The document also provides guidance on creating plug-in render functions and using APEX APIs for assets, JavaScript, and AJAX callbacks.
This document discusses using Ruby testing techniques with C# and ASP.NET. It begins by explaining how the mindset and practices of Ruby testing, such as test-driven development (TDD) and behavior-driven development (BDD), can be applied. It then provides examples of writing Ruby-style tests for C# code using tools like RSpec and describes testing strategies like sharing examples across tests. The document advocates an outside-in approach of writing acceptance tests first before unit tests.

The document encourages sharing this information and visiting the Sunmitra website for more programming guides.
The document discusses various topics relating to building web applications with Ruby on Rails such as setting up authentication with Devise, working with assets using the asset pipeline, adding AJAX functionality using remote links and JavaScript responses, handling dependent associations to avoid orphan records, and creating custom view helpers like a gravatar image generator. It also briefly mentions deployment and provides code examples for integrating these techniques.
The Galen framework allows testing page layouts using Selenium and by verifying elements' positions relative to each other. It uses .gspec files to describe layouts with objects, groups, sections and tags. Verifications include checking widths, heights, alignments, text values, and relative positions using keywords like "near", "inside" and ranges. Results can be saved to HTML reports.
Ruby on Rails is a web application framework that follows the model-view-controller (MVC) pattern. It uses RESTful routing and conventions to map HTTP verbs like GET and POST to controller actions. Models define the data and behavior of an application, controllers handle and respond to user input, and views display the UI for users. Rails emphasizes conventions over configuration for productivity and includes features like caching, asset pipelining, and internationalization.
This document summarizes steps for creating a shopping cart in a Rails application. It covers generating a Cart model and LineItem model with relationships, using Rails sessions to associate the cart with each user, adding public and private methods, callbacks and validations, adding a button to add items to the cart, and modifying views and controllers. Testing is done to ensure functionality. Homework includes enhancing the functionality by adding a click handler, session counter, and conditional display.

A presentation given at the adaptTo() 2014 tech meetup on the topic of developing dynamic AEM components using concepts borrowed from the SPA philosophy.
Ruby on Rails is a web application framework that follows the model-view-controller (MVC) pattern and includes everything needed to build database-backed web applications using the Ruby programming language. It aims to make web development more productive by utilizing conventions that reduce the need for configuration and promote reuse of common tasks like connecting to databases. The framework provides models for interacting with the database, views for displaying the user interface, and controllers that handle and respond to user input by manipulating models and rendering views.
Ruby on Rails, often simply referred to as Rails, is an open-source web application framework written in Ruby. It follows the Model-View-Controller (MVC) architectural pattern, which separates an application into three interconnected components to promote code Ruby Rails Web Development organization and maintainability. Ruby on Rails has gained popularity for its focus on developer productivity and its convention-over-configuration philosophy, which significantly reduces the need for boilerplate code and configuration.
The document discusses several key technologies for developing Java web applications, including Java Servlet technology, WebWork framework, Spring framework, and Apache Maven build tool. It provides an overview of how each technology addresses common problems like stateless communication, business logic implementation, view generation, and data access overhead. Examples are given showing how WebWork and Spring can be used together with Maven to build a simple "Hello World" application that follows the MVC pattern and leverages dependency injection.
This document provides an overview of JavaScript including its history, key features, and comparisons to other languages. It also discusses important JavaScript concepts like objects, functions, events, and libraries like jQuery. Key topics covered include the window, document, location, and history objects, arrays, cookies, closures, inheritance, callbacks, and popular JavaScript libraries and frameworks.
As a software consultant, I get to see a lot of interesting code. In this particular instance a client was in the process of transforming their web application to a rich, interactive interface with the help of another company. The project kicked off using Backbone and things were great. Until they were not great. Pages starting getting more and more involved and blame started being thrown at the technology choice. A move to Ember.js ensued and the app was rewritten. But architecturally bad decisions don't hide long, and soon the rewrite was preforming even worse. That's when I stepped in, with the help of another consultant, to solve the performance issues once and for all. Our solution used Backbone.js and it was fast. This is that journey.

The document discusses setting up a Ruby on Rails web application. It explains how to install Ruby and Rails, configure the database, and generate models. The Rails directory structure is described, including the app, config, and db folders. Finally, it shows how to start the web server and create a basic Rails application.
Visual Studio "Orcas" will include major updates to support web development like a redesigned HTML editor, improved JavaScript support, and LINQ for querying data from various sources. It will also allow targeting multiple versions of the .NET framework from a single project. A beta release is expected in the summer with a focus on improved productivity and an easier upgrade process for existing developers.
Ruby on Rails is an open source web application framework that allows developers to create database-backed web applications quickly using conventions over configurations. Rails emphasizes less code and faster development through features like scaffolding that can generate basic CRUD functionality and views in minutes. Popular sites like Basecamp and 43 Things were built using Ruby on Rails by small teams in short periods of time due to Rails' conventions and built-in features for caching, validation, callbacks, and Ajax support.
