What is the correct way how to create relation in typeorm?

Question

I have two entities:

@Entity({ name: \'provider\' })
export class ProviderEntity extends GenericEntity {

    @Column()
    name: string;

    @Column()
    descr

I believe to associate things by a relation ID, and not a full relation object, you need to add the relation ID to your interface:

@ManyToOne(() => ProviderEntity, provider => provider.items)
provider: Promise;

@Column()
providerId: string

providerId is the column TypeORM uses to keep track of the relation internally, you simply simply need to expose it publicly.

And then you simply set that property:

const item = new ItemEntity();
item.content = content;
item.providerId = providerId; // set providerId column directly.

await this.repository.save(item);
