Hi folks 🙂 I'd like to develop a scaffolding feature for my framework but I cannot find a way to execute a query having the Domain artefect, something I got like this:

Copy code

def domain = grailsApplication.getArtefact('Domain', 'MyDomainClass')

Is there a way to do it? Am I in the wrong direction?

Hi, I might be missing some context here, but this seems to work:

Copy code

class Book {
    String title
}

Copy code

def domainClass = grailsApplication.getArtefact('Domain', 'Book').clazz
domainClass.withTransaction {
    def book = domainClass.declaredConstructors[0].newInstance([title: 'Grails in Action'])
    book.save()
    book.list().each {
        println it.title
    }
}

Okay I've tried it but I need to call

list()

without creating a new instance of a Book. I still havent find a way, any suggestion?

Copy code

def domainClass = grailsApplication.getArtefact('Domain', 'Book').clazz
domainClass.withTransaction {
    domainClass.list().each {
        println it.id
    }
}

Thank you @mattias_reichel but I must be missing something, your code is not working for me, there is no

list()

method on the class. I'm on Grails 6

You cannot use

@CompileStatic

. Have you tried without that?
