Rails - Jan 2007 - error_message_on broken?

Hi,

in my app, using the error_message_on form helper like this:


<label for="user_name">User name:</label>
<%= error_message_on ''user'', :name %>
<%= f.text_field :name %>

generates the following error:

undefined method `errors'' for :user:Symbol

I am using edge revision 5813 and the simply_helpful plugin. Is there a
way to fix this?

Ingo

Hi,

The problem is in active_record_helper.rb, in the method 
error_message_on replace for the old code:

def error_message_on(object, method, prepend_text = "", append_text = 
"", css_class = "formError")
        #if object = instance_variable_get("@#{object}") &&
errors =
object.errors.on(method)
        #  content_tag("div",
"#{prepend_text}#{errors.is_a?(Array) ?
errors.first : errors}#{append_text}", :class => css_class)
        #else
        #  ''''
        #end
        if errors =
instance_variable_get("@#{object}").errors.on(method)
          content_tag("div",
"#{prepend_text}#{errors.is_a?(Array) ?
errors.first : errors}#{append_text}", :class => css_class)
        else
           ''''
        end
      end
