How to get the _id of posts that are instantiated in posts_list?

I need to get the _id of all post_item being displayed in Telescope. It is not the posts_itens that are in the Collection but those being displayed.

Using Google Translate.

Solution

  • You can use cursor.map(), if you are trying to get an array with _id values of post_item elements:

    var postIdsArr = Posts.find({}, {
    _id: 1
}).map(function(post) {
    return post._id;
});
