Laravel 5.2 调用未定义的方法 Illuminate\Database\Query\Builder::activateTask()

Question

我是一个使用 laravel 的新手，在将代码从路由更改为控制器后遇到了问题。

当我将它们放在 routes.php 中时，所有代码都运行良好，但是当我将此代码放入控制器 Task.php 中的函数并将函数函数添加到 routes.php 时，我收到以下错误 ->

我的任务控制器Task.php ->

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;

class Task extends Controller
{
    //

    public function activateTask($task)
    {
        if($task->active == 1)
        {
            return redirect('/');
        }
        else
        {
            $task->active = 1;
            $task->save();
            if(Session('active') != null)
            {
                $oldtask = App\Session::find(Session('active'));
                $oldtask->Task->active = 0;
                $oldtask->Task->save();
                $oldtask->touch();
                $oldtask->save();
            }
            $session = new Session;
            $session->task()->associate($task);
            $session->save();
            Session(['active' => $session->id]);
            return redirect('/');
        }
    }

    public function saveTask($request) {

        $validator = Validator::make($request->all(), [
            'name' => 'required|max:255',
        ]);

        if($validator->fails()) {
            return redirect('/')->withInput()->withErrors($validator);
        }

        $task = new Task;
        $task->name = $request->name;
        $task->deadline = $request->deadline;
        $task->save();
    }

}

任务模型Task.php ->

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Task extends Model
{
    //
    public function sessions()
    {
        return $this->hasMany('App\Session');
    }
}

会话模型Session.php ->

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Session extends Model
{
    //

    public function task()
    {
        return $this->belongsTo('App\Task');
    }

}

routes.php ->

<?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', function (Request $request) {
        Task::saveTask($request);
    /*

        $task->name = $request->name;
        $task->deadline = $request->deadline;
        $task->save();


    */
        return redirect('/');
    });



    Route::post('/task/{task}/activate', function (Task $task) {
        Task::activateTask($task);
    });



    Route::post('/task/{task}/deactivate', function (Task $task) {
        $task->active = 0;
        $task->save();
        $session = App\Session::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('/');

    });

    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('/');
    });

});

当我按下按钮发布到路线时发生问题。

试图用谷歌搜索这个问题并尝试了不同的方法来解决这个问题，但完全没有运气。我很确定这是一件非常简单和愚蠢但无法弄清楚的事情。

您的路线设置不正确。要使用控制器，您需要以controller@method 格式传递一个字符串作为第二个参数。所以，你的路线应该是这样的：

Route::post('/task/{task}/activate', 'Task@activateTask');

此外，您的控制器方法期望传入的值是模型，而不是 id，因此您需要键入提示您的参数以利用隐式模型绑定：

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

您可能需要查看routing documentation 以了解更多信息。
