What would my two VirtualHost entries look like for Apache with Passenger? And in the code, for the first subdomain handling app, so long as I handle th...
How can I send mails in a mailer using the recipient's locale. I have the preferred locale for each user in the database. Notice this is different from the current locale (I18n.locale), as long as the current user doesn't have to be the recipient.

Very often in Rails 3, when I get a deprecation warning, the line reference I get is in the Rails framework instead of the actual deprecated line! For example, I try to save a user model : irb(main):006:0> user.save DEPRECATION WARNING: save(true) is deprecated, please give save(:validate => true) instead. (called from save at /home/...

Guys, I'm trying my best to build a helper that outputs a <'ul> consisting of all the members of a collection. For each member of the collection I want to print out a <'li> that has a title, and a div of links to CRUD the member. This is pretty similar to what Rails outputs for scaffolding for the index view. Here is the helper I've ...
