It works! Now we can comment on Guide articles.

To make the navigation a bit easier, It would be helpful if links to Previous and Next sections of the tutorial can also be added to the top of the page as well.

So how about the aldeed:collection2 package? I see you’re making use of aldeed:simple-schema, but then show only how to validate manually.

Does the collection2 package still work with Meteor 1.3? Is its use recommended? Any disadvantages to validating automatically rather than manually?

Is it still considered best practice to load the collection as a global variable?

Negative - you’d want to import it wherever you use it. Like in the todos example app:

Exporting:

github.com

meteor/todos/blob/01e0d749e1d4544a080e8dffaf9c0e8ff803e2f6/imports/api/lists/lists.js#L28


  }


  return super.insert(ourList, callback);
}
remove(selector, callback) {
  Todos.remove({ listId: selector });
  return super.remove(selector, callback);
}
}


export const Lists = new ListsCollection('Lists');


// Deny all client-side updates since we will be using methods to manage this collection
Lists.deny({
insert() { return true; },
update() { return true; },
remove() { return true; },
});


Lists.schema = new SimpleSchema({
name: { type: String },

Importing:

github.com

meteor/todos/blob/01e0d749e1d4544a080e8dffaf9c0e8ff803e2f6/imports/ui/pages/lists-show-page.js#L4


import { Template } from 'meteor/templating';
import { FlowRouter } from 'meteor/kadira:flow-router';


import { Lists } from '../../api/lists/lists.js';


import { listRenderHold } from '../launch-screen.js';
import './lists-show-page.html';


// Components used inside the template
import './app-not-found.js';
import '../components/lists-show.js';


Template.Lists_show_page.onCreated(function listsShowPageOnCreated() {
this.getListId = () => FlowRouter.getParam('_id');

@sashko I’ve been doing this recently, but now I can’t access that collection on the browser console. Is that supposed to be the case? Also, it seems slower which makes me feel like minimongo isn’t being used.

It’s definitely not slower, it’s exactly identical to before.

If you want to access from the console I’d suggest putting a:

global.Lists = Lists

near where you export it.

Interesting. I must be doing something else wrong, because it seems to be making the round trip call to the server db before updating my view. Thanks!

Did you import your methods on the client?

Yes, and tested that both the client and the server methods are being called. Can’t figure out where the latency is coming from, but only started happening today after I moved to modules.
