Why are you using ViewBag and not typed models?

0x05962OP•15mo ago

Simplier but holdon could it be my javascript

like the redirection? if not ima try the strong typed models

Angius•15mo ago

Well, your view won't update just because you set some variable in the backend, if that's what you're trying to do If it's rendered server-side, like a view, it's rendered, sent to the browser and that's it To update the data you would have to reload the page And make sure whatever new data you want is added during that request Or you can use JS to avoid the reload

I am using js I don't understand much but a model would fix this?

Angius•15mo ago

But also render things server-side?

0x05962OP•15mo ago

I thought the server would send it to the view

Angius•15mo ago

It would make more proper code, but no, it's unlikely to solve the issue

0x05962OP•15mo ago

Angius•15mo ago

Your problem stems from the fundamental misunderstanding how websites work, what's done on the server, what's done on the client, and so on

So I can use js to get the viewbag??

Angius•15mo ago

No JS has no concept of a viewbag

0x05962OP•15mo ago

ik but like a get request to the controller

Angius•15mo ago

Sure, that you can do

0x05962OP•15mo ago

How would you do it I think my code is poorly structured as I have not used one query 💀

Angius•15mo ago

You would have an API controller

[ApiController]
[Route("[controller]")]
public class SomethingController : ControllerBase
{
    [HttpGet]
    public ActionResult<int> GetRandomNumber()
    {
        var rand = Random.Shared.Next(0, 100);
        return Ok(rand);
    }
}

[ApiController]
[Route("[controller]")]
public class SomethingController : ControllerBase
{
    [HttpGet]
    public ActionResult<int> GetRandomNumber()
    {
        var rand = Random.Shared.Next(0, 100);
        return Ok(rand);
    }
}

something like this That you would then call with JS

const res = await fetch('/something');
const num = await res.text();
alert('Your number is ${num}');

const res = await fetch('/something');
const num = await res.text();
alert('Your number is ${num}');

Is there something I can use to store data across controllers and not use database

Angius•15mo ago

A file, if you really want But a database would be ideal

0x05962OP•15mo ago

like literally build a mongodb for this stuff? or would cookies do

Angius•15mo ago

You don't need to build anything And cookies are client-side You can use SQLite with EF Core Or LiteDB

0x05962OP•15mo ago

also what does return RedirectToAction("Data", "Stock"); do in the controller

Angius•15mo ago

It redirects to another action

0x05962OP•15mo ago

so it'd call the IActionResult Data()?

Angius•15mo ago

https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.controllerbase.redirecttoaction?view=aspnetcore-7.0 Why? Why do you even need to redirect in the first place?

Chatgpt said to do it to pass the viewbag

Angius•15mo ago

Well, ChatGPT is very often confidently incorrect So

0x05962OP•15mo ago

so if somehow I did a post request from the browser to the server right and the controller returns a view the browser view will change?

Angius•15mo ago

If you do it with a form or a link, yes If you do it with fetch, XHR or ajax, no

0x05962OP•15mo ago

lol holdon so the viewbag goes where then

Angius•15mo ago

Viewbag is, tentatively, used to pass data between the controller and the view And, sometimes, between views and layouts

0x05962OP•15mo ago

and models can be passed to js?

Angius•15mo ago

Yes, they can be returned from a controller instead of a view

0x05962OP•15mo ago

cause ig it's not dynamic ohh Also when is it appropiate to have like this on your website

0x05962OP•15mo ago

Angius•15mo ago

Uh, when you want to? You can make a complete website that never changes the address bar All navigation is done with JS A so-called SPA, or Single Page Application But you sometimes want people to, dunno, send eachother links to specific videos on youtube Or to a privacy policy Or something So... then
