Overview of this book

Anyone striving to become an expert Ruby programmer needs to be able to write maintainable applications. Polished Ruby Programming will help you get better at designing scalable and robust Ruby programs, so that no matter how big the codebase grows, maintaining it will be a breeze. This book takes you on a journey through implementation approaches for many common programming situations, the trade-offs inherent in each approach, and why you may choose to use different approaches in different situations. You'll start by refreshing Ruby fundamentals, such as correctly using core classes, class and method design, variable usage, error handling, and code formatting. Then you'll move on to higher-level programming principles, such as library design, use of metaprogramming and domain-specific languages, and refactoring. Finally, you'll learn principles specific to web application development, such as how to choose a database and web framework, and how to use advanced security features. By the end of this Ruby programming book, you’ll be a well rounded web developer with a deep understanding of Ruby. While most code examples and principles discussed in the book apply to all Ruby versions, some examples and principles are specific to Ruby 3.0, the latest release at the time of publication.

Designing URL paths

Once you've selected a web framework, the next important decision to make is how to design the URL path structure for your application. Now, you might be wondering, why does a URL path structure matter for my application, as long as requests are handled as I want them to be handled? Well, how you structure URL paths can affect how your application is designed.

Let's say you have a discussion forum application that deals with forums, topics, and posts. Each forum, such as Ruby Programming Books, can have topics such as Which is the Best Ruby Programming Book?, and each topic can contain many posts from the members of the forum with their thoughts on that topic. There are many possible ways to design a URL path structure for such a forum application.

You could call one approach the flat approach, where each separate type has its own top-level path. For example, you could have the following three URL paths for the forum application:
