How do a ProductController without database error 42S22 - cakephp

Question

I do an app that show some products with price for register people.
When create the product page show me "Database Error"
"Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Product.utype' in 'where clause'"
My ProductsController is like this:
class ProductsController extends AppController {
public function index() {
$this->Product->recursive = 0;
$products = $this->Product->find('all');
$this->set('products', $Product);
}
/**
* view method
*
* #throws NotFoundException
* #param string $id
* #return void
*/
public function view($id = null) {
$this->Product->id = $id;
if (!$this->Product->exists()) {
throw new NotFoundException(__('Invalid Product'));
}
$this->set('products', $this->Product->read(null, $id));
}
}
And the Model Product.php is like this:
class Product extends AppModel {
public $primaryKey = 'id_prod';
/**
* belongsTo associations
*
* #var array
*/
public $belongsTo = array(
'Occurrence' => array(
'className' => 'Occurrence',
'foreignKey' => 'occurrence_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
}
Can help me, please?
Thank you.

Per the very explicit error:
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column
'Product.utype' in 'where clause'"
Your code is looking for the colum 'utype' in the products table (which apparently doesn't exist). If you're not sure where your code is telling it to do that, just do a project-wide search for "utype" and update it to the correct field name.
