[Solved] Noob publish and subscribe

help

This is my first crack at meteor so bear with me. I’m trying to create a collection for my menu system, so in /server/bootstrap.js, I have

Meteor.startup(function () {
  var Pages = new Meteor.Collection('Pages');
  if(Pages.find().count() === 0) {
     Pages.insert( {'name': "Buildings", 'icon': "<i class='mdi-social-domain'></i>", 'route': 'buildings', 'include_in_menu': true, 'protected': false} );
     Pages.insert( {'name': "Map", 'icon': "<i class='mdi-maps-pin-drop'></i>", 'route': 'map', 'include_in_menu': true, 'protected': false} );
     Pages.insert( {'name': "Questions", 'icon': "Qu", 'route': 'questions', 'include_in_menu': true, 'protected': true} );
     Pages.insert( {'name': "Aggregations", 'icon': "Ag", 'route': 'aggregations', 'include_in_menu': true, 'protected': true} );
     Pages.insert( {'name': "Scenarios", 'icon': "Sc", 'route': 'scenarios', 'include_in_menu': true, 'protected': true} );
     Pages.insert( {'name': "Users", 'icon': "<i class='mdi-social-group'></i>", 'route': 'users', 'include_in_menu': true, 'protected': true} );
  }
});

Then in /server/publish.js, I have:

Meteor.startup(function () {
  Meteor.publish("site_pages", function() {
     if(Roles.userIsInRole(this.userId, 'admin')) {
        return Pages.find();
     } else {
        return Pages.find({ 'protected': false });
     }
  });
});

Then in /my_app.js, I have:

Meteor.subscribe("site_pages");

At the console and in my code, ‘Pages’ is undefined. I know this is something simple, but it escapes me how I get access to my 6 Pages.

you declared Pages inside a function with the var statement, which means that variable is scoped to the function.

Make sure you declare Pages in a file that can be read on server and client and without the var

I put

Pages = new Meteor.Collection(“Pages”);

at the top of /my_app.js (removing /server/bootstrap.js) and the application breaks with the following error

I20160118-12:07:37.690(-8)? Exception from sub directory id

if you share all of your relevant code, maybe someone can help you. Meteor.subscribe should only run on the client

Oh wait… you are correct. Pages is now getting through and I can see the variable Pages.

I think I have some other parts of my code that are not quite working.
Thank you for your help.
