    <p>so, i have two entities: <code>Genre</code> and <code>Game</code></p> <p><strong>Genre.php</strong></p> <pre><code>&lt;?php namespace Acme\Bundle\DemoBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Doctrine\Common\Collections\ArrayCollection; /** * Genre * * @ORM\Table(name="genre") * @ORM\Entity */ class Genre { /** * @var integer * * @ORM\Column(name="id", type="integer", nullable=false) * @ORM\Id * @ORM\GeneratedValue(strategy="IDENTITY") */ protected $id; /** * @var string * * @ORM\Column(name="name", type="string", length=64, nullable=false) */ protected $name; /** * @var string * * @ORM\Column(name="display", type="string", length=64, nullable=false) */ protected $display; /** * @var string * * @ORM\Column(name="description", type="text", nullable=false) */ protected $description; /** * @var ArrayCollection|Game[] * * @ORM\ManyToMany(targetEntity="Game", inversedBy="genres", cascade={"persist"}) */ protected $games; // ... Irrelevant Constructor and following getters/setters } </code></pre> <p><strong>Game.php</strong></p> <pre><code>&lt;?php namespace Acme\Bundle\DemoBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Doctrine\Common\Collections\ArrayCollection; /** * Game * * @ORM\Table(name="game") * @ORM\Entity */ class Game { /** * @var integer * * @ORM\Column(name="id", type="integer", nullable=false) * @ORM\Id * @ORM\GeneratedValue(strategy="IDENTITY") */ protected $id; /** * @var string * * @ORM\Column(name="name", type="string", length=256, nullable=false) */ protected $name; /** * @var string * * @ORM\Column(name="display", type="string", length=256, nullable=false) */ protected $display; /** * @var string * * @ORM\Column(name="description", type="text", nullable=false) */ protected $description; /** * @var ArrayCollection|Genre[] * * @ORM\ManyToMany(targetEntity="Genre", inversedBy="games", cascade={"persist"}) * @ORM\JoinTable(name="genre_game", * joinColumns={@ORM\JoinColumn(name="genre_id", referencedColumnName="id")}, * inverseJoinColumns={@ORM\JoinColumn(name="game_id", referencedColumnName="id")} * ) */ protected $genres; /** * @var ArrayCollection|Platform[] * * @ORM\ManyToMany(targetEntity="Platform", inversedBy="games", cascade={"persist"}) * @ORM\JoinTable(name="platform_game", * joinColumns={@ORM\JoinColumn(name="platform_id", referencedColumnName="id")}, * inverseJoinColumns={@ORM\JoinColumn(name="game_id", referencedColumnName="id")} * ) */ protected $platforms; /** * @var Image[] * * @ORM\OneToMany(targetEntity="Image",mappedBy="game_id", cascade={"persist"}) */ protected $images; } </code></pre> <p>When i run <code>php app/console doctrine:schema:create</code> or <code>update</code>, it creates all of the needed join tables I specified above, but it also creates <strong><code>genre_genre</code></strong></p> <p>This table is always empty, and doesnt seem to do anything, and prevents me from running <code>php app/console doctrine:schema:update</code>'s later, and its trying to add an index to it that already exists</p> <p>Anyone see what I'm doing wrong?</p>

    1. COGame->genres and Genre-game are inversed by each other, which is invalid - one needs to be owning. I believe there is a doctine:schema:validate command you would find useful

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
