Please avoid 'rand' if possible. It does not guarantee uniqueness which means that there is a risk of collisions. Possible alternatives:
|
|
|
|
|
- If you need unique values, consider using 'SecureRandom.uuid'.
|
|
|
|
|
- To randomly select a value from a list, use [].sample.
|
|
|
|
|
- To generate random test data that does not need to be unique, you can use 'Faker::*'.
