我如何修复 Illuminate\Database\Eloquent\Collection 类的错误对象无法转换为 int

Question

我的页面应该显示来自不同表格的总和。当我尝试用代码求和时：

        $games = Game::where('winner_id', $user->id)->get();
        $games_low = GameLow::where('winner_id', $user->id)->get();
        $wins = $games + $games_low->count();
        $wins = $wins;
        $totalBank = $games->sum('price');

我收到错误Object of class Illuminate\Database\Eloquent\Collection could not be converted to int。我该如何解决这个问题？

Answer 1

问题 - 集合

将 + 用于对象 ($games) 和数字 ($games_low->count()) 导致错误。

$games     = Game::where('winner_id', $user->id)->get(); // Collection
$games_low = GameLow::where('winner_id', $user->id)->get(); // Collection

$games_low->count() // int

解决方案

将count 用于Game 和GameLow

$games     = Game::where('winner_id', $user->id)->count();
$games_low = GameLow::where('winner_id', $user->id)->count();
$wins      = $games + $games_low;

dd($wins);

如何正确显示变量的总和？在我有一个变量之前，我使用了$totalBank = $games->sum('price'); 我现在需要如何显示总和$games 和$games_low，我不知道

$games     = Game::where('winner_id', $user->id);
$games_low = GameLow::where('winner_id', $user->id);
$wins      = $games->count() + $games_low->count();
$totalBank = $games->sum('price');
