[Rails] mongodb app demo

Hi,

Can any body help me to prepare a small demo of mongoid oriented
application that will
hold contacts details of person.

1.CRUD operation on contacts using scaffold.

Fields
a) Name of preson-> String
b) Phone->will split in two part(i m not sure abt how it work but here need
to initialize a object that will take care of this)[it is one of prominent
feature of mongodb]
-Country Code->String
-Number->String
c)Email(will multiple) ->Array
d)Address(will Multiple)-> but wanted to store in other table named as
"address" will hold field "details"

I am going through google but not getting expected support.

Every day i use to stretch my hair when ever coming around this mongodb
feature.
