We convert it to a regular expression meaning “any string that contains the search string”. In this code snippet, “query” is the search string. To make it more clear, suppose you have a user collection like this: ). In other words, for a given string, you would like to get users of which either one of those fields contain the string. Suppose you have a usercollection and you would like to search or filter users by first name, last name, or email.

MONGODB COMPASS MULTIPLE FILTERS HOW TO

If err = cursor.All(context.In this article, I will share with you how to filter by multiple fields on a collection in MongoDB. Let’s see how you can use it: if err := client.Ping(context.TODO(), readpref.Primary()) err != nil ) The MongoDB client provides a Ping() method to tell you if a MongoDB database has been found and connected. If multiple filters apply to a query, the filters must all specify the same type of projection or the query will fail. The mongo.Connect documentation contains more advanced configurations for creating a MongoDB client instance, including authentication. If the err value is not empty, it means there was an error (wrong credentials or connecting to a non-existent database), and you should terminate the application using panic(). Any time you make requests to a server (the database, in this case), you should create a context using context.TODO() that the server will accept.įinally, you checked errors in the database connection using the err variable returned from calling mongo.Connect().

Then, you created a client instance using the mongo.Connect() function and passed a Go context to it.

Here, you imported the mongo, mongo/options, and mongo/readpref modules from the Go driver into your application to connect to the local database.

Import the Go driver package into your application, then create a MongoDB client instance for a database on port 27017 (MongoDB’s default port).Ĭreate a file named main.go and save the following code in it: package main Please click on Map Filters below and Clear filters to see. In the terminal, type the following: go get go./mongo-driver/mongo

MONGODB COMPASS MULTIPLE FILTERS INSTALL

Install the MongoDB Go driver package in your project.

You are free to use any name for your package: go mod init mongo-with-golang Set up your development environmentĬreate a new Go project in your text editor or IDE and initialize your go.mod file. It provides functionalities that allow a Go application to connect to a MongoDB database and execute queries. The first step is to install the MongoDB Go driver, the official Go driver for MongoDB.

A Go development environment (e.g., text editor, IDE).
