我想投票或其他人张贴的帖子。用户将上传帖子，i

迁移到投票表

public function up()
{
    Schema::create('votes', function (Blueprint $table) {
        $table->increments('id');
        $table->unsignedInteger('user_id');
        $table->foreign('user_id')->references('id')->on('users');
        $table->unsignedInteger('post_id');
        $table->foreign('post_id')->references('id')->on('posts');
        $table->integer('vote');
        $table->boolean('hide')->default(0);
        $table->timestamps();
    });
}

路由文件

api.php

Route::group(['middleware'=>[
                'auth:api', \App\Http\Middleware\OnlyRegisteredUsers::class]
            ], function(){
    /**
     * Group for registered users only APIs
     */
    Route::post('saveMedia','UserController@saveMedia');
    Route::post('voteToPost','UserController@voteToPost');
});

控制器

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()
            ]);
    }
}

我遇到以下错误 “ message”：“ SQLSTATE [23000]：违反完整性约束：1052 where子句中的列'hide'不明确（SQL：select exist（select * from votes在{{1}上左联接users }。users = id。votes在user_id上左加入posts。posts = id。votes其中（post_id。votes = 0和hide。votes = 3和user_id。votes = 6）和（{{1} } = 3且post_id = 6且user_id = 1且post_id = 0且vote = 2018-10-05 11:44:38和hide = 2018-10-05 11:44:38））为created_at）“，

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,
                        'vote' => $vote,
                        'hide' => 0,
                        'created_at' => Carbon::now(),
                        'updated_at' => Carbon::now()
                    ]);
                return ['message'=>'ok'];
        }
        return abort(403, 'Invalid request');
    }
