We've written the sections here so that our redirects now come out of the database. It's time to do the same thing for the pages,
0:09
and you'll see it's really straightforward. Instead of doing that little part, we're just going to have our recession try.
0:18
Do the query finally close the session pattern that we've been using for everything. But now he's gonna be based on pages we gotta import.
0:29
And this one we're trying to find it by the earl So we'll say Page on your URL is the base euro Well, actually, that looks pretty good.
0:40
And it's now going to return a page. Okay, I'm happier, That one. That's pretty straight for Let's just copy this, cause organise that over and over.
0:51
All right, get a page. Should be working. Come down here and say we want all the pages again.
0:57
This is even easier. We can just say that all but it would be nice to have them showing the newest ones first,
1:03
cause you most likely want to work with the ones that you've just created or modified So let's go and do it. Order my page, not created date.
1:12
If we do like that it's us ending. But we want the newer ones will do to sending Nice and changed it to a
1:19
list of pages. And here we'll get get paged by I d. We had to do this weird, funky stuff because of our data structure,
1:29
but in a real database, we don't have to be weird at all. We can say I d is. Hey, JD. All right, well, that's pretty straightforward. And again,
1:38
optional page, not optional dictionary. Go to page. Okay, when I said our data and store it, But not like that time, we're gonna create a page,
1:53
right? Like so and then just set the few things we have to set. Like the title is gonna be the title of that strip contents will be the contents
2:05
that strip in the euro. You're all not strip and the lower case. Okay, that all looks pretty good.
2:18
And let's go ahead and return the page that we created here. And we can say when you create it, you're gonna also get it back.
2:25
We probably won't do anything with it, but just in case, you know, when we hit, save much we're not doing yet.
2:31
We had saved it's going to set things like the created date as well as the idea is the one. I guess we also need tohave the creating user.
2:44
And that's to say that these are all strings. We don't set the creating user. We already saw that crashes. Next,
2:55
we gotta add this to the session and then commit the session over to the database All right, that's probably the tricky is one,
3:05
but I think that we're good. Let's go down to our update page and again, we got to get this from a new session.
3:13
We can't call this function, even though it would give it back to us.
3:16
So let's do you copy this really similar that we're gonna create this session and get the page back, worried by page and filter by what we got.
3:35
I d think we're passing in the I D. So it's use that that's the most likely to work, or it's not gonna change ever.
3:44
And we'll do a little test like so I don't need any of this. We're no longer passing in the create user. That's just whoever originally created it.
3:55
There's not, like a last updated by or something so we don't need that. We're sending all the things it came from the database.
4:01
We're off to add it and yeah, that's that's it. We can say this is going to return a page. It doesn't need to be optional,
4:09
cause at this point, it's definitely here. And if it's not gonna be, there's a rash is an exception.
4:16
All right, well, it looks like we've updated our CMS service to now work with sequel alchemy and read and write those pages from the database.
