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. .. _`EntityType`: https://symfony.com/doc/current/reference/forms/types/entity.html .. _`UniqueEntity`: https://symfony.com/doc/current/reference/constraints/UniqueEntity.html
