Mongoid is the official Object-Document Mapper (ODM) framework for MongoDB in Ruby, built on top of the official Ruby MongoDB driver. It provides ActiveRecord-like modeling, querying, and Rails integration for document-based persistence.
Use cases
- map Ruby classes to MongoDB documents
- use MongoDB models in a Rails app like ActiveRecord
- query MongoDB with a Ruby DSL instead of raw driver calls
- define associations and validations for document models
- migrate a Rails app from SQL to MongoDB
- manage nested documents and embedded associations in Ruby
When to choose
- you are building a Ruby or Rails application backed by MongoDB
- you want an ActiveRecord-like API for document data
- you need an officially supported, actively maintained MongoDB ODM
When to avoid
- your project uses a relational database instead of MongoDB
- you prefer lightweight direct driver access without an ORM layer
- you need an ODM for another language or framework
