DB::table() method not found, laravel - development

DB::table() method not found, laravel

I researched the net, but couldnt find a solution to my problem.

I cant get an element from my database.

   <?php

namespace App;
use IlluminateSupportFacadesDB;
use IlluminateDatabaseEloquentModel;
use IlluminateSupportFacadesAuth;
class Wishlist extends Model
{
    public $table = 'wishlist';
    public $fillable = ['book_id','user_id',];

    public function books() //one-to-many
    {
        return $this->hasMany('AppBook');
    }

    public function user()
    {
        return $this->belongsTo('AppUser');
    }
    public static function myWishlist()   
    {
        $id = Auth::id();
        $wishlist = DB::table('users')->where('id', $id)->pluck('wishlist_id');
        $wishlist_id = User::where('id', $id)->pluck('wishlist_id'); 
        return Book::where('wishlist_id', $wishlist_id);
    }
}

If I fill in hard: ‘return Book::where(‘whishlist_id’, 1);’ it shows it correctly. But neither ‘wishlist’ nor ‘wishlist_id’ shows it.

I would be so happy to get help!
