Find the total quantity of items meeting a specific criteria within a MongoDB database collection

I'm struggling to identify the issue in my query. My goal is to retrieve the count of "alerts" with the "resolved: false" field, so my query is :

Alertes.find({resolved: false}).count();

Unfortunately, it's returning 0 even though I have one entry in the collection with resolved set to false.

If anyone could assist me in identifying what mistake I may be making, I would greatly appreciate it.

Answer №1

I made the mistake of forgetting to include subscriptions in my IronRouter configuration file:

Router.route('/', {
  name: 'home',
  waitOn: function() {
    return [
      Meteor.subscribe('infosContainers'),
      Meteor.subscribe('infosMachines'),
      Meteor.subscribe('alertes'),
    ];
  },
  fastRender: true,
});

Appreciate the assistance provided!

Answer №2

Have you attempted this yet?

Alertes.find({resolved: false}).fetch().length

If you are executing this code on the client side, ensure that you have subscribed to this collection and have documents that match the filter you are using. Try querying all documents (without a filter) to confirm the presence of the documents with the specified query above, and observe the results:

Alertes.find().fetch()

If you cannot find any documents where the resolved property is set to false, then the query is functioning correctly, and the issue lies with your subscription.
