Experiencing some serious problems in getting a OneToMany relationship to work. The error happens when trying to add "Children" to Beauties in Sonata Admin.
Using:
Symfony2 Doctrine Sonata Admin
Been trying to follow the guide at: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/association-mapping.html#one-to-many-bidirectional
and
http://sonata-project.org/bundles/doctrine-orm-admin/2-2/doc/reference/form_field_definition.html
Error:
"CRITICAL - Uncaught PHP Exception Doctrine\ORM\ORMInvalidArgumentException: "A new entity was found through the relationship 'Beautify\BeautiesBundle\Entity\Beauty#children' that was not configured to cascade persist operations for entity: Beautify\BeautiesBundle\Entity\Children@000000000eff91d5000000017f8ca53b. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'Beautify\BeautiesBundle\Entity\Children#__toString()' to get a clue." at /Users/gmf/symfony/vendor/doctrine/orm/lib/Doctrine/ORM/ORMInvalidArgumentException.php line 91 "
