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

Im doing this to strip whitespaces:

before_post_process :transliterate_file_name

private
def transliterate_file_name
  self.instance_variable_get(:@_paperclip_attachments).keys.each do |attachment|
    attachment_file_name = (attachment.to_s + '_file_name').to_sym
    if self.send(attachment_file_name)
      self.send(attachment).instance_write(:file_name, self.send(attachment_file_name).gsub(/ /,'_'))
    end
  end
end

I hope this will help you.

edit:

In your example:

def basename
  self.image_file_name = "foobar"
end

Should do the job. (but might rename the method ;) )
