Mongoose populate sort

Mongoose How to sort .populate field. I'm work with an user/articles profile system. I have been using the .populate () to render the posts but I cannot get the articles sorted by the date they were created. I am using the createdAt variable as the main way of ordering the posts displayed The Mongoose API does seem to support sorting on populated fields, but there's a bug that breaks it entirely: https://github.com/Automattic/mongoose/issues/2202. You get a result, but it's just plain wrong. For small amounts of data, it's fine to sort the result array using Javascript Array.prototype.sort(). Keep in mind that this directly modifies the sorted array though There is no need to sort in the population because it only returns 1 item (there is no array of last messages). So the syntax would be: Chat.find().populate({ path: 'lastMessage' , select: 'timestamp'}) .sort('lastMessage.timestamp') .exec(function (err, chats) { //do something } Mongoose has a more powerful alternative called populate(), which lets you reference documents in other collections. Population is the process of automatically replacing the specified paths in the document with document(s) from other collection(s). We may populate a single document, multiple documents, a plain object, multiple plain objects, or all objects returned from a query. Let's look at some examples In Mongoose, a sort can be done in any of the following ways: Post.find({}).sort('test').exec(function(err, docs) { }); Post.find({}).sort([['date', -1]]).exec(function(err, docs) { }); Post.find({}).sort({test: 1}).exec(function(err, docs) { }); Post.find({}, null, {sort: {date: 1}}, function(err, docs) {.

node.js - Mongoose How to sort .populate field - Stack ..

Yeah it's very tricky unfortunately, because mongoose needs to sort the whole array rather than just the docs that its going to populate. It's really gnarly to get this right with things like limit and skip in populate, which is why we haven't made much progress on this front. Ideas for how this should work in that case are most welcome In Mongoose, a sort can be done in any of the following ways: Post.find({}).sort('test').exec(function(err, docs) { }); Post.find({}).sort({test: 1}).exec(function(err, docs) { }); Post.find({}, null, {sort: {date: 1}}, function(err, docs) { }); Post.find({}, null, {sort: [['date', -1]]}, function(err, docs) {. If we have an existing mongoose document and want to populate some of its paths, mongoose >= 3.6 supports the document#populate() method. Populating multiple existing documents If we have one or many mongoose documents or even plain objects ( like mapReduce output ), we may populate them using the Model.populate() method available in mongoose >= 3.6 In my research before doing any coding, I stumbled upon Model.populate(), a Mongoose method that you can use to essentially link documents across collections. This allows you to have a schema for.

the demo described in the official mongoose's documentation about a populate with sort options doesn't work (using mongoose ^5.9.3). here is the link https. MongoDB sort () In MongoDB, sorting is done by the sort () method. The sort () method consists of two basic building blocks. These building blocks are fields to be sorted and the sort order. The sorting order in MongoDB is defined by either a one (1) or a minus (-1). Here the positive one represents the ascending order, while the negative one. Using mongoose, we can get an output where all the documents are sorted in an order. The order can be ascending or descending. We can specify the order. The documents can be sorted according to a single field or even, we can sort documents according to multiple fields.

@jericopulvera sure, but you can use Model.populate to populate all the created documents, that will use one query: https://mongoosejs.com/docs/api.html#model_Model.populate. Company.populate(docs, { path: '_company' } 'selectPopulatedPaths': true by default. Set to false to opt out of Mongoose adding all fields that you populate() to your select(). The schema-level option selectPopulatedPaths overwrites this one. 'typePojoToMixed': true by default, may be false or true. Sets the default typePojoToMixed for schemas Thanks for this great new feature! Virtuals Populate are very useful in our case to dynamically populate from a TTL collection. One issue though is it seems its not possible to limit the documents that are populated. Suppose we have a User collection where user sessions are stored in a separate TTL collection. I want the 5 most recent sessions. Mongoose has a more powerful alternative called populate (), which lets you reference documents in other collections. Population is the process of automatically replacing the specified paths in the document with document (s) from other collection (s). We may populate a single document, multiple documents, plain object, multiple plain objects. Mongoose has an awesome method populate to help us. We define refs in ours schema and mongoose uses those refs to look for documents in other collection. Some points about populate: If no document is found to populate, then field will be null. In case of array of documents, if documents are not found, it will be an empty array. You can chain populate method for populating multiple fields. If.

Mongoose v5.12.14: Query Populatio

  1. From Mongoose docs on lean By default, Mongoose queries return an instance of the Mongoose Document class. Documents are much heavier than vanilla JavaScript objects, because they have a lot of internal state for change tracking. Enabling the leanoption tells Mongoose to skip instantiating a full Mongoose document and just give you the POJO

Mongoose populate doesn't behave like conventional SQL joins. When there's no document, story.author will be null. const stories = Story.find().sort({ name: 1}).populate({ path: 'fans', options: { limit: 2} }); stories[0].fans.length; // 2 stories[1].fans.length; // 0. That's because, in order to avoid executing a separate query for each document, Mongoose instead queries for fans using.

Sets the sort order If an object is passed, values allowed are asc, desc, ascending, descending, 1, and -1. If a string is passed, it must be a space delimited list of path names. The sort order of each path is ascending unless the path name is prefixed with - which will be treated as descending In this example, sort order may be inconsistent, since the borough field contains duplicate values for both Manhattan and Brooklyn. Documents are returned in alphabetical order by borough, but the order of those documents with duplicate values for borough might not the be the same across multiple executions of the same sort. For example, here are the results from two different executions of. I wanted to share a little journey I went down not too long ago.
