“Class XXX is not a valid entity or mapped super class” after moving the class in the filesystem

Question

I had an entity class in Aib\\PlatformBundle\\Entity\\User.php

I had no problems trying to create its form class through

php app/ console doc

Answer 1

Had this problem yesterday and found this thread. I created the entity with the mapping in a new bundle (e.g. MyFooBundle/Entity/User.php), did all the configuration according to the docs but got the same error from above when trying to load the app.

In the end I realized that I wasn't loading MyFooBundle in AppKernel:

new My\FooBundle\MyFooBundle()

A great way to debug this is to run this command:

app/console doctrine:mapping:info
