Is it possible to create Dynamic Pages

Hey guys. I’m just mucking around making a site for myself and wanted to create dynamic pages but I can’t seem to work out how.

This looks like it should work but it creates $NewPage as a string so it fails.
This is a pastebin of the whole script -

This is the section I am having trouble with.

$SeriesCollection = @()
foreach ($Series in ($MyBooks.series_overview_title | Sort-Object -Unique)) {
    $NewPage = New-UDPage -Name "$Series" -Icon "home" -Content {
        New-UDCard }

    New-Variable -Name $Series.Replace(" ", "_") -Value $NewPage -Force
    $SeriesCollection += $Series.Replace(" ", "_")

$a = @()
foreach ($Series in $SeriesCollection) {
    $a += ("$" + "$Series")
#$allVaribles = $a -join ","

# Create Dashboard and Add Pages. 
$MyBooksDashboard = New-UDDashboard -Theme $Theme -Title "GRDB" -Pages @($a) -EndpointInitialization $EI

#Run Dashboard
Start-UDDashboard -Dashboard $MyBooksDashboard -Port 7777 -AutoReload -Endpoint @($EndpointMyBooks) 

It looks like it should work but the $NewPage is a string so it won’t read it. Has anyone tried something like this that could help me out?

This is the contents of $MyBooks[1] for an example of its contents

                                     the Forgers have not forgotten. They have spent decades preparing, gaining power, and now their plan has nearly reached fruition. <br /><br />On the outskirts of the city, living within the stronghold of ancient power, Haern longs

                                     victory. His inexperience might kill him, but his instincts might be the reason they succeed. <br /><br />For Daniel, a member of the ruling family, life in the palace is easy and his path is clear. Eventually, he will rise up to sit

I found out there is something built in for dynamic pages but I can’t work out how to use it.
This is the example from the site:
$Dynamic = New-UDPage -Url “/dynamic/:name” -Endpoint {
$ScriptColors = @{
BackgroundColor = “#5A5A5A
FontColor = “#FFFFFF
New-UDCard @ScriptColors -Title “Welcome to a dynamic page, $name!” -Text “This is a dynamic page. The content of the page is determined by the URL.”

It sets param($name) but i’m not sure how I can pass that an array of strings.
I would expect something like this

New-UDPage -Name $StrArray -Endpoint{

This way i would be creating a new page for each item in the array…

Anyone help with what i’m missing?

You found the right example.
But you have to change your concept I think.
On the HOME you can list all your books with a link.
If you click the link, you can forward to One UD-dynamic page + a book variable.
Then you do the rest of your code with the details for the provided book-variable.

So, if i’m following. It doesn’t actually create a bunch of pages that would show in the menu for example, but will create the page when the link is followed.
That does make more sense, i was thinking it might end up taking ages to run, but if its doing it on the fly that would solve that issue.
I was sure there was something wrong with my logic, but unfortunately I couldn’t think of another way to do it.

Thanks for the tip. I’ll rework it and see what happens.

Hi Gary, glad that this could a help you a bit.
If you want it in the menu, you can also add the links in the menu with New-UDSideNavItem.
But if you have a lot of books to display a searchable grid can have some advantages.
I am curious what you will achieve.

Best wishes Marco

I don’t need it in a menu, was just using that as a example of what i thought it was doing…

I was looking for an idea an landed on my ebooks because I have all these series that I haven’t finished. So, I thought a good little dashboard for me would be to have a page with all the series and show on the card ‘Books owned’ \ ‘Total books’ in series (pulled from goodreads which already has this info, so its a useless dashboard). Then when I click on the card I was thinking of going to a new page that contains a card for each book in the series with unowned in a lighter colour to show they are not owned.

It’s really just about learning more about the app, I want to build up a bunch of these dashboard\portals for work so that I can get them to buy it. Right now my company is deciding on the systems that are hosting the data so I can’t build anything until I know if they are going to stick with the current applications or not.
I have built a simple dashboard that I use, it has some things like LAPs lookup, tickets open, zoom rooms etc, so I have no problem with using APIs etc, just getting them into a portal to make it useful.

My issue with PUD seems to just be how to pass things into a foreach loop. I keep wanting to put a variable in the parameters of the function but that always fails or crashes the dashboard.

for example.
Foreach ($a in $b){
New-udcard -title $a -content {

Hi Gary, thanks for sharing your background. I am in a similar situation. Looking around with a lot of ideas, but at first want to know everything about it, before I go in a project for business. To create a private project is a very good idea. It helps to learn an understand, but keeps the pressure away that it brings when you say “I will build a ud for a important business case”

For your problem. When I see your code snippets. I think you do not need help with the basics.
Maybe your foreach does not work because the $b array was created outside of an Endpoint and you try to enumerate it inside of an Endpoint?

The endpoints are seperate runspaces, so you have to pass variables with -Argumentlist
Or by utilizing the scopes $cache: or $session: that Adam created.

Best wishes, Marco

So it was just something really simple.
I was storing my info like this $Cache:Var but calling it like this $Var
Just had to call it with the $Cached: part and it works as expected.

Its still not behaving like I would expect.

Take this for example

$Pages = New-UDPage -Name "Home" -Icon "home" -Content { 
    New-UDLayout -Columns 6 -Content { 
        foreach ($Cache:Book in $Cache:MyBooks) {
            New-UDCard -Title ($Cache:Book.title) -Content {
                New-UDImage -Url ($Cache:Book.large_image_url)
                New-UDButton -Text "Series Overview" -OnClick {
                    Show-UDModal -Content {
                        New-UDParagraph -Text ($Cache:Book.description)
                New-UDParagraph -Text ($Cache:Book.description)
            }  -Size 'small' -BackgroundColor "#404552"
} -AutoRefresh -RefreshInterval 120

This line here (in New-UDCard) works as expected and displays the right description.
New-UDParagraph -Text ($Cache:Book.description)

This one on the other hand only displays the last description that was gathered at the end of the foreach loop.

Show-UDModal -Content {
            New-UDParagraph -Text ($Cache:Book.description)

So it looks like the code in the show-udmodel is only generated when the button is clicked. But I want the contents to be in there already.
