验证是否存在无法在Rails 2.3.8中工作的情况

Question

I have a simple Rails app that has a model that is contained in several places. I allow the updating of the model from several different controllers in Rails 2.3.8. In my model I have code that allows for the name and the description to be validated. If they are blank Active_Scaffold should be populating the div with an error message. This works in the page that is linked directly to the User's controller but if I include the user anywhere else it will only show up on the User's controller page and not on the page that they are currently on. Shouldn't Acitive_Scaffold magically redirect to the correct place?

Code:

class User < ActiveRecord::Base
    validates_presence_of :name, :description, :allow_blank => false

    def create_from_params(params)
        @name = params[:name]
        @description = params[:description]
    end

As you can see nothing spectacularly hard.

EDIT: Sorry I left out the rest of the method signature

Answer 1

I suspect the active_scaffold views only check for errors on the model it represents. Add this error check code to any view but the user view.

<%= error_messages_for :user %>
