Laravel 更新错误的模态

【问题描述】：

Laravel 正在更新错误的行 $winner_number is = 0，但它正在更新 selectedItem“绿色”。我不知道我在这里做错了什么。

// Laravel is updating wrong rows
$number_games = Game::where('period', $period)
    ->where('selectedItem', $winner_number)
    ->where('game_type_id', $game_type_id)->get();

// $number_games is empty but still its updating different modals 
foreach ($number_games as $number_game) 
    $number_game->received_amount = $number_game->bet_amount *
        $parameter->win_number_times;
    $number_game->status = "success";
    $number_game->save();

【参考方案1】：

我想忘了加上双引号。你在这里搜索一个字符串

$number_games = Game::where('period', $period)
    ->where('selectedItem', "$winner_number")
    ->where('game_type_id', "$game_type_id")->get();

foreach ($number_games as $number_game) 
    $number_game->received_amount = $number_game->bet_amount * $parameter->win_number_times;
    $number_game->status = "success";
    $number_game->save();

【参考方案2】：

我认为你可以在没有循环的情况下实现

$number_games = Game::where('period', $period)->where('selectedItem',
        $winner_number)
        ->where('game_type_id', $game_type_id)->update([
            'status'=>'success',
            'received_amount'=>DB::raw(vsprintf('bet_amount* %s',[$parameter->win_number_times]))
        ])

【讨论】：

SQLSTATE[22007]：无效的日期时间格式：1292 截断不正确的 DOUBLE 值：“紫罗兰色”（SQL：更新 games 设置 status = 成功，games.updated_at = 2021- 07-04 22:18:56 其中period = 20210704438 和selectedItem = 0 和game_type_id = 1)

@Ganeshrao 你能展示一下游戏模型和数据库表结构吗

我的模型 belongsTo(User::class); 公共函数 game_type() return $this->belongsTo(GameType::class); public function transaction() return $this->hasOne(Transaction::class);

Schema::create('games', function (Blueprint $table) $table->id(); $table->string('period'); $table->string(' selectedItem'); $table->string('total_amount'); $table->string('bet_amount'); $table->string('service_charge'); $table->string('received_amount')->可为空(); $table->string('status')->default('waiting');

$table->unsignedBigInteger('game_type_id'); $table->unsignedBigInteger('user_id'); $table->foreign('game_type_id')->references('id')->on('game_types')->onDelete('cascade'); $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade'); $table->timestamps();
