Our address book functionality is getting there. In this video, we implement the ability to add contacts via the command line.
Code Samples
def add_contact
contact = Contact.new
print "First name: "
contact.first_name = gets.chomp
print "Middle name: "
contact.middle_name = gets.chomp
print "Last name: "
contact.last_name = gets.chomp
loop do
puts "Add phone number or address? "
puts "p: Add phone number"
puts "a: Add address"
puts "(Any other key to go back)"
response = gets.chomp.downcase
case response
when 'p'
phone = PhoneNumber.new
print "Phone number kind (Home, Work, etc): "
phone.kind = gets.chomp
print "Number: "
phone.number = gets.chomp
contact.phone_numbers.push(phone)
when 'a'
address = Address.new
print "Address Kind (Home, Work, etc): "
address.kind = gets.chomp
print "Address line 1: "
address.street_1 = gets.chomp
print "Address line 2: "
address.street_2 = gets.chomp
print "City: "
address.city = gets.chomp
print "State: "
address.state = gets.chomp
print "Postal Code: "
address.postal_code = gets.chomp
contact.addresses.push(address)
else
print "\n"
break
end
end
contacts.push(contact)
end

So, when we just left off,
we had added the ability to add a contact
0:00
to append to the internal contacts array.
0:06
Now, what we're gonna do is add
the ability to add addresses and
0:08
phone numbers to this
contact when we add them.
0:13
So, we're gonna do that right here and
we're gonna do this using another loop.
0:17
So we'll say loop do and end.
0:22
So now we'll just display another menu, so
0:27
when we add this contact we'll
say add phone number or address.
0:31
And then we can use the letter
p to add a phone number
0:38
and a to add an address.
0:44
And then we will ask for a response.
0:52
And make it lowercase.
0:57
And now we have our response case method.
1:02
Now what do we do when we have a response?
1:08
Well, when it's the letter p,
we'll add a phone number,
1:10
when it's the letter a we'll add
an address, and if it's anything else,
1:14
we'll go back which will bring
us back into the main menu loop.
1:20
And let's go ahead and
just add a little message for that,
1:25
that says, Any other key to go back.
1:28
Okay, and actually let's go ahead and
print out a new line before we go back.
1:34
All right, so when the letter p happens,
let's go ahead and add a phone number.
1:40
Now, the way that we do this is similar
to how we just added a contact up here.
1:45
First we will initialize a new instance
of the phone number class, and
1:50
then we'll just ask the user for input.
1:56
So it's the letter p.
2:00
We'll say a phone is a new phone number.
2:01
And then we'll print out,
2:09
what kind of phone number is it,
Home, work etc.
2:12
And then the kind of phone number
is standard input once again.
2:21
And now that we have the kind we'll
ask them to input the number.
2:28
And then we can append
2:35
this phone number.
2:41
And that should bring us back to
the menu with the option to add
2:47
another phone number or an address.
2:51
And so adding the address is going
to follow the exact same pattern.
2:55
So I'm just gonna go ahead and
paste that in here.
3:01
So we initialize a new address instance,
ask what kind it is,
3:09
allow them to enter all of
the address information.
3:13
I'm gonna append it to
the internal addresses array.
3:17
At the end of all this, it will be
pushed on to the contacts array.
3:22
So now, let's go ahead and
run this and see how it's looking.
3:28
Go ahead and type in ruby Address_book.rb.
3:32
Let's go ahead and
just print the address book.
3:36
Okay, there's no one in the contact list.
3:40
Oh, the choice is not one,
it is a to add a contact,
3:44
Jason, middle name no middle name,
last name Seifer.
3:47
Do I wanna add a phone number or
an address?
3:51
Yeah, I think I'd like
to add a phone number.
3:53
Home phone number, 123-456-7890.
3:57
That is my actual phone number.
4:02
Please do not call me.
4:03
Okay, and let me add an address too.
4:05
Add a home address, 123 Home Address.
4:08
And that's in Orlando, Florida.
4:15
Postal code is 12345.
4:20
Okay, that seems to be working.
4:22
Let's go back.
4:24
Let's go ahead and print the address
book and see how it looks.
4:25
All right, got the contact list,
with Jason Seifer, looks good.
4:28
So I can go ahead and press e to exit and
next up we'll add the ability to search.
