I'm new to NestJS (I had a bit of experience in Angular). I'm getting undefined
when I console.log a JoinTable (the tables are new. I'm tasked to create a new microservice)
So Unit
and Hub
has One to One
relationship.
Here is the unit
@Entity({
name: 'units',
})
export class UnitEntity {
@PrimaryGeneratedColumn()
id: number;
@OneToOne(() => HubEntity)
@JoinColumn({name: "hub_id"})
hub: HubEntity;
FYI I also tried coding it like this:
@OneToOne(type => HubEntity, hub => hub.unit)
@JoinColumn({name: "hub_id"})
hub: HubEntity;
For the HUB:
@Entity({
name: 'hubs',
})
export class HubEntity {
@PrimaryGeneratedColumn()
id: number;
@OneToOne(type => UnitEntity, unit => unit.hub)
@JoinColumn({name: "hub_id"})
unit: UnitEntity;
For testing, this is how I consoled it.
async findAllByUnit(unitId: number) {
const unit = await this.unitRepository.findOne(unitId)
console.log(unit.hub)
}
It returns undefined
Please let me know what I'm missing.
Thank you in advance~

You have to include the relationship like this:
await this.unitRepository.findOne(unitId, {
relations: ['hub']
})
