copied!<p>When merging a User, you want the associated Company and Privilege to be merged as well, correct?</p> <p>This process is called cascading:</p> <p><a href="http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/working-with-associations.html#transitive-persistence-cascade-operations" rel="noreferrer">http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/working-with-associations.html#transitive-persistence-cascade-operations</a></p> <p>In your User entity put <code>cascade={"merge"}</code> in the <code>@ManyToOne</code> annotation (or another type of association-definition you are using) for <code>$company</code> and <code>$privilege</code>.</p> <p>And if you want the detach call to be cascaded too (which is recommended), put in <code>cascade={"detach", "merge"}</code>.</p> <p>p.s.: Don't put such cascades on both sides of one association, you'll create an endless loop ;)</p> <p><strong>Edit:</strong></p> <p>This piece of code:</p> <pre><code>$entity = $cacheDriver->fetch($cacheId); $em->merge($entity); // <- return $entity; </code></pre> <p>should be:</p> <pre><code>$entity = $cacheDriver->fetch($cacheId); $entity = $em->merge($entity); // <- return $entity; </code></pre> <p>The thing with <code>merge()</code> is that it leaves the entity you pass as an argument untouched, and returns a <strong>new</strong> object that represents the managed version of the entity. So you want to use the return-value, not the argument you passed.</p>
