Notice: Access to undefined property

Hello

I have a little problem. I don't know why show this error/notice in my view.

*Notice: Access to undefined property Institucion::name *

I am trying show the data from my view (I am working with .volt template).

<?php $institucion = institucion::find(); foreach ($institucion as $obj) { echo $obj->name; } ?>

I have a model called Institucion. My autolader and services files It's good, because I have conection with database and I can insert data on it.

Really I am begginer and I don't know what is the best practices to show data from database in a view.

public function viewAction()
{
    $institucion = institucion::find(); 
    $this->view->institucion = $institucion;
}
{% for inst in institucion %}
    {{ inst.name}}
{% endfor %}

Thanks! but It's not working.

<?php
class InstitucionController extends \Phalcon\Mvc\Controller
{
    public function ListarAction()

        $institucion = institucion::find();
        $this->view->institucion = $institucion;
    }
}
?>

Hi,

please check that

$institucion = institucion::find();

doesn't return an empty object

Hi le51,

The variable is not empty because I use a var_dump($institucion) in this View (listar.volt) and it devolve a array. I show here:

object(Phalcon\Mvc\Model\Resultset\Simple)[51]
  protected '_type' => int 0
  protected '_result' => 
    object(Phalcon\Db\Result\Pdo)[52]

          protected '_hasManyToManySingle' => null
          protected '_initialized' => 
            array (size=1)
              ...
          protected '_sources' =>

          protected '_schemas' => null
          protected '_behaviors' => null
          protected '_lastInitialized' => 
            &object(Institucion)[45]
          protected '_lastQuery' => null
          protected '_reusable' => null
          protected '_keepSnapshots' => null
          protected '_dynamicUpdate' => null

      protected '_skipped' => null
      protected '_related' => null
      protected '_snapshot' => null
  protected '_columnMap' => null
  protected '_keepSnapshots' => boolean false

So, If I detele this view (listar.volt) and print variable in the controller (InstitucionController.php) on this way, it's all right:

$institucion = institucion::find(); 

foreach ($institucion as $obj) {
    echo $obj->nombre." - ".$obj->rif."<br>";
}

But I need print variable in the view not in controller. I think which problem can be in how pass variable to the "View".

Error: Notice: Access to undefined property Institucion::name in C:\wamp\www\sistemavit\cache\volt\c%%%%wamp%%www%%sistemavit%%app%%views%%institucion%%listar.volt.php on line 23

Hi,

the way you pass variable to the view is all right. But in your view, you are using institucion.name

and the object dump show :

"institucion"."nombre"

Thanks so Much Le51 ! ! !

Ofcourse my field in database is called nombre and not name.
