我已经尝试过django-filer在单个文件字段中选择多个文件，只是我尝试了我的简单模型，我面临着这个模板错误。我刚刚在django admin中使用了一个简单的模型。 请你帮助我好吗？
class MyFile(models.Model):
title = models.CharField(max_length=200)
cover = FilerFileField(null=True,blank=True)

好像你想使用'easy_thumbnails'https://github.com/SmileyChris/easy-thumbnails 这是django-filer的依赖。
尝试添加您的settings.py，应用：'easy_thumbnails'
看看变量：
THUMBNAIL_PROCESSORS = (
'easy_thumbnails.processors.colorspace',
'easy_thumbnails.processors.autocrop',
#'easy_thumbnails.processors.scale_and_crop',
'filer.thumbnail_processors.scale_and_crop_with_subject_location',
'easy_thumbnails.processors.filters',
)

您似乎忘了将easy_thumbnails添加到INSTALLED_APPS。添加它，运行syncdb然后查看它是否有效。
