Symfony2 Dependency Injection - symfony

I would like to do the following:
Inside a bundle through dependency injection add propel connection.
So every bundle can have a connection that on load will be merged all together.
Is this possible?
I have achieved this via
- { resource: #XXXX/Resources/config/databases.yml }
- { resource: #XXXXX/Resources/config/databases.yml }
but would like to do it via Dependency Injection as it will be best practice in my opinion.
Thanks a lot.

Your question is not fully clear to me. I only understood the part with loading additional configuration files in your bundles.
Bundle configurations can be loaded automatically with DIC extensions. That's what happens with the Resources/config/services.xml file.

How does Symfony know where to find the services.yml config file?

In Symfony 3.0 (and I'm sure 2.X as well), if I want to make a custom constraint validator with a dependency, I have to register that validator as a service in the dependency injection container (which is described by default in project_directory/app/config/services.yml) using a special tag ( as described here).
This means that the Validator component must know where to look for the service container. This issue also comes up for the ControllerResolver. Since controllers can be registered as services, the ControllerResolver must know where the service container is.
How do the Symfony components know where to look for the service container, and how can I configure this? I ask because I want to build a custom framework using the Symfony components, which means I'll be making my own service container, and I'd like to be able to point the Validator and the ControllerResolver to that service container.
In Symfony Standard Edition, the container is initialised by the Kernel. Have a look at the AppKernel and its parent class.
The kernel loads a configuration file in the registerContainerConfiguration() method:
public function registerContainerConfiguration(LoaderInterface $loader)
{
$loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
}
This code will load an environment specific configuration file (config_prod.yml, config_dev.yml etc). In a standard setup that file imports the main config.yml file.
The services.yml file is loaded with an import in config.yml:
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
If you're thinking of building your own framework (which is a good learning experience), you'll need to read more code of existing frameworks first. Also, it's worth to read the excellent Create your own PHP framework.
This means that the Validator component must know where to look for the service container
This is scary. I see no connection between validation and the service container. I'd think of a better design.
P.S. Everyone should write their own framework once. The next step should be deleting it.

How to register simple things entity Audit extension in symfony2

I am trying to use simple things entity audit bundle in my application, but couldnt figure out the way to get this right. Please find the steps i am trying below,
1) Installed simple things bundle into vendor directory via composer file
2) Not sure where to autoload as given in the read me file
3) Added the setting of audited entities in config.yml
simple_things_entity_audit:
audited_entities:
- AcmeDemoBundle\Entity\Vendor

But Not sure how to register them as extension in doctrine configuration. I am very new to this bundle. Any help here would be really appreciated.
Use Acme\DemoBundle\Entity\Vendor instead of AcmeDemoBundle\Entity\Vendor

Deleting not needed bundles from Symfony 2?

Is possible to delete bundles not needed in order to keep the project clean? I'm using Symfony2 with propel to build a RESTful interface. Don't need:
Twig
Doctrine2 (i prefer Propel instead)
Assetic (without Twig assetic does not make sense, correct me if i'm wrong)
Security (no need to model roles)
I can't find any how-to in order to remove uneeded bundles. Any help is much appreciated.
EDIT: monlog is the logger, not mongodb. Need it!
About deps.lock file: it can be removed after removing bundles, than issue:
php bin/vendors update
and i should be recreated. It maintains the git version id checked out, for each bundle.
Sure. Remove them from AppKernel then delete from the file system if you want. You could even edit the deps file to keep them from coming back. Twig and Assetic are independent. You could use the Assetic bundle with straight PHP.
In case anyone else runs into this issue, you can follow the instructions in the Symfony2 docs to remove the Acme Bundle: http://symfony.com/doc/2.0/cookbook/bundles/remove.html
The proccess is like this:
delete /src/Test/BlogBundle directory
change /app/config/routing.yml file to remove the bundle routes
Unregister your bundle from /app/AppKernel.php
clear cache (either by deleting cache/{$env} or console cache:clear)

Can I use variables defined in parameters.ini in validationor routing?

I was wondering if I could define some variables in parameters.ini and use them in various yml files like validation, routing, etc?
Is this possible?
For any of Symfony2's YAML files that support imports, you can use the following syntax:
imports:
- { resource: parameters.yml }
Of course, this requires a bit of upgrading since parameters.yml is currently Symfony 2.1.x and 2.0.x still uses parameters.ini.
You would be better off passing variables around using service parameters. See this section of the documentation on the service container.
The configuration of validator and routing differs in its implementation.
DependencyInjection configuration files support the imports keyword.
Routing configuration files support the resources keyword.
Validator configuration files do not support import.
Translation configuration files do not support import.

symfony2 custom_provider

I have been trying to follow this example from propel to configure a custom security provider
http://www.propelorm.org/cookbook/symfony2/the-symfony2-security-component-and-propel.html
however I always get this error
ServiceNotFoundException: The service "security.authentication.manager" has a dependency on a non-existent service "acme.secured.security.provider"
It appears not to be loading the services.xml but I cannot be sure. Has anyone else come across a similar issue? Im new to symfony2, can anyone suggest the best place to start debugging this?
So import it. In your app/config.yml:
imports:
acme_bundle:
resource: "#AcmeSecuredBundle/Resources/config/services.xml"
You can read more about importing services in the documentation.
