I’m working with a Grails application where I have a domain class that has a hasMany relationship with an enum. Here’s a simplified version of the code:

class Domain {
    static hasMany = [
        flags: Flags
    ]
}

enum Flags {
    VALUE, OTHER_VALUE
}

I need to write a GORM query that finds all Domain instances where the flags collection contains only the OTHER_VALUE enum value.

1. How can I correctly formulate a GORM query that returns Domain instances where the flags collection only contains the OTHER_VALUE enum?

2. Is there a specific way to handle hasMany relationships with enums in GORM that I’m missing?

Looking for something like

Domain.where {
   flags.contains(Flag.VALUE)
}.list()

however, the above isn’t okay.
