Php 为foreach（）提供的laravel一对多无效参数

您好，我需要帮助来解决此问题。

我正试图让“一对多”关系的价值进入视野。但我得到错误“为foreach（）提供的参数无效”

供应商模型

<?php

namespace App;
use App\Purchase;
use Illuminate\Database\Eloquent\Model;

class Supplier extends Model
{
     
     protected $table = 'suppliers';
     protected $fillable = ['party_id','suppliers_master_id','suppliers_unic_id','supplier_name','email','phone','address','city','state','pincode','GSTIN','delete_status'];



        public function purchases()
{
    return $this->hasMany(Purchase::class, 'suppliers_master_id', 'suppliers_master_id');
}


}

控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use App\Supplier;
use App\Billproduct;
use App\Purchase;
use App\Item_list;
use Illuminate\Support\Facades\Auth;
class PurchaseController extends Controller
{
    /** 
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */

    public function purchaseentrylists($suppliers_master_id)
    { 
      
        $entry = Supplier::where('delete_status','!=','NOT_DELETED')->find($suppliers_master_id);
        return view('purchase.purchase-entry-list',compact('entry'));

    }


}

看法

SL号
账单号
账单日期
供应品名称
票据金额
@foreach（$key=>$entrys作为条目）
{{$key+1}}
{{$entrys->bill_no}
{{$entrys->bill_date}
{{$entrys->supplier_name}
{{$entrys->账单总额}
@endforeach

我想你忘了给外交部打电话了。 您需要调用：

$entry->purchases或$entry->purchases（）->get（）

来获取供应商的采购集合，然后可以对其进行迭代

<tbody>
 @foreach ($entry->purchases as $key=>$entrys)
                                 
            <td>{{ $key + 1  }}</td>
            <td>{{ $entrys->bill_no  }}</td>
            <td>{{ $entrys->bill_date }}</td>
            <td>{{ $entrys->supplier_name }}</td>
            <td>{{ $entrys->total_bill_amount }}</td>
@endforeach
 </tbody>

我不明白你能发布你的答案吗？我返回了“return Supplier:：find（$suppliers\u master\u id）->purchases”；这是我得到的值，但当我使用foreach时，它显示错误我修改了我的代码，作为你的答案。get error“尝试获取非对象的属性‘purchases’”，你可能需要使用findOrFail（）而不是find，或者处理找不到有效入口的情况。您能否在回答中更新公共函数purchaseEntryList（$suppliers\u master\u id）{$entry=Supplier:：where（'delete\u status'，'not\u DELETED'）->findOrFail（$suppliers\u master\u id）；返回视图（'purchase.purchase entry list'，compact（'entry'）；}谢谢
