django - 唯一的缩略图不起作用

Question

我已经尝试了几个小时才能使缩略图正常工作，但是它根本无法正常工作。

困难的部分是它没有显示错误，所以我不知道怎么了。我按照说明进行安装。

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 %}

查看: https://github.com/samos123/Samos-IT/blob/master/samosit/projects/views.py

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))

多亏了 sorl，我现在终于可以看到问题所在了。这似乎是错误:

我不知道您的 View 代码，但是第一个模板代码看起来正确。尝试在您的设置中设置THUMBNAIL_DEBUG = True和DEBUG = True进行正常的追溯。
