有一个问题，我在网络上的任何地方都找不到。错误通知我 save（） 方法没有退出？想不通问题所在。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 ->

任务.php控制器保存任务方法 ->
<?php
namespace App'Http'Controllers;
use Illuminate'Http'Request;
use Validator;
use App'Http'Requests;
use App'Http'Controllers'Controller;
use App'Session as Ticket;
use Session;
class Task extends Controller
{
//
public function activateTask('App'Task $task)
{
if($task->active == 1)
{
return redirect('/');
}
else
{
$task->active = 1;
$task->save();
if(Session('active') != null)
{
$oldtask = Ticket::find(Session('active'));
$oldtask->Task->active = 0;
$oldtask->Task->save();
$oldtask->touch();
$oldtask->save();
}
$session = new Ticket;
$session->task()->associate($task);
$session->save();
Session(['active' => $session->id]);
return redirect('/');
}
}
public function saveTask(Request $request) {
$validator = Validator::make($request->all(), [
'name' => 'required|max:255',
]);
if($validator->fails()) {
return redirect('/')->withInput()->withErrors($validator);
}
$task = new Task;
$task->name = $request->input('name');
$task->deadline = $request->input('deadline');
$task->save();
return redirect('/');
}
public function deactivateTask('App'Task $task)
{
$task->active = 0;
$task->save();
$session = Ticket::find(Session('active'));
$session->touch();
$started = strtotime($session->created_at);
$ended = strtotime($session->updated_at);
$hours = abs(($ended - $started))/(60*60);
$session->hours = $hours;
$session->save();
Session(['active' => null]);
return redirect('/');
}
}
路线 ->
<?php
use App'Task;
use App'Session;
use Illuminate'Http'Request;
Route::group(['middleware' => ['web']], function () {
//
Route::get('/', function() {
$task = Task::orderBy('created_at', 'desc')->get();
return view('layouts/tasks', [
'tasks' => $task
]);
});
Route::post('/task', 'Task@saveTask');
Route::post('/task/{task}/activate', 'Task@activateTask');
Route::post('/task/{task}/deactivate', 'Task@deactivateTask');
Route::delete('/task/{task}', function (Task $task){
if($session = Session::find(Session('active')))
{
if($session->task->id == $task->id)
{
Session(['active', null]);
}
}
$task->delete();
return redirect('/');
});
});
希望得到一些帮助。
您有两个名为 Task 的类，这没关系，因为它们位于不同的命名空间中。
首先，你有你的Task模型，它是'App'Task .其次，你有你的Task控制器，它是 'App'Http'Controllers'Task .
在任务控制器的saveTask方法中，有以下行：
$task = new Task;
由于未指定完全限定的类名，因此它将在当前命名空间中查找要使用的类。由于你位于 'App'Http'Controllers 命名空间中，因此它将创建一个新的'App'Http'Controllers'Task实例。
您需要将该行更改为：
$task = new 'App'Task;
您面临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，代码引用控制器任务，而不是模型任务。因此，它正在任务控制器类中搜索保存方法，而不是模型。您可以将其更改为
$task = new 'App'Task;
