API for manage workouts from users using Ruby on Rails 6 and PostgreSql.

For synchronization with multiple devices, we can check for the last persisted workout in the device storage, and search in the API for the workouts after that time (created_at).

Get the last created_at and use this data to send it as a param like last_updated_at = last_workout.created_at.

For the correct synchronization, we can't persist in the device storage response after a record creation so we need to call the workout index URL with the last considered persisted date to receive all the records created after the last persistence.

Device 1 | Device 2 | Device 3 | Device 4 |        P is equal Persisted, Using just time for a simple example
01:00 P    01:00 P     01:00 P   01:00 P
02:00 P    02:00 P               04:00
03:00 p

Device 4 sent to API the request to persist the workout with time 04:00 then receive the return of this with the ID and not mark this as persisted. Now Device 4 calls the workout index with the last persisted date (last_updated_at = 01:00) and receive all the records after this date being able to persist the results.

Device 1 | Device 2 | Device 3 | Device 4 |
01:00 P    01:00 P     01:00 P   01:00 P
02:00 P    02:00 P               02:00 P
03:00 P                          03:00 P
                                 04:00 P

This way all the other devices can do the same and become synchronized.
