I'm experiencing a problem trying to fit my Entities in the Sonata Admin Bundle. I have something like 5 entities, which are finely listed and viewed in the bundle, but I cannot edit or create a new entry.
When I try to edit or create, I get a ReflectionException error:
Class does not exist
I tried in order to solve that problem to operate on namespaces (moving controller in the same namespace that Admin files, or so) or to tweak the Admin Controller in order to tell it about my entities ("->add('individual', 'entity', array('class' => 'Platform\ProjectBundle\Entity\Individual'))" instead of ->add('individual')).
My entity is named Biosample. Here is the Entity file:
<?php

Well, the reason for this error was a bad copy/paste from the tutorial.
In the Admin Class, the function configureFormFields contained a field "Description" badly described.
->with('Description')
->add('description', 'sonata_type_model', array('multiple' => false))
->end()
I had to replace it to:
->with('Description')
->add('description')
->end()
I discovered that automatic Admin Class skeleton generation was a function of Sonata Admin Bundle. In order to automatically generate, execute:
php app/console sonata:admin:generate
Then enter the full path to your entity, in this example:
Platform\ProjectBundle\Entity\Biosample
The admin bundle will parse your entity and :
I guess this should be the prefered method when one is starting with sonata admin bundle.
