如何限制 grails 中域属性的可见性? [英] How to restrict visibility of domain properties in grails?

问题描述

是否有任何推荐的方法来限制 grails 中域的可见性?

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

通常你会做一些事情，比如获取一些供外部使用的界面:

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)}
}

等于

SELECT * FROM product

但默认情况下，不应填充域中的属性.所以我有话要说

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

因此答案中仅包含属性列表.

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

推荐答案

您可以使用类似于视图的第二个域类.诀窍是配置映射，使其与 Product 类具有相同的表:

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'
   }
}

然后在您的用户界面中使用它:

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)}
}
