我已经尝试了几个小时来让 sorl-thumbnail 工作，但它就是行不通。
困难的部分是它没有显示错误，所以我不知道出了什么问题。我按照说明安装它。
我的完整代码可以在这里找到：https ://github.com/samos123/Samos-IT/tree/master/samosit
模板：https ://github.com/samos123/Samos-IT/blob/master/samosit/templates/projects/project_detail.html
{% load thumbnail %}
{% thumbnail object.image "100x100" crop="center" as im %}
<img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
{% endthumbnail %}

def detail(request, project_id, slug):
project = get_object_or_404(Project, pk=project_id)
imageurl = "/media/"+project.image.url
return render_to_response('projects/project_detail.html', {'object' : project, 'imageurl' : imageurl}, context_instance=RequestContext(request))
感谢sorl，我现在终于可以看到问题所在了。这似乎是错误：在此处查看完整错误：http: //pastebin.com/0Yddt10N
