python之django 1.8 中的 ImageField 类不在模板中显示图像

根据代码，图像应该显示在 index.html 模板上，但是 img src 似乎有一些问题

我的models.py

from django.db import models 
 
 
class Rockinfo(models.Model): 
   rock_name = models.CharField(max_length=200,default="ac/dc") 
   rock_img = models.ImageField(upload_to="%Y/%m/%d",default="1992/08/92") 
   rank = models.IntegerField(default=0) 
 
   def __str__(self):               
       return self.rock_name 

我的admin.py

from django.contrib import admin 
from .models import Rockinfo, Rockvids 
 
class ChoiceInline(admin.TabularInline): 
  model = Rockvids 
  extra = 10 
 
class RockinfoAdmin(admin.ModelAdmin): 
  fieldsets = [ 
    ('The Fucking Band',               {'fields': ['rock_name']}), 
    ('Image', {'fields': ['rock_img']}), 
  ] 
  inlines = [ChoiceInline]   
  list_display = ('rock_name', 'rock_img') 
  list_filter = ['rank'] 
  search_fields = ['rock_name'] 
 
 
admin.site.register(Rockinfo, RockinfoAdmin) 

我的应用程序的 urls.py

 from django.conf.urls import url 
 
 from . import views 
 
 urlpatterns = [ 
    url(r'^$', views.IndexView.as_view(), name='index'), 
 ] 

我项目的models.py

 from django.conf.urls import include, url 
 from django.contrib import admin 
 
  urlpatterns = [ 
     url(r'^rockinglist/', include('rockinglist.urls',  namespace="rockinglist")), 
     url(r'^admin/', include(admin.site.urls)), 
     ] 

我的views.py 文件

   from django.shortcuts import get_object_or_404, render 
   from django.http import HttpResponseRedirect, HttpResponse 
   from django.core.urlresolvers import reverse 
   from django.views import generic 
   from .models import Rockvids, Rockinfo 
 
 
   class IndexView(generic.ListView): 
   template_name = 'rockinglist/index.html' 
   context_object_name = 'latest_rockinfo_list' 
 
   def get_queryset(self): 
       return Rockinfo.objects.order_by('-rank')[:5] 

index.html 文件

   {% if latest_rockinfo_list %} 
   <ul> 
   {% for rockinfo in latest_rockinfo_list %} 
   <h1>{{ rockinfo.rock_name }}</a></li> 
   <img src="img\{{ rockinfo.rock_img }}" alt="ac/dc"> 
   {% endfor %} 
   </ul> 
   {% else %} 
   <p>No</p> 
   {% endif %} 

我认为问题出在图像的根目录上。不知何故 django 无法访问图像。我想显示 rock_name 以及相关的 rock_img。谁能帮我解决这个问题。在此先致谢。

请您参考如下方法:

在您项目的 urls.py 中，添加以下内容:

# your other imports here ... 
# ... 
from django.conf import settings 
from django.conf.urls.static import static 
 
urlpatterns = [ 
    # ... the rest of your URLs ... 
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) 

在你的 settings.py 文件中，确保你有这个:

MEDIA_URL = '/media/' 
 
MEDIA_ROOT = os.path.join(BASE_DIR, "media") 

在你的模板中:

<img src="{{ rockinfo.rock_img.url }}" alt="ac/dc"> 

注意:如果 BASE_DIR 未在您的设置中定义，请将其放在您的设置文件之上:

import os 
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
