The last thing to do, let's extend this
0:02
let's have, I'm just going to copy and paste
0:05
it'll be a little quicker
0:06
I'm going to call this AccountController.
0:10
And PyCharm asks, can we add this to Git
0:13
I'm going to just say yes you can.
0:15
So we go over to our AccountController
0:17
I'm going to get rid of most of this.
0:19
The name has to be changed, so let's just
0:21
comment this out for a second.
0:23
But just so we have the pieces in place
0:25
and we'll do the same thing for packages.
0:29
Packages, we're going to write some bits here.
0:32
OK, so for packages, remember
0:34
what were looking for, is we're looking for /project
0:39
that's the way it works.
0:40
Let's just remind ourselves.
0:42
PyPI.org, if we go over to any particular project
0:46
and we click on this, notice the url
0:48
is /project/the name of the package
0:52
with a /.
0:54
Okay, so that's what we're aiming for
0:57
something like that.
0:59
And let's put a little project, package
1:05
name bit in there.
1:07
So this is the route that we're looking for.
1:09
And let's call that package_details.
1:18
And this is going to be packages
1:21
uh, not index, how about details?
1:24
For now, let's just return no data.
1:28
We'll return the package name in just a minute.
1:32
Okay, great, this is looking a little broken
1:35
but it's actually not broken
1:36
that's just PyCharm not quite refreshing itself correctly.
1:39
So we've got our home, it says home
1:42
let's just call this details.
1:45
It's going to be contained in the packages
1:47
so it'll be packages.details, that's
1:48
we don't really need, since we've broken this
1:51
up into the modules by category
1:53
we don't need to put them on the method names.
1:56
So we need to add this.
1:57
If we try to run this now
2:01
and we refresh, well, actually, it doesn't even run.
2:04
Didn't make it that far.
2:05
If we come over here and we look
2:07
you'll see, no route named package_details
2:11
found in view registration.
2:13
Alright, so the next thing to do is going to be go fix that.
2:16
So that brings us back to this method
2:18
we were working on before.
2:20
So we've got our stuff to do with home_controller
2:24
maybe, we'll put it like that, I don't know.
2:26
Over here we'll have packages
2:28
or PackageController.
2:31
And we're just going to do the same thing.
2:32
config.add_route
2:34
and we're going to give it a name.
2:36
What'll we call it, project_details, I think?
2:39
Let's look, no, package_details.
2:42
So we'll say package_details
2:45
and the url is actually going to be /project
2:49
/ whatever the name is.
2:51
Now, something that's a little bit annoying
2:54
with Pyramid routes is
2:56
whether that's there or not makes a big difference.
2:59
And if you want to let them put it there
3:00
or not put it there, it's not a great option.
3:03
So what we can do is, like
3:05
have two routes, one with a /
3:07
and one without a /, it's okay.
3:10
It's not great, but it'll do.
3:12
So if we come over here, for that to work
3:17
we're going to have to have both routes here.
3:20
So let's rerun this, and it should just say
3:23
the details is not found, so we'll fix that next.
3:25
But let's see that we can get a little farther
3:27
what we did, it ran, that's good.
3:29
If we refresh it, we come over here to
3:32
/project/requests.
3:37
Great, details wasn't found.
3:38
So the next thing we have to do is just put the details
3:40
in there, easy enough.
3:44
So let's go down here and
3:46
what's a great example?
3:47
Let's take about is pretty simple.
3:49
Let's paste that as details
3:52
just copied and pasted in PyCharm.
3:54
We'll go over here and we'll have package
3:57
and I'm just going to put the name, package name.
4:09
We'll figure out the details when we get
4:10
to the data access section
4:12
but let's just work on the route to make sure
4:14
this is loading the correct one, okay?
