如何限制的Grails域属性的知名度？ [英] How to restrict visibility of domain properties in grails?

问题描述

有没有限制域名的Grails的知名度任何推荐的方式？

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

通常你你喜欢的东西拿到外用一些接口：

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)}
}

其等于

SELECT * FROM product

但默认情况下有没有不应该被填充的一个域proerties。所以，我需要的东西说。

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

所以只有一个的属性列表被包含在应答

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

推荐答案

您可以使用第二个域类有点像视图。关键是要配置映射，它具有相同的表作为产品类：

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'
   }
}

然后使用你的用户界面：

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)}
}
