Laravel Livewire 从字符串中获取关系数据

Question

我正在创建一个动态呈现数据的 Livewire 数据 table 组件。但是我在渲染关系数据时遇到了一些问题。

Subscription.php (Model)
class Subscription extends Model
{
    ...
    public function user()
    {
        return $this->belongsTo('App\Models\User');
    }
}

LivewireComponent.php
class SubscriptionTable extends Component
{
    ...
    public $columns =[
       [
          "name" => "User ID",
          "field" => "user_id",
          "sortable" => false, 
       ],
       [
          "name" => "Owner",
          "field" => null,
          "sortable" => false,
          "relation" => "user->name"
       ]
    ];
}     

livewire-component.blade.php:
...
@if(isset($columns['relation']))
   {{ dd($subscription->{$columns['relation']}) }} //return null
@else
   {{ dd($subscription->{$columns['field']}) }} //return User model
@endif

是否有任何解决方案或任何变通方法来检索用户名？

您可以使用 data_get 从关系中获取数据。

class SubscriptionTable extends Component
{
    ...
    public $columns =[
       [
          "name" => "User ID",
          "field" => "user_id",
          "sortable" => false, 
       ],
       [
          "name" => "Owner",
          "field" => null,
          "sortable" => false,
          "relation" => "user.name"
       ]
    ];
} 

livewire-component.blade.php:
...
@if(isset($columns['relation']))
   {{ dd(data_get($subscription,$columns['relation'])) }}
   // with get the value like $subscription['user']['name']
  // you can also pass the 3rd argument as default value
@else
   {{ dd($subscription->{$columns['field']}) }} //return User model
@endif
