00:00:00,410 --> 00:00:05,040
Now that we know how to create and send in
attributes when working on a class,

2
00:00:05,040 --> 00:00:09,930
let's go ahead and fix up our name class
with the different name attributes.

3
00:00:11,450 --> 00:00:13,830
Now this pattern that we see right here,

4
00:00:13,830 --> 00:00:19,620
where we are setting instance variables,
and then calling them later.

5
00:00:19,620 --> 00:00:22,240
It's something that's done quite a bit in
Ruby.

6
00:00:22,240 --> 00:00:27,150
And Ruby actually gives us a shortcut for
doing this exact thing.

7
00:00:28,420 --> 00:00:35,990
The shortcut is using a method called
attr_reader which stands for

8
00:00:35,990 --> 00:00:37,860
attribute reader.

9
00:00:37,860 --> 00:00:39,020
Now let's try it right here.

10
00:00:41,000 --> 00:00:44,210
When we set the attribute reader as a
title,

11
00:00:45,680 --> 00:00:49,100
we can go down to the Title Method and
take this out.

12
00:00:50,830 --> 00:00:54,510
Now, if we run this program again, we
should see the same thing printed.

13
00:00:57,030 --> 00:00:58,560
And we do.

14
00:00:58,560 --> 00:01:01,650
When we call the Adder Reader Method.

15
00:01:01,650 --> 00:01:05,760
Ruby is actually writing this method for
us.

16
00:01:05,760 --> 00:01:07,680
It takes the name that we send in.

17
00:01:07,680 --> 00:01:08,910
Which in this case is title.

18
00:01:10,340 --> 00:01:13,830
And actually creates this method.

19
00:01:13,830 --> 00:01:16,410
Which just returns the variable.

20
00:01:18,500 --> 00:01:23,690
So we can go ahead and do that for all of
our different named attributes.

21
00:01:33,260 --> 00:01:35,110
Now our class just looks like this.

22
00:01:37,870 --> 00:01:38,510
And let's go ahead and

23
00:01:38,510 --> 00:01:42,070
run it and just make sure that everything
is printed out the same way again.

24
00:01:43,280 --> 00:01:45,910
And it works exactly as we expect it to.
