_response('loginpage.html', {'box_width': '400',}, context_instance=RequestContext(request))
def logout_view(request):
auth.logout(request)
return render_to_response('loginpage.html', {'box_width': '402', 'logged_out': '1',}, context_instance=RequestContext(request))
最后，login_view指向的main.html如下所示:
<html>
<body>
test! <a href="{% url logout_view %}">logout</a>
</body>
</html>
那为什么我每次都收到‘NoReverseMatch’呢？
*(在一个稍微不同的注释中，我必须在我所有的render to response的末尾使用'context_instance=RequestContext(request)"，因为否则它将无法识别我模板中的{MEDIA_URL}，并且我无法引用任何css或js文件.我不知道这是为什么.(对我来说似乎不合适)*
