Ruby on Rails

The Ruby on Rails for Web Development course aims to provide a thorough understanding of the Rails framework and its applications in building dynamic web applications.
This course covers the full spectrum of Rails development, including setting up the environment, understanding MVC architecture, working with models and databases using ActiveRecord, creating views and handling forms, and implementing authentication and authorization.
Participants will also learn to use Rails helpers, integrate libraries, and follow best practices for testing and deployment.
By the end of the course, learners will be equipped with the skills needed to develop, deploy, and maintain robust web applications using Ruby on Rails.
This course offers several key advantages for learners. It provides comprehensive skill development in Ruby on Rails, enabling participants to build and deploy scalable web applications efficiently.
Learners will gain hands-on experience with core Rails concepts, including MVC architecture, database interactions, and authentication mechanisms.
By engaging in practical projects and utilizing industry-standard libraries and tools, participants will enhance their career prospects in web development.
Additionally, the course emphasizes best practices for code organization, performance optimization, and security, ensuring that learners can create high-quality, maintainable applications.

Participants should have a basic understanding of programming concepts and familiarity with web development fundamentals.
Prior knowledge of Ruby programming is beneficial but not required.
Familiarity with HTML and CSS will help in understanding the view components, and a general grasp of databases and SQL is useful for working with ActiveRecord.
The course will begin with a brief overview of Ruby on Rails, making it accessible to those new to the framework.
