Database seeding problem.

[Sukanto01899]

I did not understand data seeding.. How run the route file?

Well, after you follow the steps until you reach "Seed Your Database" section, you go to http://localhost:3000/seed to seed the database. You should get a response on the browser screen that says {"message":"Database seeded successfully"}.

My issue is the actual seeding. This part. It seems to not populate my vercel database with the data that it was being seeded with.

My code:

//app\seed\route.ts
import bcrypt from 'bcrypt';
import { db } from '@vercel/postgres';
import { invoices, customers, revenue, users } from '../lib/placeholder-data';

const client = await db.connect();

async function seedUsers() {
  await client.sql`CREATE EXTENSION IF NOT EXISTS "uuid-ossp"`;
  await client.sql`
    CREATE TABLE IF NOT EXISTS users (
      id UUID DEFAULT uuid_generate_v4() PRIMARY KEY,
      name VARCHAR(255) NOT NULL,
      email TEXT NOT NULL UNIQUE,
      password TEXT NOT NULL
    );
  `;

  const insertedUsers = await Promise.all(
    users.map(async (user) => {
      const hashedPassword = await bcrypt.hash(user.password, 10);
      return client.sql`
        INSERT INTO users (id, name, email, password)
        VALUES (${user.id}, ${user.name}, ${user.email}, ${hashedPassword})
        ON CONFLICT (id) DO NOTHING;
      `;
    }),
  );

  return insertedUsers;
}

async function seedInvoices() {
  await client.sql`CREATE EXTENSION IF NOT EXISTS "uuid-ossp"`;

  await client.sql`
    CREATE TABLE IF NOT EXISTS invoices (
      id UUID DEFAULT uuid_generate_v4() PRIMARY KEY,
      customer_id UUID NOT NULL,
      amount INT NOT NULL,
      status VARCHAR(255) NOT NULL,
      date DATE NOT NULL
    );
  `;

  const insertedInvoices = await Promise.all(
    invoices.map(
      (invoice) => client.sql`
        INSERT INTO invoices (customer_id, amount, status, date)
        VALUES (${invoice.customer_id}, ${invoice.amount}, ${invoice.status}, ${invoice.date})
        ON CONFLICT (id) DO NOTHING;
      `,
    ),
  );

  return insertedInvoices;
}

async function seedCustomers() {
  await client.sql`CREATE EXTENSION IF NOT EXISTS "uuid-ossp"`;

  await client.sql`
    CREATE TABLE IF NOT EXISTS customers (
      id UUID DEFAULT uuid_generate_v4() PRIMARY KEY,
      name VARCHAR(255) NOT NULL,
      email VARCHAR(255) NOT NULL,
      image_url VARCHAR(255) NOT NULL
    );
  `;

  const insertedCustomers = await Promise.all(
    customers.map(
      (customer) => client.sql`
        INSERT INTO customers (id, name, email, image_url)
        VALUES (${customer.id}, ${customer.name}, ${customer.email}, ${customer.image_url})
        ON CONFLICT (id) DO NOTHING;
      `,
    ),
  );

  return insertedCustomers;
}

async function seedRevenue() {
  await client.sql`
    CREATE TABLE IF NOT EXISTS revenue (
      month VARCHAR(4) NOT NULL UNIQUE,
      revenue INT NOT NULL
    );
  `;

  const insertedRevenue = await Promise.all(
    revenue.map(
      (rev) => client.sql`
        INSERT INTO revenue (month, revenue)
        VALUES (${rev.month}, ${rev.revenue})
        ON CONFLICT (month) DO NOTHING;
      `,
    ),
  );

  return insertedRevenue;
}

export async function GET() {
  try {
    await client.sql`BEGIN`;
    await seedUsers();
    await seedCustomers();
    await seedInvoices();
    await seedRevenue();
    await client.sql`COMMIT`;

    return Response.json({ message: 'Database seeded successfully' });
  } catch (error) {
    await client.sql`ROLLBACK`;
    return Response.json({ error }, { status: 500 });
  }
}

There seems to be an issue with the given code because i copied your above code and it worked seamlessly

I think you should click the toggle button on the input field to show the dropdown tables.
But if you have any errors I just wanna share the issue that helped me a lot #803

@DSQL-MONGKEY
Thanks, that was my 'issue'. Seems rather unintuitive to have to focus the input for the tables to show up.

[NaufalAlk]

thanks a lot, it fixed by using your code, sir

[HamCraft]

@ruizTechServices Thanks for the code , It Worked!

[NaderFares16]

@ruizTechServices Thanks for the help! It worked here. I had forgotten to remove this:

return Response.json({ message: 'Uncomment this file and remove this line. You can delete this file when you are finished.', });
