Ruby on Rails is a full-stack web application framework written in Ruby. It allows developers to build database-backed web applications rapidly using conventions like MVC pattern and follows "convention over configuration" principle. Rails includes features like Active Record (ORM), validations, migrations, scaffolding, routing and helpers to help develop web applications quickly. Testing is an important part of Rails development using tools like RSpec, Factory Girl, Cucumber and Capybara.

Ruby on Rails Development Benefits and Pitfalls
Understanding how the many components of digital design and development are connected is crucial for web developers. Each pillar supports the span, much like a bridge, and if any one of them fails, the entire structure falls. Both poor design and poorly written code can obliterate even the most complex design solutions. Every component contributes to the final result, a user-friendly product.
We have provided you with some background information on the terms, procedures, and tools used in web development in previous posts. This article will carry on that theme. We're going to discuss one of the widely used web development tools, Ruby on Rails, and share some of its advantages and disadvantages with you.
brief history
A brief history will be presented first. Ruby is an open source, dynamic, object-oriented programming language with an emphasis on efficiency and productivity. The original version of the language, Ruby, which was created by Yukihiro "Matz" Matsumoto, was initially made available in the 1990s. Today, it provides power to popular services like Basecamp, Hulu, the original Twitter, and Living Social. Because Ruby offers a framework that supports a high level of developer flexibility, many businesses, including BBW, Cisco, CNET, IBM, JP Morgan, NASA, and Yahoo, employ it in some capacity.
The open-source Ruby on Rails web application framework is designed to increase programmers' long-term productivity. From his work on the project management tool Basecamp at the web application firm also known as Basecamp, David Heinemeier Hansson extracted Ruby on Rails. In July 2004, Hansson first made Rails available as open source. Even well-known companies like Amazon and eBay have Rails projects.
From my work on Basecamp, a project collaboration tool from 37signals, Rails (Ruby on Rails) was extracted. It was therefore driven by needs rather than predictions. And I think a large reason why we're doing so well right now is because of it. I didn't make an effort to consider what certain programmers could require for a dream job. I merely constructed what I required to complete my work cheerfully. David Heinemeier Hansson, the author of Ruby on Rails, is a different interviewee.
What is Ruby on Rails?
Model-view-controller (MVC) is how Rails apps work. This technique is utilized by numerous other web frameworks, including AngularJS (JavaScript), Django (Python), and CakePHP (PHP).Models, Views, and Controllers are the three components that make up the apps, according to this. These parts perform the following functions:
They include the functionality needed to modify and get the many types of data the app uses. A model is represented as a class in Rails. They are not low-level data types like strings or arrays.
Create the logic that connects views and models (and the data they are linked with). They perform input processing, make method calls, and send data to
Since its public unveiling in 2004, Ruby on Rails has taken the web development world by storm. Rails is an open-source framework, built using the Ruby programming language, that promotes high productivity and reduced development times for real-world web sites. This talk will provide a high-level tour of the features of Ruby on Rails. It will also show how this technology is being leveraged to create on-line businesses and web sites. You don't have to be a programmer to learn more about how Ruby on Rails can power your on-line business.
Lisp(Lots of Irritating Superfluous Parentheses)Pivorak MeetUp
My presentation is about Lisp, and its influences on ruby language.
Also speak about Lambda calculus and Turing machine. This is crucial for Lisp origins understanding.
Show major Lisp dialects. And speak a little about Emacs and Emacs Lisp.
Also I going to show project management in Common Lisp and describe CLOS (Common Lisp Object System).
Business-friendly library for inter-service communicationPivorak MeetUp
I’m going to share the experience of creating a platform-level client library for communication between internal services.
The talk partially covers topology and protocols related decisions we made.
But the main focus is the Ruby library that defines the inter-service communication framework using business-related abstractions.
Sergiy Kukunin has 9 years of Web Development career and 4 of them - with Ruby. Now he is freelancing and owns a tattoo studio. But the story he is gonna share with us this time is about being a Team Leader - all from a personal experience.
Ever wanted to lead a team?
Hear his sincere story, practical advice and tips how not to screw up.
The Saga Pattern: 2 years later by Robert PankoweckiPivorak MeetUp
When you split your application into multiple module how do you make them talk to each other? How do you make them react to changes happening in other parts of the system? How do you make them tell each other that something needs to be done? When should it happen? We will have a look what we can squeeze out of domain events being published in various parts of our application and how we can use them to orchestrate a bigger business process.
Data and Bounded Contexts by Volodymyr BynoPivorak MeetUp
Just a small talk about data segregation/modularity from the DDD perspective. It might be interesting for engineers that have to deal with the huge projects. Especially ones that are looking forward to visiting DDD workshop.
Successful Remote Development by Alex RozumiiPivorak MeetUp
More about his talk :
"You've most likely already heard something about remote work. While the concept is not that old, it's a trend that many well-known brands are implementing.
In this presentation, you'll learn the essentials and seldom thought of pitfalls about remote work. These are based on the speaker's experience working remotely for more than two years. Many of these lessons were gained while working at Toptal, a company whose whole business model is built around remote work."
Eugene Pirogov talks about “Origins of Elixir” during #pivorak Lviv Ruby MeetUp 2016
Details:
“For the past 6 years I've been programming in Ruby. Began shifting from Ruby to Elixir during a sabbatical. Started doing programming exercises in Elixir as well as contributing to Elixir language and variety of small libraries in the ecosystem. I'm a strong believer that Elixir, being backed by immensely powerful, robust and battle-tested Erlang VM will take over the world of web development.” - that’s what Eugene says.
The talk will be about solving CSS issues in big projects by adopting Functional CSS methodology.
You will learn how to take best ideas from Functional Programming, and apply them to your CSS codebase. This means side-effects are limited or nonexistent, already created classes can't be overridden because they are immutable and they are trying to be as "pure" as it's possible to achieve in CSS.
Multi language FBP with Flowex by Anton Mishchuk Pivorak MeetUp
The talk is about Flow-Based programming (FBP) using Flowex library built on top of Elixir GenStage feature.
You will find out about Flowex Railway-FBP design approach, about its abstractions, and the way to easily create pipelines of independent components.
Our speaker Anton also demonstrates how one can use Ruby, Python, and, in general, any other programming language inside Flowex pipes and therefore create reusable components with language-specific functionality.
About the speaker:
Anton Mishchuk is an experienced Ruby developer with more than 6 years in business). Now he’s working with Matic Insurance.
For the last 3 years his main addiction has been Elixir: “I’m happy with actors model of concurrency and functional programming. I have a couple of open-source projects written in Elixir - BDD testing library - ESpec and Flowex.”

CryptoParty: Introduction by Olexii MarkovetsPivorak MeetUp
Olexii, what’s your topic exactly about?
This is about CryptoParty: decentralized movement with the goal to pass on knowledge about protecting yourself in the digital space.
I will try to give general overview on what CryptoParty is, why would anyone care about privacy on the internet and what is common topics covered during CryptoParty.
For whom will it be a useful topic?
Anyone, actually anyone, no technical background is required.
About Olexii:
"I’m a programmer. I write code. Mostly I’m involved in Linux system programming. I like to think that I’m quite good in C++. Currently, privacy and anonymity on the internet is one of the topics on which I spend my spare time."
Olexii introduced some of us to CryptoParty last Summer (the first time in Ukraine, woah!), but it’s time to share the ideas with the wider audience.
How to make first million by 30 (or not, but tryin') - by Marek PiaseckiPivorak MeetUp
This time Marek won’t be talking about what’s wrong with frameworks, because you can read it in his blog - http://bit.ly/2jSN0z4.
But about progressing career - strategy, negotiations, self development. And it will be his own story.
It should be interesting for anyone who cares about career/money - not only Ruby Devs.
Marek is from Poland, but now he works as a contractor in Rome for International Fund for Agricultural Development (IFAD) - which is United Nations agency. I’m using Rails of course :)” - he says.
Marek was our Lightning Talker last April about anti-frameworks. Please, check out his talk here emoji unicode: 1f3a5emoji unicode: 1f449 https://youtu.be/QsAArlQnktI
Oleksandr gives a Lightning talk about GIS integration: Storing and displaying geospatial data using OpenGeo Suite.
I would tell about:
- GIS itself;
- open source software called OpenGeo Suite;
- Geo spatial data representation in Geoserver (shapefiles and postgresql databases with postgis extension);
- Scalable data import using rest api.
Finally i would present the way to serve stored data using Open Layers.
This topic might be useful for Ruby Devs, GIS enthusiasts that are looking for free and powerful tools and other Backend devs.
Unikernels - Keep It Simple to the Bare MetalPivorak MeetUp
In this presentation Tomek Kalinowski introduces the Audience to the idea of “Library Operating System” and its modern extension - The Unikernel.
In short unikernel is another way of packaging and deploying code in which everything, including operating system, is tailored to serve your code’s single purpose (like displaying random cat pictures).
We'll try to answer the questions:
- Why and when it can be useful?
- Is this reusable? Interoperable?
- How we can leverage virtualization?
And last, but not least, is this the answer for inevitable coming of our Lord and Savior FPGA?
Modern design is crucial in today's digital environment, and this is especially true for SharePoint intranets. The design of these digital hubs is critical to user engagement and productivity enhancement. They are the cornerstone of internal collaboration and interaction within enterprises.
TROUBLESHOOTING 9 TYPES OF OUTOFMEMORYERRORTier1 app
Even though at surface level ‘java.lang.OutOfMemoryError’ appears as one single error; underlyingly there are 9 types of OutOfMemoryError. Each type of OutOfMemoryError has different causes, diagnosis approaches and solutions. This session equips you with the knowledge, tools, and techniques needed to troubleshoot and conquer OutOfMemoryError in all its forms, ensuring smoother, more efficient Java applications.
Code reviews are vital for ensuring good code quality. They serve as one of our last lines of defense against bugs and subpar code reaching production.
Yet, they often turn into annoying tasks riddled with frustration, hostility, unclear feedback and lack of standards. How can we improve this crucial process?
In this session we will cover:
- The Art of Effective Code Reviews
- Streamlining the Review Process
- Elevating Reviews with Automated Tools
By the end of this presentation, you'll have the knowledge on how to organize and improve your code review proces
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Advanced Flow Concepts Every Developer Should KnowPeter Caitens
Tim Combridge from Sensible Giraffe and Salesforce Ben presents some important tips that all developers should know when dealing with Flows in Salesforce.
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
Exploring Innovations in Data Repository Solutions - Insights from the U.S. G...Globus
The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.

5. What is Rails?
• Ruby on Rails is an extremely productive web
application framework written in Ruby by
David Heinemeier Hansson in 2005.
• 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.
• No compilation phase required.
• Full-stack framework.
• Convention over Configuration
6. Full-stack framework.
•Includes everything needed to create a database-driven
web application, using the Model-View-Controller
pattern.

built to work seamlessly together with less code.
•Requires fewer lines of code than other frameworks.
8. Convention over Configuration
•Rails shuns configuration files in favor of conventions,
reflection, and dynamic runtime extensions.
•Your application code and your running database
already contain everything that Rails needs to know!
12. App directory structure
• app - main app directory
• bin - rails needed scripts
• config - configurations for environment, routes,
etc.
• db - schema.db, migrations
• lib - folder for code not included in main app (like
your own gems)
• log - log files
• public - assets for public access, 404 page etc.
• test(spec) - test files
• tmp - place for temporary files
• vendor -folder used for third-party libraries.
13. Gemfile
A Gemfile is a file
which is used for
describing gem
dependencies for
Ruby programs.
What is Gemfile?
15. Development Workflow
• Use the rails command to create the basic skeleton of the application.
• Create a database on the MySQL server to hold your data.
• Configure the application to know where your database is located and the login
credentials for it.
• Create Rails Active Records (Models), because they are the business objects
you'll be working with in your controllers.
• Generate Migrations that simplify the creating and maintaining of database tables
and columns.
• Write Controller Code to put a life in your application.
• Create Views to present your data through User Interface. us start with creating
our library application.
17. ActiveRecord
• Rails Active Record is the Object/Relational Mapping (ORM) layer
supplied with Rails.
• Each Active Record object has CRUD methods for database access
18. Associations
Active Record supports three types of
associations:
• One-to-one (has_one);
• One-to-many (has_many);
• Many-to-many (has_and_belongs_to_many,
polymorphic);
19. Model in DB
• Each entity (such as book) gets a table in the database named after
it, but in the plural (books).
• Each such entity-matching table has a field called id, which contains a
unique integer for each record inserted into the table.
• Given entity x and entity y, if entity y belongs to entity x, then table y
has a field called x_id.
• The bulk of the fields in any table store the values for that entity's
simple properties (anything that's a number or a string).
20. Validations
The implementation of validations is done in a
Rails model. The data you are entering into the
database is defined in the actual Rails model, so it
only makes sense to define what valid data
entails in the same location. Also you can provide
custom validations.
21. Migrations
Rails Migration allows you to use Ruby to define
changes to your database schema, making it possible
to use a version control system to keep things
synchronized with the actual code.
23. Routes
The routing module
provides URL rewriting in
native Ruby. It's a way to
redirect incoming
requests to controllers
and actions. Best of all,
Rails' Routing works with
any web server.
Routes are defined in:
app/config/routes.rb
24. `
Rails named routes starts
with HTTP verb. It
supports all the verbs
such as: GET, POST,
PUTPATCH, DELETE.
25. Routes
Also rails have a special
route for root path.
You can match any url
to any action.
28. Controller
The Rails controller is the
logical center of your
application. It coordinates the
interaction between the user,
the views, and the model.
31. Strong params
It provides an interface for
protecting attributes from end-
user assignment. This makes
Action Controller parameters
forbidden to be used in Active
Model mass assignment until
they have been whitelisted.
32. Action View
In Rails, web requests are handled by Action Controller and Action View. Typically,
Action Controller is concerned with communicating with the database and performing
CRUD actions where necessary. Action View is then responsible for compiling the
response.
Action View templates are written using embedded Ruby in tags mingled with HTML.
34. Helpers
The Rails framework provides a
large number of helpers for
working with assets, dates,
forms, numbers and model
objects, to name a few. These
helpers are available to all
templates by default.
In addition to using the
standard template helpers
provided, creating custom
helpers to extract complicated
logic or reusable functionality
is strongly encouraged.
41. Homework
Write a simple web app which allows you to create an
event(bbq, pizza-day, or etc.). Add credentials to it (place, date,
etc…). Add two roles, admin, and attendee. Admin can add an
event, delete event, add a description, edit an event, add
comments to the event. The attendee can join an event, can
leave an event, can add comments to the event. You will need to
cover it by your preferred test framework and deploy to Heroku.
