I am using sonataNofificationBundle, they have provided four backends. I have the custom requirement so want to add one more backend. They have backend configurations in
DependencyInjection/configuration.php,
DependencyInjection/SonataNotificationExtension.php,
Resources/Config/backend.xml.
Instead of making changes in sonataNotificationBundle files, I want to create bundle which override these files to create one more backend.
Does Symfony2 allow to override DependencyInjection configuration files ? Is there any way to achieve the same goal ?
Maybe you want to take a quick glance at the official doc about overriding bundles configurations?
