Paperclip how to change basename (filename)?

Question

I am trying to change the basename (filename) of photos:

In my model I have:

  attr_accessor :image_url, :basename

  has_attached_file :image,
                  


        

Answer 1

I wanted to avoid having to add a before_create callback to every model with an attachment. I had a look at the source and at the time of this writing it looked sth like:

module Paperclip
  class Attachment
  ...
    def assign_file_information
      instance_write(:file_name, cleanup_filename(@file.original_filename))
      instance_write(:content_type, @file.content_type.to_s.strip)
      instance_write(:file_size, @file.size)
     end

So you could just patch cleanup_filename.

config/initializers/paperclip.rb

module Paperclip
 class Attachment
   def cleanup_filename(filename)
     "HALLLO"
   end
  end
 end
