@Snuggs: you can use some special key in your options hash, for example:

  should_delegate :category, :to => :post, :args_for_new => [1, 2, 3]

Then use it in the should_delegate method:

  def self.should_delegate *args
     # snip...
     should "delegate #{name} to #{to_class}" do
       args_for_new = opts[:args_for_new] || []
       to = to_class.send(:new, args_for_new)

I hope you get the idea :)

How can you test that an object has arguments or not. This code worked PERFECTLY until I came across one of my objects that needed an argument passed to new :-/

Agree with the above comment. This was really helpful and should be part of the documentation.

Fantastic tutorial. Just what I was looking for. And then you are also a great author. This kind of stuff should be part of the shoulda documentation.
