我建立一个工作报价网站作为我在拉雷维尔学习的一部分。该网站允许交易人员添加用于工作的材料。用户在必要的表单字段中添加所有信息，如名称、工作描述等，以添加我使用的可以动态添加新行的滑块。
添加行，然后使用create/store方法提交表单。如果用户决定要编辑表单，则将从数据库中显示任何材质项。我和（quoteitem）belongsto和（quote）hasmany使用了雄辩的关系。我遇到的问题是，如果用户希望添加新行或编辑现有行，如何在submit上存储这些信息。我尝试了updateorcreate方法，但它不允许重复数据，用户可以决定添加相同的项目两次。我可以使用仅附加到现有行的id进行更新，但不能存储任何其他行。有没有办法做到这一点？任何帮助都将不胜感激。

// Quote controller

        $user = Auth::user();
        $date = Carbon::now()->format('j F Y');
        return view('quotes.edit', compact('quote', 'date', 'user'));
}

public function update(Request $request, Quote $quote){
