Question

我在完成how to tango with django教程后构建我的第一个网站，我正在尝试使用模板语言添加一些图像，但我只得到一些蓝色的问号图标

models.py

from django.db import models

class Galery(models.Model):
    title = models.CharField(max_length = 120)

    def __unicode__(self):
        return self.title

class Image(models.Model):
    galery = models.ForeignKey(Galery)
    name = models.CharField(max_length = 50, unique = True)
    picture = models.ImageField(upload_to='media')
    description = models.CharField(max_length = 500)
    materials = models.CharField(max_length = 150)

    def __unicode__(self):
        return self.name

galery.html

{%extends 'home/base.html'%}
{%load static%}
{%block body%}
<div class="col-lg-12">
    <h1 class="page-header">My Projects</h1>
</div>
{%if image%}    
    {%for n in image%}  
        <div class="col-lg-3 col-md-4 col-xs-6 thumb">
            <a class="thumbnail" href="">
                <img class="img-responsive" src="{% static 'media/{{n.image.url}}' %}">
            </a>
        </div>
    {%endfor%}
{%endif%}

{%endblock%}

settings.py（part）

PROJECT_PATH = os.path.join(SETTINGS_DIR, os.pardir)
MEDIA_ROOT = os.path.join(PROJECT_PATH,'media')
TEMPLATE_DIRS = (
    TEMPLATE_PATH,
)
STATICFILES_DIRS = (
    STATIC_PATH,
)
STATIC_URL = '/static/'

MEDIA_URL = '/media/'

编辑：忘了提到我从管理员上传了一些图片

EDIT2：在我的urls.py中我有

if settings.DEBUG:
urlpatterns += patterns(
    'django.views.static',
    (r'media/(?P<path>.*)',
    'serve',
    {'document_root': settings.MEDIA_ROOT}), )

默认情况下，Django不提供用户上传的图像。通过添加以下URL conf来设置它：

from django.conf import settings
from django.conf.urls.static import static

urlpatterns = patterns('',
    # ... the rest of your URLconf goes here ...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

这仅适用于开发。在生产中，您需要以更具可扩展性的方式提供文件（直接来自HTTP服务器，甚至更好，来自文件存储服务，如S3或CDN。）
