MongoDB Drivers for Ruby
Ruby became very popular after release of rails framework. This language is known for its simple syntax. It provides direct interfaces to MongoDB. It also provides an efficient way to map Ruby objects to MongoDB entities.
Key features
- Ruby Driver: The mongodb ruby driver provides a native Ruby implementation.
- ActiveRecord integration: It seamlessly integrates with Ruby on Rails’ ActiveRecord.
Example Code
Ruby
# Import the 'mongo' gem require 'mongo' # Create a new MongoDB client instance with the specified connection string client = Mongo::Client.new('<connection_string>') # Access the default database for the MongoDB connection database = client.database # Access the 'test_collection' collection within the default database collection = database[:test_collection] # Find the first document in the collection where the "key" field has the value "value" result = collection.find('key' => 'value').first # Print the result to the console puts result |
Output:
If matching document is found:
{"_id"=>BSON::ObjectId('5f8a74b7c35e43ca756466f4'), "key"=>"value", "other_field"=>"some_value"}
if not found:
NIL
MongoDB Drivers For Different Languages
MongoDB is a NoSQL database that is widely used for storing and managing both complex and larger data. For good integration between applications and the MongoDB database, it provides drivers that allow the developer to interact with the database using the programming language of their choice. In this article, we will see different drivers of MongoDB which are popularly used.
Programming Languages supported by MongoDB are C, C++, C#, Go, Java, Kotlin, Node.js, PHP, Python, Ruby, Rust, Scala, and Swift. We will understand each one of them more easily along with their code implementation
