Doctrine 2 ManyToOne image annotations

TwitterTweets object:

/**
 * MyBundle\CoreBundle\Entity\TwitterTweets
 *
 * @ORM\Table(name="twitter_tweets")
 * @ORM\Entity
 */
class TwitterTweets
{
    /**
     * @var TwitterUsers
     *
     * @ORM\ManyToOne(targetEntity="TwitterUsers", inversedBy="tweets")
     * @ORM\JoinTable(name="twitter_tweets",
     *   joinColumns={
     *     @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
{
    /**
     * @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 :)

It Many-To-Many

is actually defined through @JoinTable

. To determine Many-To-One

, you should simply:



/**
     * @var TwitterUsers
     *
     * @ORM\ManyToOne(targetEntity="TwitterUsers", inversedBy="tweets")
     * @ORM\JoinColumn(name="twitter_user_id", referencedColumnName="twitter_id")
     */
