Let's go mess with the old documents,
0:02
recall what we had before we had a little filter thing,
0:04
and I'll go ahead and put the text of it up here.
0:09
This isn't going to do anything yet, but we'll have our little
0:11
filter there, and let's put a spacer.
0:13
And then what we need is,
0:14
we want a list of all of the documents.
0:17
How do you do that?
0:18
So far we've set like the text value and so on,
0:20
so what we need for the next thing is actually
0:23
called a linear panel or a repeating panel,
0:26
we'll go for repeating panel.
0:29
Now, there's an item template
0:31
that we've got created right here,
0:32
and I don't like that name, so let me rename this
0:34
to doc_list_item_template.
0:40
If you go down here, we'll see that we have
0:42
the doc_list_item_template, right there, sorry.
0:44
And let's set the name to docs, like that.
0:50
Now, if we actually want to edit that item template,
0:52
we can double click here or just go there,
0:54
we'll double click there and it says
0:56
what items would you like to display?
0:57
Right on the table, how about documents.
1:01
And that means there'll be a little item property
1:03
for each one that comes through here.
1:05
Alright, so within this, how do you want to show it?
1:09
Well, let's go do some more stuff,
1:10
let's set into this thing, we're going to put the title,
1:18
make that bold and go left.
1:22
Put another one right there,
1:31
that's when it's created, and then let's put a link in here,
1:33
so you can click the link to say navigate over and edit it,
1:36
and this is going to be details.
1:47
Alright, make that smaller at that side,
1:49
that created we can make it a little smaller,
1:51
leave some room for the title,
1:53
which is going to be the main thing.
1:55
This is pretty interesting,
1:56
but how do I get the data wired into this?
1:59
Now, we get a little data binding here,
2:01
check that bad boy out right there.
2:03
Self.item of what?
2:04
Well, that is the scheme of our database.
2:08
How cool is that?
2:10
Okay, this should be name,
2:13
and that's looking good. Oops, I don't want this one.
2:15
Self.name and the created,
2:17
we're going to set that up a little bit different,
2:18
but let's just see what we can do to make this work.
2:23
Come into code here,
2:26
go to our utilities, remember it's already loaded the data
2:29
so we shouldn't have to download anything, this is all
2:32
a single paid app, it's amazing.
2:35
So all we have to do is say
2:36
self.repeating_panel.items = utility.docs.
2:42
Let's see if this works.
2:45
Alright, moment of truth, wow,
2:49
it doesn't look like much,
2:50
but that is out of our database right there.
2:52
Super, super cool.
2:54
Let's work on our created date right here.
2:58
Now, if you look over here at the bindings,
2:59
I could try to add a binding,
3:01
and I could have created,
3:03
but I really wanted something like,
3:04
kind of complicated for how I do this,
3:06
like stuff that's happening here.
3:09
So, instead of doing it this way, let's remove that,
3:12
and let's actually go and write
3:13
some code for our doc template.
3:16
Right, so we come over here, and this little item
3:18
thing has been set, actually, I believe it's not set yet.
3:21
We got to be a little careful when the thing is shown,
3:24
or the doc list is shown, then the item has been set,
3:27
so we come down here and say self dot label,
3:31
created dot text, and then we want to use this nice little
3:36
expression here, where we say item.created,
3:39
this is the document, that's it's created field,
3:41
actually, sorry, we got to do it like this.
3:44
Created, and then store format for the friendly
3:48
month, then the day, then the year, let's try that.
3:52
Try all the docs, there you go, March fourth,
3:56
that's today, that's when I created these things.
3:58
Super, super cool, I mean we could make those fonts
4:00
a little bit bigger.
4:01
Last thing is what happens when we click this?
4:03
Right now, nothing.
4:06
So, inside our template,
4:08
when we double click on these details,
4:11
something is going to happen.
4:13
What we want to do is, again tell the home form to navigate
4:17
somewhere, so what we're going to do is we're going to
4:19
write one more function here, kind of like the go_home.
4:35
And we'll tell the home_form to do this thing
4:38
we're calling go_details,
4:39
and what is that?
4:40
Well it's going to show this details form.
4:42
We haven't put that in place yet,
4:43
because it's not a top level navigation item you can do,
4:47
but we'll write it now.
4:53
It's almost the same,
4:58
going to add the doc_details_form.
5:02
Let's pass the doc along,
5:07
and to kind of keep with the pattern
5:08
when you do this binding
5:09
or something is associated with it,
5:11
it's typically item, so I'm going to say item equals this.
5:16
Alright, in our doc_details_form, let's just
5:19
do something like this,
5:20
print self.item name, just to make sure
5:24
that we got the name here, so,
5:29
like that, let's see if the details now work.
5:39
It doesn't, what are we missing?
5:40
Let me check.
5:45
Why didn't it work?
5:46
Well, it doesn't take a genius to figure that
5:49
out does it, look at this, forgot to call it, alright, so let's do our import again.
5:57
Go to details and pass the document that they clicked.
6:02
Remember, the one I clicked was self.item,
6:04
that's the thing that's bound to this particular row
6:07
of our repeating table, so self.item,
6:10
pass that along.
6:14
Click it, what happens?
6:15
Run demo ReadMe,
6:18
oh we didn't pass enough, what's happening here?
6:23
I forgot to put the self parameter.
6:25
Okay, one more time.
6:29
Ready, let's go see the demo ReadMe.
6:32
Boom, we loaded the document demo ReadMe,
6:34
want to try the other, live doc, loaded live doc.
6:37
Yes, it's working.
6:38
So we pretty much have our app all in place,
6:41
the last thing we need to do is sort of replicate this
6:44
view over here on the home,
6:45
as well as filter the documents.
6:47
So what I'm going to do is,
6:48
I'm going to go add a bunch of documents
6:50
so we have things to work with, and then,
6:52
we'll finish out these last two small pieces.
