"Any" : order.category I am about to extend the try method to handle this idiom. category = order.try(:category, :on_nill => "Any") # OR category = order.try(:category, :o...

Hello all, I'm not a Ruby programmer, but as I was reading through the extensive RoR security guide I noticed this section: http://guides.rubyonrails.org/security.html#regular-expressions A common pitfall in Ruby’s regular expressions is to match the string’s beginning and end by ^ and $, instead of \A and \z.

Oddly enough, this fails the assertion, beca...

If I run: rake sunspot:reindex, then everything works as expected. ...
I am about to embark on a project which will be a database with potentially thousands of entries. It is for an Australian audience so load should not be particularly high. The developer who is interested has a strong preference for RoR. However I am unconvinced of the benefits of RoR for all aspects of a project. For example, while RoR...

OK, I am trying to understand the best practices for the CREATE and UPDATE methods for both HTML and XML formats. The default code for a controller that the rails generator generates is a little unclear to me. For the CREATE method, given a good save, the generator says to "redirect_to(@whatever)" for HTML and "render :xml => @whatever...
