Skill-Based Interview Questions to Hire Ruby on Rails Developers
How do you ensure efficient and optimized database queries in Ruby on Rails?
To optimize database queries in Rails, focus on using ActiveRecord's eager loading to avoid N+1 query problems, indexing the databases where necessary, and implementing query caching. Regularly reviewing and refactoring queries and strategically using methods like 'includes' and 'joins' significantly improves database efficiency.
In Ruby on Rails, how do you manage user authentication and ensure security?
Typically, Devise Gem is used for managing user authentication in Rails due to its modular nature and ease of integration. Security is maintained by enforcing strong password standards, incorporating two-factor authentication, securely encrypting sessions, and updating authentication libraries.
What are the key security practices in a Ruby on Rails application?
Key security practices in Rails involve using 'strong parameters' to prevent mass-assignment vulnerabilities and implementing CSRF tokens in forms. It also focuses on robust user authentication and authorization, often using gems like Devise. Regularly updating Rails and its dependencies and using HTTPS for data transmission is essential for maintaining security.
