Typeorm – 如何使用 TS `Relation` 类型来处理一对多关系？

Question

On the Typeorm FAQs page , the docs give instructions to wrap entities in a Relation type to prevent circular dependencies, but the example they give is with a one-to-one relationship. This leaves the solution for a many-to-one or one-to-many rather ambiguous. Which of the following would be the correct implementation?

@Entity()
export class User {
    @OneToMany(() => Profile, (profile) => profile.users)
    profiles: Relation<Profile[]>;
}

or

@Entity()
export class User {
    @OneToMany(() => Profile, (profile) => profile.users)
    profiles: Relation<Profile>[];
}

Or, does it even matter which way you do it?

Answer 1

This should be the right form as you already provided:

@Entity()
export class User {
    @OneToMany(() => Profile, (profile) => profile.users)
    profiles: Relation<Profile[]>;
}
