error
Request Method: GET
Request URL:         http://127.0.0.1:8000/admin/info/airimage/1/media/Ataturk_Havalimani_2.jpg/
airimage object with primary key u'1/media/Ataturk_Havalimani_2.jpg' does not exist.
You're seeing this error because you have DEBUG = True in your Django settings file.          Change that to False, and Django will display a standard 404 page.

我的settings.py

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


SECRET_KEY = 'amln51jyuo*wj2@g6k3vdd^@2)&84i#1@n2xvgx7hh#bpf7(l!'

DEBUG = True

TEMPLATE_DEBUG = True

ALLOWED_HOSTS = [] .......

urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()


urlpatterns = patterns('',
# Examples:
# url(r'^$', 'tav.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),

url(r'^admin/', include(admin.site.urls)),
)

和我的文件夹内容

airimage模型

class airimage(models.Model):
    stuff_image = models.FileField(upload_to="media/")
    airno=models.ForeignKey(airandoto)

    def __unicode__(Self):
        return self.airno
    class Meta: 
        verbose_name_plural="AirImage"

Answer 1

您试图错误地访问图像。你可以发布airimage模型吗？有问题的图像的主键看起来是1，但是你要向URL添加额外的信息，这使得Django认为你正在寻找主键为'1 / media / Ataturk_Havalimani_2.jpg'的行，绝对不存在。

....具有主键的对象......不存在django
