Merging collections in Meteor

Answer 1

Idea 1 seems to work out of the box. I created a new meteor project and change it as follows:

test.js:

Users = new Meteor.Collection("users");
Posts = new Meteor.Collection("posts");

if (Meteor.isClient) {    
  Template.hello.array = function () {
      var a = Users.find().fetch()
          .concat(Posts.find().fetch());
      return _.sortBy(a, function(entry) { return entry.votes; });      
  };
}

if (Meteor.isServer) {
  Meteor.startup(function () {
      // code to run on server at startup
      Users.insert({name: "user1", votes: 1});
      Users.insert({name: "user2", votes: 4});
      Users.insert({name: "user3", votes: 8});
      Users.insert({name: "user4", votes: 16});

      Posts.insert({name: "post1", votes: 2});
      Posts.insert({name: "post2", votes: 4});
      Posts.insert({name: "post3", votes: 6});
      Posts.insert({name: "post4", votes: 8});

  });
}

test.html:

  



  {{> hello}}

This gives the expected list:

1 user1
2 post1
4 user2
4 post2
6 post3
8 user3
8 post4
16 user4

Then I did Users.insert({name: "new", votes: 5} in the console and got (reactively):

1 user1
2 post1
4 user2
4 post2
5 new
6 post3
8 user3
8 post4
16 user4
