Sequel getting better

I've been trying to get sequel work with dataset methods from module. It's not such an obvious thing, as the dataset methods are defined

def dataset.some_method(args)
  # method here
end

which makes it impossible to do it the _classic_ ruby-module way. Jeremy Eveans (Sequel's creator) enlightened me ;) on the #sequel channel. The Plugin architecture provided by Sequel::Model::is method is the way to do it!

So basically it's

module Sequel::Plugins::Bunchy
  module DatasetMethods
    # define dataset methods here
  end

class ShinyModel < Sequel::Model
  is :bunchy
end

You define a module inside Sequel::Plugins scope and inside it define special modules which keep the methods.

• InstanceMethods


• ClassMethods


• DatasetMethods

Names are self-explaining. For some more info go http://sequel.rubyforge.org/classes/Sequel/Plugins.html

Also, after a short chat with Jeremy he told that Sequel is going to have built-in support for separate read and write connections! This means that SELECT will use different DB than INSERT/UPDATE/DELETE. Seems very handy in web apps to lower the DB load on each request. Keep up the good work!
