Nestjs prisma model - v0 by Vercel

I'm using Nestjs with prisma Implement a new model called AccountConfiguration This is related 1 to 1 with a Model called Account (with int key called id) The field for AccountConfiguration model is is_monthly_billing_supported for now, type boolean and the corresponding foreign key

I'll help you implement a new AccountConfiguration model with a one-to-one relationship to your existing Account model in Prisma.

In this implementation:

I've created a new AccountConfiguration model with the is_monthly_billing_supported boolean field.
I've set up a one-to-one relationship between Account and AccountConfiguration 1.
The accountId field in AccountConfiguration serves as the foreign key that references the id field in the Account model.
The @unique attribute on the accountId field ensures that each Account can have at most one AccountConfiguration, making it a true one-to-one relationship 1.
I've added a relation field accountConfiguration to the Account model that references the AccountConfiguration model.

After adding this to your schema, you'll need to run a migration:

npx prisma migrate dev --name add_account_configuration

This will create the new table in your database with the proper relationship to the Account table.

Generate the answer again, I need to ensure an AccountConfiguration instance is created for all existing accounts and new accounts. Also give me the different options to create the AccountConfiguration instance for all existing accounts

I'll help you implement the AccountConfiguration model and ensure it's created for all accounts.

Options to Create AccountConfiguration for Existing Accounts

Here are different approaches to create AccountConfiguration instances for all existing accounts:

Option 1: Using Prisma Client in a Migration Script (as shown above)

The migration script I provided uses Prisma Client to:

Find all accounts without an AccountConfiguration
Create a new AccountConfiguration for each account

To run this script:

npx ts-node prisma/migrations/create-account-configurations.ts

Option 2: Using SQL Directly in a Migration

You can create a SQL migration file:

-- Create AccountConfiguration for all existing accounts
INSERT INTO "AccountConfiguration" ("is_monthly_billing_supported", "accountId")
SELECT false, "id" FROM "Account" 
WHERE "id" NOT IN (SELECT "accountId" FROM "AccountConfiguration");

Run this with:

npx prisma migrate dev --name add_account_configurations

Option 3: Using NestJS Command

Create a NestJS command:

import { Command } from 'nest-commander';
import { Injectable } from '@nestjs/common';
import { PrismaService } from '../prisma/prisma.service';

@Injectable()
@Command({ name: 'create-account-configurations' })
export class CreateAccountConfigurationsCommand {
  constructor(private prisma: PrismaService) {}

  async run(): Promise<void> {
    const accounts = await this.prisma.account.findMany({
      where: {
        accountConfiguration: null,
      },
    });

    console.log(`Found ${accounts.length} accounts without AccountConfiguration`);

    for (const account of accounts) {
      await this.prisma.accountConfiguration.create({
        data: {
          accountId: account.id,
          is_monthly_billing_supported: false,
        },
      });
      console.log(`Created AccountConfiguration for account ${account.id}`);
    }

    console.log('Migration completed successfully');
  }
}

Run with:

nest create-account-configurations

Ensuring New Accounts Always Have an AccountConfiguration

For new accounts, I've provided an AccountService that creates both an Account and its AccountConfiguration in a transaction. This ensures that every new account will have an associated AccountConfiguration.

To use this in your NestJS controllers:

@Post()
async createAccount(@Body() createAccountDto: CreateAccountDto) {
  return this.accountService.createAccount(createAccountDto);
}

This approach ensures data integrity by using transactions, so if either the Account or AccountConfiguration creation fails, the entire operation is rolled back.

Regenerate the answer, but now keep this information in mind: Add the following fields:

is_monthly_billing: Boolean, default value False.
is_monthly_billing_supported: Boolean, default value False.
source: Enum (LeasingOrderSource) with values registrant / auto, default value registrant.
Create an index for id

Run this with:

npx prisma migrate dev --name add_account_configurations

Option 3: Using NestJS Command

Create a NestJS command:

import { Command } from 'nest-commander';
import { Injectable } from '@nestjs/common';
import { PrismaService } from '../prisma/prisma.service';

@Injectable()
@Command({ name: 'create-account-configurations' })
export class CreateAccountConfigurationsCommand {
  constructor(private prisma: PrismaService) {}

  async run(): Promise<void> {
    const accounts = await this.prisma.account.findMany({
      where: {
        accountConfiguration: null,
      },
    });

    console.log(`Found ${accounts.length} accounts without AccountConfiguration`);

    for (const account of accounts) {
      await this.prisma.accountConfiguration.create({
        data: {
          accountId: account.id,
          is_monthly_billing_supported: false,
        },
      });
      console.log(`Created AccountConfiguration for account ${account.id}`);
    }

    console.log('Migration completed successfully');
  }
}

Run with:

nest create-account-configurations
