When the following code is executed, I get "Error: 141 success/error was not called", but I clearly return a success if a "round" is properly retrieved from a user's answer history.
Parse.Cloud.define("analyzeRound", function(request, response) {
var x = [];
var user = request.user;
user.get("answerHistory").get("round", {
success: function(educationRound) {
for (var i = 0; i < educationRound.length; i++) {
x.push(0);
}
response.success("success");
},
error: function(error) {
response.error("failed");
}
});
});
Any help would be much appreciated!
This ended up giving me what I was looking for, thanks Mo Nazemi!
Parse.Cloud.define("analyzeRound", function(request, response) {
var x = [];
var user = request.user;
var answerHistory = user.get("answerHistory");
answerHistory.fetch({
success: function(answerHistory) {
var round = answerHistory.get("round");
for (var i = 0; i < round.length; i++) {
x.push(0);
}
response.success("success");
},
error: function(error) {
response.error("failed");
}
});
});

I'm trying to call multiple ajax in my page using $q. after all the response am storing in one array. but it seems not working correctly-
My controller-
used for loop to go over multiple pages in API and get the json.
$scope.items = [];
for (var i = 1; i < 10; i++) {
var apiURL = "https://swapi.co/api/planets?page =" + i;
searchData(apiURL).then(function(response) {
$scope.items.push(response[0].data.results);
});
}
$scope.showDetail = function(data) {
$scope.items = data.results;
$scope.items.sort(function(a, b) {
return a.population.localeCompare(b.population);
});
}
$scope.showDetail($scope.items);
$scope.highlighFont = function() {
}
My Factory-
var app = angular.module('starApp');
app.factory('searchData', function($q, $http) {
return function(apiUrl) {
var promises = [];
var deffered = $q.defer();
$http({
method : 'GET',
url : apiUrl
}).then(function(data) {
deffered.resolve(data);
}, function(error) {
deffered.reject();
})
promises.push(deffered.promise);
return $q.all(promises);
}
});
can someone correct me if am doing wrong??
You need to call $q.all() in the controller
app.factory('searchData', function($q, $http) {
return function(apiUrl) {
return $http({
method : 'GET',
url : apiUrl
});//$http returns a promise
}
});
controller:
$scope.promises = [];
for (var i = 1; i < 10; i++) {
var apiURL = "https://swapi.co/api/planets?page =" + i;
$scope.promises.push(searchData(apiURL));
}
$q.all($scope.promises).then(function(results){
console.log(results);
});
Hi i am using nightmare for scrape data from website and also course details. I occur a issue :-
err: { message: 'navigation error',
code: 0,

i have a problem.
I'm trying to build highcharts graphic.
How it works:
I'm going to my route ('ship.details'), and here i have not problems.
My problem:
subsription to (ships_snapshots_all) not working.
My publish.js:
Meteor.publish("ships_snapshots", function(user, options) {
if(!this.userId) return null;
if(this.userId) {
console.log('subsribed by ' + user);
return ships_snapshots.find({userId: user}, options);
}
});
Meteor.publish("ships_snapshots_all", function() {
return ships_snapshots.find({});
})
My subscribe.js (in lib folder):
Meteor.subscribe('ships_snapshots');
Meteor.subscribe('ships_snapshots_all');
Problem 100% in my subsription, because if i'm installing autopublish all working good. And problem in my router i think.
router.js:
Router.route('/ships/details', {
name: 'ship.details',
loadingTemplate: 'loading',
onBeforeAction: function() {
var shipId = Session.get('currentShipId');
if(!shipId) {
Router.go('user.ships');
} else {
this.next();
}
},
waitOn: function() {
if (Meteor.isClient) {
var getCompare = Meteor.user().profile.wows.compareWith;
console.log(getCompare);
var user2 = Meteor.users.findOne({"profile.wows.nickname": getCompare});
var user2Id = user2._id;
if (getCompare) {
var user2 = Meteor.users.findOne({"profile.wows.nickname": getCompare});
if (user2) {
var user2Id = user2._id;
}
}
if (getCompare) {
var handle = Meteor.subscribe('ships_snapshots', Meteor.user()._id) && Meteor.subscribe('ships_snapshots', user2Id) && Meteor.subscribe('userSearchInfo', getCompare);
Session.set('compareWith', user2);
console.log('user2 _____');
console.log(user2);
return handle
} else {
var handle = Meteor.subscribe('ships_snapshots', Meteor.user()._id) && Meteor.subscribe('ships_snapshots', user2Id);
return handle
}
}, data: function() {
if (handle.ready()) {
var shipname = this.params.shipName;
var obj = {};
var query = ships.findOne();
var shipId = Session.get('currentShipId');
var result;
_.each(Meteor.user().profile.wows.ships, function(row) {
if (row.ship_id === shipId) {
result = row;
}
});
return result;
}
}
});
I think my problem in subscripion for ship_snapshots. Something going wrong here, but i can't to resolve this problem.
What exactly do you mean by "not working"? From your code I would assume that you're always seeing all the ship snapshots.
You shouldn't have the subscribes in /lib if you have them in your router. If you have Meteor.subscribe('ships_snapshots_all'); in /lib then you should always be seeing all the ship snapshots (assuming you're not stopping that subscription anywhere).
Also your subscription to all should be:
Meteor.publish("ships_snapshots", function(user, options) {
if(this.userId) {
console.log('subsribed by ' + user);
return ships_snapshots.find({userId: user}, options);
} else this.ready();
});
You don't want to return null when there is no user, you can just mark the subscription as ready without finding any records. This is not the cause of your problem but just good practice.
Meteor.publish("ships_snapshots", function(user, options) {
if(!this.userId) return null;
if(this.userId) {
console.log('subsribed by ' + user);
return ships_snapshots.find({userId: user._id}, options);
}
});
In your publish script, is user really an id or is it a user object? I changed it to user._id. Please check that.
I am making a meteor call and getting array in return on the client side.
I want to use this array in an event inside Template but the array is not recognized outside the meteor call.
How to access this array in a Template event?
if (Meteor.isClient) {
result=[];
Meteor.call('getApiResult', function (err, result) {
if (result) {
console.log("reached meteor call")
console.log(result);
}
});
Template.dpVar.events = {
'click .addproduct' : function (err) {
for (i = 0; i < result.length; i++) {
var Temp_Name = result[i];
var Temp_Val = document.getElementById(Temp_Name).value
console.log("temp name is ", Temp_Name);
productDB.insert({ Temp_Name: Temp_Val});
console.log("temp val is ", Temp_Val);
}
}
}//Client Ends
You aren't setting result, you are overloading the name ;-)
Try this, if it doesn't work, move result = [] into the global scope.
if (Meteor.isClient) {
result = [];
Meteor.call('getApiResult', function (err, res) {
if (res) {
console.log("reached meteor call")
console.log(res);
result = res;
}
});
Template.dpVar.events = {
'click .addproduct' : function (err) {
for (i = 0; i < result.length; i++) {
var Temp_Name = result[i];
var Temp_Val = document.getElementById(Temp_Name).value
console.log("temp name is ", Temp_Name);
productDB.insert({ Temp_Name: Temp_Val});
console.log("temp val is ", Temp_Val);
}
}
}
}
getTime: function () {
host="http://www.xxxxxx.com/";
res= Meteor.bindEnvironment(function(){
var Fiber = Meteor.require('fibers');
var Future = Meteor.require('fibers/future');
var future = new Future();
request(host, function (error, response, body) {
Fiber(function(){
if (!error && response.statusCode == 200) {
$ = cheerio.load(body);
var $thumbs = $('.thumb');
for (var i = 0, l = $thumbs.length ; i < l ; i++) {
// elements
var $thumb = $($thumbs[i]);
// save info
videourl=host+$thumb.find('a').attr('href');
videothumbs = [$thumb.find('img').attr('src')];
videos=Videos.insert({title:videoTitle,thumbs:videothumbs,lastUpdated:Date.now()});
}
return videos;
}
else {
return "error";
}
}).run()
});
}) ;
return res;
}
This is a server side method and returning undefined
Without bindenvironment it is returning error to use bindenvironemnt.
Am I using it properly, can somebody tell m the modifications in my code
You need a future to return the value of inner function:
Meteor.methods({
getTime: function() {
var future = new Future();
Meteor.bindEnvironment(function() {
future.return('Some value');
});
return future.wait();
},
});
Check out this Meteorpad for an example.
If you use suggestion from #saimeunt comment, then your code could be simplified into form:
SERVER:
Meteor.methods({
getSite:function(url){
var site = HTTP.get(url);
console.log("statusCode =\n " , site.statusCode);
console.log("content.length =\n ",site.content.length);
console.log("header =\n ",site.headers);
$ = cheerio.load(content);
...
}
})
CLIENT :
Meteor.call("getSite", "http://www.google.com");
See how it works
