    <p>I have created an entity using the yml-syntax in my symfony bundle, in the Resources/config/doctrine folder:</p> <pre><code>Sulu\Bundle\TranslateBundle\Entity\Translation: type: entity table: tr_translations id: code: type: string column: idCodes associationKey: id catalogue: type: string column: idCatalogues associationKey: id fields: value: type: text manyToOne: code: targetEntity: Code inversedBy: tr_codes joinColumn: name: idCodes referencedColumnName: id catalogue: targetEntity: Catalogue inversedBy: tr_catalogues joinColumn: name: idCatalogues referencedColumnName: id </code></pre> <p>This part is working correctly. But when I create some objects like in the following code, I get an error message that I have to use the flush method, in order to get IDs for the foreign keys.</p> <p>This is the code snippet I am currently using:</p> <pre><code> // create a new package and catalogue for the import $package = new Package(); $package-&gt;setName($this-&gt;getName()); $catalogue = new Catalogue(); $catalogue-&gt;setLocale($this-&gt;getLocale()); $catalogue-&gt;setPackage($package); $this-&gt;em-&gt;persist($package); $this-&gt;em-&gt;persist($catalogue); // load the file, and create a new code/translation combination for every message $fileCatalogue = $loader-&gt;load($this-&gt;getFile(), $this-&gt;getLocale()); foreach ($fileCatalogue-&gt;all()['messages'] as $key =&gt; $message) { $code = new Code(); $code-&gt;setPackage($package); $code-&gt;setCode($key); $code-&gt;setBackend(true); $code-&gt;setFrontend(true); $translate = new Translation(); $translate-&gt;setCode($code); $translate-&gt;setValue($message); $translate-&gt;setCatalogue($catalogue); $this-&gt;em-&gt;persist($code); $this-&gt;em-&gt;flush(); //FIXME no flush in between, if possible $this-&gt;em-&gt;persist($translate); } // save all the changes to the database $this-&gt;em-&gt;flush(); </code></pre> <p>If I don't call the flush in the foreach loop I get the following error, which I totally understand, but isn't there a more elegant solution for this problem?</p> <blockquote> <p>Doctrine\ORM\ORMException : Entity of type Sulu\Bundle\TranslateBundle\Entity\Translation has identity through a foreign entity Sulu\Bundle\TranslateBundle\Entity\Code, however this entity has no identity itself. You have to call EntityManager#persist() on the related entity and make sure that an identifier was generated before trying to persist 'Sulu\Bundle\TranslateBundle\Entity\Translation'. In case of Post Insert ID Generation (such as MySQL Auto-Increment or PostgreSQL SERIAL) this means you have to call EntityManager#flush() between both persist operations.</p> </blockquote>

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.
