![]() ![]() For example in Ruby on Rails, the convention states that a controller for a model object Book will be called BookController and all view pages relating to that controller will be kept in a folder called book.ĭRY is a principle that focuses on reducing information duplication by keeping any piece of knowledge in a system in only one place. Certain commonly used configurations (by convention and not by rule) are pre-set and the framework just works if you follow those conventions. Ruby on Rails follows two basic guiding principles-Convention over Configuration and Don't Repeat Yourself (DRY).Ĭonvention over Configuration is a programming design that favors following a certain set of programming conventions instead of configuring an application framework. Ruby on Rails is an open-source full stack web application framework built on Ruby. Ruby has a significant number of libraries that can be easily re-used through the gem packaging mechanism. ![]() Ruby is interpreted in real time, meaning that whatever is coded can be executed immediately without compilation. Ruby is designed for programmer productivity and can be used to quickly develop maintainable pieces of software. The external sources that a mashup uses are known as mashup APIs. Web mashups also usually mash up data and services that are available on the Internet-freely, commercially or through other partnership agreements. Web mashups are primarily web applications (though it is not a strict requirement). The word mashup itself comes from the world of hip-hop music, where two or more songs are mixed together to form a new song. The answer is that while older data and service aggregation technologies aggregate and integrate in a fashion, a true web mashup creates a completely different and new function out of the existing content and services, driving different purposes and objectives. Portals where different data and services were aggregated into portlets and displayed on the portal were popular during the dot-com era. Screen scraping was a commonly used older technology that takes content directly from another application's display. Data feeds such as RSS and ATOM feeds have been around for a while, making information available for anyone to re-use in another application. The idea of taking data and services from various places and making them available in a single application is not new. This book shows you how to write web mashups using Ruby on Rails-the new web application development framework. ![]() Welcome to the world of web mashups! A web mashup is a new type of web application that uses data and services from one or more external sources (usually from the Internet) to build entirely new and different web applications. This book covers: Google Maps API, Yahoo geocoding services, geocoding services, Geocoder.ca geocoding services,, Google Spreadsheet, EditGrid, Clickatell, Interfax, Amazon ECS, Sparklines, Facebook, Indeed, DayLife, Technorati, Futef, WebserviceX Currency Convertor, Weatherbug, Google Bases, Geonames, Flickr, Paypal, Google Calendar, Google Account Authentication, Google Data, and Google Spreadsheet Data. The book has seven real-world projects and each project is described in a methodical step-by-step way, showing how you can write a web mashup from the ground up. This book shows you how to write web mashups using Ruby on Rails— the new web application development framework.
