Router, find users count


#1

Hi, i will need to get a count of users, in before action section

Router.onBeforeAction(function() {
  if (! Meteor.userId()) {

    let firstBoot = Meteor.users.find({}).length
    console.log(firstBoot)
    firstBoot == 0 ? this.render('register') : this.render('login')

  } else {
    this.next();
  }
});

but firstBoot is undefined, i can try to use the Meteor.methods in my server code, and get user count in router using Meteor.call? 10Q :slight_smile:

try either Meteor.users.find().count() or Meteor.users.find().fetch().length

collection.find() returns a cursor, therefore length is undefined. count() counts a cursor or fetch() converts the resultset into an array.

Edit: you also need to have your users collection fully published in order to receive that count on the client.

i try it, count() method returned 0, but users in collection > 0

See my edit. You need to have the whole user collection published to be able to count on the client.

You have other options:

  • Publish a safe subset of the user information.
  • Publish just the counts
  • Calculate the count at the server and retreive via method

Meteor.users.find().count() works in my code. I am using the accounts-password package.

in onBeforeAction on iron router? when you are loggen in

I believe this hits the spot. So, using the tmeasday:publish-counts package, you can do the following.

Meteor.publish('userCount', function() {
  Counts.publish(this, 'user-count', Meteor.users.find());
});

Then, in your home or β€˜/’ route

waitOn: function() {
  return [Meteor.subscribe('userCount')];
}

Then, your code becomes

Router.onBeforeAction(function() {
  if (! Meteor.userId()) {

    let firstBoot = Counts.get('user-count');
    console.log(firstBoot)
    firstBoot == 0 ? this.render('register') : this.render('login')

  } else {
    this.next();
  }
});

This way, you do not have to publish the entire/part of β€˜user’ collection and only publish the information you need (the user count).
