How to disable returning other entities references in symfony 4?

@mac 

To disable returning other entities references when using Symfony 4, you can do the following steps:

1. Open your config/packages/doctrine.yaml file.
2. Under the doctrine key, search for the orm key. If it is not present, you can add it as follows: doctrine: orm: # ...
3. Under the orm key, add a new key called default_entity_manager if it does not exist: doctrine: orm: default_entity_manager: default # ...
4. Under the default_entity_manager key, add a new key called naming_strategy if it does not exist: doctrine: orm: default_entity_manager: default naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware # ...
5. Under the naming_strategy key, add a new key called quote_strategy if it does not exist: doctrine: orm: default_entity_manager: default naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware quote_strategy: doctrine.orm.quote_strategy.ansiquotesstrategy # ...
6. Under the quote_strategy key, add a new key called result_cache_driver with a value of null to disable caching: doctrine: orm: default_entity_manager: default naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware quote_strategy: doctrine.orm.quote_strategy.ansiquotesstrategy result_cache_driver: null # ...

Save the changes and test your application. Now, when returning entities, references to other entities should be disabled.
