How to solve Missing argument 1 for App\\Repositor

问题:

My service is like this :

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

My repository is like this :

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

There exist error :

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

Can you help me?

UPDATE

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,
    ];
}

回答1:

Seems like you are using this pakage: nilportugues/eloquent-repository

If that is the case then you need to change the repository code to this:

public function delete($store_id)
{
    return $this->remove($store_id);
} 

回答2:

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
