The final thing I want to look at
0:01
is changing our project structure
0:03
a little bit for these shared layouts.
0:05
And you saw just a hint of that
0:07
in our example previously.
0:10
As our application grows
0:12
we're going to want to add more and more structure
0:15
for what we're doing.
0:16
Here's a richer PyPI_webapp.
0:20
This is really where we're going
0:22
this is what we're going to come close
0:23
to ending the course with.
0:25
Notice we have a controllers directory.
0:28
This is where I move the views and I broke them
0:30
into different files.
0:31
So the stuff related to accounting, or creating accounts
0:34
is under account controller.
0:36
This general homepage and stuff is under home
0:39
and then package related things
0:41
like package details and so on
0:43
it's in the the packages controller.
0:45
Because each one of those controller modules
0:48
contains multiple views, it makes a lot of sense
0:51
to create a sub folder in the templates page
0:55
that maps to that controller.
0:57
So, for example, we're going to come over and say
1:00
have an account folder in templates
1:02
and put all the related views.
1:03
So when we say index, we don't have to say index_account
1:06
and have them all mushed together.
1:08
We also have one for home
1:09
and potentially one for packages and so on.
1:12
Then we have the shared layout that we talked about.
1:15
So shared underscore indicator as well.
1:17
So those two things they definitely
1:19
don't try to request that directly.
1:23
So most of the views are going to use the _layout.
1:26
Not all of them.
1:27
For example maybe we want to add a site map
1:29
and the site map will be generated by one of these
1:32
page templates but obviously it's just going to be
1:34
an XML document.
1:35
It doesn't make sense for it to use it
1:37
but like 95% of the views will use this shared layout
1:41
or some derivative thereof.
