Searching the Address Book2:50 with Jason Seifer
In this video, we implement searching on the user facing side of things.
when 's' print "Search term: " search = gets.chomp find_by_name(search) find_by_phone_number(search) find_by_address(search)
Okay, so now that we can add contacts and print them out, let's go ahead and 0:00 add the ability to search. 0:03 So, first we'll add that as a prompt on the menu, we'll say Search. 0:07 And this is going to be pretty easy. 0:15 We just add another menu option in our case statement. 0:18 So when it is the letter s. 0:22 We'll just say enter your search term. 0:27 And then we will grab that from standard input. 0:33 And now, we've got all of the different methods that we wrote earlier, 0:37 to find something. 0:43 So we've got, find my name, find by phone number, and find by address. 0:44 So, since those are already working, let's go ahead and just call those terms. 0:48 With this search variable that we just got from standard input. 0:54 And there we go, and actually at the end of this, okay, we've got a new line. 1:02 Perfect. 1:06 So all we're gonna do, we get this search query from the user, 1:08 and then we call our methods with it. 1:11 And that's it, we already wrote the methods earlier. 1:14 So we're just gonna be calling them here. 1:17 Now, we could get more fancy with it and add each of these as a menu option. 1:19 But I'm just going to assume that when we want to search our contact list, 1:24 we're gonna look through every field. 1:29 So, now let's go down to the console and see how it works. 1:30 Now first let's add a contact to make sure it works. 1:40 Jason Seifer. 1:42 Now add a phone number to my home phone number. 1:45 123-456-7890. 1:49 And then the other key to go back. 1:52 Add another contact. 1:55 Nick Avery Pettit. 1:56 Now add an address. 2:01 Work address. 2:03 Okay, now let's try searching. 2:13 So, let's try searching for Nick. 2:15 All right, search results for Nick. 2:19 Here's Nick Avery Pettit. 2:21 No phone search results and no address search results. 2:24 Let's try searching again, search term is 2. 2:27 And it looks like I came up, Jason Seifer because my phone number has 2 in it. 2:32 And Nick came up, because the address has a two in it. 2:39 Okay. 2:42 That's great. 2:43 In our next video, 2:43 we're going to see how to persist the address book in between sessions. 2:45
