Well, this was fun.
0:01
But what we actually want is to have a way
0:03
to browse the guitars.
0:05
So, let's come in here and define one more thing
0:07
and then we'll put our demo app away.
0:11
We want all the guitars
0:13
and it's going to look really similar to this.
0:17
Let's go down here and say we want the guitars to be
0:21
somehow we're going to have to get those guitars
0:23
from somewhere in a moment.
0:25
And we'll just come down here and say this is the guitars
0:28
equal to the guitars. This is our variable.
0:30
This is the data name in the template.
0:33
And this will be guitars.
0:36
We've already added this cool little service
0:38
database thing.
0:39
So I can come over here and say catalog, service.
0:45
Pytrom knows about it and will write the thing
0:47
to us it up at the top
0:48
and then we just say all_guitars.
0:50
That will just say None.
0:52
So, that should return our guitars here.
0:55
And then we can just go and print it out.
0:57
We're going to need this guitar's file
0:59
so let's do that real quick and then we're going to
1:01
get it to be all guitars.
1:14
And each of these guitars has a name and a price
1:17
and so on.
1:18
We're just going to put the name out for just a second.
1:20
Let's see if that works. Go in your saved guitars.
1:28
Oh, whoops! Looks like I forgot to put this part member
1:31
that's required. Here we have it.
1:34
Here are all the guitars! Look how awesome that is!
1:36
Just those few lines, we've gone to the database
1:38
as we've got all these.
1:40
That course is not nearly as beautiful as
1:42
what we saw before.
1:43
so, the last thing to do will be to just drop in
1:45
a little bit of web design
1:47
and then we'll be actually done.
1:49
Kind of amazing.
