如何解决App \ Repositories \ FavoriteRepository :: delete()的缺少参数1? (Laravel 5.3) [英] How to solve Missing argument 1 for App\Repositories\FavoriteRepository::delete() ? (Laravel 5.3)

问题描述

我的服务是这样的:

public function delete($store_id)
{
    $result = $this->favorite_repository->delete($store_id);
    dd($result);
}

我的存储库是这样的:

public function delete($store_id)
{
    $data = self::where('favoritable_id', $store_id)->delete();
    return $data;
} 

存在错误:

缺少App \ Repositories \ FavoriteRepository :: delete()的参数1， 呼入 C:\ xampp \ htdocs \ mysystem \ app \ Repositories \ FavoriteRepository.php在 第45行并已定义

Missing argument 1 for App\Repositories\FavoriteRepository::delete(), called in C:\xampp\htdocs\mysystem\app\Repositories\FavoriteRepository.php on line 45 and defined

你能帮我吗?

更新

EloquentRepository中的删除功能如下:

The delete function in the EloquentRepository is like this :

public function delete($id)
{
    // Find the given instance
    $deleted  = false;
    $instance = $id instanceof Model ? $id : $this->find($id);

    if ($instance) {
        // Delete the instance
        $deleted = $instance->delete();

        // Fire the deleted event
        $this->getContainer('events')->fire($this->getRepositoryId().'.entity.deleted', [$this, $instance]);
    }

    return [
        $deleted,
        $instance,
    ];
}

推荐答案

您是否检查了哪个实例返回了您的self::where('favoritable_id', $store_id)?似乎它返回的是EloquentRepository实例，而不是Model实例. 区别在于EloquentRepository的 delete 方法是delete($id)，模型的 delete 方法是delete(). 因此，您要么需要获取Model实例以使用-> delete()，要么在您的模型上使用-> delete($ id)

Have you checked which instance is returning your self::where('favoritable_id', $store_id)? It seems it is returning your EloquentRepository instance, instead of Model instance. The difference is that EloquentRepository's delete method is delete($id), the Model's delete method is delete(). So you either need to get Model instance to use ->delete(), or use ->delete($id) on yours
