Multi tenant/lang application with Ruby on Rails
•
1 like•1,699 views
This document describes how to build a multi-tenant Rails application that can handle multiple domains and languages. It introduces a Website model to store domain and language configuration and a WebsiteSwitcher middleware that sets the current website based on the domain. The middleware initializes a WebsiteSwitcher using the request host, finds the corresponding Website, and sets it as the current website along with its language before the request is passed to the application. This allows a single Rails app to serve different content and languages depending on the domain or host.

Connect front end to back end using SignalR and Messaging
If you've ever worked on a message-based system, at some point you have probably asked the question: How can I connect my asynchronous back-end to the front-end?
This webinar is focused on answering this non-trivial question, outlining scenarios and solutions available in our toolbox to easily make the back-end talk to the front-end in a way that is both robust and scalable.
The cornerstone of the system we will study in this webinar is SignalR, a library that facilitates adding bi-directional communication between the server and the browser over the WebSocket protocol. We will also see how NServiceBus messaging framework can be used in combination with SignalR.
When the basic scenario is up and running, we will venture into making the system scale to many server instances. We will introduce the concept of a backplane that forwards messages to all server instances so that a client connected to one instance can receive messages sent from another one. We will implement the SignalR backplane using Redis, a popular open source in-memory key-value store.
Learn how to:
* Connect back-end systems to the frontend
* Use correlation, and why it's important
* Use SignalR with message-based systems
* Use SignalR with NServiceBus
* Achieve real time notifications in a JavaScript SPA
* Provide user feedback in web applications

Velocity EU 2014 — Offline-first web apps
The upcoming HTML5 feature known as Service Worker is set to turn the web on its head, enabling websites to run without an internet connection and to load quickly even when the connection is bad.
But with that evolutionary step, web applications need to become more complex, and to handle the fact that their source code may remain on a device for much longer than a single session. Without the safety net of starting fresh every time the user hits a link, considerations such as memory management, data consistency, encapsulation and backwards compatibility now come into play. Front-end developers are suddenly fully-fledged software engineers! The web page is our app platform, and the browser our runtime.

Michelle Sanver "Using the Workflow component for e-commerce"
We got the task to make an order API, from open order, to delivered, with payments in between and after. So there are naturally a lot of states, and a lot of transitions where we needed to calculate the prices correctly and handle credit card transfers. Keeping track of all of this, and when we need to do what, ensuring that an order is always up to date, and that it has the data it needs, and that we send good error messages when a user can not do an action, was a challenge for us until we discovered the workflow component.
This is a real happy use case story where I will show you how we did this, and how much more straightforward it was for us to build an otherwise complex system using the workflow component.
Beyond MVC: from Model to Domain
Given at TrueNorthPHP 2014:
"MVC presents a great way to divide responsibilities in your application but it offers no help in building the most critical part: the model or domain. This talk will introduce ways that can help you to encapsulate the richness of your domain. We'll look at Action Domain Response as a new way of thinking about the concepts presented in MVC before examining Hexagonal Architecture, allowing you to easily reuse your domain across multiple delivery mechanisms. We'll then finish with an introduction to Domain Driven Design, a technique that allows you to closely align your domain with the business problems it is solving while helping keep things well designed and easily maintainable. By the end of this talk you should have the knowledge needed to begin modelling your domains more powerfully while keeping them aligned to the real world problems they solve."

Organize your assets with Rails
Slides of my talk at Paris.rb on june, 5th 2015. This talk is about assets organization in a Rails project and how you can see your CSS as components.
Speed your Rails app creation with templates
The document discusses using Ruby templates to speed up Ruby on Rails application creation. It provides an example of a simple Ruby file template that adds common gems, creates initializers, sets the default locale, runs generators, and more. The template can be used with the 'rails new' command to automatically configure a new Rails project.
Dependency sorting in Ruby with TSort
The document discusses using topological sorting with TSort to determine the order of tasks that have dependencies on each other. It provides an example class called TaskList that includes TSort and allows adding tasks with their dependencies. By implementing the tsort_each_node and tsort_each_child methods, it enables topological sorting of the tasks to determine the optimal order to complete them while respecting the dependencies.
How Unidecoder Transliterates UTF-8 to ASCII
Slides of my talk at Paris.rb on 2014-11-07. How does UTF-8 work? How to leverage it to convert chinese, russian or any non-ASCII character to ASCII? Here is what the Unidecoder gem does.
Get Slim!
The document summarizes two templating languages used in Ruby on Rails: Slim and Haml. Slim renders templates faster than ERB and Haml, uses less symbols like %, and handles spacing in a more explicit opt-in way. It also allows nesting elements and conditional logic in a more readable way. Slim is a recommended alternative to ERB and Haml for writing DSL-style template code in Ruby.
Fake your files - MemFs
The document discusses different approaches for testing file manipulation in Ruby without actually creating or modifying files on disk. It begins by showing some simple tests that create a file, then explores issues that can arise like read-only file systems. It introduces the FakeFS and MemFS gems for faking file system operations in tests. FakeFS overwrites core classes so options may be ignored, while MemFS avoids this by only overriding low-level classes. In the end, it recommends MemFS for faking file system operations during tests to avoid unintended behaviors and get accurate test results.
Rails is like Burger King
The document compares Rails to Burger King by listing various components that make up their architectures. It lists clients, stuff/steaks, cooks, boxes, waiters, and questions as common elements that represent the data, model, controller, and view layers in Rails and the customers, food, kitchen staff, packaging, servers, and inquiries in a Burger King restaurant.
REST with Her (and let Her take care of the REST)
The document discusses Her, a Ruby gem that provides a simple and lightweight way to interact with REST APIs. It allows defining models that map to API resources and provides basic CRUD and custom methods that map to HTTP requests. Her is built on top of Faraday and integrates Faraday's middleware functionality. This allows adding caching, authentication, and other common middleware. The document provides examples of defining models, calling CRUD and custom methods, and configuring Faraday middleware via Her.
Ruby and DCI
This document discusses issues with using the Data Context Interaction (DCI) pattern in Ruby. It provides examples of implementing DCI by extending classes with modules versus using delegation. Performance benchmarks show extending classes is slower due to Ruby's method cache being invalidated. Delegation is presented as an alternative that avoids this performance penalty. The document concludes by inviting questions about these DCI implementation approaches in Ruby.
Cells
The document discusses using Cells to share a widget like a shopping cart between pages on a Rails site. It describes the traditional solution of setting the cart in the application controller before_filter. It then explains how Cells provides a better organized solution by rendering the cart cell and defining the display logic in the cell class. Some advantages of Cells include separation of responsibilities and cleaner code organization. It also provides examples of defining additional cell actions and caching capabilities.
Mustdown
This document demonstrates the Mustdown gem, which allows templates containing Mustache tags to be rendered with objects and output as HTML or Markdown. Mustdown supports rendering templates using Mustache, Markdown, ERB templates, and I18n translations. It also allows configuration of Markdown rendering and caching of compiled templates for better performance.
Vos Regexps sont fausses !
The document discusses regular expressions (regex) for validating email addresses. It notes that the typical regex using ^ and $ anchors only match the beginning and end of lines, not strings. It recommends using \A and \Z anchors instead to match the true beginning and end of strings. An updated regex for validating emails using the \A and \Z anchors is provided.
Ariane
This document discusses Ariane, a breadcrumbs gem for Rails applications. It provides flexibility and facilitates both usage and participation. Ariane allows adding breadcrumbs in controllers and views, rendering them with default or custom renderers, and configuring options like the divider and renderer parameters. Future goals include dynamic breadcrumbs and syntactic sugar. Resources include the Github repository and the author's Twitter account.
Pourquoi Ruby on Rails ça déchire ?
This document provides an overview of Ruby on Rails, including its core components like MVC, Active Record, routing, views, helpers, and generators. It explains how Rails uses conventions to simplify development tasks. It also discusses how Rails is extensible through gems and lists some well-known companies that use Rails in production, like Twitter, GitHub, and Shopify. Additional resources for learning Rails are provided at the end.
Commander
Commander is a Ruby library that provides tools for building command line interfaces. It allows defining commands, options, and receiving input. Some key features include:
- Defining commands with descriptions, syntax, and actions
- Support for command options like prefixes, suffixes, and other parameters
- Interactive input using Highline for questions, passwords, choices
- Customizable with features like progress bars, speech synthesis, and table output
The library provides an easy way to build full-featured command line applications and interfaces in Ruby.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
