I created an API in laravel where fetch all data in the users table from my controller
class UserApiController extends Controller
{
public function index()
{
return Users::all();
}
}

fruit_id: B456,
name: Mary,
gender: Female,
},

Answer 1

You should create a relationship inside Model\User. Then, you can use with() or load().
Example:
Users::all()->load('fruits');

Answer 2

you need to make one-to-many relationship between tables
table->users
Id - Name - Gender
table->fruits
Id - user_id - Name - Quantity
class User extends Model{
public function fruits(){
return $this->hasMany(Fruit::class,'user_id');
}
}
class Fruit extends Model{
public function user(){
return $this->belongsTo(User::class,'user_id');
}
}
User::with('fruits')->get();
