Constructors

constructor

• new Reference<T>(entity: T): Reference<T>

• Type parameters

  • T: object

  Parameters

  • entity: T

  Returns Reference<T>

Methods

getEntity

• getEntity(): T

• Returns T

getProperty

• getProperty<K>(prop: K): T[K]

• Type parameters

  • K: string | number | symbol

  Parameters

  • prop: K

  Returns T[K]

isInitialized

• isInitialized(): boolean

• Returns boolean

load

• load<TT, P, F, E>(options?: LoadReferenceOptions<TT, P, F, E>): Promise<null | Loaded<TT, P, F, E>>

• Ensures the underlying entity is loaded first (without reloading it if it already is loaded). Returns the entity. If the entity is not found in the database (e.g. it was deleted in the meantime, or currently active filters disallow loading of it) the method returns null. Use loadOrFail() if you want an error to be thrown in such a case.

  Type parameters

  • TT: object
  • P: string = never
  • F: string = *
  • E: string = never

  Parameters

  • options: LoadReferenceOptions<TT, P, F, E> = {}

  Returns Promise<null | Loaded<TT, P, F, E>>

loadOrFail

• loadOrFail<TT, P, F, E>(options?: LoadReferenceOrFailOptions<TT, P, F, E>): Promise<Loaded<TT, P, F, E>>

• Ensures the underlying entity is loaded first (without reloading it if it already is loaded). Returns the entity or throws an error just like em.findOneOrFail() (and respects the same config options).

  Returns Promise<Loaded<TT, P, F, E>>

loadProperty

• loadProperty<TT, P, K>(prop: K, options?: LoadReferenceOrFailOptions<TT, P, *, never>): Promise<Loaded<TT, P>[K]>

• Type parameters

  • TT: object
  • P: string = never
  • K: string | number | symbol = keyof TT

  Parameters
