+You can have different validation for each [operation](operations.md) related to your resource.

+With this configuration, there are three validation groups:
+
+`Default` contains the constraints that belong to no other group.
+
+`postValidation` contains the constraints on the name and author (length from 2 to 50) fields only.
+
+`putValidation` contains the constraints on the author (length from 2 to 70) field only.
