在使用嵌入式对象时无法填充 @OneToMany

Describe the bug

Hey there! First of all, thanks a lot for this very stable and intuitive TS ORM! ❤️ Since a couple of versions, an @Embeddable can have a @ManyToOne relationship through its parent. This works fine. However, the inverse side that would use a @OneToMany collection cannot populate the user. Stack trace No stack trace since no error. To Reproduce Here is an example setup: ts @Embeddable() export class Address { constructor(street: string, city: string, country: Country) { this.street = street this.city = city this.country = country } @Property() street!: string @Property() city!: string @ManyToOne() country!: Country } @Entity() export class Country { @PrimaryKey({ autoincrement: true }) id!: number @Property() name!: string @OneToMany(() => User, (user) => (user as any).address_country) users = new Collection<User>(this) } @Entity() export class User { @PrimaryKey({ autoincrement: true }) id!: number @Property() name!: string @Embedded(() => Address) address!: Address } You can populate the `country` property from the side of the `User`, but you cannot populate the `users` collection from the `Country`'s side. **Expected behavior** One should be able to populate the `users` collection also from the `Country`'s side. **Additional context** Here is a test suite that explains everything in detail: ts import { MikroORM } from '@mikro-orm/core' import { SqliteDriver } from '@mikro-orm/sqlite' import { Address } from './address' import { Country } from './country' import { User } from './user' describe('Issue', () => { let orm: MikroORM beforeAll(async () => { orm = await MikroORM.init({ entities: [User, Country, Address], dbName: ':memory:', driver: SqliteDriver, allowGlobalContext: true, }) await orm.schema.createSchema() }) afterEach(async () => { await orm.schema.clearDatabase() }) afterAll(() => orm.close(true)) beforeEach(async () => { const germany = orm.em.create(Country, { name: 'Germany' }) orm.em.create(User, { name: 'John Doe', address: new Address('Main Street', 'Berlin', germany) }) await orm.em.flush() }) test('the country can be populated through the address of a user', async () => { const user = await orm.em.findOneOrFail(User, { name: 'John Doe' }, { populate: ['address.country'] }) expect(user.address.country.name).toBe('Germany') }) test('the users can be populated through the address of a country', async () => { const country = await orm.em.findOneOrFail(Country, { name: 'Germany' }, { populate: ['users'] }) expect(country.users[0].name).toBe('John Doe') // ❌ this one fails }) test('can init the user collection of a country', async () => { const country = await orm.em.findOneOrFail(Country, { name: 'Germany' }) await country.users.init() expect(country.users.isInitialized()).toBe(true) }) }) ```
