How to call EntityManager in a controller which is defined as a service?

Question

symfony

In a regular service, I passed the @doctrine.orm.entity_manager argument to the constructor and everything worked.
Now it took some methods in the controller to reuse, and I'm doing something wrong.
The documentation symfony.com/doc/current/cookbook/controller/servic... says
"Simply inject doctrine instead of fetching it from the container" on this. And there is no example.
How to do it right?

Answer 1

Now it took some methods in the controller to reuse

Congratulations, you are on your way to application level services and thin controllers.
instead of making controllers as services - just make services and there will be no problems.
And there are examples there: symfony.com/doc/current/book/service_container.html - read it.

Answer 2

Read what Sergei Protko suggested to you .

services:
    app.super_puper_controller:
        class: AppBundle\Controller\BlackMagicController
        calls:
            - [setContainer, ["@services_container"]]
            - [setOtherMethod, ["@router", "%my_parameter%"]]

As a result, when you initialize your controller, Symfony will go through the list of calls and call each method with parameters.
(PSY. It is better to explicitly pass arguments to the service. That is, as you did with regular services)
