在 Django 中指定带有简单缩略图的文件名后缀

Specify a filename suffix with easy-thumbnails in django

我正在使用 django 中的 easy-thumbnails 库来创建缩略图。但是,我不知道如何覆盖缩略图命名过程。目前 lib 将缩略图大小附加到文件名,但我想指定一个自定义名称,例如_大。请问这怎么办?

您可以定义自己的 thumbnail-processor 并在此处作为最后一行:http://easy-thumbnails.readthedocs.org/en/latest/ref/settings/#easy_thumbnails.conf.Settings.THUMBNAIL_PROCESSORS

THUMBNAIL_PROCESSORS = (
   'easy_thumbnails.processors.colorspace',
   'easy_thumbnails.processors.autocrop',
   'easy_thumbnails.processors.scale_and_crop',
   'easy_thumbnails.processors.filters',
   'easy_thumbnails.processors.background',
   'yourProject.thumbnail_processors.renaming', #<---- your custom one 
)

您的处理器文件 (yourProject/thumbnail_processors.py) 看起来像:

def renaming(image, bang=False, **kwargs):
    """
    rename the filename here and just return the image
    """
    return image

虽然没有测试

django-easy-thumbnails 使用 default renaming function. You can write your own naming function and set it in settings as a default naming function the library should use, as described here THUMBNAIL_NAMER:

myapp.utils

def namer(thumbnailer, prepared_options, source_filename,
          thumbnail_extension, **kwargs):
   # do something and return name
   pass

settings.py

THUMBNAIL_NAMER = 'myapp.utils.namer'
