[MUSIC]

2
00:00:04,750 --> 00:00:08,608
We've seen how to use the web
interface to create new model objects.

3
00:00:08,608 --> 00:00:12,850
Now I wanna show you how to do the same
from the terminal using the Rails console.

4
00:00:12,850 --> 00:00:16,800
The Rails console is useful when you need
to do an operation on many model objects

5
00:00:16,800 --> 00:00:20,520
at once, or to look at model attributes
that you haven't yet added to your views.

6
00:00:21,810 --> 00:00:25,490
We've seen the Rails server and
generate sub commands already.

7
00:00:25,490 --> 00:00:27,730
Console is another sub command.

8
00:00:27,730 --> 00:00:29,830
So let's make sure the Rails
server is stopped and

9
00:00:29,830 --> 00:00:31,700
we're back at our system prompt.

10
00:00:31,700 --> 00:00:35,670
Then we type bin/ rails
console in our terminal.

11
00:00:37,100 --> 00:00:40,770
You'll leave your system prompt and
be taken to a prompt provided by Ruby.

12
00:00:40,770 --> 00:00:42,870
Here you can type Ruby expressions.

13
00:00:42,870 --> 00:00:45,520
They'll be evaluated and
you'll be shown the result.

14
00:00:45,520 --> 00:00:49,560
If you've used Ruby's IRB command before,
it works just the same way.

15
00:00:49,560 --> 00:00:52,370
The difference is you have your
full Rails environment loaded,

16
00:00:52,370 --> 00:00:54,410
including your model classes.

17
00:00:54,410 --> 00:00:56,720
Your model class is connected
to your database so

18
00:00:56,720 --> 00:01:00,450
you can create, read, update,
or delete model data.

19
00:01:00,450 --> 00:01:03,880
Let's try out all the cred operations
using our post model class.
