Exclude 'id' from being retrieved from query in Grails

I have to display a list of items with their details. The controller looks like this

def showItems() {
    def items = Item.list(offset:0, max:10, sort:"updatedOn", order:"desc")
    render view : "show", model : [items : items]
}

This works perfectly fine but the problem is that the 'id' of the items is also being sent to the gsp which I don't want. How can I send all the item details from the controller to the gsp except the 'id'.

Solution

  • I don't know why you care about the ID being sent to the view, but, you can do something like:

    Item.list().collect { [prop1: it[prop1], ...] }

    to send only the properties you want.

    Another option: 

    Item.list().collect { it.subMap('key1', 'key2') }

    And even more Groovy:

    Item.list().collect{ 
    def keys = it.keySet()
    keys.remove('id')
    it.subMap( keys ) 
}​​
