This method does something like this: "update model_table_name set counter_column = counter_column + 1 where id = 'your row id' " So, it's up to your database (and the isolation level that it's using) to handle the atomicity of this call. Put simply, it will usually work, unless your database has some serious concurrency issues. -- Maurício Linhares http://alinhavado.wordpress.com/ (pt-br) | http://blog.codevader.com/ (en) João Pessoa, PB, +55 83 8867-7208 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
