How to seed a factory which has a oneToMany relationship using other factory

[yesid-lopez]

Hey, I'm trying to seed my db for a specific entity, and I would like to take advantage of other factory to populate my entities. As you can see, I'm expecting to create 4 common areas with an array of available days, however only one entity is created in that way, the other ones are empty as you can see in the last json:

    const commonAreaFactory = await factoryManager.get(CommonArea);
    const availableDayFactory = await factoryManager.get(AvailableDay);

    const availableDays = await availableDayFactory.saveMany(3);
    await commonAreaFactory.saveMany(4, { availableDays: availableDays });

      },

      }
    ]

I tried this one an looks like it works

export default class CommonAreaSeeder implements Seeder {
  public async run(
    dataSource: DataSource,
    factoryManager: SeederFactoryManager,
  ): Promise<any> {
    const commonAreaFactory = await factoryManager.get(CommonArea);
    const availableDayFactory = await factoryManager.get(AvailableDay);

    const commonAreas = await commonAreaFactory.saveMany(3);
    commonAreas.forEach(
      async (commonArea) => await availableDayFactory.saveMany(3, { commonArea }),
    );
  }
}

Output
