Django我的模型没有从文件传输到文件

Question

我正在让我的菜单项显示在ListView页面上，但是当我单击链接时，没有任何数据正确显示。

这里是我的菜单carousel.html

{% for item in object_list %} 
    <li> 
     <div class="impx-menu-page-item"> 
     <div class="impx-menu-page-content"> 
      <h4><a href="/menu/{{ item.id }}">{{ item.title }}</a></h4> 
      <div class="impx-menu-page-price"> 
       <h5>${{ item.price }}</h5> 
      </div> 
      <p>{{ item.description }}</p> 
     </div> 
     </div> 
    </li> 
    {% endfor %} 

而且这样的作品，现在这里是破碎的一部分，当我到/菜单/ 1 /菜单/“无论数量”

<div class="container"> 
     <div class="row"> 
      <h3><a href="/menu/{{ item.id }}"></a>{{ item.title }}</h3> 

     </div> 
     <div class="row"> 
      <div class = "col-sm-12 col-md-4"> 
       <img src="{{ item.image.url }}" height="300px" width="300px" class = "img img-responsive thumbnail"/> 
      </div> 
      <div class = "col-sm-12 col-md-4"> 
       <h6>Price: ${{ item.price }}</h6> 
       <h6>Materials: {{ item.description }}</h6> 
      </div> 
      <div class = "col-sm-12 col-md-4"> 
       <p>{{ item.description|safe|linebreaks }}</p><br /><br /> 
       <hr /> 
       <h5></h5> 

      </div> 
      <br><br> 
     </div> 
    </div> 

这是在我的浏览器

<div class="container"> 
    <div class="row"> 
     <h3><a href="/menu/"></a></h3> 

    </div> 
    <div class="row"> 
     <div class = "col-sm-12 col-md-4"> 
      <img src="" height="300px" width="300px" class = "img img-responsive thumbnail"/> 
     </div> 
     <div class = "col-sm-12 col-md-4"> 
      <h6>Price: $</h6> 
      <h6>Materials: </h6> 
     </div> 
     <div class = "col-sm-12 col-md-4"> 
      <p><p></p></p><br /><br /> 
      <hr /> 
      <h5></h5> 

     </div> 
     <br><br> 
    </div> 
</div> 

这里显示是我的urls.py

from django.conf.urls import url, include 
from django.views.generic import ListView, DetailView 
from django.contrib import admin 
from . import views 
from home.models import Menu 


urlpatterns = [ 
    url(r'^$', views.home, name="home"), 
    url(r'^menu/$', ListView.as_view(
         queryset=Menu.objects.all().order_by("-title")[:25], 
         template_name="menu-carousel.html")), 
    url(r'^menu/(?P<pk>\d+)/$', DetailView.as_view(
         model = Menu, 
         template_name="menu-item.html")), 
] 

，这里是我的models.py

from django.db import models 
from django.conf import settings 

class Menu(models.Model): 
    title = models.CharField(max_length = 140) 
    price = models.IntegerField() 
    description = models.TextField() 
    image = models.ImageField(upload_to = 'media/') 
    menu = models.CharField(max_length = 10) 

    def __str__(self): 
     return self.title

我想你已经使用的DetailView模板错误的上下文对象名称。更多详细信息通过链接：

https://docs.djangoproject.com/es/1.9/ref/class-based-views/mixins-single-object/#django.views.generic.detail.SingleObjectMixin.get_context_object_name

尝试与{{menu.id}}而不是{{item.id}}显示菜单项的ID。您也可以使用django调试模板查看所有上下文对象。
