rails - Paperclip file name
提问by AnApprentice
using rails with Paperclip, I can use the following to get the filename during a before_create:
将 rails 与 Paperclip 一起使用，我可以使用以下内容在 before_create 期间获取文件名：
extension = File.extname(photo_file_name).downcase
扩展名 = File.extname(photo_file_name).downcase
How do I get JUST the file name.. Right now I have photo_file_name which provides the entire file, titlename.pdf
我如何获得文件名..现在我有 photo_file_name 提供整个文件，titlename.pdf
i need just titlename without the .pdf

File.basename与可选suffix参数一起使用，如下所示：

Paperclip attachment has the 'original_filename' method for this.
回形针附件为此具有 'original_filename' 方法。

助手/application_helper.rb
def sanitize_filename(filename)
fn = filename.split /(?<=.)\.(?=[^.])(?!.*\.[^.])/m
fn[0] = fn[0].parameterize
return fn.join '.'
end
Create config/initializers/paperclip_defaults.rb

Paperclip.interpolates :parameterize_file_name do |attachment, style|
"#{sanitize_filename(attachment.original_filename)}_www.foo.com"
