Many to One Unidirectional relation in symfony2 has "No Association error" - symfony

Question

I am trying to create a many to one unidirectional relationship between two tables. dateTime and availibilityList are two entities, one list may have multiple date and time.
I added the annotations likewise in the entity dateTime but it is showing me this error:
{
code: 500
message: "[Semantical Error] line 0, col 84 near 'd WHERE d.offerAvailibilityId': Error: Class StreetBumb\ApiBundle\Entity\availibilityList has no association named dateTime"
}
I updated my schema from the terminal by using this:
sudo php app/console doctrine:schema:update --force
It says : your database is already in sync with the current entity metadata.
dateTime Entity:
<?php
namespace StreetBumb\ApiBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* dateTime
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="StreetBumb\ApiBundle\Entity\dateTimeRepository")
*/
class dateTime
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var \DateTime
*
* #ORM\Column(name="startDate", type="date")
*/
private $startDate;
/**
* #var \DateTime
*
* #ORM\Column(name="endDate", type="date")

private $endDate;
/**

private $startTime;
/**

private $endTime;
/**

private $type;
/**

private $offerAvailibilityId;
/**

public function getId()
{
return $this->id;
}
/**

public function setStartDate($startDate)
{
$this->startDate = $startDate;
return $this;

{
$this->endDate = $endDate;
return $this;
}

public function getEndDate()
{
return $this->endDate;
}
/**

public function setStartTime($startTime)
{

return $this;

public function getStartTime()
{
return $this->startTime;
}
/**

*/
public function setEndTime($endTime)
{
$this->endTime = $endTime;
return $this;
}
/**

*/
public function getEndTime()
{
return $this->endTime;
}
/**

* #return dateTime
*/
public function setType($type)
{
$this->type = $type;
return $this;
}
/**

*
* #return string
*/
public function getType()
{
return $this->type;
}
/**
* Set offerAvailibilityId
*
* #param integer $offerAvailibilityId
* #return dateTime
*/
public function setOfferAvailibilityId($offerAvailibilityId)
{
$this->offerAvailibilityId = $offerAvailibilityId;
return $this;
}
/**
* Get offerAvailibilityId
*
* #return integer
*/
public function getOfferAvailibilityId()
{
return $this->offerAvailibilityId;
}
}
The function in repository i am calling in controller.
public function findOpeningDetailById($id)
{
$qb = $this->getEntityManager()->createQueryBuilder()
->select('list')
->from('StreetBumbApiBundle:availibilityList', 'list')
->innerJoin('list.dateTime', 'd')
->where('d.offerAvailibilityId = :id')->setParameter('id', $id) //This line is showing error
->getQuery()->getResult();
return $qb;
}
Is there any problem in my join query or the relation i made(Many to one) is incorrect?
Please guide..
Thank you
