Question

我想在模板中将上传的图像显示为缩略图。我在已安装的应用程序中安装了sorl-thumbnail。当我执行我的应用程序时，我得到一个模板错误，如下所示：

语法错误。预期：thumbnail source geometry [key1=val1 key2=val2...] as var 异常位置：/usr/local/lib/python2.7/dist-packages/sorl_thumbnail-11.12 py2.7.egg / sorl / thumbnail / templatetags / thumbnail.py在 init ，第65行

请帮我找到解决方案。我的代码如下

class Photo(models.Model):
   image = models.ImageField(upload_to='/home/forent/sites1/dreamaddress/media/uploads/properties/image')
   tag=models.CharField(max_length=255, null=True,blank=True)
   caption=models.CharField(max_length=755, null=True,blank=True)
   prop=models.ForeignKey(Property,blank=True,null=True)

查看：

def img_all(request):
    imgs = Photo.objects.all()
    return render_to_response('details.html',{'imgs':imgs},context_instance=RequestContext(request))

  {% endfor %}
</div>

Answer 1

Look at the example in the docs

您需要引用几何值：

<img src="{% thumbnail img.image '480x312' crop="center" quality="90" %}" alt="">

以缩略图形式显示图像
