1
00:00:00,960 --> 00:00:04,750
We'll end our tour of the rails
console with the delete operations.

2
00:00:04,750 --> 00:00:07,660
Your users need to be able
to delete data as well so

3
00:00:07,660 --> 00:00:11,050
rails also allows the removal
of records from the database.

4
00:00:11,050 --> 00:00:14,440
We just load up a particular
instance of the model as before and

5
00:00:14,440 --> 00:00:17,210
then call the destroy-method on it.

6
00:00:17,210 --> 00:00:19,450
Let's get a list of all
the post objects again.

7
00:00:22,070 --> 00:00:28,620
And let's load a particular instance
using its ID and assign it to a variable.

8
00:00:28,620 --> 00:00:34,199
Post equals post.find (4).

9
00:00:34,199 --> 00:00:37,890
Now we'll call the destroy
method on that object,

10
00:00:37,890 --> 00:00:42,190
post, lower case because it's
a variable named destroy.

11
00:00:44,940 --> 00:00:48,360
We'll see an SQL query that deletes
the record from the database.

12
00:00:49,520 --> 00:00:52,300
Note that the method name
is destroy not delete.

13
00:00:52,300 --> 00:00:53,980
A method called delete exists, but

14
00:00:53,980 --> 00:00:57,220
it works in different and
potentially confusing ways.

15
00:00:57,220 --> 00:01:00,180
You'll want the destroy
method in most cases.

16
00:01:00,180 --> 00:01:01,680
If we call post at all again,

17
00:01:03,400 --> 00:01:07,180
we'll see that the record we destroyed
is gone from the collection.

18
00:01:07,180 --> 00:01:10,300
That wraps up our two of
the rails console for now.

19
00:01:10,300 --> 00:01:13,900
Before we can run bin rails generator
other commands we need to exit

20
00:01:13,900 --> 00:01:15,320
the console program.

21
00:01:15,320 --> 00:01:17,670
Type exit all by itself on a line and

22
00:01:17,670 --> 00:01:20,020
press enter and
you'll be back to your system prompt.
