'WSGIRequest' 对象在添加 easy_thumbnails context_porcessors 后没有属性 'mode'

Question

我试图在我的 settings.py 中添加 easy_thumbnails 上下文处理器并得到下一个错误：

WSGIRequest'对象没有属性'mode'

上下文处理器配置：

TEMPLATES = [
    {
        ....
    'OPTIONS': {
    'context_processors': [
        ....
                'easy_thumbnails.processors.colorspace',
                'easy_thumbnails.processors.autocrop',
                'filer.thumbnail_processors.scale_and_crop_with_subject_location',
                'easy_thumbnails.processors.filters',
            ],
        },
    },
]

是的，我使用的是最新版本的 Pillow 和 easy_thumbnails。

我弄错了，抱歉。这不是上下文处理器，而是缩略图处理器。我只是添加：

THUMBNAIL_PROCESSORS = (
    'easy_thumbnails.processors.colorspace',
    'easy_thumbnails.processors.autocrop',
    'easy_thumbnails.processors.filters',       
    'filer.thumbnail_processors.scale_and_crop_with_subject_location',
)

现在一切正常。
