NoReverseMatch（与pk相关）：django

我想从表单中获取发布的数据并显示它们。 我使用“{%url uasite1.views.sell_detail sell_detail.pk%}”根据pk提取数据

然而，只有[诺维瑟维奇]・・・, 与“uasite1.views.sell_detail”相反，未找到参数“（“”，）”和关键字参数“{}”。]出现。 我的密码怎么了

models.py

from django.db import models
from django.forms import ModelForm

class Sell(models.Model):
    subject = models.CharField(max_length=100)
    price = models.CharField(max_length=100)
    condition = models.CharField(max_length=100)
    email = models.EmailField()
    body = models.CharField(max_length=200)

forms.py

from django.forms import ModelForm
from uasite1.models import Sell

class SellForm(ModelForm):
    class Meta:
        model = Sell

views.py

from django.shortcuts import render_to_response,get_object_or_404
from django.http import HttpResponseRedirect
from uasite1.forms import SellForm
from uasite1.models import Sell
from django.template import RequestContext


def sell_detail(request, pk):
    sell = get_object_or_404(Sell, pk=int(pk))
    return render_to_response('sell_display.html',{'sell':sell})

def sell_create(request):
    context = {}
    if request.method == 'POST':
        form = SellForm(request.POST)
        if form.is_valid():
            new_sell = form.save()
            return HttpResponseRedirect('/sechand/%d/' % new_sell.pk)
    else:
        form = SellForm()
    context['form'] = form
    return render_to_response('sell.html',context,context_instance = RequestContext(request))

def Electronics(request):
    latest_sell_list = Sell.objects.all()[:5]
    return render_to_response('electronics.html',{'latest_sell_list':latest_sell_list})

url.py

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^sechand/$','uasite1.views.sell_create'),

有几个错误

1：更改您的url

url(r'^sechand/(\d+)/$', 'uasite1.views.sell_detail'),

到

谢谢，但还是不行。显示屏显示[与'uasite1.views.sell_detail'相反，未找到参数'（''，'）和关键字参数'{}.]和[

]在“模板渲染期间出错”中突出显示，[将渲染返回到_响应（'electronics.html'，{'latest_sell_list:latest_sell_list}）]在“回溯”中突出显示。谢谢，但结果仍然显示“NoReverseMatch error”[与'uasite1.views.sell_detail'相反，未找到参数'（1，）'和关键字参数“{}”。]尽管将[arguments'（''，）'更改为[arguments'（1，）]。此外，在我将“P”添加到我的url.py后，“sell_display”页面开始不工作（页面未找到（404）at）可能是我的代码有其他问题？在我将“P”添加到我的代码后，它成功地工作了！非常感谢你。

url(r'^sechand/(P<pk>\d+)/$', 'uasite1.views.sell_detail'),

{% block content %}

    {%for sell in latest_sell_list %}
        <p><a href="{% url uasite1.views.sell_detail sell.pk %}">{{ sell.subject }}</a></p>

    {%endfor%}
