Laravel 5：Container.php第734行中的ReflectionException：类任务不存在错误

Question

我是laravel的新手，我遇到了这个问题。我正在尝试创建一个任务列表，用户可以在其中创建，编辑和删除任务。 我在尝试编辑任务时发生错误。当我点击＆＃34;编辑＆＃34;按钮，显示：

ReflectionException in Container.php line 734:
Class Task does not exist
in Container.php line 734
at ReflectionClass->__construct('Task') in Container.php line 734
at Container->build('Task', array()) in Container.php line 629
at Container->make('Task', array()) in Application.php line 697
at Application->make('Task') in Router.php line 993

这是我的控制器类：

TasksController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use Input;
use Redirect;
use App\Task;

class TasksController extends Controller
{
    public function home()
    {
        $tasks = Task::all();

        return view('home', compact('tasks'));
    }

    public function create()
    {
        return view('create');
    }

    public function edit(Task $task)
    {
        return view('edit', compact('task'));
    }

    public function delete()
    {
        return view('delete');
    }

    public function saveCreate()
    {
        $input = Input::all();

        $task = new Task;
        $task->title = $input['title'];
        $task->body = $input['body'];
        $task->save();

        return Redirect::action('TasksController@home');
    }

    public function doEdit()
    {
        $task = Task::findOrFail(Input::get('id'));
        $task->title = Input::get('title');
        $task->body = Input::get('body');
        $task->done = Input::get('done');
        $task->save();

        return Redirect::action('TasksController@home');
    }
}

这是我的路线档案：

<?php
Route::model('task', 'Task');
Route::get('/', 'TasksController@home');
Route::get('/create', 'TasksController@create');
Route::get('/edit/{task}', 'TasksController@edit');
Route::get('/delete', 'TasksController@delete');

Route::post('/create', 'TasksController@saveCreate');
Route::post('/edit', 'TasksController@doEdit');
?>
