![]() ![]() MongoTemplate.aggregate(aggregation, "products", ProductListDTO. In this chapter well describe the latter, using the dedicated nestjs/mongoose package. You can either use the built-in TypeORM module described here, which has a connector for MongoDB, or use Mongoose, the most popular MongoDB object modeling tool. List aggregateOperations = new ArrayList() Ĭriteria criteria = Criteria.where("type._id").in(typeIds.stream().map(t -> new ObjectId(t)).collect(Collectors.toList())) ĪggregateOperations.add(Aggregation.match(criteria)) Īggregation aggregation = Aggregation.newAggregation(aggregateOperations) Nest supports two methods for integrating with the MongoDB database. To find the multiple values, we can use the aggregation operations that are provided by MongoDB itself. ![]() The find () method returns a cursor of the result set and prints all the documents. My java code to execute the aggregation: List typeIds = Arrays.asList("618b99a3b4c24465b074b246", "60ad10ffc723877d8a977149") MongoDB provides the find () that is used to find multiple values or documents from the collection. Use the Select your language drop-down menu in the upper-right to set the language of the following examples. Public class Product String ProductType type Spring data mongodb generated 2 dimensional arrays for the OIDs in the $in json Step 5: Click on connect button, to connect and navigate to the Compass GUI Home Page. Step 4: After that, click Connect with MongoDB Compass and copy the provided connection string. Step 3: Click Connect for the cluster you want to connect. I was able to filter documents by multiple document Ids (primary key, not the nested object's object Id) in String value without any issues as Spring data mongodb converts the String values to oid: ] I would like to know how can we filter/retrive an object inside an array of multiple objects based on certain fields for eg. Step 2: To get the deployment connection string for an Atlas cluster, go to your Atlas cluster view. However spring data mongodb does not converts the String value to object Id in the match operation. MongoDB Compass : filter and query by date. However, sometimes you may want to filter some field, specifically an array field by a certain condition. Find objects in nested array, mongodb, compass. I would like to filter mongodb collection by multiple nested object's object Id in String with Mongodb aggregation match operation. Usually when you make queries in MongoDB, the returned result is the whole document with all the fields unless you make a projection. To use MongoDB Compass, you must install it on your local computer. ![]()
