Definition Validation ===================== By default, CRUDlex validates the yml file and throws an exception if anything is wrong. ---------------------- Turning off Validation ---------------------- This costs a bit of performance, so you might want to turn it off in your production environment as it should be sure at this point that the file is valid: .. code-block:: php $app['crud.validateentitydefinition'] = $app['debug']; ------------------------------- Implementing a Custom Validator ------------------------------- It is possible to use your own validator by implementing the interface **CRUDlex\EntityDefinitionValidatorInterface** and handing it in before registering the service provider: .. code-block:: php $app['crud.entitydefinitionvalidator'] = $myCustomValidator;
