Doctrine 2 ManyToOne image annotations
TwitterTweets object:

class TwitterTweets
{
/**

* @ORM\JoinTable(name="twitter_tweets",

private $twitterUser;
}
TwitterUsers object:
/**
* MyBundle\CoreBundle\Entity\TwitterUsers
*
* @ORM\Table(name="twitter_users")
* @ORM\Entity
*/
class TwitterUsers
{
/**
* @var TwitterTweets
*
* @ORM\OneToMany(targetEntity="TwitterTweets", mappedBy="twitterUser")

private $tweets;
}
twitter_tweets table:
CREATE TABLE `twitter_tweets` (
`period` int(6) unsigned NOT NULL,
`tweet_id` varchar(30) NOT NULL,
`twitter_user_id` bigint(20) unsigned NOT NULL,
`tweet` varchar(255) NOT NULL,
`url` text NOT NULL,
`retweet_count` varchar(10) NOT NULL DEFAULT '0',
`created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`period`,`tweet_id`),
KEY `period` (`period`),
KEY `tweet_id` (`tweet_id`),
KEY `twitter_user_id` (`twitter_user_id`),
KEY `created_at` (`created_at`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
twitter_users table:
CREATE TABLE `twitter_users` (
`twitter_id` bigint(20) unsigned NOT NULL,
`user` varchar(255) NOT NULL,
`username` varchar(255) NOT NULL,
`profile_image_url` text NOT NULL,
PRIMARY KEY (`twitter_id`),
KEY `user` (`user`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
I am getting this error while doing a simple SELECT:
$this->getDoctrine()->getRepository('MyBundleCoreBundle:TwitterTweets')->findOneBy(array( 'tweetId' => $data->tweet_id ))
Column not found: 1054 Unknown column 't0.twitterUser_id' in 'field list'
SELECT t0.period AS period1, t0.tweet_id AS tweet_id2, t0.tweet AS tweet3,
t0.url AS url4, t0.retweet_count AS retweet_count5, t0.created_at AS created_at6,
t0.twitterUser_id AS twitterUser_id7
FROM twitter_tweets t0 WHERE t0.tweet_id = ?
How can I solve this problem? I tried to set only @ORM \ JoinColumn (no JoinTable annotation), but I get this error:
"message": "SQLSTATE [42S02]: Base table or view not found: 1146 Table" database.twittertweets_twittertrends "does not exist"

Decided to use many-to-one unidirectional association mapping : http://docs.doctrine-project.org/projects/doctrine-orm/en/2.0.x/reference/association-mapping.html#many-to-one-unidirectional
TwitterTweets object:
/**
* MyBundle\CoreBundle\Entity\TwitterTweets
*
* @ORM\Table(name="twitter_tweets")
* @ORM\Entity
*/
class TwitterTweets
{
/**
* @var TwitterUsers
*
* @ORM\ManyToOne(targetEntity="TwitterUsers")
* @ORM\JoinColumn(name="twitter_user_id", referencedColumnName="twitter_id")
*/
private $twitterUser;
}
TwitterUsers object:
/**
* MyBundle\CoreBundle\Entity\TwitterUsers
*
* @ORM\Table(name="twitter_users")
* @ORM\Entity
*/
class TwitterUsers
{
// ... no properties needed
}
Thanks to jperovic for the help :)
