Validate state transition easily without any gem
You can use state machine gems, such as aasm to write validation. But the gem introduces new DSL to write state transition. It's too much just for validation.

Why Developers Never Use State Machines (2011)
As a regular user of the state_machine Ruby gem, I wouldn't recommend it. If you don't believe me, just check out the "Class definition" section of the usage examples: https://github.com/state-machines/state_machines#usage
The problems are obvious. It's built on magic and indirection. This leads to difficult to debug state machine problems. For anything beyond simple state machines you quickly lose any idea of what your object is doing.

Ruby 3 Released
Here's an example of how it can happen - look at the code examples in https://github.com/state-machines/state_machines - almost everything you are coding is in the DSL of that library if you are using it:
