How to return an array of ParseObject from CloudCode call - unity3d

Question

There is a parse CloudCode function created as such:
Parse.Cloud.define("getCurrentEvents", function(request, response) {
var TimedEvent = Parse.Object.extend("TimedEvent");
var query = new Parse.Query(TimedEvent);
query.greaterThan("expiresOn", new Date());
query.find({
success: function(results) {
response.success(results);
},
error: function(error) {
response.error("There was an error while looking for TimedEvents");
}
});
});
It returns an array of TimedEvent, as shown in the curl test here:
{"result":[{"expiresOn":{"__type":"Date","iso":"2014-07-31T22:31:00.000Z"},"playMode":"Normal","tableId":"Carnival","objectId":"J1LSO3EnKi","createdAt":"2014-07-28T21:48:22.983Z","updatedAt":"2014-07-28T22:32:14.304Z","__type":"Object","className":"TimedEvent"}]}
When trying to access it from Unity SDK however, I get a "cannot convert to destination type" exception with the following line:
System.Threading.Tasks.Task<Parse.ParseObject[]> task =
Parse.ParseCloud.CallFunctionAsync<Parse.ParseObject[]> ("getCurrentEvents", parameters);
I also tried
System.Threading.Tasks.Task<IEnumerable<Parse.ParseObject>> task =
Parse.ParseCloud.CallFunctionAsync<IEnumerable<Parse.ParseObject[]>> ("getCurrentEvents", parameters);
with the same (lack of) results. What kind of signature is the SDK expecting?

Answer 1

Have you tried something like this (without IEnumerable?):
Threading.Tasks.Task<Parse.ParseObject> task = Parse.ParseCloud.CallFunctionAsync<Parse.ParseObject>("getCurrentEvents", parameters);
But better yet, you could extend ParseObject to create your own TimedEvent class in Unity, like this:
[ParseClassName("TimeEvent")]
public class TimeEvent : ParseObject
{
[ParseFieldName("expiresOn")]
public DateTime expiresOn
{
get { return GetProperty<DateTime>("expiresOn"); }
set { SetProperty(value, "expiresOn"); }
}
[ParseFieldName("playMode")]
public string playMode
{
get { return GetProperty<string>("playMode"); }
set { SetProperty(value, "playMode"); }
}
[ParseFieldName("tableId")]
public string tableId
{
get { return GetProperty<string>("tableId"); }
set { SetProperty(value, "tableId"); }
}
// any other fields you want to access
}
Then you can query your data like this:
IEnumerator getTimedEvents(Dictionary<string, object> parameters)
{
var cloudTask = Parse.ParseCloud.CallFunctionAsync<TimeEvent>("getCurrentEvents", parameters);
while (!cloudTask.IsCompleted)
yield return null;
if (cloudTask.IsCanceled || cloudTask.IsFaulted)
{
// handle error
}
else
{
TimeEvent t = cloudTask.Result;
// do stuff with t
}
}
P.S. Don't forget to register your Parse class somewhere (I usually do it in the Awake() of an early GameObject). In your case, you would do it like this:
Parse.ParseObject.RegisterSubclass<TimedEvent>();
