The Ruby Reflector

If you prefer a Railscast style video, you can also watch this video which is just a walk through of the getting started guide above.

I recommend following through with the entire getting started guide. I initially wanted to just use chef-solo, which seemed to make more sense, but it turns out it doesn't because you miss out on all kinds of cool features.

I advise against adding a bunch of cookbooks to your chef-repo early on, since there are weird dependencies and other issues …

Having using Acl9 for some time, it was refreshing to see RailsCast's Ryan Bate's take on authorization: CanCan . Ryan put together a webcast for CanCan that you can checkout here . There have been some nice additons since this initial release so do checkout the latest documentation on GitHub. I won't go into what I dislike about Acl9. It's a good system, with a nice DSL for defining permissions. I'll just talk about some of the things …

…hitch -m command. If you setup gravatars for all your devs+user1+user2@company.com email addresses then you'll get a nice picture in Github too.

I think that's about it really. We obviously just install gems as required and make customisations on a per developer need. We generally use Textmate for editing so this means installing a theme (we use the Railscast theme) and the relevant bundles for Rspec, Haml and Sass.

Thanks to a tip by Railscast's Ryan Bates , there's a pretty slick way to refer to, and combine, scope logic: the merge method, aliased as ‘&' . Let's look at how we can use scope#& to refer to the query logic of the Post.published scope from within our User.published scope:

Ruby - user.rb

class User ActiveRecord :: Base scope :published , lambda { joins ( :posts ) . group ( " users.id" ) & Post . published } end
