get a relation key for side of OneToOne

Issue type: [X ] question Database system/driver: [X ] mysql / mariadb TypeORM version: [X ] latest

How now it is possible to find out from which column they are related?

I performed a search I need links

getRepository (this.constructor) .metadata.findRelationWithPropertyPath ('l10n');

Expected Result: id_category

@Entity("categories", {})
export class CategoriesModel extends ORM {

    @OneToOne(type => L10nCategoriesModel, l10n => l10n.categories, {
        eager: true,
        cascadeInsert: true,
        cascadeUpdate: true,
        cascadeRemove: true,
        onDelete: 'CASCADE'
    })
    l10n: L10nCategoriesModel[];

}

@Entity("l10n-categories", {})
export class L10nCategoriesModel extends ORM {

    /* id_category */
    @OneToOne(type => CategoriesModel, category => category.l10n, {
        onDelete: 'CASCADE'
    })
    @JoinColumn({
        name: 'id_category',
    })
    categories: CategoriesModel;
}

You can do it only from the owner side of the relationship this way:

@Entity("l10n-categories", {})
export class L10nCategoriesModel extends ORM {

    @OneToOne(type => CategoriesModel, category => category.l10n)
    @JoinColumn({ name: 'id_category' })
    category: CategoriesModel;

    @Column({ name: 'id_category' })
    categoryId: number;
}
