Question

我尝试使用php slim在控制器中访问我的任务模型但是我遇到了这个错误

Too few arguments to function App\Models\Task::__construct(), 0 passed on line 26 and exactly one on TodoController.php

有什么建议吗？在此先感谢，我引用了类似的问题like this，但我无法将其与我所拥有的相关联。

最终我想从Task.php模型中提取方法，并在需要时在控制器中调用它。

TodoController.php

<?php


namespace App\Controllers;

use Slim\Http\Request;
use Slim\Http\Response;

use App\Models\Task;

class TodosController extends BaseController
{

    // public function getTodos($request, $response, $args)
    // {
    //  $sth = $this->db->prepare("SELECT * FROM tasks ORDER BY task");
    //  $sth->execute();
 //         $todos = $sth->fetchAll();

 //        return $this->c->view->render($response, 'todos.twig', ['todos' => $todos]);

    // }

    public function index()
    {
        $tasks = new Task();
        $tasks->getTodos();


    }

    public function deleteTodo($request, $response, $args)
    {
        $sth = $this->db->prepare("DELETE FROM tasks WHERE id=:id");
        $sth->bindParam("id", $args['id']);
        $sth->execute();
        $todos = $sth->fetchObject();
        $url = urlFor($todos);
        var_dump($url);
        return $this->response->withJson($todos)->withRedirect('/todos');


    }

如果这对我有帮助，那就是我的Task.php

<?php

namespace App\Models;


use Slim\Views\Twig as View;
use Interop\Container\ContainerInterface;

class Task
{

    protected $c;
    public $db;

    public function __construct(ContainerInterface $container)
    {
        $this->c = $container;
        $this->db = $container['db'];

    }

   public function getTodos($request, $response, $args)
    {
        $sth = $this->db->prepare("SELECT * FROM tasks ORDER BY task");
        $sth->execute();
        $todos = $sth->fetchAll();

        return $this->c->view->render($response, 'todos.twig', ['todos' => $todos]);

    }




}

我还查看了另一个类似的例子like this，但仍然无法理解我做错了什么。

Answer 1

public function index($req, $res, $args)
{
    $tasks = new Task($this->container);
    $tasks->getTodos($req, $res, $args);
}

函数App \ Models \ Task :: __ construct（）的参数太少，0在第26行传递，只有一个
