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.

ActiveRecord: Adding Boolean methods for DateTime columns
Might this be better handled with a state machine with active record integration?

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:
