将对象返回为json时访问雄辩的关系

Question

I am currently building a JSON RESTful API with Laravel/Lumen and now trying to access model attributes that are being stored in the relationship of this model

// I also want to return User->roles
return User::find(1)->first();

Returns:

{
  "id": 2,
  "email": '...'
}

I actually found a way but that seems pretty much hacked and not clean

    // Get user
    $user = User::find($id)->first();

    // Make roles public
    $user->roles = $user->roles;

    // Return object
    return $user;

Returns:

{
  "id": 2,
  "email": '...',
  "roles": [
  ...
  ]
}

Is there a better way? Or is this kind of a security thing where you want to protect your data? But since you can access the relationship in php why shouldn't it be returned as json object?

Couldn't find something in the laravel documentation

Answer 1

您可以在关系中使用helper函数with例如：

user::find($id)->with('roles')->first()

Answer 2

The shortest syntax for this will be:

User::with('roles')->find($id);

There's no need to use first() in this case

Answer 3

尝试这个：

$user = User::with('roles')->where('id',  $id)->first();

Answer 4

public function show(User $user) {
        return $user->load('books');
}
