Rails makes it super easy to model complex relationships in your applications. With its powerful Active Record associations, you can link your models together, allowing them to interact in a seamless and efficient way. Whether you’re working with one-to-one, one-to-many, or many-to-many relationships, Rails gives you the tools to handle these scenarios with minimal effort. Let’s dive deep into understanding how Rails associations work, tips to get the most out of them, and hacks that will make your coding smoother and more effective.

🔗 What Are Rails Associations?

Rails associations are a way to link Active Record models in your application. They let you define relationships between your models, enabling data interaction and queries across tables without manual SQL joins.

Rails provides several types of associations:

1. belongs_to
2. has_one
3. has_many
4. has_many :through
5. has_and_belongs_to_many

Each of these relationships models a different type of association in a database.
