Excluding some fields from JSON Serialization

[Jeffrey D. Gortatowsky]

When writing a domain object via JSON to a response in a controller, is there a way to prevent certain fields from be written? Most examples show the entire domain object being written in a controller method via render().

What I did is I used the JSON markup builder syntax to only write the fields I want written to the client. But it's ... well ... ugly I think. I hate that nagging feeling I am missing something simple... :)

The original service I am rewriting in GRAILS used the Jackson JSON library and you could annotate fields to be excluded...

Cheers

My temporary solution was to create a new object that has only the properties that will be sent to the client. And before you call the "render ()" you pass the old object as a parameter to the new and the binding of grails solve the problem.
