Paperclip attachment file size
How do I fetch the file size of each style of a paperclip attachment? @user.attachment_file_size doesn't seem to work @user.attachment(:style).size gives a number not related to the actual file size I didn't find either how to get the file size for a given style , other than the original one. As seen in the paperclip source code , @user.attachment.size returns the size of the file as originally assigned. There is no way to get it for a specific style... A solution would be: open(@user.attachment(:style)).size But not efficient at all. To do it well, you should probably add some "custom size"
