Preface
1. What's so Awesome about Mongoid? 2. Mongoid Document Model FREE CHAPTER 3. Persisting Documents 4. Mongoid Relations 5. Mongoid Queries 6. Performance Tuning 7. Mongoid Modules Index

Chapter 4. Mongoid Relations

Now that we have seen how documents are stored, let's see how documents are related to each other. Mongoid tries to be as close to ActiveRecord relations as possible. In this chapter, we will see the basic relations that exist between documents:

  • One-to-One (1-1) relation

  • One-to-Many (1-N) relation

  • Many-to-Many (N-N) relation

  • Polymorphic relation

In addition to this, we will also learn about relations with embedded documents and how they are managed.
