public function voteToPost(Request $request)
{
    $userid = $request->user()->id;
    $postid = $request->get('post_id');
    $vote = $request->get('vote');
    $votecount = DB::table('votes')->where('user_id', $userid)->where('post_id', $postid)->wherea('hide', 0)->count();
    if($votecount == 0){
        DB::table('votes')
            ->leftJoin('users', 'users.id', '=', 'votes.user_id')
            ->leftJoin('posts', 'posts.id', '=', 'votes.post_id')
            ->where(['votes.hide' => 0, 'votes.user_id' =>$userid, 'votes.post_id' =>$postid])
            ->updateOrInsert([
                'user_id' => $userid,
                'post_id' => $postid,
                'vote' => $vote,
                'hide' => 0,
                'created_at' => Carbon::now(),
                'updated_at' => Carbon::now()
            ]);
    }
}

我收到以下錯誤“消息”：“SQLSTATE [23000]：完整性約束違規：1052列‘隱藏’在where子句是曖昧（SQL：選擇存在（SELECT * FROM votes左加入users的users 。 id = votes 。 user_id左連接posts上posts 。 id = votes 。 post_id其中（ votes 。 hide = 0和votes 。 user_id = 3和votes 。 post_id = 6）和（ user_id = 3和post_id = 6和vote = 1和hide = 0和created_at = 2018-10-05 11:44:38和updated_at = 2018-10-05 11:44:38）） exists ）“，

public function voteToPost(Request $request){
        $userid = $request->user()->id;
        $postid = $request->get('post_id');
        $vote = $request->get('vote');
        $user = User::where(['id'=>$userid, 'hide'=>0])->first();
        $post = DB::table('posts')->where(['id'=>$postid, 'hide'=>0])->first();
        if($user && $post && in_array($vote, [0,1,-1])){
                DB::table('votes')
                    ->updateOrInsert(['user_id'=>$userid, 'post_id'=>$postid],[
                        'user_id' => $userid,
                        'post_id' => $postid,
