Semantical Error in symfony2 while fetching the data - symfony

Question

I am trying to write a web service to fetch the category list and all the business under that category in an nested array fashion.
I am getting an Semantical Error saying :
{
code: 500
message: "[Semantical Error] line 0, col 14 near 'StreetBumbApiBundle:Buss_owner': Error: Class 'StreetBumb\ApiBundle\Entity\Buss_owner' is not defined."
}
I already defined the entity in the controller, i dont know why it is showing this error.
This is how my controller's function looks like:
public function getCategoryAction(){
$em = $this->getDoctrine()->getEntityManager();
$pro = $em->getRepository('StreetBumbApiBundle:Category')
->getBusinessByCategory();
//return $pro;
$i = 0;
foreach($pro as $p)
{
$data['category'][$i]['id'] = $p->getId();
$data['category'][$i]['Name'] = $p->getCatName();
//$result[$i] = $p->getId();
$catId = $p->getId();
$business = $em->createQuery('SELECT b FROM StreetBumbApiBundle:Buss_owner b WHERE b.catId = :catId')->setParameter('catId', $catId);
$result = $business->getResult();
foreach($result as $r)
{
$data['business'][$i]['id'][] = $r->getId();
}
$i++;
}
return $data;
}
Please guide if anyone have idea.. Thanx

Answer 1

I believe the problem is the underscore in the entity name.
Doctrine's naming convention is to use CamelCase which it then converts to underscores in the database. Due to this behind the scenes magic, underscores can cause problems in entity names.
Try changing the entity class name to BussOwner and calling this in the controller. If you can't change the table name you can handle this by modifying the entity annotation to:
#ORM\Table(name="buss_owner")
