Active Record like functionality on array instance variable
- by rube_noob
I would like to write a module that provides active record like functionality on an array instance variable.
Examples of its use would be
x = Container.new
x.include(ContainerModule)
x.elements << Element.new
x.elements.find id
module ContainerModule
def initialize(*args)
@elements = []
class << @elements
def <<(element)
#do something with the Container...
super(element)
end
def find(id)
#find an element using the Container's id
self
#=> #<Array..> but I need #<Container..>
end
end
super(*args)
end
end
The problem is that I need the Container object within these methods. Any reference to self will return the Array, not the Container object.
Is there any way to do this?
Thanks!
