I cannot get value from an object in blade template Laravel 4
提问by user2957058
I have a loop foreach in a blade template where i print data from a specific model, the problem is I am not able of getting the value of "$pedido->proveedor()->first()->name" in the code giveing me this error "ErrorException (E_UNKNOWN) Trying to get property of non-object (View: C:..":
我在刀片模板中有一个循环 foreach，我在其中打印来自特定模型的数据，问题是我无法在代码中获取“$pedido->proveedor()->first()->name”的值给我这个错误“ErrorException (E_UNKNOWN) Trying to get property of non-object (View: C:...”:
@foreach($pedidos as $pedido)
<tr>
<td>
{{ $pedido->id }}
</td>
<td>
{{ $pedido->proveedor()->first()->name }}
</td>
<td>
{{ date('d/m/Y', $pedido->fecha) }}
</td>
<td>
<a onclick="return confirm('deseas borar este registro?')" class="btn btn-danger btn-xs fullButton">Borrar</a>
</td>
</tr>
@endforeach
The weird thing here is when I code this "$pedido->proveedor()->first()" in side the loop of the template I get an object like this:
这里奇怪的事情是当我在模板的循环旁边编码这个“$pedido->proveedor()->first()”时，我得到一个像这样的对象：
{"name":"nombre","domicilio":"domicilio","cp":"46006","poblacion":"poblacion","ciudad":"ciudad","pais":"pais"}
but coding this "$pedido->proveedor()->first()->name" I get the error:
但是编码这个“$pedido->proveedor()->first()->name”我得到错误：
the data is sent from a controller:
数据从控制器发送：
public function listPedidos()
{
$pedidos = Pedido::all();
// this next pice of code shows me i can get the name as spected but only from php
// foreach($pedidos as $pedido){
// ddd($pedido->proveedor()->first()->name);exit;
// }
return View::make('pedidos/pedidos-list')->with('pedidos', $pedidos);
}
Another weirder thing is that I have the same code with different model and it is working.
另一件奇怪的事情是我有不同模型的相同代码并且它正在工作。
Thanks in advance for any help. ;)
在此先感谢您的帮助。;)

Problem solved:
问题解决了：
the previos answer was ok. I can use:
之前的回答没问题。我可以用：
{{ $pedido->proveedor()->first()->name }}
or
或者
{{ $pedido->proveedor->name }}
but because in one of the way of the loop there was not content to refer to i.e($pedido->proveedor didn't exixt) I use this:
但是因为在循环的一种方式中没有内容引用 ie($pedido->proveedor did not exixt) 我使用这个：
{{ isset($pedido->Proveedor->name )?$pedido->Proveedor->name :''; }}
