#Gracefully validating unique
constraints
This API requires at least Dewdrop 1.33.0.
When your database defines a UNIQUE constraint, it's important to catch violations of that constraint
in your application so that users aren't confronted with inscrutable error pages when the database
throws an exception. Dewdrop provides an easy to use API for this situation. You'll typically
use this API in the init() method of your model classes.
