Question

I am wanting to sort a collection in grails by date I am currently doing the following:

def pics = Picture.findAllByChild(child, [sort: 'dateCreated', order: 'desc'])
pics.add(Post.findAllByPostedToAll(true))

Because I have added more items to the list i need to sort again by dateCreated descending
It doesn’t look like the sort class can do this.
I have tried:

pics.sort(it.dateCreated)

But this is not allowed

Answer 1

the sort method takes a closure argument, so the correct call (with implicit parens) is

pics.sort { it.dateCreated }
