How to fix "No signature of method: java.util.ArrayList.delete()" to delete a object?

Question

I'm new in grails and I'm trying to delete all the objects (ArrayList) that I'm getting.

This is the method to get the data, that is working:

def authRequest = User.findAllByExpiresLessThan(currentDate)

And this is that I'm trying to do:

if(authRequest){
    authRequest.delete()
}

This is the error:

Caused by: groovy.lang.MissingMethodException: No signature of method: java.util.ArrayList.delete() is applicable for argument types: () values: []
Possible solutions: sleep(long), sleep(long, groovy.lang.Closure), clear(), clear(), clear(), clone()

Thanks in advance.

authRequest.delete() would work if it was only 1 object.

When you use findAllBy instead of findBy, it will return an array of objects, instead of just one. In that case you can use "Spread" operator (*.) to delete them all:

authRequest*.delete()
