Mongoose query nested documents greater or less a certain date

Question

How dow I query comments greater than or less than a certain date...

Here is my Schema with Post model and a Comment model:

var mongoose = require(\'mong         


        

Answer 1

Use dot notation to reach inside the embedded array docs. For example, to query for the Post comments with a created_at between date1 and date2:

Post.find({ "comments.created_at": { $gt: date1, $lt: date2 }}, function (err, docs) {
     ...
});

UPDATE

Thanks for the edit; now I understand that you're trying to to filter the comments of single post by their created_at date. You can't do that directly with MongoDB queries, but I believe you can do it with the 2.2 aggregation framework if you're at that version. Take a look at the discussion of this feature request on Jira for examples.
