Doctrine can't generate relations - doctrine

Question

Note: I did have done some searches before I ask.
Here is my problem:
I have two entities: One is Channel, and the other one is Plugin, a channel can have many plugins, below is the code,
Channel:
use Gedmo\Mapping\Annotation as Gedmo; // gedmo annotations
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* Mikay\MikiBundle\Entity\Channel
*
* #ORM\Table(name="channels")
* #ORM\Entity(repositoryClass="Mikay\MikiBundle\Entity\ChannelRepository")
*/
<?php
class Channel
{
/**
* #ORM\OneToMany(targetEntity="Plugin", mappedBy="channel")
*/
private $plugins;
Plugin:
use Doctrine\ORM\Mapping as ORM;
/**
* Mikay\MikiBundle\Entity\Plugin
*
* #ORM\Table(name="plugins")
* #ORM\Entity(repositoryClass="Mikay\MikiBundle\Entity\PluginRepository")
*/
<?php
class Plugin
{
/**
* #ORM\ManyToOne(targetEntity="Channel", inversedBy="plugins")
* #ORM\JoinColumn(name="channel_id", referencedColumnName="id")
*/
private $channel;
I used this command to update the database, but it never created the relation between the two tables.
php app/console doctrine:schema:update --force
So, what's the problem, could it be some config errors?
EDIT:
Note:
Don't add
#ORM\Column(name="channel_id", type="integer")
this kind annonation in Plugin entity, or it will not generate the relations between two tables, that's the cause of my problem.

Answer 1

You need to tell doctrine that these are entities.
/**
* #ORM\Entity()
*/
class Channel
{
Here is a quick way to verify that doctrine can see your entities:
php app/console doctrine:mapping:info

Answer 2

I'll repeat it here again. Don't add
#ORM\Column(name="channel_id", type="integer")
this type of annonation on the property that references other entity, in my case, is the channel property of the Plugin entity, or it will not generate the relations between two tables, that's the cause of my problem.
