Error on Referencing a relation column in Unique constraint.

I’m trying to add a Unique constraint with 2 columns where one column is the id column of the same entity and second column is the id column of the @ManyToOne relation column.

This isn’t working and TypeORM throws error: Error: Index contains column that is missing in the entity: albumId

Here’s my class:

@Entity()
@Unique('test_index', ['id', 'albumId'])
export class Photo {

  @PrimaryGeneratedColumn()
  id: number;

  @ManyToOne(type => Album, album => album.photos)
  album: Album;

What I am trying to achieve is to create a Unique index on combination of 2 columns where 1 column (albumId) is supposedly the foreign key column generated by TypeORM.

What’s the correct way to reference the albumId column in Unique index?

I also tried @Unique('test_index', ['id', 'album.albumId']) but that didn’t work either.

Thanks!

Just exclude the Id part.

You should declare your albumId column (it doesn’t interfere on the relation).

You can declare it as private if you are not going to use it:

@Column({ nullable: true })
private albumId: number;
