Question

出什么问题了？我在数据库中有记录。

资源路线为Route::resource('dylan_dog', 'DylanDogController');

我在$dylan_dog中循环了由控制器（在下面提供）的每个index.blade.php记录，如下所示：

@foreach ($dylan_dog as $ddog)
        <tr>
          <td>{{ $ddog -> id }}</td>
          <td>{{ $ddog -> name }}</td>
          <td>{{ $ddog -> title }}</td>
          <td>{{ $ddog -> biography }}</td>
          <td><a href="{{ route('dylan_dog.edit', $dylan_dog->id) }}" class="btn btn-primary">Edit</a></td>
          <td>
            <form action="{{ route('dylan_dog.destroy', $dylan_dog->id) }}" method="post">
              @csrf
              @method('DELETE')
              <button class="btn btn-danger" type="submit" name="delete">Delete</button>
            </form>
          </td>
        </tr>
      @endforeach

有什么收获？

      $dylan_dog->delete();

      return redirect('/dylan_dog')->with('success', 'Character has been deleted successfuly');
    }

}

错误消息“ ErrorException（E_ERROR）属性[id]不存在在这个集合实例上。（视图： C：\ xampp \ htdocs \ miljan \ resources \ views \ dylan_dog \ index.blade.php）“

Answer 1

仅注意到您正在使用$dylan_dog->id。 $dylan_dog是Collection，并且没有id作为属性。请将其更改为$ddog->id：

<td><a href="{{ route('dylan_dog.edit', $ddog->id) }}" class="btn btn-primary">Edit</a></td>
      <td>
        <form action="{{ route('dylan_dog.destroy', $ddog->id) }}" method="post">
          @csrf
          @method('DELETE')
          <button class="btn btn-danger" type="submit" name="delete">Delete</button>
        </form>
      </td>

您还应该将路线参数更改为$ dogg。
