Symfony 4 and Sonata News Bundle Error during Intallation

I got the following error during installing SonataNewsBundle.

Unable to register extension "Sonata\FormatterBundle\Extension\ControlFlowExtension" as it is already registered in . (which is being imported from "/home/yoesoff/Documents/projects/oblog/config/routes/sonata_admin.yaml"). Make sure there is a loader supporting the "sonata_admin" type.

Error

And following Error 

The target-entity App\Entity\SonataMediaMedia cannot be found in 'App\Entity\SonataClassificationCollection#media'.

enter image description here

I just followed the official documentation from here.

Anybody can help regarding it?

Solution

  • There's a step missing in the documentation - looks like we manually need to add an extra package that creates the missing classes:

    composer require sonata-project/media-orm-pack

    Note that if you are using sonata-project/classification-bundle, you need to fix annotations for App\Entity\SonataMediaMedia::$category like so:

    /**
 * ORM\ManyToOne(
 *     targetEntity="App\Entity\SonataClassificationCategory",
 *     cascade={"persist"}
 * )
 * ORM\JoinColumn(name="category_id", referencedColumnName="id", onDelete="SET NULL")
 *
 * @var SonataClassificationCategory
 */
protected $category;

    If it helps, as far as I understand we should be skipping the sonata:easy-extends:generate steps when using Symfony 4 / Flex.

    The Flex recipes should be creating classes in our App\Entity namespace.

    If they do not it will be something along the lines of the above where things need added manually.
