Retrieve an undefined post using the Posts.findOne() method

As a newcomer to Meteor, I decided to delve into the Discove Meteor Book. However, I encountered some difficulties when trying to follow its instructions in Chapter 4 on collections:

  • Initially, I struggled with opening two browser console windows simultaneously as instructed. It seemed that the system only allowed one console window to be active at a time.
  • Subsequently, I proceeded with just one browser console window. Nevertheless, upon running Posts.findOne(), instead of retrieving {title: "A new post", _id: LocalCollection._ObjectID}; it returned "undefined." This was perplexing as I had defined
    Posts = new Mongo.Collection('posts')
    ; within posts.js file located under the lib folder, meant to work on both client and server sides.

Can anyone shed light on why this is resulting in "Undefined"?

Answer №1

Similar to the "insecure" package, every fresh Meteor application automatically includes the "autopublish" package.
Once you execute the command meteor remove autopublish, you must publish your collection data and subscribe to it manually. Failure to do so will result in no records being displayed since the client does not fetch data from the server, enhancing security protocols in Meteor.

To resolve this issue: Re-add the "autopublish" package using meteor add autopublish and then inspect the browser console for published records.
