What do we prefer ?

The question is : when should we go for NilObject classes : from the first method to unify the way to handle this kind of things in the code base or wait until you have something a bit complex to do it ?

Given

So let's say we have a Cup model that has tray_uuid and barcode attributes. In one case we want to get a Cup that is linked to a specific barcode and return the uuid of the tray it's stored on.

Docker - Hosting

For a long time deploying web applications involved one of the following :

• package the app in a tar bar or an “evolved” tar ball (deb, rpm) and extract it on the hosts
• use your favorite configuration management system and a remote command execution to deploy the latest tag of your branch

In both cases you can use some amount of automation with Salt/Chef/Puppet/Ansible for example.

Yet I am not happy with that process. The usual steps are as follow :
