可以使用mount方法而不是render方法来执行初始化任务

class Test extends Component
{
    protected $model;
    protected $fields;
    protected $data;

    public function make(array $fields): static
    {
        $this->fields = $fields;
        return $this;
    }

    public function model($model)
    {
        $this->model = $model;
        if (!$this->query) {
            $this->query($this->model::query());
        }
        return $this;
    }

    public function mount()
    {
        // Perform initialization here
        $this->model($this->model)->make($this->fields);
    }

    public function render()
    {
        $this->ensureValidQuery();
        $this->data = $this->query->get();
        return view($this->view, get_object_vars($this));
    }
}

您可以创建并初始化测试组件

$test = (new Test())->model($this->model)->make([
    // Your fields here
]);
