我想从表单中获取发布数据并显示它们。 我使用“{%url uasite1.views.sell_detail sell_detail.pk%}”来根据他们的pk提取数据。
然而,只有[NoReverseMatch···,反向'uasite1.views.sell_detail'与参数'('',)'和关键字参数'{}'找不到。]出现了。 我的代码出了什么问题?
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})
urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^sechand/$','uasite1.views.sell_create'),
url(r'^sechand/(\d+)/$', 'uasite1.views.sell_detail'),

更改
<a href="{% url uasite1.views.sell_detail sell_detail.pk %}">
于:
<a href="{% url uasite1.views.sell_detail sell.pk %}">

有几个错误。
1:更改您的网址
url(r'^sechand/(\d+)/$', 'uasite1.views.sell_detail'),
到
url(r'^sechand/(P<pk>\d+)/$', 'uasite1.views.sell_detail'),
这使得url接受通过pk
传递给视图的参数。
2:您的Electronics()
视图建议您将列表传递给模板,因此您需要更新模板以迭代此列表并适当地呈现列表中的每个项目。并确保正确使用变量名称。
{% block content %}
{%for sell in latest_sell_list %}
<p><a href="{% url uasite1.views.sell_detail sell.pk %}">{{ sell.subject }}</a></p>
{%endfor%}
{% endblock %}
