model-d | Control app for Behringer Model D | Audio Utils library

I'm trying to understand AR models but it's getting pretty difficult for me. Just wanted to ask you some hints on how to simulate an AR(2) model-driven by input as we wish (constant, coefficient, sd, for n values in R, without using any built function.

I'm trying to have a field in one Pydantic model accept any of a set of BaseModel-derived classes or subclasses that I define separately. Reading the docs here, I naively did the below, which failed; I then realised that I'd misread the docs and that in this scenario "a field may only accept classes (not instances)", and also that Foo and Bar in that example don't derive from BaseModel themselves (is that important?).

I'm guessing that I'm just misconceiving this from the start, so my question: is there a correct way to do what I'm trying to do without using a Union on the subclasses, or some other way entirely that's better?

Bonus question: what's a common usecase for only being able to accept classes and not instances?

MRE:

I don't figure out how to get the number of days betwen twoo dates: this is the models I have :

I am getting a pdf from:

return this.http.get(path, { observe: 'response', responseType: 'arraybuffer' });

and processing it as a blob:

let blob: Blob = new Blob([response.body], { type: 'application/pdf' });

I am now looking to store that file locally and reference it through a local url. The reason I need to use a url is because the viewer.loadModel() requires it as a parameter. I have tried using let url = window.URL.createObjectURL(this.blobToFile(blob, 'viewer.pdf')); to get a url.

When i do that I get: https://localhost:3000/35ef3b8e-e59f-4fe9-a8cc-1e2e542ffb2a The viewer doesn't know the file type without the '.pdf' behind it though. If I put .pdf behind that url: https://localhost:3000/35ef3b8e-e59f-4fe9-a8cc-1e2e542ffb2a.pdf, it seems to load some data but I get the following error:

I have created many Canvas apps and integrate SharePoint list as data source in PowerApps. Now, i will need to create Modern Driven apps in PowerApps and get data from SharePoint list.

Do model-driven apps only run on Common Data Service (CDS) entities? Or can they also run on data from other sources (like SharePoint lists or SQL Server tables)?

Can anyone help me for the same? Thanks in advance.

I'm using MLKit with iOS in a react native project.

Basically using this code: https://firebase.google.com/docs/ml/ios/label-images-with-automl

It used to work fine but now i get this error:

I'm trying to add a button and have it open a "create new" form for my entity using a specific form. I've added the button using the ribbon workbench and I get successfully trigger JavaScript however I'm having trouble getting the right form to display - I always get the default one.

My code is quite simple:

I'm trying to scrape the descriptions of ebay listings, and was approaching it with this:

I'm in search of a way to set up and call functions with arbitrary arguments and return types. One use case would be high level scripting. Something like this:
