As you saw
0:01
we can use routing to actually capture arbitrary URLs.
0:05
Use our Jinja templates and our common layout
0:08
to actually create a very simple CMS
0:11
with almost no code.
0:13
Here's most of the implementation honestly right here.
0:15
So we want to create a route
0:16
and instead of just having slash some variable
0:19
we're going to say this variable is of type path
0:22
and that means it's going to capture
0:23
not just stuff between a given set of slashes
0:26
or on the end of a URL
0:28
but the entire thing after a forward slash.
0:31
So that lets us grab the URL
0:33
in case none of the other ones already match
0:36
and then what we're going to do
0:37
is just go to the database and say
0:39
"Hey if we entered something for this URL and if so
0:42
let's get a page title and a piece of content
0:45
and just show it wrapped up in our common layout."
0:48
How cool is that?
0:49
And it took us definitely less than 10 minutes to build it
0:51
from scratch. Now we didn't build the editing backend
0:55
that lets you type in the title, the URL
0:57
and the page content probably is marked down
0:59
and rendered as HTML.
1:01
Y'know that is a simple exercise
1:03
it's not a ton of work for you to do that.
1:04
This is enough to get you started.
1:06
This is the hard part technically speaking
1:08
this is the part you have to understand that's tricky
1:10
and then from there on out it's pretty straightforward.
1:13
This shows you some of the power of routing in Flask.
