Grails bind request parameters to enum

Question

My Grails application has a large number of enums that look like this:

public enum Rating {
    BEST(\"be\"), GOOD(\"go\"), AVERAGE(\"av\"), BAD(\"ba\"), WORST(\         


        

Answer 1

So the default Databinding binds on the Enum name and not a separately defined property of the Enum. You can either create your own PropertyEditor as you have mentioned or do a work-around similar to this:

class MyCommand {
 String ratingId
    Rating getRating() {
     return Rating.getEnumFromId(this.ratingId)
    }
    static constraints = {
     ratingId(validator:{val, obj -> Rating.getEnumFromId(val) != null })
    }
}
