Django管理员通过ImageField链接到图像

Question

我已经设置了一个活动的Django模型,其中包含以下字段:

class Activity(models.Model):
    ...
    thumbnail = models.ImageField(upload_to="thumbs/", blank=True, null=True)

通过管理界面,我可以上传一个正确放置在主目录的thumb文件夹中的图像.当我尝试编辑我创建的活动时,界面显示:Currently: thumbs/image.png这是指向的超链接http://localhost:8000/media/thumbs/image.png.当我单击此链接时,我收到404页面找不到错误.如何才能获得指向我上传的图像的链接？如果可能,如何直接在管理界面中显示图像？

编辑:

MEDIA_ROOT = '/Users/.../mysite/media/'; MEDIA_URL = 'http://localhost:8000/media/';

urls.py的内容:

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

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

谢谢!

Answer 1

settings.py

from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
)+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

urlpatterns += staticfiles_urlpatterns()

models.py

class Activity(models.Model):
    ...
    thumbnail = models.ImageField(upload_to="thumbs/", blank=True, null=True)

    def image_(self):
        return '<a href="/media/{0}"><img src="/media/{0}"></a>'.format(self.thumbnail)
    image_.allow_tags = True



class AdminName(admin.ModelAdmin):
    .........
    list_display = ('image_',)
