activerecord

What problem does it solve?

Rails developers often struggle to design robust ActiveRecord models, implement correct associations, write efficient queries, and maintain data integrity through validations, migrations, and performance-conscious patterns.

Core Features & Use Cases

• Associations: Model and optimize belongs_to, has_one, has_many, has_many through, and polymorphic relations with proper options and constraints.
• Validations & Callbacks: Enforce data accuracy and lifecycle hooks to ensure consistency across models.
• Queries & Eager Loading: Build expressive queries, apply scopes, and choose appropriate eager loading strategies to avoid N+1 problems.
• Migrations & Performance: Plan safe schema changes, add indexes, and use batch updates for large datasets.

Quick Start

Design an ActiveRecord setup with a User that has_many :articles, includes validations, and uses an efficient query to fetch recent articles with their authors.
