In my app I am generating n
number of classes. They all have the same skeleton and serve a similar purpose. They also share dependencies.
Instead of adding n
entries in services.xml
like so:
<service id="acme.security.first_voter" class="Acme\SecurityBundle\Security\Authorization\Voter\FirstVoter" public="false">
<tag name="security.voter" />
<argument type="service" id="logger" />
</service>
<service id="acme.security.second_voter" class="Acme\SecurityBundle\Security\Authorization\Voter\SecondVoter" public="false">
<tag name="security.voter" />
<argument type="service" id="logger" />
</service>
I'd like to simply add one entry like this:
<service id="acme.security.base_voter" class="Acme\SecurityBundle\Security\Authorization\Voter\BaseVoter" public="false">
<tag name="security.voter" />
<argument type="service" id="logger" />
</service>
and in each Voter simply add
use Acme\SecurityBundle\Security\Authorization\Voter\BaseVoter;
class FirstVoter extends BaseVoter
But that does not work.
I've seen Managing Common Dependencies with Parent Services, but it does not solve my issue, becouse it requires I add a
<service id="acme.security.first_voter" class="Acme\SecurityBundle\Security\Authorization\Voter\FirstVoter" parent="base_voter"/>
<service id="acme.security.second_voter" class="Acme\SecurityBundle\Security\Authorization\Voter\SecondVoter" parent="base_voter"/>
for each voter... but thats exacly what I'm trying to avoid, becouse n
can be 5 or.. 500.
I've read some old Richard Miller blog posts about injecting a dependency into an interface, and all classes implementing that interface would "inherit injected dependencies" (also be injected that service). Thats exacly what I need! Unfortunately, this has been dropped for some reason and it does not work for Symfony2.3.
Is there any solution to my problem?
