Laravel 5.2調用未定義的方法Illuminate \ Database \ Query \ Builder :: activateTask（）

我是一個使用laravel的新手，在將代碼從路由更改爲控制器後出現問題。Laravel 5.2調用未定義的方法Illuminate Database Query Builder :: activateTask（）

當我將它們放置在routes.php中時，所有代碼都工作正常，但是當我將此代碼放入控制器Task.php中的函數並將函數函數添加到routes.php時，出現以下錯誤 - >

});

問題發生。

試圖谷歌的問題，並嘗試不同的方法來解決這個問題，但沒有運氣。我非常確定這是一件非常容易和愚蠢的事情，但無法弄清楚。

您的路線設置不正確。要使用控制器，請以[email protected]格式傳遞字符串作爲第二個參數。所以，你的路線應該是這樣的：

Route::post('/task/{task}/activate', '[email protected]');

而且，你的控制器的方法是希望傳遞的值是模型，而不是一個ID，所以你要輸入提示您的參數，以利用隱式模型綁定：

public function activateTask(\App\Task $task) { 
    // 
}

您可能需要查看routing documentation以獲取更多信息。

非常感謝！我試圖從文檔中找出。我只是不明白變量是如何通過路由的......但它似乎是自動執行的，如果你在函數中請求它的話？插件使用App/Session到任務控制器後開始工作。有更多的問題，但希望可以自己游泳徹底。 –
