如何在拉雷维尔建立多对多的关系

// the ticket migration 
Schema::create('tickets', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('user_id')->unsigned();
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->string('title');
    $table->text('body');
    $table->timestamps();
});

// ticket and status 
Schema::create('statuses', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->timestamps();
});

Schema::create('ticket_status', function (Blueprint $table) {    
    $table->integer('ticket_id')->unsigned();
    $table->integer('status_id')->unsigned();
    $table->primary(['ticket_id','status_id']);    
});

// store method
public function store()
{   
    $this->validate(request(), [
        'title' => 'required',
        'body' => 'required |min:5'
    ]);

    auth()
        ->user()
        ->tickets()
        ->create(request(['title','body','group','status','priority']));

    return redirect('/');
}

我要移民去买票 status_id 和 ticket_id .

create 方法在我的控制器中 table status_ticket 不要填充数据。

我没有错误,但我的表是空的。
