Unable to retrieve a collection within Angular-Meteor framework

I'm currently facing challenges while working with data from a Collection in Angular-Meteor as I struggle to access it successfully.

Inside lib/collections.js, I have defined the collection:

UserMeta = new Mongo.Collection('userMeta');

In the server/publish.js file, it is published as follows:

Meteor.publish('userMeta', function() {
  return UserMeta.find();
});

Subscribing to it in my client code located at client/scripts/controllers/settings.controller.js:

angular
  .module('App')
  .controller('SettingsCtrl', SettingsCtrl);

function SettingsCtrl($scope, $reactive) {
  $reactive(this).attach($scope);
  this.subscribe('userMeta');
  //...
}

Exploring different subscription methods, I've decided to follow the most recent syntax for version 1.3.2 of Angular-Meteor: Subscribe API

Despite these efforts, when attempting to view the entire content of the collection, an empty array is returned:

console.log(UserMeta.find().fetch()); // =[]

Similarly:

console.log(UserMeta.findOne()); // =undefined

Interestingly though, running these commands directly in my browser's client console yields the expected results.

If anyone could provide a brief example illustrating how to effectively work with collections in this context, I would greatly appreciate it. Coming from a background with (pure) Meteor, I find myself puzzled by the differences encountered in Angular-Meteor.

Answer №1

Give this a shot

Meteor.Methods

Incorporate the following code on your server-side script

Meteor.methods({
getUserMeta: function() {
 var data = UserMeta.find({}).fetch();
 return data;
}

Execute this method on the server side with the help of

Meteor.call('getUserMeta', function(err, data) {
   if (!err) {
     Console.log(data);
   } else {
     console.log("error");
   }
});

Answer №2

When calling console.log on a Collection object, it may not have data yet and will appear empty. To ensure you are logging the data after it has been fetched, consider using console.log within helper functions or checking if the collection is ready before logging:

// Example on the client-side
var subscription = Meteor.subscribe('latestData', Meteor.userId());
Meteor.autorun(function() {
  if (subscription.ready()) { ... }
});
