调用数组的成员函数 links()
Call to a member function links() on array
我正在使用 Laravel 8 和 Livewire。
我创建它是为了显示项目列表，用户也可以应用过滤器。加载后显示数据，每页 10 条记录。
但是，当我尝试单击下一页或特定页码时，出现错误“调用数组上的成员函数 links()...”
我也在使用存储库并将其注入 livewire 组件。
use App\Models\Repositories\Interfaces\LojaAdesaoRepositoryInterface;
use Livewire\Component;
use Livewire\WithPagination;
This is my component

将此从 mount 移至 render 方法：

说明
请注意您的两个方法 mount 和 render，虽然在组件启动时会调用一次 mount，但每次服务器调用都会调用 render。因此，当您以某种方式更改页面时，只会调用渲染并且 $lojas = $this->getLojas(); returns 它的初始值是一个空数组。
