Introduction to Ruby on Rails
Transcript of Introduction to Ruby on Rails
Being a full-stack framework means that all layers are built to work seamlessly together
Less Code. Requires fewer total lines of code than other frameworks spend setting up their XML configuration files. Convention over Configuration Rails shuns configuration files in favor of conventions, reflection and dynamic run-time extensions. Your application code and your running database already contain everything that Rails needs to know! Rails Strengths A High Level Programming Language like Perl, Python, Tcl/TK.Object-Oriented Like Smalltalk, Ada, Java.
Originated in Japan and Rapidly Gaining Mindshare in US and Europe.
Created by Yukihiro Matsumoto or fondly known as Matz Ruby is becoming popular exponentially in Japan and now in US and Europe as well. Following are greatest factors: Easy to learn
Very easy to extend
Less Coding with fewer bugs
Helpful community An extremely productive web-application framework. Written in Ruby by David Heinemeier Hansson.You could develop a web application at least ten times faster with Rails than you could with a typical Java framework.An open source Ruby framework for developing database-backed web applications. ActiveRecord Metaprogramming techniques use programs to write programs. Ruby is one of the best languages for metaprogramming, and Rails uses this capability well. Rails also uses code generation but relies much more on metaprogramming for the heavy lifting. Rails introduces the Active Record framework, which saves objects to the database. The Rails version of Active Record discovers the columns in a database schema and automatically attaches them to your domain objects using metaprogramming. Metaprogramming Built-in testing Rails creates simple automated tests you can then extend. Rails also provides supporting code called harnesses and fixtures that make test cases easier to write and run. Ruby can then execute all your automated tests with the rake utility.
