In my users_contoller.rb I have, def create @user = User.new(params[:user]) # Handle a successful save. if @user.save redirect_to @user else @title = "Sign up" render 'new' end end At that time the validates in the model user.rb gets triggered, am I correct to say that. It validates the fields based on the code like validates :uun, :presence => true, length => { :maximum =>12}, :uniqueness => true validates :uname, :presence => true, length => { :maximum => 64} etc... after this I use puts "the name is #{uname}". This has problem. But if I do the puts in "before_save :encryt_password". Then I have no errors. I just want to add some more fields before saving the record, that's why it is important for me. So, if I know in which variable validates gets the value, might be I can also use it in the same manner. Thanks & Regards, Bhasker.
