You can find more details to install Rails MongoDB for these versions here<\/a>.<\/p>\n\n\n\n\nRead More: How to install and use MongoDB with Rails 6<\/a><\/strong><\/p>\n<\/blockquote>\n\n\n\nOnce you finish the setup, start the MongoDB server. Here are some additional commands for that. To set up MongoDB:<\/p>\n\n\n\n
To start MongoDB use:<\/p>\n\n\n\n
$ sudo service mongod start<\/code><\/p>\n\n\n\nTo stop MongoDB use:<\/p>\n\n\n\n
$ sudo service mongod stop<\/code><\/p>\n\n\n\nTo restart MongoDB use:<\/p>\n\n\n\n
$ sudo service mongod restart<\/code><\/p>\n\n\n\nLet’s move to the Rails part now!<\/p>\n\n\n\n
Create a new rails application to use Ruby MongoDB. Make sure that you add –skip-active-record.<\/p>\n\n\n\n
$ rails new my_mongo_app --skip-active-record<\/i><\/code><\/p>\n\n\n\nIf you notice, there is no database.yml<\/i> and no sqlite3<\/i> gem is added automatically. Now we have to add two gems which will be a bridge for us between Rails and MongoDB.<\/p>\n\n\n\n
Add the following gems to Gemfile<\/i>.<\/p>\n\n\n\n
gem 'mongoid', '~> 6.0'<\/code>
gem 'bson_ext'<\/code><\/p>\n\n\n\nNow do bundle install<\/i>. Now we have to generate mongoid.yml<\/i> file which is similar to database.yml<\/i> file for us.<\/p>\n\n\n\n
Run the following command to generate MongoDB configuration files.<\/p>\n\n\n\n
rails g mongoid:config<\/code><\/p>\n\n\n\nNow update mongoid.yml<\/i> file based on your MongoDB configurations and create a database with rake db:create<\/i> Mongoid provides these generators to manage database with these rake tasks.<\/p>\n\n\n\n\nRead Also:\u00a0Extracting text from image <\/a>using<\/a> Google Cloud vision OCR with Ruby<\/a><\/p>\n<\/blockquote>\n\n\n\nTo add a model you can use scaffold and Mongoid will automatically add a module include Mongoid::Document<\/i> in that class. Here\u2019s the Rails scaffold example and code:<\/p>\n\n\n\n
rails g scaffold article name:string content:text<\/code><\/p>\n\n\n\nThis will generate all files as we usually have in normal scaffolding and you can access it from \/articles<\/i>.<\/p>\n\n\n\n
That’s it. Your Rails application is ready for use with MongoDB.
