[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.

has_many brings back ''uninitialized constant''
hello. first things first - I am new to ruby on rails (ruby, too), so I''m figuring this is just a basic newbie error. I''m creating a basic photography website.

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 :-) -- Posted via http://www.ruby-forum.com/.

usage of constants
I would like to define some constants that I can use across models and views and I cannot figure out how to do that. Googling hasn''t turned up anything useful and I''m looking at the PickAxe book, and I get the impression that a constant must belong to a class. If I just want a constant like... CompanyPhoneNo = "(602) 999-9999" and be able to use it in any view

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 if !

:conditions => ["phone like ''%:phone%''" , {:phone => "555"}]
Hi all, What''s wrong with the way I specify the condition in : Person.find :all, :conditions => ["phone like ''%:phone%''" , {:phone => "555"}] ? It translates to (note the two '' between the two ") SELECT * FROM people WHERE (phone like "%''555''%" ) instead of SELECT * FROM people WHERE
