ManyToMany with private field

[mbayou]

Hi,

I try to create entity with relation many to many, but I want it on private field, so I created a getter.

/**     
 * User's circles     
 */     
@ManyToMany((type) => ActivityCircle, (activityCircle) => activityCircle.getUsers, {lazy: true})     
 private circles: ActivityCircle[];     

/**
   * Circle's users
   */
  @ManyToMany((type) => User, (user) => user.getCircles, {lazy: true})
  @JoinTable()
  private users: User[];

When I tried it an error occurred

{"message":"JoinTable is missing on User#circles many-to-many relationship. You need to put JoinTable decorator on it.","stack":"MissingJoinTableError: JoinTable is missing on User#circles many-to-many relationship. You need to put JoinTable decorator on it....

Do you have any solution to fix it ?

Thanks you.

no, you can't use getter. Just do:

  @ManyToMany((type) => User, "circles", {lazy: true})
  @JoinTable()
  private users: User[];

But first think if you really need getters (mistake #1 of users who come from java-like languages thinking they must use getters here as well).

Also instead of doing {lazy: true} here you should do private users: Promise<User[]> and note lazy relations is a very specific feature.

Thank you, it works ! I know the element of getter and setter but I have some constraints, however, really thank you for your quick response. :)
