在 projects/urls.py 我有：
urlpatterns = patterns('bizteen.projects.views',
url(r'^browse/$', 'browse', name='projects-browse-main'),
url(r'^browse/(\d+)/$', 'browse', name='projects-browse'),
url(r'^create/$', 'create', name='projects-create'),
url(r'^(\d+)/$', 'view_project', name='projects-view'),
)
在模板中我有：
<a href="{% url projects-browse-main %}">Browse projects</a>
但是出现了一个错误。
TemplateSyntaxError at /
Caught an exception while rendering: Reverse for 'bizteen.projects-browse-main' with arguments '()' and keyword arguments '{}' not found.
我能弄清楚的最多的是名称被视为视图。为什么会发生这种情况？
来自 bizteen.projects.views：
from django.shortcuts import render_to_response
from django.http import HttpResponse, HttpResponseRedirect
from bizteen.projects.models import Project, ProjectComment
from django.template import RequestContext
def browse(request, page=0):
page_start = page * 25
page_end = page_start + 25
project_list = Project.objects.order_by('date_created').reverse([page_start:page_end]
return render_to_response('browse_projects.html', {'project_list': project_list}, context_instance=RequestContext(request))
和主要的 urls.py：
from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
(r'^users/', include('bizteen.userthings.urls')),
(r'^projects/', include('bizteen.projects.urls')),
url(r'^$', 'bizteen.userthings.views.home', name='main-home'),
url(r'^profile/$', 'bizteen.userthings.user-profile'),
url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
url(r'^admin/(.*)', admin.site.root),
url(r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': 'templates/static'}),
)
