Rails Tutorial - I'm having a problem

Curt Hibbs

I'm stuck on step six of the rails tutorial:
http://www.rubyonrails.org/show/Tutor...

After I follow the steps to add phone numbers and update template to display
them, I browse to http://127.0.0.1/frien... and I get the following
error displayed in the browser:

> NameError in Friends#display
> Showing /friends/display.rhtml where line #8 raised uninitialized
constant Person::Phone
> 5: <p>
> 6: <%= @person.name %><br />
> 7:
> 8: <% for phone in @person.phones %>
> 9: <%= phone.phone %><br/>
> 10: <% end %>
> 11:

>
c:/ruby/lib/ruby/gems/1.8/gems/actionpack-0.8.5/lib/action_view/abstract_tem
plate.rb:34:in `render_file'
[snip]

Does anyone know why this is, and what I did wrong?

Thanks,
Curt

You have to add

require 'phone'

somewhere, for example to your model/person.rb file.

Cheers,
Kent.

Duh!!!

I was just blindly following the tutorial (which I think omitted this).
Thanks! I'll go update the tutorial as well.
