Using Meteor.call inside a server router - meteor

Router.route('/sms/inbound', function () {
if (something) {
Meteor.call("addUser", {
name: "hello",
age: 20
})
}
}, {where: 'server'});
I want to do something like above. However, since Meteor.call is used on the client to make calls to server-side functions, it doesn't seem right to me. In collections you usually define methods like addUser inside Meteor.methods block. How am I supposed to call this function from the server-side?

Just restructure your method where you also name the function of the method, then you have two entry points into whatever code it is you'd like to execute:
addUser = function() {
...
};
Meteor.methods({'addUser': addUser});
Router.route('/sms/inbound', function () {
if (something) {
addUser({
name: "hello",
age: 20
});
}
}, {where: 'server'});

Meteor publication not working

I have Iron Router and quite simple pub/sub.
When publication just returns some specific item - everything works fine. But when it does some logic inside (looping thru another collection) - it doesn't work (Iron Router's loading template keeps showing forever, and looks like no data is coming thru DDP from this publication).
The code of pub:
Meteor.publish('ordersWithState', function(orderState) {
// if uncommented, this line works just fine
//return Orders.find({name:"C02336"});
var temp = Workflows.findOne({name:"CustomerOrder"});
if (temp) {
var stateUuid;
_.each(temp.state, function (state) {
if (state.name == orderState) {
return Orders.find({stateUuid: state.uuid});
}
});
}
});
Router config (if needed):
this.route('ordersList', {
path: '/orders/list/:orderState?',
loadingTemplate: 'loading',
waitOn: function() {
console.log("in ordersList waitOn");
var orderState = this.params.orderState || "Требуется закупка";
return [
Meteor.subscribe('ordersWithState', orderState),
Meteor.subscribe('allSuppliersSub'),
Meteor.subscribe('tempCol'),
Meteor.subscribe('workflows')
];
},
data: function () {
return Orders.find({});
},
onBeforeAction: function (pause) {
this.next();
}
});
The problem is with the logic of your publication here:
if (temp) {
var stateUuid;
_.each(temp.state, function (state) {
if (state.name == orderState) {
return Orders.find({stateUuid: state.uuid});
}
});
}
You are returning something from your inner _.each function, but you are not returning anything from the publication function. So the publication is not returning anything to Iron Router or responding with this.ready();.
It is not exactly clear to me what you want to publish - an array of cursors or perhaps an Orders.find() with an $in: [arrayOfItems]? In any case Iron Router should work fine once the publication is fixed.

iron router syntax: onAfterAction

Router.route('/courses/:_catalog', function () {
var courseCatalog = this.params._catalog.toUpperCase();
Meteor.subscribe("courseCatalog", courseCatalog);
this.render('CourseDetail', {
to: 'content',
data: function () {
return Courses.findOne({catalog: courseCatalog});
}
});
}, {
onAfterAction: function() {
if (!Meteor.isClient) {
return;
}
debugger
var course = this.data(); <======
SEO.set({
title: "course.catalog"
});
}
});
In the above code, please look at the debugger statement. I want to access the data but it seems I am doing something wrong because this.data doesn't exist. I also tried Courses.find().fetch() but I only get an empty array inside onAfterAction. What's the right syntax and what am I missing?
It needs to be inside a this.ready() block:
onAfterAction: function() {
if (this.ready()) {
var course = this.data();
...
}
}
You need to subscribe to data first. Have a look at the waitOn function to do this. The server only sends the documents you subscribed to, and since you didn't subscribe, Courses.find().fetch() returns an empty array.
Also, don't put SEO stuff in onAfterAction. Put it in onRun which is guaranteed to only run once.

Session object inside global template helpers

Session.set('coursesReady', false); on startup.
UPDATE:
I made it into a simpler problem. Consider the following code.
Inside router.js
Router.route('/', function () {
Meteor.subscribe("courses", function() {
console.log("data ready")
Session.set("coursesReady", true);
});
}
and inside main template Main.js
Template.Main.rendered = function() {
if (Session.get('coursesReady')) {
console.log("inject success");
Meteor.typeahead.inject();
}
The message "inject success" is not printed after "data ready" is printed. How come reactivity does not work here?
Reactivity "didn't work" because rendered only executes once (it isn't reactive). You'd need to wrap your session checks inside of a template autorun in order for them to get reevaluated:
Template.Main.rendered = function() {
this.autorun(function() {
if (Session.get('coursesReady')) {
console.log("inject success");
Meteor.typeahead.inject();
}
});
};
Probably a better solution is to wait on the subscription if you want to ensure your data is loaded prior to rendering the template.
Router.route('/', {
// this template will be rendered until the subscriptions are ready
loadingTemplate: 'loading',
waitOn: function () {
// return one handle, a function, or an array
return Meteor.subscribe('courses');
},
action: function () {
this.render('Main');
}
});
And now your rendered can just do this:
Template.Main.rendered = function() {
Meteor.typeahead.inject();
};
Don't forget to add a loading template.
To Solve Your Problem
Template.registerHelper("course_data", function() {
console.log("course_data helper is called");
if (Session.get('coursesReady')) {
var courses = Courses.find().fetch();
var result = [ { **Changed**
name: 'course-info1',
valueKey: 'titleLong',
local: function() {
return Courses.find().fetch();
},
template: 'Course'
}];
Session.set('courseResult', result); **New line**
return Session.get('courseResult'); **New line**
,
Explanation
The answer is at the return of the helper function needs to have be associated with reactivity in order for Blaze, template renderer, to know when to rerender.
Non-reactive (Doesn't change in the DOM as values changes)
Template.Main.helpers({
course_data: UI._globalHelpers.course_data ** Not reactive
});
Essentially: UI._globalHelpers.course_data returns an array of objects which is not reactive:
return [
{
name: 'course-info1',
valueKey: 'titleLong',
local: function() {
return Courses.find().fetch();
},
template: 'Course'
},
Reactive
From Meteor Documentation:
http://docs.meteor.com/#/full/template_helpers
Template.myTemplate.helpers({
foo: function () {
return Session.get("foo"); ** Reactive
}
});
Returning Session.get function to Blaze is reactive; thus, the template will change as the values changes.

meteor iron:router Blaze.ReactiveVar calling multiple times

I have a route I call many times. I have to subscribe two collections for having all datas, here's a snapshot:
var one = new Blaze.ReactiveVar(false);
var two = new Blaze.ReactiveVar(false);
this.route('stopIndex', {
path: '/stop/:section/:stop_id',
waitOn: function() {
Meteor.call('getTripIdsForStop', {
stop_id: this.params.stop_id,
from: fromNow(),
to: toMax(),
db: prefix
}, function(err, ids) {
DEBUG && console.log('TRIP_IDS:', ids);
Meteor.subscribe(prefix + '_trips', {
trip_id: {$in: ids}
}, function() {
one.set(true);
});
Meteor.subscribe(prefix + '_stop_times', {
trip_id: {$in: ids}
}, function() {
two.set(true);
});
});
return [
function () { return one.get(); },
function () { return two.get(); }
];
},
The first time I call the route, all goes fine. The second time, the one and two vars are already setted to true so the waitOn doesn't wait and I get a no data message on my template for some seconds, until collections responds. I've tried putting on the first lines of waitOk method:
one.set(false);
two.set(false);
but this makes the waitOn to wait forever. Am I doing something wrong or missing something? Thanks for the help.
I've solved this way:
Router.onStop(function() {
one.set(false);
two.set(false);
});
that invalidates ReactiveVars and will wait. I've also moved all code from waitOn to data. Now the waitOn is like this:
return [
function () { return one.get(); },
function () { return two.get(); }
];

calling one of multiple services in angularJS $resource

Is there anything wrong with this code where I am trying to have one service method point to different restful services?
var phonecatServices = angular.module('phonecatServices', ['ngResource']);
phonecatServices.factory('Phone', ['$resource',
function ($resource) {
return {
pList: $resource('/:url/:phoneId.json.htm', {}, {
query: { method: 'GET', params: { url: 'MyAngularScripts', phoneId: 'jsonPhonedata' }, isArray: true }
}),
pDetail: $resource('/Content/PhonesData/:phoneId.json.htm', {}, {
query: { method: 'GET', params: { phoneId: $routeParams.phoneId }, isArray: false }
})
};
}]);
Then in my controller I call the pList like this:
$scope.phones = Phone.pList.query();
The service method doesnt get called with any of the code above. However if I change the service to this:
var phonecatServices = angular.module('phonecatServices', ['ngResource']);
phonecatServices.factory('Phone', ['$resource',
function ($resource) {
return $resource('/:url/:phoneId.json.htm', {}, {
query: { method: 'GET', params: { url: 'MyAngularScripts', phoneId: 'jsonPhonedata' }, isArray: true }
});
}]);
and call from the controller like this:
$scope.phones = Phone.query();
IT works. What is wrong with the service where I have multiple restful calls declared? SOmething wrong with the way its configured or the way I am calling it?
The 1st approach should be working fine as well.
The only oroblem is that you are trying to access a property of $routeParams, without first injecting it via DI, thus resulting in an Error being thrown.
If you correct this, everything should work as expected.
