I've got a grails domain class I have to persist in Redis, something like this:
class A {
String one
Integer two
B three
E four
mapWith = "redis"
}
class B {
String name
}
enum E {
VALUE1, VALUE2
}
When I persist an instance of class A with the GORM .save() method, Redis saves it correctly except for the enum field "four".
As you can see the fact is known and reported here: http://jira.grails.org/browse/GPREDIS-3
Is there a good workaround to save Enum or something similar? We're thinking about an array of String objects, what do you think?
I've got this mostly implemented but it doesn't work for Gemfire and I'm waiting until it's fixed for all the supported nosql providers before pushing the fix. As a workaround you can use the inList
constraint with a combination of a persistent String
property and a non-persistent get/set pair with the name of your current property, eg
class A {
String one
Integer two
B three
String fourString
void setFour(E e) {
fourString = e?.name()
}
E getFour() {
fourString ? E.valueOf(fourString) : null
}
static constraints = {
fourString inList: E.values()*.name()
}
static transients = ['fourString']
static mapWith = "redis"
}
