Controller.php中的BadMethodCallException行103：方法[保存]不存在

Question

有問題我無法在網上找到任何地方。錯誤通知我save（）方法不存在？不能弄明白這個問題。發送郵件表單以在控制器中創建/保存新任務時會發生此問題。

跟蹤堆棧和錯誤的方法如下 - >

很想得到一些幫助。

Answer 1

你所面對的問題是，你命名你的控制器任務和你正在做的

$task = new Task; 

在這種情況下，代碼是指控制器的任務，但不是模型的任務。所以它在Task控制器類中搜索save方法，而不是模型。你可以把它改成

$task = new \App\Task; 

Answer 2

您有一個名爲Task兩個類，因爲它們是在不同的命名空間是好的。

首先，你有你的Task模型，這是\App\Task。其次，你有你的Task控制器，它是\App\Http\Controllers\Task。

在你的任務控制器，在你saveTask方法，你有下面這行：

$task = new Task; 

因爲你沒有指定完整的類名，它看起來在當前名字空間的類使用。由於您位於\App\Http\Controllers名稱空間中，因此它正在創建一個新的\App\Http\Controllers\Task實例。

您需要更改行：

$task = new \App\Task;
