Laravel5中的一對多關系無法正常工作

[英]one to many relationship in Laravel5 is not working properly

我有一個收集控制器

看起來像這樣

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Middleware\Role;
use Illuminate\Support\Facades\Input;
use App\User;
use App\Invoice;
use Session;
use Validator;


class CollectionController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */

  public function __construct(){

    $this->middleware('role:collector'); // replace 'collector' with whatever role you need.
}
   public function getPayment($invoiceid){


         $id =$invoiceid;
         $invoice=Invoice::where('Id', $id)->with(['payments'])->get();


         return View('collectionmodule/payment')->with(array('invoice'=>$invoice));

 }

}

然后我有以下型號發票

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Invoice extends Model
{
    //
     protected $table = 'event_invoice';

     public function payments(){
        return $this->hasMany('App\paymentrecieved','invoice_id');
    }

    public function comments(){
        return $this->hasMany('App\comments','invoice_id');
    }
}

Paymentrecieved

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class paymentrecieved extends Model
{
    //
    protected $table = 'paymentrecieved';

    public function invoice(){

            return $this->belongsTo('App\Invoice');

        }


}

因此,對於每個發票,可能會有多筆付款。

所以在我的getPayment方法中,我正在編寫這樣的查詢。

$invoice=Invoice::where('Id', $id)->with(['payments'])->get();

它從發票表中獲取詳細信息。 但它沒有給我任何付款細節

任何人都知道為什么會發生這種情況,據我說我已經正確地完成了這段關系

謝謝

您使用Id (使用大寫)作為主鍵,但Invoice模型正在查找id (使用小寫)。

您應該在Invoice模型中定義主鍵,如下所示:

protected $primaryKey = 'Id';
