Question

我对Django的urls.py的正则表达式部分有疑问。我想为每个输入的用户显示一个页面。我的views.py看起来像：

def tekent(request):
    tumentry = Entry.objects.get(id=id)

    return render_to_response("baslik/tekentry.html", locals(), context_instance=RequestContext(request))


def tek(request, slug):
    basliklar = Baslik.objects.filter(active=True).order_by('-updated')
    baslik = Baslik.objects.get(slug=slug)
    entryler = baslik.entry_set.all()
    form2 = EntryForm(request.POST or None)

    if form2.is_valid():
        entry = form2.save(commit=False)
        entry.baslik = baslik
        entry.user = request.user
        entry.save()
        return HttpResponseRedirect('/entry/%s'%(entry.id))


    return render_to_response("baslik/tek.html", locals(), context_instance=RequestContext(request))

我的主要urls.py（不是应用程序）看起来像这样：

from baslik import *
urlpatterns = patterns('',
url(r'^entry/(?P<Entry.id>)/$', 'tekent', name = "tek_entry"),
)

当我在网络浏览器上添加条目时，会引发如下错误：

DoesNotExist at /baslik/entry4/
Baslik matching query does not exist.
Request Method: GET
Request URL:    http://127.0.0.1:8000/baslik/entry4/
Django Version: 1.6.5
Exception Type: DoesNotExist
Exception Value:    
Baslik matching query does not exist.
Exception Location: /Users/malisit/Django/sozluk/lib/python2.7/site-packages/django/db/models/query.py in get, line 310
Python Executable:  /Users/malisit/Django/sozluk/bin/python

我应该怎么做才能解决这个问题？感谢。

Answer 1

尝试 url(r'^entry/(?P<id>\d+)/$', 'tekent', name = "tek_entry"),

为什么不使用基于类的视图？ DetailView对于这些事情非常方便。

你有一些问题：

您的网址格式无效，@ maremare解释了如何修复它。
您呼叫的网址与您的模式不匹配。您的网址为/baslisk/entry4/，但您的模式为entry/。
您的查看方法tekent不会带任何参数，因此即使您要修复网址格式，也不会调用您的查看方法。
您正在使用locals()。不要这样做。

以下是从urls.py开始修复这些内容的方法：

from baslik.views import tekent
# other imports

urlpatterns = patterns('',
  url(r'^entry/(?P<id>\d+)/$', tekent, name = "tek_entry"),
)

您的views.py

from django.shortcuts import render
from django.shortcuts import redirect
from django.shortcuts import get_object_or_404

def tekent(request, id):
    tumentry = get_object_or_404(Entry, id=id)
    return render(request, "baslik/tekentry.html", {'tumentry': tumentry})

def tek(request, slug):
    baslik = get_object_or_404(Baslik, slug=slug)
    basliklar = Baslik.objects.filter(active=True).order_by('-updated')
    entryler = baslik.entry_set.all()
    form2 = EntryForm(request.POST or None)

    if form2.is_valid():
        entry = form2.save(commit=False)
        entry.baslik = baslik
        entry.user = request.user
        entry.save()

        return redirect('tek_entry', id=entry.id)

    ctx = {'form2': form2, 'baslikar': baslikar, 'entryler': entryler}

    return render(request, "baslik/tek.html", ctx)

Django urls正则表达式不起作用
