rails - Paperclip file name

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

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! ;)

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

Paperclip attachment has the 'original_filename' method for this.

Use [`File.basename`][1] with the optional `suffix` argument like this:

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

Works on my machine:
