Rendering JSON in grails

Question

I use the following code to render data in JSON format.

render(contentType:\"text/json\") {
    results = array {
        db.eachRow(query) { row ->
                  


        

Answer 1

Only off by a little bit :) Just need to change

aMap.put("A", a)

to be a collection or list, rather than a map. so something like

def aList = []
aList << a

Will get you what you want!

As a sidenote, there is a JSON converter in grails that will do that string building for you. Look into it here
