/*检查此用户是否在该问题下投过票*/
$vote = $answer
   ->users()
   ->newPivotStatement()
   ->where('user_id',session('user_id'))
   ->where('answer_id',rq('id'))
   ->first();

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'xiaohu.answers_user' doesn't exist (SQL: select * from `answers_user` where `user_id` = 3 and `answers_id` = 1 limit 1)

这里 测试时 提示 answers_user 找不到。。 怎么是带s的  Migration

$table->increments('id');
$table->unsignedInteger('user_id');
$table->unsignedInteger('answer_id');
$table->unsignedSmallInteger('vote');
$table->timestamps();

$table->foreign('user_id')->references('id')->on('users');
$table->foreign('answer_id')->references('id')->on('answers');
$table->unique(['user_id','answer_id','vote']);

public function users()
{
   return $this
       ->belongsToMany('App\User')
       ->withPivot('vote')
       ->withTimestamps();
}

严格按老师 的视频 敲得代码。。 操作系统 是 ubuntu+homestead  laravel版本5.2.31
