php - 无法添加或更新子行 'user_id'

Question

当我提交表单时，我可以在错误中看到除了“user_id”之外我的所有值都已传递:

('insert into `products` (`title`, `body`, `address`, `condition`, `quantity`, `price`, `bid_price`, `img_1`, `updated_at`, `created_at`)

但是缺少'user_id'，为什么？这是我的Product.php

protected $fillable = ['slug', 'title', 'body', 'user_id', 'price', 'bid_price', 'address', 'condition', 'quantity', 'img_1', 'img_2', 'img_3', 'img_4', 'views'];

Controller 中的功能:

public function storeAuction(AuctionSubmitRequest $request)
{   
    $product = Product::create($request->all());

    Auth::user()->product()->save($product);

    $request->file('img_1')->move(public_path('images'), $request->file('img_1')->getClientOriginalName());

    $data = $request->except(['img_1']);
    $data['img_1'] = public_path('images') . '/' . $request->file('img_1')->getClientOriginalName();

    $product->create($data);

    return redirect('/');

}

您可以尝试以下操作。

public function storeAuction(AuctionSubmitRequest $request)
{
    $request->file('img_1')->move(public_path('images'), $request->file('img_1')->getClientOriginalName());

    // first create the related model, do not save or create 
    // because you will get a 'Cannot add or update a child row'
    $product = new Product();
    $product->property1 = $request->get('property1');
    $product->property2 = $request->get('property2');
    // ...
    $product->img_1 = public_path('images') . '/' . $request->file('img_1')->getClientOriginalName();

    // here you save a product associated to the user.
    Auth::user()->product()->save($product);

    return redirect('/');

}
