问题描述
您好，我需要帮助解决此问题。
我正在尝试获得“一对多”关系。但出现错误“为foreach（）提供了无效的参数”
供应商模型
<?PHP
namespace App;
use App\Purchase;
use Illuminate\Database\Eloquent\Model;
class @R_404_3996@ extends Model
{
protected $table = '@R_404_3996@s';
protected $fillable = ['party_id','@R_404_3996@s_master_id','@R_404_3996@s_unic_id','@R_404_3996@_name','email','phone','address','city','state','pincode','GSTIN','delete_status'];
public function purchases()
{
return $this->hasMany(Purchase::class,'@R_404_3996@s_master_id');
}
}
购买模型
<?PHP
namespace App;
use App\Purchase;
use Illuminate\Database\Eloquent\Model;
class Purchase extends Model
{
protected $table = 'purchases';
protected $fillable =
['@R_404_3996@s_master_id'，'@R_404_3996@s_unic_id'，'party_id'，'@R_404_3996@_name'，'GSTIN'，'bill_no'，'bill_date'，'bill_entry_date'，'total_bill_amount'，'phone'，'pincode'，'state '，'address'，'delete_status'，'part_no'];
}
控制器
<?PHP
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use App\@R_404_3996@;
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()
{
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function purchaseentrylists($@R_404_3996@s_master_id)
{
$entry = @R_404_3996@::where('delete_status','!=','NOT_DELETED')->find($@R_404_3996@s_master_id);
return view('purchase.purchase-entry-list',compact('entry'));
}
}
路线
Route::get('purchas/eentry/lists{id}','PurchaseController@purchaseentrylists')- >name('purchaseentrylists');
查看
<table id="example" class="table table-striped table-bordered" style="width:100%">
<thead>
<tr>
<th>SL-No</th>
<th>BILL NO</th>
<th>BILL DATE</th>
<th>SUPPLIES NAME</th>
<th>BILL AMOUNT</th>
</tr>
</thead>
<tbody>
@foreach ($entry as $key=>$entrys)
<td>{{ $key + 1 }}</td>
<td>{{ $entrys->bill_no }}</td>
<td>{{ $entrys->bill_date }}</td>
<td>{{ $entrys->@R_404_3996@_name }}</td>
<td>{{ $entrys->total_bill_amount }}</td>
</tbody>
@endforeach
</table>
解决方法
我认为您忘了实际联系外交关系了。
您将需要致电：$entry->purchases or $entry->purchases()->get()以获得供应商的采购集合，然后可以对其进行迭代。
<tbody>
@foreach ($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>{{ $entrys->total_bill_amount }}</td>
@endforeach
</tbody>
在您的控制器中：
public function purchaseentrylists($suppliers_master_id)
{
$entry = Supplier::where('delete_status','NOT_DELETED')
->findOrFail($suppliers_master_id);
return view('purchase.purchase-entry-list',compact('entry'));
}
