Subject: Mass Assignment on Clas

Hi there,

I am a total newbie to Ruby, so please bare with me.

I want to be able to be able to initialise a Class with a hash.  For
instance If I have the class

class Vehicle
  attr_accessor :vtype, :description, :vehicle, :capacity
end

I want to be able to do

Vehicle.new(:vtype => 'ECAR', :description => 'Great Car', :vehicle =>
'Ford Focus', :capacity => '10');

Now I could do something like

def initialize(items)
     @vtype = items[:vtype]
     @description = items[:description]
     @vehicle = items[:vehicle]
     @capacity = items[:capacity]
#     puts items.inspect
   end

But I was wondering if there was a more generic way of doing this
without specifically defining each variable in initialize? I think
ActiveRecord does something similar!

Many thanks for your assist!
