Ruby is a high-level programming language made in Japan. It is object-oriented like Java, Eiffel, Ada, and other programming languages and is interpreted like Perl and Python. It is open-source and easy to learn.
ERB OR EMBEDDED RUBY: Embedded Ruby or ERB is a Ruby program by Seki Masatoshi. With ERB, a developer can input Ruby codes in an HTML file. When ERB reads the Ruby code, it starts executing it. To run a Ruby code in an HTML file, you need to enclose it between <% and %>. To enable printing of the code result, you need to enclose it between <%= and %>.
RUBY GEM : A gem is a library in Ruby. It consists of a particular functionality and also any files or assets that are related to the functionality. It can be used for handling currency, integrating credit card processing, and so on. It reduces the amount of coding for developers because developers no longer have to write it themselves.
Rails: Developed by David Heinemeier Hansson, Rails is a web application framework in Ruby. Rails makes web application development faster than any typical Java framework. It is open-source and free for use.
Because of this feature rich nature of Ruby On Rails, there has been a huge demand to hire Ruby On Rails developer among the companies to work on their projects.
Ruby on Rails aims to emphasise two principles: Conversion over Configuration (CoC) and Don’t Repeat Yourself (DRY)
Convention Over Configuration: This means that Ruby on Rails web developers need to specify the unconventional parts of the application only. Convention over Configuration reduces the number of codes and in turn, makes it less repetitive. For instance, if a model has a class sale, by default, the corresponding table in the database is “sales” however, if a developer wants the table to be “products sold” and not “sales” he need to write codes for it.
Don’t Repeat Yourself: This means that the information located is not repeated. For instance, if a developer uses Rails’ Active Record module, he need not specify the names of the database columns in the class definitions. Ruby on Rails can automatically retrieve the information from the database that is based on the class name.
MVC Architectural Support: Ruby on Rails is based on Model-view-controller architecture.
Library Facility: Ruby on Rails comes with many libraries that simplify the coding process for developers. Developers can quickly perform tasks like sessions management, form validations, and so on.
Metaprogramming: Ruby on Rails uses metaprogramming to write programs. It also uses code generation by the process is not as extensive as other frameworks. It combines both metaprogramming and code generation and makes the process easier.
Active Record: Active Record is a Rails framework. This framework saves objects into the database by locating them. It finds the columns in a database schema and uses metaprogramming to attach them to your domain objects.
Automatic Scaffolding: Sometimes, Ruby On Rails web developers need to create temporary codes before developing an app to check how significant components function in collaboration. Rails automatically creates these codes and make the task easier for you.
Automated Testing: Rails has a built-in testing facility. It creates automated tests. You can also extend these tests by using Rails support codes, harnesses and fixtures.
Three Environment: Rails provides three environments by default to facilitate web development for developers. These are development, testing and production.
AJAX Library: Ruby on Rails also comes with AJAX library functions. It can generate AJAX codes automatically.
Programming Conventions: Ruby on Rails comes with some simple programming Conventions instead of XML configuration files. These conventions can be used for specifying the parameters of configuration.
Customised URL: With Ruby on Rails, developers can quickly generate custom URLs that are Search Engine Friendly.
Debugging: The programming language also facilitates debugging. It provides error logs and makes debugging easier.
Components: Components are used for storing reusable codes. They can also be used to modularize templates
E-commerce Website: For e-commerce websites, some of the significant concerns are performance, security and user experience. This is why Ruby on Rails is perfect for building such websites. It is a highly stable framework which also ensures a high level of website performance. When you create a website using RoR, it is safe from SQL injections, cross-site request forgery, cross-site scripting, and other such attacks. The framework comes with some powerful security mechanisms that protect the website. At the same time, Ruby Gems has several e-commerce elements like payment gates, email marketing solution, inbound marketing software, and so on that help to create a satisfying user experience.
SaaS: Ruby on Rails is perfect for Software-as-a-Service products. These web applications need to be fast, secure and scalable. They depend on fast APIs so that your server can communicate and exchange data without any hassle. Rails is embedded with REST or Representational State Transfer architecture that helps in developing APIs. Rails also has powerful debugging and testing tools which ensures the development of glitch and error-free websites.
A Ruby on Rails developer is someone who uses Ruby language and Rails framework to develop back-end components for the server-side of the website or web application. Such a developer helps the front-end developers to integrate the back-end components with the front-end ones while developing an app.
Quick Coding: Ruby on Rails helps in making a cleaner codebase. Developers can also reuse existing components. It makes the coding process faster.
Cost-Effective: Ruby on Rails has many automated features such as automated testing, automated scaffolding, and so on. These features reduce the work of the developers and make web application development highly cost-effective.
Open-Source: Ruby on Rails is an open framework. It also has a host of open-source libraries. Open-source means developers can use it for free and also learn it for free. It also has a good community support base for developers.
Do you want to hire a Ruby on Rails developer for your enterprise? You should know what his roles and responsibilities are before you start the hiring process. There are three levels of Ruby on Rails developer- Beginner, mid-level and experienced. Here’s what they do:
Beginner: At the beginner or entry-level, a developer has several duties like setting up the environment for rail, managing databases, handling requests, so on. He or she must perform all the essential tasks required in Ruby on Rails-based applications.
Mid-Level: A mid-level developer must perform all the functions of an entry-level developers. Additionally, he or she must also have proficient knowledge of Active Record Associations, Object Orientation and Design Patterns.
Experiencedl: An experienced Ruby on Rails developer must be proficient in Ruby Metaprogramming and database modelling. He or she must also be skilled in planning, estimating and monitoring the applications. He or she must have analytical skills as well for identifying and fixing performance-related problems.
Ruby Syntax: You need to know how to code essential parts of the language such as classes, modules, loops, conditional statements, and so on.
OOP Programming: You need to know Object-oriented Programming and its various concepts like modules, classes, inheritance, objects, composition, and so on.
Active Record: You must be proficient in using Active Record and know about its migrations, validations, and other useful components.
MVC: Since Ruby on Rails is based on the MVC structure, you must know the several layers of MVC and the functions that they perform.
API and JSON: Knowledge of API and JSON is essential because Ruby on Rails is commonly used as an API provider as well.
HTML, JavaScript and CSS: A Ruby on Rails developer must also be proficient in some of the commonly used programming languages like HTML, JavaScript and CSS. These languages will help you work on the front-end of the website or web application.
SQL, MySQL and PostGreSQL: These three are commonly used database engines. You must know how to read logs using SQL. You must also know how to work with MySQL and PostGreSQL to setting them up in local machines.
GIT and GitHub: GIT is used to manage codes. You should know how to use GIT to manage the codes that you create. GitHub is a project management tool. Knowing GitHub is an added advantage in a Ruby on Rails developer.
The Ruby Association certifies the Ruby Programmer examinations. Theses exams are specifically aimed at engineers and developers who develop Ruby-based systems, system proposals and for those who teach Ruby. Currently, there are two levels of qualification. These are:
Ruby Association Certified Ruby Programmer Silver version 2.1: This is a certification for basic level skills. The certified programmer knows the background, classes, objects, grammar and standard Ruby libraries.
