在使用CarrierWave gem将附件上传到Amazon S3的Rails 5中,如何在成功将图像上传到S3后让CarrierWave删除图像的本地副本?
答案 0 :(得分:2)
如果您的/ tmp目录充满了机架tmp上传垃圾,您可以在回调中将其删除,如下所示:查看here
class FileUploader < CarrierWave::Uploader::Base
after :store, :delete_old_tmp_file
# remember the tmp file
def cache!(new_file)
super
@old_tmp_file = new_file
end
def delete_old_tmp_file(dummy)
@old_tmp_file.try :delete
end
end
