I'm in need to fetch over 1000 elements from a Class.
So I tried following advices on this topic, but something is not working correctly, and already spent the whole day to find a solution.
Parse.Cloud.define("getFollow", function(request, response) {
var following = [];
var user = request.params.user;
user.fetch().then(function(result) {
if (!result.get('following')) {
following = getFollowing({
'user': user
});
}
}).then(function() {
response.success(following);
}, function(error) {
response.error(error);
});
});
function getFollowing(request) {
var count = 0;
var skip = request.skip || 0;
var limit = 1000;
var following = request.following || [];
var Follow = Parse.Object.extend('follow');
var query = new Parse.Query(Follow);
query.limit(limit);
query.ascending('objectId');
query.skip(skip * limit);
query.equalTo('followers', request.user);
query.find().then(function(results) {
skip+= 1;
count = results.length;
/* I can't see any DEBUG, seems nothing is queried */
console.log('[DEBUG] Check <count>: ' + count);
return Parse.Promise.when(results.map(function(result) {
following.push(result.get('followed'));
}));
}).then(function() {
if(count >= limit) {
following = getFollowingUsers({
'user': request.user,
'skip': skip,
'following': following
});
}
}).then(function() {
return following;
}, function(error) {
return error;
});
}
I tried many variant of this code, trying to return the very first result of the query, rather than a collection. I also tried to remove all contraints, but even so, my query seems not to be run.
I also tried to use a Cloud.code function to make this recursively using only Parse.Cloud, but if I do that, I'm having a message Too many recursive calls into Cloud Code
What did I do wrong with this logic ?
