Hi i am new to Nest and I am trying to follow the guide from https://docs.nestjs.com/recipes/prisma to test out this function, but after prisma generate, my app couldn't find the schema in prisma/client: "Module '"@prisma/client"' has no exported member 'User'.",
"Module '\"@prisma/client\"' has no exported member 'Post'.", ; Can someone help me with this problem I try to search stack overflow but no answer found and some said it could relate to the prisma version.

Yea this is an issue in the official guide.
The command npx prisma init actually outputs the below as the schema.prisma file:
// learn more about it in the docs: https://pris.ly/d/prisma-schema
// Looking for ways to speed up your queries, or scale easily with your serverless or edge functions?
// Try Prisma Accelerate: https://pris.ly/cli/accelerate-init
generator client {
provider = "prisma-client-js"
output = "../generated/prisma"
}
datasource db {
provider = "postgresql"
url = env("DATABASE_URL")
}```
The key difference here is the "output". As soon as we set this then we are no longer importing the User or Post from @prisma/client, but instead from "generated/prisma".So your controller et al should get the imports from that new generated file directory like so:
import {Controller, Get, Param, Post, Body, Put, Delete,
} from '@nestjs/common';
import { PostService } from './post/post.service';
import { UserService } from './user/user.service';
import { User as UserModel, Post as PostModel} from 'generated/prisma'
@Controller()
export class AppController {
constructor(
private readonly userService: UserService,
private readonly postService: PostService,
) {}
@Get('post/:id')
async getPostById(@Param('id') id: string): Promise<PostModel | null> {
return this.postService.post({ id: Number(id) });
}
@Get('feed')
async getPublishedPosts(): Promise<PostModel[]> {
return this.postService.posts({
where: { published: true },
});
}
///etc...
}
How about the PrismaService, is the problem the same? Property "user" does not exist in type "PrismaService"

No clue how you got that error to be totally honest.
Can you share your prisma.service.ts file? It should look like this:
import { Injectable, OnModuleInit } from '@nestjs/common';
import { PrismaClient } from 'generated/prisma';
@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit {
async onModuleInit() {
await this.$connect();
}
}
Yea i have fixed to that and now i have a new error: could it be relate to that there is no data in the database yet?

Nah, that's just a very common NestJS specific error due to your modules missing service/controller imports.
In your app.module.ts file, you should ensure you have the services that module holds as "Providers"
import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { PrismaService } from './prisma/prisma.service';
import { PostService } from './post/post.service';
import { UserService } from './user/user.service';
@Module({
controllers: [AppController],
providers: [AppService, PrismaService, UserService, PostService,],
})
export class AppModule {}
Take a look through https://docs.nestjs.com/modules for more information. You'll encounter this very often as you use NestJS...
-> Controllers are the endpoints for that module
-> Providers are the services (and other things but you'll get to those as you work with NestJS more I'm sure)
-> Imports are where you designate other services from other modules (or entire modules) that you want the existing services/controllers in the current module to work with
-> Exports are where you designate what parts of the current module you want to export into other modules/services.
Getting to grips with this structure is essential to using NestJS.
My personal reccomendation for a brief intro to all this is Dave Gray's tutorial series (https://www.youtube.com/watch?v=juNVinepwKA&list=PL0Zuz27SZ-6MexSAh5x1R3rU6Mg2zYBVr). Although its a little over a year old at this point the main part of it is still useful.

Can you share your prisma....
My prisma service is exactly like yours
Thank you, i will look into that

Don't hijack threads. Start a new thread with your problem and if this thread is relevant, you can link to it in your new thread.

any update to this ? I also follow to documentation, but endup in a esmodule error
<>Object.defineProperty(exports, "__esModule", { value: true });
^
ReferenceError: exports is not defined in ES module scope<>
is this most like a framework bug ? got stcuk at the moment T_T
teal lintel
i can tell you is relate to framework version, i also spent for additional 2 months just to watch learn and try to make a project using nest. watch the series above and also do some research, worst case you can ask AI.
For the above i can hint that it is simply syntaxes
