Laravel - 用户有很多画廊 - 画廊有很多图片 -> 如何插入数据库

Question

用户模型：

public function galleries()
{
    return $this->hasMany(Gallery::class);
}

画廊模型：

public function images()
{
    return $this->hasMany(Image::class);
}

现在在我的图像控制器内部，我想将数据写入数据库。尝试了以下代码，但它不起作用。 （我也没有收到错误，因为它是通过 dropzone 调用的...我在 dropzone 内看到的只是一个 X 和一个带有 [object Object] 的气泡

 auth()->user()->galleries()->images()->create([
                'gallery_id' => $gallery->id,
                'filename' => $fileName,
                'filesize' => $filesize,
                'delete' => false,
            ]);

如何解决这个问题？

编辑：来自日志

如果我删除上面的行，错误就会消失..

Answer 1

推荐：您有$gallery_id，所以这可行：

//get gallery object
$gallery = auth()->user()->galleries()->findOrFail($gallery->id);

//build image object
$image = new Image;
$image->filename = $fileName;
$image->filesize = $filesize;
$image->delete = false;

//assosiate image to it's gallery
$gallery->images()->save($image);

简单方法：正常插入图片，带gallery_id（这个方法不太好，因为你不知道this_gallery_id是不是this_authenticated_user）：

$image=Image::create([
            'gallery_id' => $gallery->id,
            'filename' => $fileName,
            'filesize' => $filesize,
            'delete' => false,
        ]);

别忘了use App/Image; 在班级顶部。

您的代码不起作用，因为当您获得user()->galleries() 时，您会在一个对象中获得该用户的所有画廊，但是您需要一个画廊来关联新图像，
