Agile Web Developement with Rails
I recently got a copy of the second addition in PDF
and got stuck on the Ajax portion using highlighting
page 128. While trying to make my cart flash I got an
RJS error when I click add to cart. I have gone back

no help. I sent Dave an email and he rec''d this list.
Anybody got any good links for troubleshooting Ajax or

examples in the second edition Agile book. I have everything working

ERb on he command line re: Ruby For Rails book

When I add an item to the shopping cart, I get an error:
undefined local variable or method `cart_item'' for

Agile Web Dev (book) question: errors
This is kind of frustrating (but no doubt helpful in the long run) that
after following along and coding , and d/l the code the same error is
appearing.
For those who are familiar with the depot app, I''ve run into a problem after
fixing the cart to reflect quanitites. I worked through the intended error
messages but now have this appearing:

[ANN/ADV] Ruby for Rails now published in paper!
Hi --
I''m on the road, so I haven''t laid eyes on it yet -- but word on the
virtual street is that "Ruby for Rails: Ruby techniques for Rails
developers" is now out in paper.
It will probably take a little longer to trickle to your neighborhood
Barnes and Noble... but you can order it now from the publisher. See
http://www.manning.com/black. And trickle it will, too.

How to render from with <%%> ?
I have a loop that I iterate through in my view.
<%
coll.each do |itm|
puts(itm.value)
end
%>
How do I render the itm.value without using a <%= %> tag? Should puts
not work?
Joerg
P.S. There is a good enough reason for me wanting to do this :-)

Passing function names from string variables
This may be a more generic Ruby question, so I''m going to ask on the Ruby
forum, but I''m trying to figure out if there is a way to pass in the string
value of a variable as the name of a method.
For example, I would like to do something like:
def sort_obj_by_uid(objects,@attr)
@tmparray = Array.new
@tmphash = Hash.new
for object in @objects
