Set message for unique contraint violation in Grails

In Grails,

When an specific 'unique' constraint is violated, I want to set the message of the Exception that rises.

Is that possible?

Solution

  • The message code to use for each constraint is listed in the reference page for that constraint, e.g. http://grails.org/doc/latest/ref/Constraints/unique.html. From that it looks like the code you need is 

    com.project.ModelName.fieldName.unique=blah

    You need to replace com.project.ModelName.fileName with your appropriate value
