Rails - Jul 2005 - Agile BetaBook3 = stuck because p.103 != p.498

hi all,
after learning happily/smoothly with this agile betabook (from beta 1 
''till 3 like now) with errors here and there but that was no problem, 
now i''m stuck in def save_order :((

Both examples give me errors after i clicked on checkout button (or 
submit) it doesn''t show me every fields fails validation effects
however
i got


  NameError in Store#save_order

undefined local variable or method `find_cart'' for
#<StoreController:0x3c22c08>

|app/controllers/store_controller.rb:38:in `save_order''|


but if i comment line2 (@cart = find_cart) then i got this error:


  NoMethodError in Store#save_order

undefined method `items'' for nil:NilClass

|app/controllers/store_controller.rb:40:in `save_order''
C:/rails/depot/script/server:48|

oh and about footnote number 3 on page 104, my def save_order is _not_ 
after private declaration. so i think my problem''s not here (def 
save_order is before private).

FROM BOOK . PAGE 103

Line 1 def save_order
- @cart = find_cart
- @order = Order.new(params[:order])
- @order.line_items << @cart.items
5 if @order.save
- @cart.empty!
- redirect_to_index(''Thank you for your order.'')
- else
- render(:action => ''checkout'')
10 end
- end


FROM SOURCE CODE - APPENDICES - PAGE 498

def checkout
  # Loosing this line : @cart = find_cart
  @items = @cart.items
  if @items.empty?
    redirect_to_index("There''s nothing in your cart!")
  else
    @order = Order.new
  end
end

million thanks for enlightenment.

Do you have a method called find_cart?

It was introduced in beta3 when I tidied that code up a bit

i didn''t .. but after i added that find_cart method (from source code 
page) after private (without removing cart method before it), now after 
i clicked checkout i got this error (eventhough i do have checkout.rhtml 
in my views )


  ActionView::ActionViewError in Store#save_order

No rhtml, rxml, or delegate template found for actioncheckout

|app/controllers/store_controller.rb:45:in `save_order''
C:/rails/depot/script/server:48|

what''s wrong?

hmm.. seems i gotta rebuild my depot from the beginning according to 
this new betabook3 eh? but that''ll be no problem at all i guess.. this 
repeatition''s making me know rails very well :)

BTW i rebuild it on my Debian platform but i''m still working on it. and
FYI if u don''t mind i also uploaded my depot source code (with 
ActionViewError above) (if u mind, then i''ll remove it due to your 
copyright). anyone of you could see it (and [i hope] could point me to 
what errors i''ve made) at http://www.riyari.com/files/depot.zip

Thank you very much for your reply mr dave.

You''re using an old version of Rails. The book needs 0.13 (which should
be released today or tomorrow).

To be honest I''d rather you didn''t post a modified version,
simply
because I can see it getting very confusing.

It''s my sincere belief that the application in the book runs against 
the latest version of Rails--I run it regularly while building the book 
:)

Once you get the latest Rails, I think you''ll find everything works 
fine.

i just did gem list --remote
and today rails is still 0.12.1

is there a good wiki or an easy howto to install rails 0.13 ? or will 
there be a good explanation (as easy as how to install rails from p.19 - 
p.21) of how to install _the newest rails_ on (at least) Win, Linux, and 
mac os x ? i was searching the archives, googling, but i couldn''t find 
an easy way to this problem (like installing beta gem maybe then the 
newest rails or something else).

i just want to anticipate when agile book uses rails 1.0 at its final 
release so that i''ll be ready to follow it. :)

TIA

# many people criticize many things in ''net

The instructions on http://download.rubyonrails.com/ works for me.

I was told that 0.13 will be released on the 5th.
