php – 如何在Laravel 5.4中播放数据透视表？

Laravel 4 faker类播种和laravel 5.4之间有不同的编码.

我仍然遵循教程“Seeders Reloaded”中的相同代码行.现在,我被困在“Class LessonTagTableSeeder不存在”

TagTableSeeder

class TagsTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {

        $faker = Faker::create('AppTag');

        for($i=1; $i <= 10; $i++) {

            DB::table('tags')->insert([
                'name' => $faker->word,'created_at' => CarbonCarbon::now(),'updated_at' => CarbonCarbon::now(),]);


        }


    }

LessonTagTableSeeder

use IlluminateDatabaseSeeder;
use FakerFactory as Faker;
use AppLesson;
use AppTag;

class LessonTagTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {

        $faker = Faker::create();

        $lessonIds = Lesson::pluck('id')->all();
        $tagIds = Tag::pluck('id')->all();

        for($i=1; $i <= 30; $i++) {

            DB::table('lesson_tag')->insert([
                'lesson_id' => $faker->randomElement($lessonIds),'tag_id' => $faker->randomElement($tagIds)
            ]);


        }


    }

DatabaseSeeder

use IlluminateDatabaseSeeder;
use IlluminateDatabaseEloquentModel;
use AppLesson;
use AppTag;
use DB;

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {

        DB::statement('SET FOREIGN_KEY_CHECKS=0');
        Lesson::truncate();
        Tag::truncate();
        DB::table('lesson_tag')->truncate();

        Model::unguard();

        $this->call('LessonsTableSeeder');
        $this->call('TagsTableSeeder');
        $this->call('LessonTagTableSeeder');

        DB::statement('SET FOREIGN_KEY_CHECKS=1');

    }

我能够使用php artisan db：seed –class = TagsTableSeeder播种TagsTableSeeder

当我运行“php artisan db：seed –class = LessonTagTableSeeder”时,系统会提示我：

[ReflectionException]
Class LessonTagTableSeeder不存在

你知道如何编辑上面的代码吗？任何帮助表示赞赏
