Queries with limit does not return any cursor

[leocabral]

If we send a query param with limit (/endpoint/?q={"limit": 3}) it does not return any cursor in the results json... it would be nice to have it :wink:

Today the solution is to work with an Action and the Java API.

Planning to work on this issue soon..

Fix 0402b99

Currently the solution is this:

• Pass an empty string 'cursor' inside the q json to the server, so that a cursor is returned (I made it this way for backwards compatibility);
• If that is done, the return structure will change: instead of an array of results, it will be an object, with the results array as a member (results) and a second element, cursor, that is the cursor for the next query;
• For the following queries, pass the cursor string recieved in the cursor element of the q object.

Something like this:

String cursor = "";
for (int i = 0; i < total; i += limit) {
    String json = get("/parents", params("q", "{ limit: " + limit + ", cursor: '" + cursor + "' }"));
    process(asJsonObject(json).get("results")); // process
    cursor = asJsonObject(json).get("cursor").getAsString(); // next cursor
}

If @feroult, @leocabral or @matheusmr13 see a better way to do it without breaking the previous API, please care to comment :)

@luanpotter, I think this is a pretty good solution, not only for back compatibility. :dart:
