let post=Post.findOne({'disabled':false});
console.log(post._id);

While using 

let post=Post.find({'disabled':false});
console.log(post._id)

It is showing undefined. Please help!

You are getting undefined because find() returns a cursor. It does not immediately access the database or return documents. Cursors provide fetch() to return all matching documents, map() and forEach() to iterate over all matching documents, and observe and observeChanges to register callbacks when the set of matching documents changes.

In this case you need to call fetch() on the cursor to all matching documents as an Array i.e.

let posts=Post.find({'disabled':false}).fetch();
console.log(posts[0]._id) // log the first element in the results set

or using forEach() to iterate the cursor:

Post.find({'disabled':false}).forEach(post => console.log(post._id));
