Laravel - 用户有很多画廊 - 画廊有很多图片 -> 如何插入数据库
Laravel - user has many galleries - gallery has many images -> how to insert in DB
用户模型：
public function galleries()
{
return $this->hasMany(Gallery::class);
}
图库模型：
public function images()
{
return $this->hasMany(Image::class);
}
现在在我的图像控制器中，我想将数据写入数据库。尝试了以下代码，但它不起作用。 （我没有收到错误，因为它是通过 dropzone 调用的...我在 dropzone 中看到的只是一个 X 和一个写有 [object Object]
的气泡
auth()->user()->galleries()->images()->create([
'gallery_id' => $gallery->id,
'filename' => $fileName,
'filesize' => $filesize,
'delete' => false,
]);
如何解决？

推荐： 你有 $gallery_id 所以这可以工作：
//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：用gallery_id正常插入图片（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 class 的顶部。
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，但您需要一个画廊与新图像相关联，
用户模型：
public function galleries()
{
return $this->hasMany(Gallery::class);
}
图库模型：
public function images()
{
return $this->hasMany(Image::class);
}
现在在我的图像控制器中，我想将数据写入数据库。尝试了以下代码，但它不起作用。 （我没有收到错误，因为它是通过 dropzone 调用的...我在 dropzone 中看到的只是一个 X 和一个写有 [object Object]
的气泡 auth()->user()->galleries()->images()->create([
'gallery_id' => $gallery->id,
'filename' => $fileName,
'filesize' => $filesize,
'delete' => false,
]);
如何解决？
