The state, the whole state and nothing but the state!
StateGate is built on the belief that ActiveRecord is already great at managing state via validations. We provide the 'gate' to ensure valid transitions, without the overhead of event DSLs and complex guard logic.
| Feature | Description |
|---|---|
| Strict States | only defined states can be set |
| Strict Transitions | only defined transitions are allowed |
| No Guarding | ActiveRecord Validations are better than guard clauses |
| No Eventing | simply change state within normal model methods |
| Fast Fail | exceptions are raised before accessing the DB or triggering any callbacks |
| No Ambiguous Result | state changes succeed, or raise an exception - no need to check the response |
| Easy Testing | built-in matchers for RSpec & Minitest make testing much easier |
| Simple to Implement | with a simple DSL, StateGate is intuitive and easy to use |
- Ruby 2.6+
- ActiveRecord 5.0+
