Action Controller: Exception caught

Hello,

I am trying to this project to work but I ran into this issue, the
project is from a book called Beginning Ruby on Rails E-Commerce: From
Novice to Professional. It references stuff from Rails 1.0. I am still
new at using Ruby and Rails. Thanks for any help.

NoMethodError in Admin/author#new

Showing C:/IS410/Programs/emporium/app/views/admin/author/_form.html.erb
where line #1 raised:

undefined method `error_messages_for’ for
#<#Class:0x40f6d10:0x45784e0>

Extracted source (around line #1):

Error messages for was removed in rails 3. It was extracted to a plugin,
don’t remember exactly what the plugin was called but it’s in the rails
GitHub repo. Rails has changed massively since 1.0 - I really would try
and find some more up to date material to work from.

Fred.
