EntityFactory using .map give me an error

I ran the example (User and Pet) that you have here and I am getting this error:

(property) User.pets: Pet[] This expression is not callable. Type 'Pet[]' has no call signatures.

I used this as seeder:

await factory(User)() .map(async (user: User) => { const pets: Pet[] = await factory(Pet)().createMany(2) const petIds = pets.map((pet: Pet) => pet.Id) await user.pets().attach(petIds) }) .createMany(5)

Any idea?

I look up the source code, nothing is related to the attach method. Finally, I use the following way to achieve that

seeds

/src/database/seeds/create-users.seeds.ts

import { Factory, Seeder } from 'typeorm-seeding';
import { User } from '../../users/user.entity';
import { Task } from '../../tasks/task.entity';

export default class CreateUsers implements Seeder {
  public async run(factory: Factory): Promise<any> {
    const users = await factory(User)().createMany(10);

    for (const user of users) {
      const { id } = user;

      await factory(Task)({ id }).create();
    }
  }
}

factory

/src/database/factories/task.factory.ts

import Faker from 'faker';
import { define } from 'typeorm-seeding';
import { Task } from '../../tasks/task.entity';
import { TaskStatus } from '../../tasks/task-status.enum';

interface Context {
  id: number;
}

define(Task, (faker: typeof Faker, context: Context) => {
  const { id } = context; // <--- here!

  const title = faker.lorem.words();
  const description = faker.lorem.paragraph();
  const status = faker.random.objectElement<TaskStatus>(TaskStatus);

  const task = new Task();
  task.title = title;
  task.description = description;
  task.status = status;
  task.userId = id; // <--- here!
  return task;
});

thanks, works well with me . my once editing to solve the error was shown to me is making (faker: typeof Faker, context: ViewInterface | any)
