How do I make this work? I am running Linux (Ubuntu Breezy) Regards, Paul

Hi all, I''d like to add a instance method to class String. I should be fairly simple with class String; def newmethod; do_something ; end; end and it works perfectly if I test this independently with irb. However if I add this to my application.rb I''ll get an error like (undefined method `newmethod'' for "123456":String) What''s wrong with that?

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 !

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
