trying CloudCode out for the first time and loving it.
I am writing an iOS app that passes phone numbers to CloudCode to see if a phone number already has the app.
The problem is its firing the success block before the queries finish. I am guessing I need to know how many queries there are and work out if on the last one? I also seen this .then function?
Parse.Cloud.define("processNumbers", function(request, response) {
Parse.Cloud.useMasterKey();
var phoneNumbers = request.params.phoneNumbers;
phoneNumbers.forEach(function(entry) {
var query = new Parse.Query(Parse.User);
//query.equalTo("username", entry);
query.find({
success: function(results) {
console.log("has app");
},
error: function() {
console.log("not found");
}
});
console.log(entry);
});
response.success(phoneNumbers);
});
You could do use promise to perform task in series or parallel.
ref. Promises in Parallel, Promises in Series
The following is a parallel version which use Parse.Promise.when. The promise when will be resolved when all of its input promises is resolved.
Parse.Cloud.define("processNumbers", function(request, response) {
Parse.Cloud.useMasterKey();
var phoneNumbers = request.params.phoneNumbers;
var promises = [];
phoneNumbers.forEach(function(entry) {
var query = new Parse.Query(Parse.User);
//query.equalTo("username", entry);
promise.push(
query.find().then(function(results) {
console.log("has app");
}, function() {
console.log("not found");
});
)
console.log(entry);
});
return Parse.Promise
.when(promises)
.then(function() {
response.success(phoneNumbers);
});
response.success(phoneNumbers);
});
