I have a custom module that pulls data from several different external databases that have been defined as connections in settings.php. The current setup includes a series of controllers that have a service I have created called DataAccess injected into them. My DataAccess service has several methods that accept a
$schema parameter and based on this I use the following each time:
$connection = Database::getConnection('default', $schema);
I can then query each database as needed with this setup. I thought about injecting Database into my service from the Drupal container, but I would then need a base class like ControllerBase's create method to get that service in the first place. What would be the correct way to do this as it isn't a controller - would I use a different base class here? I am new to Drupal 8 development and trying to ensure I am following the best practices, but at the same time I don't want to overcomplicate things.
