How to add an entity using select 2 choices?

Question

symfony

Please tell me if it is possible to do this: when you enter a string in the field that does not correspond to any entity, an entity with that "name" was created and written to the database.

Answer 1

what is stopping you from getting this line in the controller and creating this entity yourself?
For example, we get $city = $form->get('city')->getData(); check if there is such a city and create it if not? The DataTransformer is needed to convert one display format to another; it should not be used as an entity record.

Answer 2

You can do anything with shapes in symphony. The easiest option in my opinion is to write your own DataTransformer.
