Rails style models?

[xmitchx]

Hi,

I was just wondering how rails makes the attributes of a model part of the model class like:

User.username =

How do you get that username= method dynamically generated?

Thanks

It uses a method_missing hack to dynamically generate the getters and setters for your db tables. You can get similar behavior from your pure ruby classes using the following technique:

class Foo
  attr_accessor :bar
  attr_accessor :qux
end

a = Foo.new
a.bar = "test"
a.qux = "another test"

puts a.bar
puts a.qux
