EnableAutoMapping

This constraint allows to enable Doctrine's auto mapping on a class or a property. Automapping allows to determine validation rules based on Doctrine's annotations and attributes. You may use this constraint when automapping is globally disabled, but you still want to enable this feature for a class or a property specifically.

Applies to	property or method
Class	EnableAutoMapping

Basic Usage

In the following example, the EnableAutoMapping constraint will tell the validator to gather constraints from Doctrine's metadata:

Options

The groups option is not available for this constraint.

`payload`

type: mixed default: null

This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
