Question

实际上我尝试获取产品详细信息，但是当我转到127.0.0.1:8000/mobiles/motorola-moto-g-16gb时，它正在加载模板但没有显示任何内容，甚至没有显示任何内容错误。

注意：＆＃39;手机＆＃39;是url中的类别，休息是您可以看到的产品型号中的slug。

models.py

from django.db import models
from django.utils.text import slugify

class Category(models.Model):
   name = models.CharField(max_length=128, unique=True)

def __unicode__(self):
    return self.name


class Product(models.Model):
    title = models.CharField(max_length=140)
    slug = models.SlugField(null = True, blank = True)
    imgurl = models.CharField(max_length=500)
    price = models.CharField(max_length=100)
    category = models.ForeignKey(Category)

    def save(self, *args, **kwargs):
         if not self.id:
            self.slug = slugify(self.title)
    super(Product, self).save(*args, **kwargs)

def __unicode__(self):
    return self.title

views.py

from django.shortcuts import render_to_response, get_object_or_404, Http404
from django.template import RequestContext
from cat.models import Category, Product 

def detail(request, slug, category_name_url):
try:
    category = Category.objects.get(name=category_name_url)
    product = Product.objects.get(slug=slug)

except Product.DoesNotExist:
    raise Http404

return render_to_response('product/detail.html', {'product': product, 'category_name': category_name_url})

urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin
from cat import views

urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^(?P<category_name_url>\w+)/$', views.category, name='category'),
url(r'^(?P<category_name_url>\w+)/(?P<slug>[-\w]+)$', views.detail , name='detail'),
)

产品/ detail.html

<h1>{{ object.title }}</h1>
<p> {{ object.price }}</p>
<img src="{{ object.imgurl }}">

Answer 1

因为你正在传递＆＃39;产品＆＃39;在您的环境中，您必须使用＆＃39; product＆＃39;在你的模板中。

return render_to_response('product/detail.html', {'product': product, 'category_name': category_name_url})

因此，模板代码应为：

<h1>{{ product.title }}</h1>
<p> {{ product.price }}</p>
<img src="{{ product.imgurl }}">

Django：细节没有显示，没有错误
