Form & Validation
DocumentType
This bundle provides a DocumentType to be used with the Symfony's Form
component. As DocumentType extends the EntityType provided by Symfony's
Doctrine bridge you can use all options available for the ORM users. The only
difference is that DocumentType expects the DocumentManager name or
instance passed with the document_manager option instead of em.
Unique constraint
This bundle provides a Unique constraint, which extends the UniqueEntity
constraint provided by Symfony's Doctrine bridge. This constraint allows you to
validate the uniqueness of an document field against the database.
The Unique constraint shares the same options as UniqueEntity, which
means that the em option should be used if you wish to specify the document
manager explicitly instead of having it be inferred from the document class.
