Question

I am testing out a controller and simply want to retrieve the JSON. However, I’m noticing that the controller returns data but it does not return the JSON properly with the key/value pairs. It literally only returns the data. I notice however, that if I use Incident.getAll(), it returns the JSON properly. For example, it will return [INCIDENTID: “Value”] as opposed to using executreQuery which just returns the data.

My code:

def incident = Incident.executeQuery("select a.INCIDENTID from Incident a")
render incident as JSON

Answer 1

The result from executeQuery is a list of the properties you specified, not actual domain objects. For example:

TestDomain.executeQuery("select t.id from TestDomain") as JSON
===> [1, 2, 3]

If you want domain objects, you can use findAll instead. Try something like this:

TestDomain.findAll("from TestDomain") as JSON
===>[{"class":"TestDomain","id":1,"name":"one"},
  {"class":"TestDomain","id":2,"name":"two"},
  {"class":"TestDomain","id":3,"name":"three"}]
