Hello guys, i’m new in ruby and i’m trying to create an Address Book.  
(I’m from Brasil)  
When i put the book to print  
“puts lista” #lista is the Address Book  
the method to\_s of the AddresBook class is like this:  
"def to\_s  
puts “Lista Telefonica”  
puts "Numero de Contatos: " + @qtContatos.to\_s  
@persons.each do |pessoa|  
#persons is an array of a Class Person that have it’s own to\_s method  
puts pessoa  
puts “”  
end  
end  
"

It’s working well, but when I run it in the cmd:  
“C:\Users\Dudu.gem\exe\>ruby ListaTelefonica.rb”  
(I’m using Windows 7 with Gems version “1.3.5”)

The print Returns the & (address) of each thing I print…  
example:  
"  
Nome: My Name  
Email: removed\_email\_address@domain.invalid  
Fone: XXXXXXX  
Endereco:  
Rua NumSei, 321  
Cidade: Anyone  
Pais: Brasil  
#Address:0x2803ae0  
#Pessoa:0x2803b20

#AddressBook:0x28043a0  
"

How can I take this Address out??  
this “#AddressBook:0x28043a0” and the others  
:S  
Thanks!!!

First of all, method to\_s() should _return_ a string, not print it. So,  
remove puts() from to\_s() and simply return a string. In your case,  
return from to\_s() is the content of your @persons array, it gets  
printed by your “puts lista” statement.

You can do something like the following:

def to\_s  
[  
“Lista Telefonica”,  
“Numero de Contatos: #{@qtContatos}”,  
@persons.map { |pessoa|  
pessoa.to\_s  
}  
].join("\n")  
end

Then, if to\_s() for objects in your @persons array is defined  
accordingly, you should have a nice looking output.

Gennady.
