This article covers the rudiments that need to be known about Ruby on Rails. Before going further, let us look at what Ruby and Rails are.
What is Ruby?
It is a combination of three concepts; Perl’s pragmatism, Python’s ease of use and learning, and Smalltalk’s conceptual elegance. Ruby is a high level programming language, it is interpreted like Python, Perl, Tcl/TK, and it is object oriented like Eiffel, Java, Ada, and Smalltalk.
Why you should opt for Ruby
The origin of Ruby can be traced to Japan, and it is now gaining popularity in Europe and US as well. Ruby is gaining popularity due to some factors, below are some of the reasons for its popularity:
• It contains less coding with lesser bugs
• It has a thriving community where members can enjoy help from each other
• It is not difficult to learn when compared to other software.
• It has open source i.e. very liberal license
• It can be extended very easily
• It has libraries that are very rich, and
• It is object oriented.
Although there are many reasons why it is good to use Ruby, It will be unfair to mention they bottleneck attached to it. Before you implement Ruby, here are some drawbacks you have to consider –
• Threading model. Ruby does not make use of native threads. Ruby threads do not run on native OS threads, but rather, it is simulated in the VM.
• It has the issue of performance. Although it rivals Python and Perl, it still remains an interpreted language thus cannot be compared with high level programming languages such as C++ or C
Having looked at what Ruby is, its benefits, and drawback, let us now look at Rails.
What is Rails?
Below are some of the things you need to know about Rails
• It is a web application that is extremely productive
• It is written by David Heinemeier Hansson in Ruby
• It is much faster to use Rails to develop web application. At least 10 times faster than a typical Java framework.
• It is an open-source Ruby framework used to develop database-backed web application.
• It does not require any compilation phase.
• Your code is configured with Database Schema
• This is all that is needed to design a database driven web application. It works with Model View Controller pattern.
• Fewer lines of code are required compared to other framework
• What it means for a framework to be fully stacked is that the layers are created to work coherently together with few code
Rails has many features that enables you to be more productive, and these features build on one another. Some the features are:
• Active Record
• Convention over configuration
• Built-in testing.
There are three different default environments that Rails offers: testing, development, and production. They behave differently from each other, which makes entire software development process much easier. For instance, Rails builds a new copy of the testing database whenever a test is carried out.
