How to restrict visibility of domain properties in grails?

问题

Is there any recommended way to restrict the visibility of a domain in grails?

Normally you you do something like to get some interface for external use:

def productList = Product.list()
withFormat {
  html {[productList:productList]}
  json { render productList as JSON }
  xml { render productList as XML }
  rss { render(feedType:"rss", productList)}
}

which is equal to

SELECT * FROM product

But by default there proerties in a domain that should not be populated. So I need something to say

SELECT id, name, foo1, foo2 FROM product

so only a list of properties is included in the answer.

You can use a second domain class sort of like a view. The trick is to configure the mapping so it has the same table as the Product class:

class ProductView {

   String name
   Foo foo1
   Foo foo2

   static mapping = {
      table 'product'
   }
}

Then use that in your UI:

def productList = ProductView.list()
withFormat {
  html {[productList:productList]}
  json { render productList as JSON }
  xml { render productList as XML }
  rss { render(feedType:"rss", productList)}
}
