The Rails View

"Break free from tangles of logic and markup in your views, and implement your user interface in Rails cleanly and maintainably. Build up solid, sustainable layouts with HTML5. Then learn to manage your forms and keep your markup clean. Learn when (and when not) to use Presenters, and how to tame HTML emails. Master the asset pipeline introduced in Rails 3.1 as you use Sass and CoffeeScript to create easy-to-manage code for enjoyable user interfaces"--P. [4] of cover.

Teaches Rails by guiding you through the development of three example applications of increasing sophistication. The tutorial's examples focus on the general principles of web development needed for virtually any kind of website. The updates to this edition include full compatibility with Rails 5, a division of the largest chapters into more manageable units, and a number of new exercises interspersed in each chapter for reinforcement of the material. This guide provides integrated tutorials not only for Rails, but also for the Ruby, HTML, CSS, and SQL skills you need when developing web applications. Hartl explains how each new technique solves a real-world problem, and then he demonstrates it with bite-sized code. --From publisher description.

The Complete Guide to Avoiding and Fixing Common Rails 3 Code and Design Problems As developers worldwide have adopted the powerful Ruby on Rails web framework, many have fallen victim to common mistakes that reduce code quality, performance, reliability, stability, scalability, and maintainability. RailsTM AntiPatterns identifies these widespread Rails code and design problems, explains why they’re bad and why they happen—and shows exactly what to do instead. The book is organized into concise, modular chapters—each outlines a single common AntiPattern and offers detailed, cookbook-style code solutions that were previously difficult or impossible to find. Leading Rails developers Chad Pytel and Tammer Saleh also offer specific guidance for refactoring existing bad code or design to reflect sound object-oriented principles and established Rails best practices. With their help, developers, architects, and testers can dramatically improve new and existing applications, avoid future problems, and establish superior Rails coding standards throughout their organizations. This book will help you understand, avoid, and solve problems with Model layer code, from general object-oriented programming violations to complex SQL and excessive redundancy Domain modeling, including schema and database issues such as normalization and serialization View layer tools and conventions Controller-layer code, including RESTful code Service-related APIs, including timeouts, exceptions, backgrounding, and response codes Third-party code, including plug-ins and gems Testing, from test suites to test-driven development processes Scaling and deployment Database issues, including migrations and validations System design for “graceful degradation” in the real world

“Ruby on Rails™ Tutorial by Michael Hartl has become a must-read for developers learning how to build Rails apps.” —Peter Cooper, Editor of Ruby Inside Using Rails, developers can build web applications of exceptional elegance and power. Although its remarkable capabilities have made Ruby on Rails one of the world’s most popular web development frameworks, it can be challenging to learn and use. Ruby on Rails™ Tutorial, Second Edition, is the solution. Best-selling author and leading Rails developer Michael Hartl teaches Rails by guiding you through the development of your own complete sample application using the latest techniques in Rails web development. The updates to this edition include all-new site design using Twitter’s Bootstrap; coverage of the new asset pipeline, including Sprockets and Sass; behavior-driven development (BDD) with Capybara and RSpec; better automated testing with Guard and Spork; roll your own authentication with has_secure_password; and an introduction to Gherkin and Cucumber. You’ll find integrated tutorials not only for Rails, but also for the essential Ruby, HTML, CSS, JavaScript, and SQL skills you’ll need when developing web applications. Hartl explains how each new technique solves a real-world problem, and he demonstrates this with bite-sized code that’s simple enough to understand, yet novel enough to be useful. Whatever your previous web development experience, this book will guide you to true Rails mastery. This book will help you Install and set up your Rails development environment Go beyond generated code to truly understand how to build Rails applications from scratch Learn test-driven development (TDD) with RSpec Effectively use the Model-View-Controller (MVC) pattern Structure applications using the REST architecture Build static pages and transform them into dynamic ones Master the Ruby programming skills all Rails developers need Define high-quality site layouts and data models Implement registration and authentication systems, including validation and secure passwords Update, display, and delete users Add social features and microblogging, including an introduction to Ajax Record version changes with Git and share code at GitHub Simplify application deployment with Heroku

Transition from the traditional Rails model-view-controller trio to an abstraction model and let your application codebase evolve with synchronized components, boosting flexibility and maintainability. Purchase of the print or Kindle book includes a free PDF eBook through the link provided within Key Features Understand Rails' architectural patterns along with its advantages and disadvantages Organize business logic in Rails apps when the default approach is insufficient Introduce new abstractions to address design problems Book DescriptionRuby on Rails is an open-source framework for building web applications from scratch while focusing on productivity, leveraging the power of the convention-over-configuration principle, and the well-defined model-view-controller pattern, assisting the developers in building useful features. However, this initial simplicity often leads to uncontrollable complexity turning the well-structured codebase into a hardly maintainable mess. This book aims to help you keep the code maintainable while working on a Rails application. You’ll start by exploring the framework capabilities and principles, allowing you to reap the full potential of Rails. Then, you’ll tackle many common design problems by discovering useful patterns and abstraction layers. By implementing abstraction and dividing the application into manageable modules, you’ll be able to concentrate on specific parts of the app development without getting overwhelmed by the entire codebase. This strategy also encourages code reuse, simplifying the process of adding new features and enhancing the application's capabilities. Additionally, you’ll explore further steps in scaling Rails codebase, such as service extractions. By the end of this book, you’ll be a code design specialist with a deep understanding of the Rails framework principles.What you will learn Discover Rails' core components and its request/response cycle Understand Rails' convention-over-configuration principle and its impact on development Explore patterns for flexibility, extensibility, and testability in Rails Identify and address Rails' anti-patterns for cleaner code Implement design patterns for handling bloated models and messy views Expand from mailers to multi-channel notification deliveries Explore different authorization models and layers Use a class-based approach to configuration in Rails Who this book is for This book is for Rails application developers facing challenges in managing the growing complexity of their projects. It offers practical strategies for maintaining code readability and manageability, providing valuable guidance for developers at all levels. Whether you've recently launched your first Rails minimum viable product or are struggling to progress with a sizable monolithic application, this book is here to help. A deep understanding of core Rails principles is a must. Some experience in building web applications using the Rails framework will enhance your comprehension and application of the concepts presented in the book.
