Just a point that I've always found slightly confusing. If I've understood correctly this line.. if @record.update_attributes(params[:sample]) actually *does* the updating part, believe the if is there for error trapping and returning. I've always struggled as to why that line starts with the word "if", am I reading it right in that the line basically does the update_attributes "if" it can? Maybe I'm just thinking about it wrong but it doesn't seem intuitive to me. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
