Ruby on rails. How to format errors.full_messages?

[Akvarel]

I have such validation structures:

    validates :upload_file_name,  :presence   => true,

                                  :format     =>{:with => %r{\.(jpg)$}i,:message =>"should have an extension .jpg"}

                                    

    validates_uniqueness_of :upload_file_name, :message => "is already in the database"

And when I type in rails console and i get the following answer

     > s.errors.full_messages

    

     => ["Upload file name is already in the database"] 

I need the message to be only "is already in the database" without "Upload file name"

How can I do it? This second solution of this problem did not help me as I get an error:

    en:

      activerecord:

    errors:

    full_messages:

    format:"%{attribute} %{message}"

    

    1.9.3-p286 :002 > s.save()

       (0.2ms)  begin transaction

      Upload Exists (0.3ms)  SELECT 1 AS one FROM "uploads" WHERE "uploads"."upload_file_name" = 'Katja.jpg' LIMIT 1

       (0.3ms)  rollback transaction

    Psych::SyntaxError: (/home/katja/Desktop/tors-jquery-fileupload-rails-paperclip-example-b0b9934/config/locales/en.yml): found character that cannot start any token while scanning for the next token at line 6 column 1

I know this is a super late reply, but for anyone else stumbling across this question: looks like the problem here is that psych is choking on the tab characters, which are not valid yaml. You need to use spaces for indentation.
