models.py

class Album(models.Model):
    title = models.CharField("Название альбома", max_length=100)
    slug = models.SlugField("Ссылка на альбом", max_length=100, unique=True)
    img = models.ImageField("Изображение альбома", upload_to='images', 
            help_text='Размер изображения 200px на 200px')
    created_date = models.DateTimeField(default=timezone.now)
    published_date = models.DateTimeField(blank=True, null=True)

class Photo(models.Model):
    title = models.CharField("Название фотографии", max_length=100)
    album = models.ForeignKey(Album, related_name='Альбом')
    img = models.ImageField("Фото", upload_to='images', 
            help_text='Желательно не большой размер')

if settings.DEBUG:

urls.py - 项目

from django.conf.urls import url, include

urlpatterns = [
    url(r'^admin/', admin.site.urls),

settings.py

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static/')

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

模板

{% extends "gallery/base.html" %}
{% load thumbnail %}
{% block title %}My Gallery{% endblock %}

{% block text %} 
    {% for album in my_album %}

        <a href='{{ album.slug }}'>
        <img src="{{ album.img.url}}" alt="{{ album.title }}">

          <!-- {% thumbnail album.img "200x200" crop="center" as im %}
            <img src="{{ im.url }}" alt="{{ im.title }}" width="{{ im.width }}" 
        height="{{ im.height }}">
            {% endthumbnail %} -->

        </a>

如果在setting.py我做MEDIA_URL =＆＃39;媒体/图片＆＃39;它会工作，但只有专辑模板，如果你去看专辑照片，那里的照片也会显示同样的错误...实际上我无法理解并意识到如何访问文件夹媒体，只需将任何内容放在这里我需要的东西。帮帮我...
