rails - Paperclip file name

Question

using rails with Paperclip, I can use the following to get the filename during a before_create:

extension = 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

i need just titlename without the .pdf

Thanks

Updating with code:

photo.rb:

  before_create :obfuscate_file_name

  #Paperclip for photo
  has_attached_file :photo,
......


private

  def obfuscate_file_name
    extension = File.extname(photo_file_name).downcase
    fileNameOnly = File.basename(photo_file_name).downcase
    self.photo.instance_write(:file_name, "#{fileNameOnly}_#{ActiveSupport::SecureRandom.hex(32)}#{extension}")
  end

Answer 1

Use File.basename with the optional suffix argument like this:

file_name = File.basename(photo_file_name, File.extname(photo_file_name));

Works on my machine:

Answer 2

Paperclip附件具有'original_filename'方法。

Answer 3

user.logo.original_filename
  => 'test.jpg'

Answer 4

Another option is set to default, work for all upload.

This example change name file to 'name default' for web, example: test áé.jpg to test_ae_www.foo.com.jpg

helper/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

include ApplicationHelper

Paperclip::Attachment.default_options.update({
    :path => ":rails_root/public/system/:class/:attachment/:id/:style/:parameterize_file_name",
    :url => "/system/:class/:attachment/:id/:style/:parameterize_file_name",
})

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

Need restart, after put this code

I hope it help! ;)
