rails how to display data or retrieve values after find -

i did find on model , got following

>> @addy => [#<address id: 3, street: "some street", housenumber: nil, created_at: "2010-01-20 06:09:52", updated_at: "2010-01-20 06:09:52", address_id: 16>] 

now how retrieve values? if want street?

@addy.street not work netiher @addy[:street]

what if had list of @addy's , wanted loop through them show street each?

@addy.first.street should work, list of adress classes containing 1 member.

for displaying each street more adresses in list:

@addy.each |address|   puts address.street end 

or

list_of_streets = @addy.map { |address| address.street } 

edit:
when have problem identifying class have, check object.class. when use object in irb, see output object.inspect, doesn't have show class name or can spoof informations. can call object.methods, object.public_methods.

and remember in ruby class instance (of class class). can call @addr.methods instance methods , @addr.class.methods class methods.

edit2:
in rails #find can take first parameter symbol, , if pass :first of :last, you'll 1 object. same if pass 1 integer (id of retrieved object). in other cases list result, if contains 1 object.
