当我尝试获取一个产品并对其执行命令时，我会得到“Illuminate\Database\QueryException SQLSTATE[23000]：完整性约束冲突：1048数据行'name'不可以是空值（SQL：insert into commande（name，familyname，quantity，mobile，ville，adresse，id_product，user_id，updated_at，created_at）values（？，？，？，？，？，？，？，？，2022 - 11 - 21 21：30：27，2022 - 11 - 21 21：30：27））”我在这里尝试命令一个产品，其中每个产品都有不同的用户。我在产品表（user_id）中使用外键，并且每个命令都有一个用户来检查它。
这是我在控制器中的函数：

public function getProduct($id, Request $request)
{

    $product = Product::find($id);
    $commande = new AppCommande;
    $commande->name = $request->input('name');
    $commande->familyname = $request->input('familyname');
    $commande->quantity = $request->input('quantity');
    $commande->mobile = $request->input('mobile');
    $commande->ville = $request->input('ville');
    $commande->adresse = $request->input('adresse');
    $commande->id_product = $request->input('id_product');
    $commande->user_id = $request->input('id_user');
    $commande->save();
    return view('product', ['product' => $product], ['commande' => $commande]);

}

这是我的路线：

Route::get('/product/{id}', \[ 'uses' =\> 'CommandeUserController@getProduct', 'as' =\> 'product.single' \]);

这是一个视图：

@extends('layouts.app')
@section('content')

    <div class="col-sm-6 col-md-4">
        <div class="thumbnail">
            <img src="{{ asset('uploads/product/'.$product->image) }}" width="90px" alt="image">
