V5 - How to override the default namings of Lucid ORM

[guntribam]

I'm new to adonis.

I was trying to create Factories using two Models

export default class Usuario extends BaseModel {
  public static table = 'USUARIO'
  
  @column({ isPrimary: true })
  public id: number

  @column()
  public nome: string

  @hasMany(() => Conta)
  public contas: HasMany<typeof Conta>
}

export default class Conta extends BaseModel {
  public static table = 'CONTA'

  @column({ isPrimary: true })
  public id: number

  @column()
  public nome: string

  @column({ columnName: 'idUsuario' })
  public idUsuario: number

  @belongsTo(() => Usuario)
  public usuario: BelongsTo<typeof Usuario>

}

export const ContaFactory = Factory
    .define(Conta, ({ faker }) => ({
        nome: faker.finance.accountName()
    }))
    .build()

export const UsuarioFactory = Factory
    .define(Usuario, ({ faker }) => ({
        nome: faker.name.firstName()
    }))
    .relation('contas', () => ContaFactory)
    .build()

But when a try to run my factory inside a seeder:

export default class DatabaseSeeder extends BaseSeeder {
  public async run() {
    await UsuarioFactory.with("contas", 1, conta => conta)
  }
}

Exception: E_MISSING_MODEL_ATTRIBUTE: "Usuario.contas" expects "usuarioId" to exist on "Conta" model, but is missing

How can i override these naming strategies? how can say to Lucid that I'm using "idUsuario" instead of "usuarioId"?
Also, how can change the naming strategy of "node ace make:migration " for stopping putting "s" on the end of the file?

I would appreciate some tips for overriding other things in Lucid...

Just found one answer in the docs, sorry:

export default class Usuario extends BaseModel {
  public static table = 'USUARIO'
  
  @column({ isPrimary: true })
  public id: number

  @column()
  public nome: string

  @hasMany(() => Conta, {foreignKey: 'idUsuario'})
  public contas: HasMany<typeof Conta>
}
