New Rails plugin: IncludeByDefault

It’s true, I’m a plugin writing machine. Seriously though, this one’s tiny. I took all of five minutes to write. What it does is, it lets you specify a default value for the :include option on ActiveRecord::Base.find, so you can automate eager loading of associations. I’ll use an example I’m comfortable with:

  class BlogEntry < < ActiveRecord::Base
    has_many :photos
    has_many :comments
    include_by_default :photos, :comments

With that in place, the photos and comments will automatically be loaded in the same database query as the entry you ask for. You can still use the :include option with find – it will override the defaults you specify. Install as usual:

script/plugin install
