Rails is a web application framework implemented in Ruby that streamlines the creation of CRUD-oriented web pages through its MVC structure without the need for extensive configuration. It emphasizes principles such as convention over configuration and the DRY (Don't Repeat Yourself) philosophy, making it a productivity enhancer despite its learning curve. Key features include database migrations, code generators, and integrated functionalities like database access and testing.
Quick Start: Rails
- 1. Quick Start: What is Rails? By David Keener http://www.keenertech.com
- 2. What It Is … and Isn’t It’s a tool It’s optimized to create web pages quickly It’s MVC without config files It’s a productivity enhancer It’s got a learning curve It’s not magic It’s not a silver bullet It’s not going to replace Java for all applications Rails is a framework implemented in the Ruby object-oriented language that facilitates the creation of web sites, particularly CRUD-oriented (create, read, update & delete) web pages.
- 3. It’s a Full Stack Framework Rails provides an integrated full stack framework. J2EE provides similar functionality with a variety of separate frameworks / tools (each with their own learning curves).
- 4. The Rails Philosophy Convention over configuration Do not repeat yourself (DRY) The 80/20 Rule: Rails implements 80% of the functionality that most users need; the other 20% is your application Corollary to the 80/20 Rule: You have the power to extend the framework yourself Philosophy separates Rails from Java. Where Java favors solution completeness, Rails favors simplicity and speed.
- 5. Primary Rails Features Migrations: Facilitates DB maintenance Code Generators: Get up-and-running quickly with scaffolding (replace it later) Object-Relational Mapping: Uses ActiveRecord to automatically generate class methods based on database lookups MVC: No configuration required; just follow the Rails conventions Integrated Features: Database access, AJAX, Testing, Text/HTML emails, etc.
