Question

And the result is:

There has been added countryId column. What I must to do fix this?

Answer 1

To do this you have to use decorator @RelationId like this:

export class Province {
  //...
  @Column()
  @RelationId((province: Province) => province.country)
  public countryId: number;
}

Please use next time block code with code definition.
