Paperclip - rename file before saving

Question

I use this method for renaming the image before the saving:

  def rename_avatar
    self.avatar.instance_write :file_name, Time.now.to_i.to_s
  end

  before         


        

Answer 1

This is the way how I fix my issue:

  def rename_avatar
    #avatar_file_name - important is the first word - avatar - depends on your column in DB table
    extension = File.extname(avatar_file_name).downcase
    self.avatar.instance_write :file_name, "#{Time.now.to_i.to_s}#{extension}"
  end
