Use the chain provider defined from a service

Question

I use multiple user providers in my app:

security:
    providers:
        chain_provider:
            chain:
                providers: [entity, json]
        entity:
            id: myapp.entity.user_provider
        json:
            id: myapp.json.user_provider

Now I need to load a user from a service

services:
    myapp.my.service:
        class: AppBundle\Services\My
        argument: [@the.defined.chain.provider]

// AppBundle\Services\My
namespace AppBundle\Services;
class My
{
    public function loadUser($username)
    {
        return $this->userProvider->loadUserByUsername($username);
    }
}

How can I use the chain provider explicitly ?

The providers are initialised as services and you can do the same with the Chain provider:

services:
    the.defined.chain.provider:
        class: Symfony\Component\Security\Core\User\ChainUserProvider
        arguments: [ [ @myapp.entity.user_provider, @myapp.json.user_provider ] ]

Then in your security.yml file, replace your providers with:

security:
    providers:
        default: 
            id: the.defined.chain.provider

And in your services file just keep your example for myapp.my.service

So you'd be creating the user provider chain yourself as a service (which is effectively what the security bundle does with your configuration) and using it in two places.

By looking at the code of SecurityBundle, you just can use the service security.user.provider.concrete.{name}, so in your case security.user.provider.concrete.chain_provider

Interesting, will it automatically get the providers array as argument ? – Pierre de LESPINAY Jul 25 '15 at 06:36
Yes. Basicly, you got bundles, which define base services and configuration options. Then it use your configuration to configure its services/parameters in the container. Here you configure a chain provider named `chain_provider` with two providers, Symfony will know that it have to create a service `security.user.provider.concrete.chain_provider` and use your configured providers as the first argument of it. – Yassine Guedidi Jul 25 '15 at 07:56
Fine ! I'll check that too, Thanks – Pierre de LESPINAY Jul 25 '15 at 08:05
If my answer helped you, can you please validate it? – Yassine Guedidi Jul 25 '15 at 14:18
I sure will when I'll be able to check – Pierre de LESPINAY Jul 27 '15 at 08:53
