The free HTML version of the book is available at http: Do you really want to learn programming but have no skill?
Are you a system administrator who wants to learn Puppet or Chef? Are you a designer who wants to build your own websites? Then you should read this book. It assumes absolutely no prior programming knowledge and will guide you carefully and slowly through the learning process.
When you are done with this book you will have the skill to move on to other books about Ruby and be ready to understand them. You can visit the companion site to the book at http: Computers are everywhere, on every desk, in your iPod, cell phone, and PDA.
To live well in the 21st century, you need to know how to make computers do things. And to really make computers do what you want, you have to learn to program. Now everyone can learn to write programs for themselves—-no previous experience is necessary. Chris takes a thorough, but light-hearted approach that teaches you how to program with a minimum of fuss or bother. For this new edition of the best-selling Learn to Program , Chris Pine has taken a good thing and made it even better.
First, he used the feedback from hundreds of reader e-mails to update the content and make it even clearer. Second, he updated the examples in the book to use the latest stable version of Ruby, and also to use code that looks more like real-world Ruby code, so that people who have just learned to program will be more familiar with common Ruby techniques.
Not only does the Second Edition now include answers to all of the exercises, it includes them twice.
Cooper, Peter Beginning Ruby: Based on the bestselling first edition, Beginning Ruby: From Novice to Professional, Second Edition is the leading guide for every type of reader who wants to learn Ruby from the ground up. The new edition of this book provides the same excellent introduction to Ruby as the first edition plus updates for the newest version of Ruby, including the addition of the Sinatra and Ramaze web application frameworks and a chapter on GUI development so developers can take advantage of these new trends.
Beginning Ruby starts by explaining the principles behind object-oriented programming and within a few chapters builds toward creating a full Ruby application. Beginning programmers, programmers new to Ruby, and web developers interested in knowing the foundations of the language. Starting with the basics strings, numbers, objects and methods it quickly moves on to explain all you need to know to create your own class hierarchies, use arrays, hashes, iterators, modules, mixins and much more besides….

Knowing what gems to use, and why, is an important aspect of learning Rails. Book Two will show you how to build a web application using some of the most commonly used gems. Strictly speak- ing, Git and GitHub are not part of Rails they are tools that can be used on any development project.
And there are several other version control systems that are used in open source development. Tester Perspective Finally, we can consider a Rails application from the perspective of a tester. Before Rails, au- tomated testing was rarely part of web development. A web application would be tested by users and maybe a QA team. If automated tests were used, the tests were often written after the web application was largely complete.
With TDD, tests are often written before any imple- mentation coding. First, the devel- oper will give thought to what needs to be accomplished and think through alternatives and edge cases. Second, the developer will have complete test cov- erage for the project. TDD is seen as a necessary skill of an experienced Rails developer. Book Two will introduce you to the basic concepts of test-driven development and show you how to write simple tests.
You understand Rails is a software library plus an API, as well as a community of developers. Full Stack A technology stack is a set of technologies or software libraries that are used to develop an application or deliver web pages. Often we consider a stack as layers added to the operating system. For a web application, we need a web server, a database, a programming language, and perhaps additional software libraries.
In , Rails was not well known and Zuckerberg chose to implement his ideas using PHP without any additional web application software library. For this tutorial, your application stack will be: Rails Stacks Sometimes when we talk about a stack, we only care about part of a larger stack.
For example, a Rails stack includes the gems we choose to add features to a website or make development easier. Sometimes the choice of components is driven by the requirements of an ap- plication. At other times, the stack is a matter of personal preference. The company 37signals, where the creator of Rails works, uses this Rails stack: Another stack is more popular among Rails developers: The Rails stack can vary, and it is part of a larger stack that includes an operating system, web server, and database.
The debates are a source of much innovation and improvement for the Rails framework. In the end, the power of the crowd prevails; usually the best components in the Rails stack are the most popular. In this tutorial, we stick to solid ground where there is no debate. Chapter 5 Why Rails? Before you start building an application with Rails, it may help to know why developers like using Rails.
This chapter looks at the history of Rails, its orga- nizing principles, and the reasons for its popularity. Why Ruby? By most measures of programming language popularity, Ruby ranks among the top ten, though usually as tenth or so in popularity, and largely due to the popularity of Rails. Like Java or the C language, Ruby is a general-purpose programming language, though it is best known for its use in web programming.
He tried Ruby and was excited about the ease of use he calls it pleasure he found in the Ruby language. Ruby is a modern language that makes it easy to use high-level abstractions such as metaprogramming. RubyGems pro- vides a simple system to install gems. Anyone can upload a gem to the central RubyGems website, making the gem immediately available for installation by anyone.
And it is where you will obtain all the gems that help you build complex websites. Ruby has several disadvantages at least when programmers want to argue. Rails is popular and widely used because its conventions are pervasive and astute.
Any web application has complex requirements that include basic func- tions such as generating HTML, processing form submissions, or accessing a database.
Without a web application development framework, a programmer has a mammoth task to implement all the required infrastructure. Even with a web application development framework, a programmer can take an idiosyn- cratic approach, building something that no one else can easily take apart and understand. The singular virtue of Rails is that Heinemeier Hansson, and the core team that joined him, decided that there is one best way to implement much of the infrastructure required by a web application.
Many of the imple- mentation decisions appear arbitrary. The advantage of establishing conventions might seem obvious, but when Rails was released in , web development was dominated by PHP, which lent it- self to idiosyncratic code produced by solo webmasters, and Java frameworks such as Struts, which were often seen as burdened by an excess of structure. NET Framework, were in wide use but the frameworks were products controlled by the companies and built by small teams, which tended to restrict innovation.
Today PHP, Java frameworks, and. Understanding these principles will help you make sense of Rails or, at least, some of the debates on developer blogs.
Rails will also assume the table name is plural if the class name is singular. And, because other developers have learned the same conventions, it is easier to collaborate. In its simplest form, it is an admonition to avoid duplication.
The DRY principle can be extended to development processes as well as code. For example, manual testing is repetititive; automated testing is DRY. Software design patterns that introduce abstraction or indirection can make code more DRY; for example, by eliminating repetitive if-then logic. Code reuse is a fundamental technique in software development. Fortunately, by , the Rails core maintainers released the ActiveJob feature which implemented queueing.
Conventions or Magic? One of the joys of programming is knowing that everything that happens in an application is explained by the code. To avoid repetitive code, Rails often will offer default behavior that looks like magic because the underlying imple- mentation is hidden in the depths of the Rails code library.
You can implement a simple web application with only a few lines of custom code but you may wonder where all the behavior comes from. Chapter 6 Rails Challenges Rails is popular. Rails is powerful. We get discouraged. We complain. Sometimes we feel we should quit. This chapter is here to help with your resistance. Its purpose is to acknowledge that, yes, Rails can be difficult. Tens of thousands of people are successfully using Rails.
Perhaps some of them had more time to study or better access to men- tors, but these factors simply accelerate the speed of learning Rails. If you get discouraged, or think Rails is too hard, recognize that you are encountering your own resistance, not any genuine limitation. Take a break, set aside your learning materials, and come back when your natural curiosity and eagerness has returned.
These Rails challenges are obstacles, but other people overcame them. You can, too. A List of Challenges This list is incomplete. It is difficult to install Ruby. You are setting up a devel- opment environment and you need system software as well as Ruby. Sometimes you just have to look for someone to help. You can also use a hosted development environment, like Cloud9 or Nitrous. Rails is a nightmare on Windows. It seems the Rails community has a bias against Windows.
Rails is an open source project. Most open source develop- ers use Unix-based system tools. And expert Windows developers are seldom interested in porting Unix-based system tools to Windows.
So system utilities such as RVM are not available for Windows. And developers who create gems are seldom interested in spending time to solve the problems that arise when code has to be adapted for the idiosyncrasies of the Windows platform. This situation is not going to change, so you have to make a choice. Stay with Windows or get comfortable with Unix-based systems. Why do I have to learn Git? It is difficult.
Real software development requires version control and Git is the standard tool for Rails developers. You can skip all the parts of the book that mention Git. Why worry about versions?
Do I really need to learn about testing? Rails error reporting is cryptic. Actually, Rails error reporting is quite good. Stack traces are detailed and error messages are descriptive.
Beginners have a problem because the stack traces and error messages provide a technical analysis of a problem in terms that an experienced developer can understand. There is too much magic.
Default behavior often looks like magic because the underlying implementation is hid- den in the depths of the Rails code library.
If you like to know how things work, this can be frustrating. You really have only two choices when you encounter Rails magic. You can take time to dig into the source code. Even if you learn that the acronyms mean model-view-controller and represen- tational state transfer, MVC and REST are abstract concepts.
Understanding software architecture requires abstract reasoning, imagination, and experience, which takes time.
Book Two describes some of what you see. Yet even as you gain mastery of Rails, there will be aspects that remain unfamiliar.
There is too much to learn. Very true. But today there are many more high-quality tutorials and educational programs to accelerate your learning. As the knowledge domain has grown, so have the learning resources.
Get a foundation in the basics and then dive deep as a specialist in an area that appeals to you. Rails has been around since with major new versions released every two years.
There is no easy way to determine if the answer is out of date. A particular aspect of Rails may have changed—or not. It is difficult to know what gems to use. There are so many gems available for Rails. Some add useful features, like tagging or a mailing list API.
Some are basic, such as gems for a database or front-end framework. Even among basic gems, Rails offers choices. Which are best? Rails changes too often.
Each major release is well tested and relatively free of bugs. But new features or new approaches often require rewrites of older applications. Commercial software products often make a priority of keeping the API consistent over time. It is difficult to transition from tutorials to building real appli- cations.
Copying and pasting from tutorials is a good way to begin learning Rails. Focus on the basics that are described in this book. Start with user stories. Build pieces that you know how to do. Seek advice from peers or mentors. But you will pick up momentum. In particular, the Rails asset pipeline can be confusing for anyone who has done front-end development without Rails. Until recently in most countries, most Rails developers have been young men with an engineering background.
Lack of di- versity, and the cluelessness that accompanies it, is unfortunate in the Rails community. But many people are working to make the community more wel- coming and inclusive. Organizations such as Rails Girls and Railsbridge are creating more diversity in the community. These are some of the challenges you will face in learning and using Rails. Next, we will look at how to get help. No single document tells you how to use Rails. Book Two contains all the documenta- tion you need to build an application.
If you are in a classroom, or studying in a group, ask a peer to look at your problem. Most problems are caused by simple typos or formatting errors. Your classmate may see what you overlooked. The example application is updated more frequently than the published tutorial.
Thousands of beginners have successfully completed the book and, unless a gem has recently changed, you should have no problem. Getting Help With Rails What will you do when you get stuck?
Also be sure to compare answers to similar questions; the most popular answer is not always the correct answer to your particular problem. Instead, try Reddit for advice or recommendations. You can also visit the Quora question-and-answer site for topics devoted to Rails and Ruby. References Here are suggestions for the most important references. If you feel overwhelmed by all the links, remember that you can use Book Two to build the tutorial application without any additional resources.
The Rails Guides are an excellent reference if you want to check the correct syntax for Rails code. Cheatsheets Tobias Pfeiffer has created a useful Rails Beginner Cheat Sheet that provides a good overview of Rails syntax and commands.
These are extremely technical documents the only thing more technical is reading the source code itself. The documents offer very little help for be- ginners, as each class and method is considered in isolation, but there are times when checking the API documentation is the only way to know for certain how something works. I recommend Dash as a tool to look up classes, modules, and methods in Ruby and Rails.
Most large urban areas have meetups or user group meetings for Rails devel- opers. Try Meetup. The community of Rails developers is friendly and eager to help beginners. If you are near a Rails meetup, it is really worthwhile to connect to other developers for help and support.
Local user groups often sponsor hack nights or hackathons which can be evening or weekend collaborative coding sessions. Be- ginners are welcome. You can bring your own project which can be as simple as completing a tutorial. If you are a woman learning Rails, look for one of the free workshops from RailsBridge or Rails Girls.
Pair Programming Learning to code is challenging, especially if you do it alone. Look for opportunities to pair program. Learn more about pair programming on the site pairprogramwith. Pairing sessions often use: Pairing With a Mentor By far, the best way to learn is to have a mentor at your side as you undertake a project. You can try RailsMentors, a network of volunteer mentors offering free help. Market rates are expensive for a student, obviously, but if you are learning on the job or building an application for your own business, connecting online with a mentor might be a godsend.
AirPair connects developers for real-time help using video chat and screen shar- ing. Experts set their own rate and the site matches you according to your bud- get.
Knowing where to go for help is important; it is just as important to stay cur- rent. Staying Up-to-Date Rails changes frequently and its community is very active. Consequently, I urge you to stay up-to-date with news from the community. I urge you to sign up for two weekly email newsletters: Chapter 8 Plan Your Product Tutorials from other authors focus only on coding.
But Rails developers do more than code. Software development is a process that begins with planning and ends with analysis and review. Product Owner On your project, who is the product owner? The product owner is the advocate for the customer, making sure that the team creates value for the users.
If you are a solo operator, you are the one who will decide what features and functionality will be included in your application.
We call this managing scope and combating feature creep. In large organizations, a product owner may be a product manager or a project manager. A product owner usually is not a management executive though there will likely be an executive sponsor. User stories are a way to discuss and describe the requirements for a software application. The process of writing user stories helps a product owner identify all the features that are needed for an application.
User stories are often expressed in the following format: As a I want In order to Here is an example: Just use index cards or a Word document. Figure 8. A user story. Just like Rails provides a structure for building a web application, user stories provide a structure for organizing your product plan. Wireframes and Mockups Often, before writing user stories, a product owner will make rough sketches of various web pages.
Sketching is a phase where you try out ideas to clarify your vision for the application. Sketching can lead to a wireframe or a mockup. These terms are often used interchangeably but there are differences in mean- ing. It should not depict a proposed graphic design for a website, rather it should be a diagram of a web page, without color or graphics.
A mockup adds graphic design to a wireframe; including branding devices, color, and placeholder content. One of the most popular tools for creating wireframes is Balsamiq Mockups despite the name, it produces wireframes, not mockups.
There are dozens of others listed in the article Rails and Product Planning. Some people like a visual approach with wire- frames; others prefer words and narrative. Either approach will work; both are good. Graphic Design Very few people have skills as both a visual designer and a programmer.
The tools are different; graphic designers typically use Adobe Photoshop, though web-savvy designers often create designs directly in HTML and CSS, while developers write code.
If you are very lucky, you may work with someone who is a user experience UX designer or interaction designer IxD. Rails can be particularly challenging when it comes to integrating graphic de- sign with code. Few designers are comfortable with Ruby code mixed with HTML so you may end up doing integration yourself. Software Development Process Product planning is the initial phase of a larger software development process. Most hobbyist and student developers need no other approach.
When money or reputation is at stake, casual approaches to software develop- ment are risky. Compared to other forms of engineering, software development is peculiarly prone to failure. In fact, the Standish group reports that over 80 of projects are unsuccessful either because they are over budget, late, missing function, or a combination. If you are going to be held accountable for the success or failure of a project, you should learn more about software development methodologies.
Managers who can discuss software development methodologies are more likely to be concerned about the welfare of their team. Here are some software development methodologies you may hear about, with some notable characteristics: Behavior-Driven Development There is one prominent software development approach that is important for product planning.
BDD takes user stories and turns them into detailed scenarios that are accom- panied by tests. Most developers write scenarios using a simple text editor.
With automated tests, a product owner can determine if developers have suc- ceeded in implementing the required features.
This process is called accep- tance testing. This process is called regression testing. For an introductory book, BDD is an advanced topic. But on a project where money and reputation is at stake, BDD can be very important.
Feature and scenario. Are you taking care of everything that needs to be done? These questions are at the center of project management. The previous chapter on product planning showed how user stories can be used to break down an application into discrete features. User stories can be the basis for a list of tasks.
To-Do List You can track your tasks with a simple to-do list. Some entrepreneurs like the discipline of the GTD system Getting Things Done for personal productivity and time management. Our article on Rails and Project Management offers a list of popular to-do list applications, either for personal task management or team-oriented task management. Imagine putting a big whiteboard on your wall and creating columns for a series of to-do lists. The columns, called swimlanes, are labelled: Backlog, Ready, Coding, Testing, Done.
Each swimlane contains index cards that describe a user story or other task. See the article on Rails and Project Management for a list of kanban web ap- plications. Trello is particularly popular for task management.
Pivotal Tracker is the best known tool but there are many other agile tools. In most successful companies, Agile processes have replaced the much-maligned waterfall process that was once the norm for software development. Most Rails developers use Mac OS X or Linux because the underlying Unix operating system has long been the basis for open source programming.
For Windows users, I have to say, installing Rails on Windows is frustrating and painful. Even when you succeed in getting Rails to run on Windows, you will encounter gems you cannot install.
Cloud9 provides a hosted development environment. That means you set up an account and then access a remote computer from your web browser.
The Cloud9 service is free for ordinary use. There is no credit card required to set up an account. Any device that runs a web browser will give you access to Cloud9, including a tablet or smartphone, though you need a broadband con- nection, a sizable screen, and a keyboard to be productive. Get over this hump and everything else becomes easy.
The focus of this book is the background you need to understand Rails. You can get started now, with the links provided below, or you can wait until you have started reading Book Two. Cloud9 is free for small projects. If you have a fast broadband connection to the Internet, this is your best choice for developing Rails on Windows.
Us- ing a hosted development environment is unconventional but leading develop- ers do so and it may be the wave of the future. See this article for Cloud9 installation instructions: Other tutorials may suggest using RailsInstaller, but it will not provide an up-to-date version of Ruby or Rails.
Also, RVM does not run on Windows. Most people use a graphical user interface GUI to interact with their com- puters, tablets, or phones. This is what makes software programming look intimidating to learners. In fact, the terminal, or console, is a direct legacy of computers that were developed even earlier, in the s.
The terminal contin- ues to be the fundamental tool of software development. The Terminal The Terminal application or console gives us access to the Unix command line, or shell. Experienced developers often upgrade to the more powerful iTerm2 application but you can start with the installed Terminal application.
Look for the Terminal in the following places: If you have your computer in front of you, launch your terminal application now.
Try out the terminal application by entering a shell command. This is a longtime convention that indicates you should enter a command in the terminal application or console.
The Unix shell command whoami returns your username. If you are new to programming, using a text editor and the shell will seem primitive compared to the complexity and sophistication of Microsoft Word or Photoshop. We have to remember the commands we need or consult a cheatsheet because there are no graphical menus or tool- bars.
Yet with nothing more than a text editor and the command line interface, programmers have created everything that you use on your computer. If a Unix command is mysterious, you can look it up with Google. But a better approach is to use the website: Visit the website and enter ls -1p.
Many developers replace the standard Bash shell with the Z shell and Oh-my-zsh. A fancy prompt is helpful but requires some Unix skills to install. Everything you need to know is given at each step. If time is short, and you want to get started, you can jump into the Book Two tutorial without learning Unix commands.
