How to exclude params from XML rendered in Grails ?

Question

Hi, I have a class :

class Category {
  String name
  SortedSet items
  static hasMany = [items:Item]
}

Inside the controller, I render category as XML (converters) :

   def getCategory = {
     render Category.read(1) as XML
   }

But I want exclude items from the rendering.

How can I do ?

Thanks

You need to create a second domain class sort of like a view and configure the mapping so it has the same table as the Category class

You can simply return a Map with only the properties you want to include:

def getCategory = {
    def category = Category.read(1)
    render [ id: category.id, name: category.name ] as XML
}
