如何在Laravel 6中编辑旋转表复选框数据？

php artisan make:migration create_items_table --create=items

public function up()
{
    Schema::create('items', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->string('options')->nullable();
        $table->timestamps();
    });
}

php artisan migrate

php artisan make:model Item

namespace App;

use Illuminate\Database\Eloquent\Model;

class Item extends Model
{
    protected $fillable = ['name', 'options'];

    public function getOptionsAttribute($value)
    {
        return explode(',', $value);
    }

    public function setOptionsAttribute($value)
    {
        $this->attributes['options'] = implode(',', $value);
    }
}

php artisan make:controller ItemController

namespace App\Http\Controllers;

use App\Item;
use Illuminate\Http\Request;

class ItemController extends Controller
{
    public function edit($id)
    {
        $item = Item::findOrFail($id);
        return view('items.edit', compact('item'));
    }

    public function update(Request $request, $id)
    {
        $item = Item::findOrFail($id);
        $item->update($request->all());
        return redirect()->route('items.index');
    }
}

resources/views/items/edit.blade.php

<form action="{{ route('items.update', $item->id) }}" method="POST">
    @csrf
    @method('PUT')
    <div class="form-group">
        <label for="name">Name</label>
        <input type="text" name="name" id="name" value="{{ $item->name }}" class="form-control">
    </div>
    <div class="form-group">
        <label for="options">Options</label>
        @foreach(['Option 1', 'Option 2', 'Option 3'] as $option)
            <div class="form-check">
                <input type="checkbox" name="options[]" id="{{ $option }}" value="{{ $option }}" class="form-check-input" {{ in_array($option, $item->options) ? 'checked' : '' }}>
                <label for="{{ $option }}" class="form-check-label">{{ $option }}</label>
            </div>
        @endforeach
    </div>
    <button type="submit" class="btn btn-primary">Save</button>
</form>

Route::resource('items', 'ItemController');
