I've been testing on http calls with meteor, I used nitrous (because I had no access to my dev laptop during the weekend) and it worked fine.
But when I tried to run from my local pc it returns:
Exception in delivering result of invoking 'getMatch': TypeError:
Cannot read property 'duration' of undefined.
Any ideas of what could be the cause?
Method definition:
Dota = {};
Dota.getMatch = function() {
if (!Meteor.settings.steamToken)
throw new Meteor.Error(500, 'Enter a valid Steam Token in Meteor.settings');
var matchResponse = Meteor.http.get(
"https://api.steampowered.com/IDOTA2Match_570/GetMatchDetails/V001/?",
{
params:{
"match_id": "1305454585",
"key": Meteor.settings.steamToken
}
}
);
if (matchResponse.statusCode === 200) {
return matchResponse.data.result
}
else {
throw new Meteor.Error(500, "getMatch failed with error: "+matchResponse.statusCode);
}
}
Meteor.methods({
'getMatch': function(){
return Dota.getMatch();
}
})
Calling the method:
Meteor.call('getMatch', function(error, result){
var duration = numeral(result.duration).format('00:00:00');
Session.set('duration', duration);
var winner = Meteor.myFunctions.getWinner(result.radiant_win);
Session.set('winner', winner);
});
Template.layout.helpers({
winner: function () {
return Session.get('winner');
},
duration: function () {
return Session.get('duration');
}
});
Found a solution, I changed the location of
Meteor.methods({
'getMatch': function(){
return Dota.getMatch();
}
})
to server/server.js (I had it in packages/dota/dota.js) and now it works! Thanks #user3374348 for helping!

I dynamically create collections with this method:
createPlist: function(jid) {
try {
Plist[jid] = new Meteor.Collection(pid);
} catch(e) {
console.log("oops, I did it again");
}
Plist[jid].insert({
...,
...,
public:true,
uid:this.userId
});
}
Then I am wanting to publish these selectively, and I am attempting to do it via a method:
getPlist: function(jid,pid) {
// var future = new Future();
try {
Plist[jid] = new Meteor.Collection(pid);
} catch(e) {
console.log("oops, I did it again");
}
Meteor.publish(pid, function() {
console.log(Plist[jid].find({}));
// future["return"](Plist[jid].find({}));
return Plist[jid].find();
});
// return future.wait();
},
This returns 'undefined' to my Template helper, and returns nothing (i.e. waits forever) using Future.
Any user can log in and create a Plist collection, which can be either public or not. A user can also subscribe to any collection where public is true. The variable jid is passed to the method 'getPlist' from the template. It is stored in the user's Session.
Thanks! I hope I have explained it well enough!
And of course the template:
Template.plist.helpers({
getPlist: function() {
Pl = []
jid = Session.get('jid');
//alert(jid);
pid = "pl_"+jid;
// console.log(pid);
Meteor.call('getPlist', jid, pid, function(err,res) {
console.log(res); //returns undefined
try {
Pl[jid] = new Meteor.Collection(pid);
} catch(e) {
console.log(e);
}
Meteor.subscribe(pid);
// return Pl[jid].find({}).fetch();
});
}
While trying to upload a File to my Database, I am getting a Match Error that is preventing the File to be stored.
Here is the Basic code:
The Initialization:
UserImages = new FS.Collection("userImages", {
stores: [new FS.Store.FileSystem("userImages", {path: "~/uploads"})],
filter: {
maxSize: 1048576, //in bytes
allow: {
contentTypes: ['image/*'],
extensions: ['png', 'jpg']
},
onInvalid: function (message) {
if (Meteor.isClient) {
alert(message);
} else {
console.log(message);
}
}
}
});
if(Meteor.isServer){
UserImages.allow({
insert:function(userId, doc){
return true;
},
update:function(userId, doc, fields, modifier){
check(doc, Object);
return true;
},
remove:function(){
return true;
}
})
}
The Client Code:
Template.editProfile.events({
'change #profileUpload':function(event, template){
var files = event.target.files;
for (var i = 0, ln = files.length; i < ln; i++) {
UserImages.insert(files[i], function (err, fileObj) {
if(err){
console.log(err);
}
});
}
}
});
Strangly enough, if i run a console.log(typeof file) it gives me back an Object. But when i check the File against an Object with check(file, Object) it gives me this Error:
This is the Stack from the Server:
Exception in setTimeout callback: Error: Match error: Expected plain object

Has anyone encountered this problem or has a solution for a workaround? I've tried all kinds of workarounds also with Match.Any but than I get an error telling me that all Arguments have not been run against the check();
I checked the issues in here:
https://github.com/CollectionFS/Meteor-cfs-base-package/issues
https://github.com/CollectionFS/Meteor-CollectionFS/issues
but could not find a solution so far.
Thanks for the help!
I am using keystone#0.2.32. I would like to change the post category to a tree structure. The below code is running well except when I create a category, it goes into a deadlock:
var keystone = require('keystone'),
Types = keystone.Field.Types;
/**
* PostCategory Model
* ==================
*/
var PostCategory = new keystone.List('PostCategory', {
autokey: { from: 'name', path: 'key', unique: true }
});
PostCategory.add({
name: { type: String, required: true },
parent: { type: Types.Relationship, ref: 'PostCategory' },
parentTree: { type: Types.Relationship, ref: 'PostCategory', many: true }
});
PostCategory.relationship({ ref: 'Post', path: 'categories' });
PostCategory.scanTree = function(item, obj, done) {
if(item.parent){
PostCategory.model.find().where('_id', item.parent).exec(function(err, cats) {
if(cats.length){
obj.parentTree.push(cats[0]);
PostCategory.scanTree(cats[0], obj, done);
}
});
}else{
done();
}
}
PostCategory.schema.pre('save', true, function (next, done) { //Parallel middleware, waiting done to be call
if (this.isModified('parent')) {
this.parentTree = [];
if(this.parent != null){
this.parentTree.push(this.parent);
PostCategory.scanTree(this, this, done);
}else
process.nextTick(done);
}else
process.nextTick(done); //here is deadlock.
next();
});
PostCategory.defaultColumns = 'name, parentTree';
PostCategory.register();
Thanks so much.
As I explained on the issue you logged on Keystone here: https://github.com/keystonejs/keystone/issues/759
This appears to be a reproducible bug in mongoose that prevents middleware from resolving when:
Parallel middleware runs that executes a query, followed by
Serial middleware runs that executes a query
Changing Keystone's autokey middleware to run in parallel mode may cause bugs in other use cases, so cannot be done. The answer is to implement your parentTree middleware in serial mode instead of parallel mode.
Also, some other things I noticed:
There is a bug in your middleware, where the first parent is added to the array twice.
The scanTree method would be better implemented as a method on the schama
You can use the findById method for a simpler parent query
The schema method looks like this:
PostCategory.schema.methods.addParents = function(target, done) {
if (this.parent) {
PostCategory.model.findById(this.parent, function(err, parent) {
if (parent) {
target.parentTree.push(parent.id);
parent.addParents(target, done);
}
});
} else {
done();
}
}
And the fixed middleware looks like this:
PostCategory.schema.pre('save', function(done) {
if (this.isModified('parent')) {
this.parentTree = [];
if (this.parent != null) {
PostCategory.scanTree(this, this, done);
} else {
process.nextTick(done);
}
} else {
process.nextTick(done);
}
});
I think it's a bug of keystone.js. I have changed schemaPlugins.js 104 line
from
this.schema.pre('save', function(next) {
to
this.schema.pre('save', true, function(next, done) {
and change from line 124 to the following,
// if has a value and is unmodified or fixed, don't update it
if ((!modified || autokey.fixed) && this.get(autokey.path)) {
process.nextTick(done);
return next();
}
var newKey = utils.slug(values.join(' ')) || this.id;
if (autokey.unique) {
r = getUniqueKey(this, newKey, done);
next();
return r;
} else {
this.set(autokey.path, newKey);
process.nextTick(done);
return next();
}
It works.
I encounter an error using Meteor. I call an Method.method.
Template.WelcomeTemplate.events({
'click #btn-findgame': function(e) {
e.preventDefault();
console.log('clicked find game button');
Meteor.call('allocateGame', function(error, id) {
if (error) {
alert(error.reason);
} if (id) {
Router.go('gameRoom', {_id: id})
}
})
}
})
With my Method, I check if there is an room available, create one when the isn't otherwise join. And return the ID of this room.
Meteor.methods({
allocateGame: function () {
console.log('allocateGame method called')
var user = Meteor.user();
// find game where one player is in the room
var gameWaiting = Games.findOne({players: {$size: 1}})
if (!gameWaiting) {
console.log('no game available, create a new one');
var newGameId = Games.insert({players: [user._id], active: false, finished: false});
GameDetails.insert({gameId: newGameId, gameData: []});
return newGameId
} else {
if (_.contains(gameWaiting.players, user._id)) {
console.log('Cannot play against yourself sir')
} else {
console.log('Joining game');
Games.update({_id: gameWaiting._id}, {
$set: {active: true},
$push: {players: user._id}
});
return gameWaiting._id;
}
};
}
})
And my Router:
Router.map(function () {
this.route('welcome', {
path: '/',
controller: WelcomeController})
this.route('gameRoom', {
path: '/game/_:id'
})
});
The Error I recieve is:
Exception in delivering result of invoking 'allocateGame': TypeError: Cannot read property 'charAt' of null
at Object.IronLocation.set (http://localhost:3000/packages/iron-router.js?e9fac8016598ea034d4f30de5f0d356a9a24b6c5:1293:12)
And indeed, If I don't return an ID the Routing will continue as normal. However when I return an ID in my WelcomeTemplate an error will occur.
EDIT:
Even thought my MongoDB is updating my MiniMongo DB is empty. There must be a problem with syncing. Any idea where to look?
In the route, you set the path to be '/game/_:id', that is, a parameter with the name id. In your call to Router.go, you pass a parameter with the name _id.
Don't know if this solves your problem, but it's an error.
This kind of embarrassing taking in account how many hours I've spent on fixing this. The error was created because of an error in my routers.js
this.route('gameRoom', {
path: '/game/_:id'
})
Should be:
this.route('gameRoom', {
path: '/game/:_id'
})
Happy coding.
creating service
myApp.factory('serviceHttp', ['$http', function(http) {
http.get($scope.url).then(function(result){
serviceVariable = result;
}
return serviceVariable;
}
Controller
function appController($scope, serviceHttp){
$scope.varX = serviceHttp;
if(serviceHttp){
// decision X;
} else {
// decision Y;
}
}
view:
input(ng-if='varX') serviceHttp Exist
input(ng-if='!varX') serviceHttp noExist
The above code always shows varX not exist because app installs during http call of service. I want to use angular service to inject variables from server to make decision at time of booting the application.
Try to rewrite factory by this way that returns promise:
myApp.factory('serviceHttp', ['$http', function(http) {
var factory = {
query: function () {
var data = http.get($scope.url).then(function(result){
return result;
},
function (result) {
alert("Error: No data returned");
});
return data;
}
}
return factory;
}]);
From controller:
serviceHttp.query().then(function (result) {
$scope.varX = = result;
}
Here is Demo Fiddle
in demo we used other URL source
If i correct understand you, you should doing it like this:
var app = angular.module('YourModule', []);
app.factory("serviceHttp", function($http) {
var serviceHttp={};
serviceHttp.yourGetRequest = function(yourUrl) {
return $http.get(yourUrl);
};
return serviceHttp;
});
And for example, controller:
var Controller = function($scope,serviceHttp) {
$scope.varX='';
$scope.loading = true;
var returnArr = serviceHttp.yourGetRequest($scope.url).success(function(dataFromServer) {
$scope.loading = false;
$scope.varX = dataFromServer;
})
};
in view you can use ng-show, like this:
<div ng-show="loading" class="loading"><img src="../styles/ajax-loader-large.gif"></div>
When your application start loading, $scope.loading = true and this div shown, and when you get response from server $scope.loading became false and div doesn't show.
