Question

我有一个模型，我希望将其显示为详细信息视图，我创建了一个列表视图，其中包含指向其详细视图的链接。我没有得到任何错误，但模板不呈现任何模型细节链接到DetailView

<a href="../ancillaries/{{ Ancillary.id }}" > Product </a>

模型

from django.db import models
from django.core.urlresolvers import reverse

class Ancillary(models.Model):
     product_code = models.CharField(max_length=60, null=True)
     type = models.CharField(max_length=120, null=True)
     product = models.CharField(max_length=120, null=True)
     standard = models.CharField(max_length=120,   null=True)
     measurement = models.CharField(max_length=120,  null=True)
     brand = models.CharField(max_length=120,   null=True)

     class Meta:
          verbose_name_plural = "Ancillaries"
     def get_absolute_url(self):
          return reverse('ancillaries')
     def __unicode__(self):
          return u'%s %s %s %s %s %s  %s' % (self.id, self.product_code, self.type, 
                                self.product, self.standard, 
                                self.measurement, self.brand)

查看

class AncillaryDetail(DetailView):
    model = Ancillary
    def get_context_data(self, **kwargs):

        context = super(AncillaryDetail, self).get_context_data(**kwargs)

       context['ancillary_list'] = Ancillary.objects.all()
       return context

网址

url(r'^ancillaries/(?P<pk>\d+)/', AncillaryDetail.as_view(template_name='ancillary-detail.html')),

模板

{% for ancillary_list in object_list %}
{{ Ancillary.product}}
{{ Ancillary.type }}
{{ Ancillary.brand }}
{{ Ancillary.measurement }}
{% endfor %}

Answer 1

您好像使用了documentation，但错误地调整了ListView示例。如果要显示单个模型实例，则DetailView是正确的视图。

正如@mrkre建议您应该为您的网址格式命名（虽然我会使用单数形式作为名称）。

url(r'^ancillaries/(?P<pk>\d+)/', AncillaryDetail.as_view(
                template_name='ancillary-detail.html'), name="ancillary_detail")

视图就是

class AncillaryDetail(DetailView):
    model = Ancillary

在模板ancillary-detail.html中，您使用默认名称object访问模型实例。

{{ object.product}}
{{ object.type }}
{{ object.brand }}
{{ object.measurement }}

Answer 2

尝试：

{% for ancillary in ancillary_list %}
    {{ ancillary.product}}
    {{ ancillary.type }}
    {{ ancillary.brand }}
    {{ ancillary.measurement }}
{% endfor %}

我建议使用url的名称：

url(r'^ancillaries/(?P<pk>\d+)/', AncillaryDetail.as_view(), name="ancillary_details")

<a href="{% url 'ancillary_details' pk=ancillary.pk %}">

将其放在DetailView

之后

template_name='ancillary-detail.html'

DetailView模板不显示模型数据
