Before getting into the subject, it is important to clarify that Ruby and are not the same . Ruby is a programming language that emerg in 1993 at the hands of Yukihiro Matsumoto. It was creat due to the complexity of other languages such as Java and C++. It is flexible and precise , which makes it possible to organize written code more efficiently. The syntax, on the other hand, is bas on code blocks , which avoids errors when changing instruction lines. However, the Ruby language did not rise to international fame until 15 years later, in 2008, five years after being combin with a call Rails. This combination result in the framework known as Ruby on Rails (RoR) , creat by David Heinemeier Hasson in 2003 and very popular among developers in recent years for its simplicity and its foundation in .
Rails extends the Ruby language in the same way that .NET, Spring, or Django extend C#, Java, or Python, respectively .
What is Ruby on Rails and what is it us for?
Considering that Ruby on Rails’ own website defines it as “a framework for building web applications that access databases”, you can get a clear idea of what Ruby on Rails is us for … But is this enough to understand this tool?
There are many uses for Ruby on Rails in a company , we only have to see what it has been us for before: Twitter, Basecamp, Hulu, Xing, etc., and this is bas on multinationals. If we could use this same technology in a smaller business, with a small investment, wouldn’t it be a good idea?
Ruby on Rails: Its Principles and the MVC Pattern
Looking for other quality data to promote email marketing lists and contacts by country, you’ve come to the right place. As a result, you country email list get better quality active data at a lower price. A database management system is a structur form of collection that comes with the final data. Email contact lists are a powerful resource for understanding communication patterns and improving marketing strategies.
How the MVC pattern works
But how does the MVC pattern work? When the user makes a request to the software, it is the controller that responds to the request. The controller then asks the model for all the information relat to the request, images, text, videos, etc., which it looks for in the database and sends to the controller. Finally, the controller sends the information receiv to the view, which will be responsible for organizing and building it so that it can be view respecting the styles establish by the author at the time.
Ruby on Rails is bas on two fundamental principles:
1.- Don’t repeat yourself (DRY) . According to this principle, Ruby on Rails developers must avoid code duplication.
There are a large number of these gems that
2.- Configuration convention : generators create a directory tree that organizes the project structure. Developers can use configuration files to specify the parameters necessary for the correct operation of the project. This how to design an online store cart correctly: instructions and … means that a model call “User” will be automatically link to the “users” table in the database. However, if the table does not follow the convention, it must be specifi manually as follows: set_table_name “users_admin”. “ Thus, when designing an application from scratch without a pre-existing database, following Rails conventions means using less code .”
3.- Finally, there is a motto among developers that, although it is not a principle per se, could be includ among them: “ Test all the f*cking time ” (TATFT), which, translat in the softest possible way, would be “test all the time ”. This framework uses the Test Driven Development (TDD) strategy. This strategy is bas on writing the tests before starting to write the request functionality.
Open Source Libraries or Gems
Ruby on Rails libraries, commonly known as gems for their connection to Ruby, help solve programming problems make the work of developers easier. can be download and install completely free of charge . While they all greatly facilitate software development in very different ways, six of them stand out above the rest.
Software development with Ruby on Rails
- a gem widely us in projects with a lot of visual content. It greatly facilitates the integration of images in latest bulk sms development, also allowing the modification of format and size, among other things.
- allows dividing elements into pages in a very visual way. It also offers the possibility of applying different templates depending on the client’s tastes or nes.
- helps create friendly URLs. Very necessary for projects that aim to get the most out of SEO positioning.
Great apps develop with Ruby on Rails
- Twitter : Although it has been built on Java since 2011, the app for one of the most famous social networks on the current scene was initially built on Ruby on Rails, and by a team of just two people.
- Kickstarter and IndieGoGo : the applications of the two major crowdfunding platforms are built on this framework .
- Soundcloud : Like Twitter, the leading community for podcasts and free music, which receives more than 175 million visits per month, initially develop its application in RoR. Although it later began using the Scala language, the app still retains parts of the Ruby code.
- Twitch : Ruby on Rails is also present in the app of the most us platform currently for live video game broadcasting.
- Groupon : The leading website for deals and discount coupons also has an application built on Ruby on Rails and in which more than 35 million people are register.
Advantages of Ruby On Rails
- Ruby on Rails is a framework that greatly increases productivity because it is bas on agile methodologies. Many developers call it the “ quintessential agile framework . ”
- As stat before, RoR is a framework that is bas on the Model-View-Controller pattern. By being able to divide the development parts, project scalability is simplifi, which greatly benefits developers by allowing them to save resources.
