Controller.php第103行中的BadMethodCallException：方法[save]不存在

Question

遇到问题我无法在网络上找到任何地方。错误通知我save（）方法没有退出？无法弄清楚问题所在。发送帖子表单以在控制器中创建/保存新任务时会发生此问题。

跟踪堆栈和错误方法如下 - ＆gt;

BadMethodCallException in Controller.php line 103: Method [save] does not exist.

希望得到一些帮助。

Answer 1

您有两个名为Task的类，这是可以的，因为它们位于不同的名称空间中。

首先，您拥有Task模型，即\App\Task。其次，您拥有Task控制器，即\App\Http\Controllers\Task。

在您的任务控制器中，在saveTask方法中，您有以下一行：

$task = new Task;

因为您没有指定完全限定的类名，所以它将在当前命名空间中查找要使用的类。由于您位于\App\Http\Controllers命名空间，因此它正在创建一个新的\App\Http\Controllers\Task实例。

您需要将行更改为：

$task = new \App\Task;

Answer 2

您遇到的问题是您将控制器命名为“任务”并且您正在执行

 $task = new Task;

在这种情况下，代码指的是控制器任务，但不是模型任务。所以它在Task控制器类中搜索save方法而不是模型。你可以把它改成

$task = new \App\Task;
