sorl-缩略图不起作用

Question

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。我按照说明安装了它。

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 %}

视图：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))

感谢 sorl 我现在终于可以看到问题所在了。这似乎是错误： 请在此处查看完整错误：http://pastebin.com/0Yddt10N

Answer 1

我不知道您的视图代码，但第一个模板代码看起来是正确的。尝试在设置中设置 THUMBNAIL_DEBUG = True 和 DEBUG = True 以进行正常回溯。

Answer 2

尝试：

<img src="{{ im }}" width="{{ im.width }}" height="{{ im.height }}">

Answer 3

确保您使用的是最新的 10.12 版本而不是 3.2.5 版本，因为您的语法属于新的 10.12 版本。

Answer 4

当您将 sorl-thumbnail 添加到 installed_apps 后未执行迁移命令时，就会发生这种情况。

只需尝试python manage.py migrate。
