Is this just because I'm calling my own api path? because I tried the "use server" method. It brought it successfully, but the data I just added did not come.

"use server" is only applicable to server actions, it is not applicable to components

as for why the fetch failed, it is because your api is not running during build, just read the link

import { prisma } from "~/lib/prisma";

export default async function Page() {
const user = await prisma.user.findUnique({ where: { id: 123456 } });
return <div>{user?.name}</div>;
}

I made all the pages in this style. After I got "npm run build" I started it with "npm start" command. Later, I added a new user from the panel and although I did it like the example there, the added data did not come to the Users List.

that is because your page was rendered statically; if you want to update it you have two choices:

* use dynamic rendering for it https://nextjs.org/docs/app/building-your-application/rendering/static-and-dynamic-rendering

* and/or use on-demand revalidation where you revalidate the page of interest using revalidatePath https://nextjs.org/docs/app/building-your-application/data-fetching/revalidating

Just like "use server", the same example I did is a situation.

again, use server is not applicable to components, it is simply not relevant

alright, add
export const dynamic = 'force-dynamic'
to the page

if you want to see why, read at least the first link here

makes sense, I've seen it in the documentation before 😄

Now it's a bit more like I wanted, but I want to learn one more thing. Like Revalidate. After adding a user on the admin panel Add New User page, if the operation is true, I redirect directly to the User List page. but the new member I added there hasn't arrived yet. until I refresh the page and how can I get around this problem?

i dont understand your question but the two links i provided should give you the relevant information

export const dynamic = 'force-dynamic';
export const revalidate = 1;
