未定义的属性

Question

我试图在我的模型上创建一个CRUD，但我收到了这个错误：

未定义属性：App \ Http \ Controllers \ MarketingChannelController :: $ MarketingChannelRepository

在这个功能上：

 public function edit($id)
    {
        //

        return view('MarketingChannel.create', [
            'MarketingChannel' => $this->MarketingChannelRepository->getMarketingChannel($id),
        ]);
    }

这是我的MarketingChannelRepository：

<?php

namespace App\Repositories;

use App\MarketingChannel;

class MarketingChannelRepository
{
    /**
     * Get all of the tasks for a given user.
     *
     * @param  User  $user
     * @return Collection
     */
    public function allMarketingChannels()
    {
        return MarketingChannel::orderBy('id', 'asc')
                    ->get();
    }

    public function getMarketingChannel($id)
    {
        return MarketingChannel::where('id', $id)
                    ->orderBy('id', 'asc')
                    ->get();
    }

}

?>

Answer 1

Controller需要存储库变量。

示例：

class MarketingChannelController extends Controller{
    protected $MarketingChannelRepository;

    public function __construct(MarketingChannelRepository $MarketingChannelRepository){
     $this->MarketingChannelRepository = $MarketingChannelRepository;
    }
    public function edit($id)
    {


        return view('MarketingChannel.create', [
        'MarketingChannel' => $this->MarketingChannelRepository->getMarketingChannel($id),
    ]);
    }
}
