From the Publisher

From the Preface

Rails 1.0 was launched in December 2005. In the years since, it has gone from a comparatively unknown modern instrument to a profitable and steady basis with a big set of related libraries that others benchmark themselves towards.

The ebook you’re about to learn was there from the beginning, and it has developed with Rails. It started as a full reference to a small framework when on-line documentation was scarce and inconsistent. It’s now an introduction to the whole Rails ecosystem—one which leaves you with many tips to extra data that you could discover primarily based in your wants and needs.

This ebook didn’t simply evolve alongside with Rails: Rails developed with it. The content material on this ebook has been developed in session with the Rails core workforce. Not solely is the code you’ll see on this ebook examined towards every launch of Rails, however the converse can be true: Rails itself is examined towards the code on this ebook and gained’t be launched till these assessments move.

So learn this ebook with confidence that the situations not solely work but additionally describe how the Rails builders themselves really feel about how greatest to make use of Rails. We hope you get as a lot pleasure out of studying this ebook as we had in growing it.

This ebook covers Rails 6. While among the instructions you’ll be utilizing are new, the underlying improvement mannequin stays the identical. Even when new main options are added, resembling the flexibility to course of incoming emails with Action Mailbox, adjustments are evolutionary, not revolutionary.

(*6*)

Rails 6 launched two main new options and plenty of small enhancements. While Rails has at all times had robust help for sending emails, Rails’ skill to obtain emails has been pretty restricted till now. Action Mailbox introduces the idea of Mailboxes, that are controllers for processing incoming emails. You can use mailboxes to entry any a part of an incoming e mail, after which set off any workflow or logic, the identical as you’d in a traditional controller.

Rails 6 additionally provides seamless help for rich-text modifying & administration through Action Text. Action Text is an end-to-end integration of the Trix wealthy textual content editor to your Rails app utilizing Active Storage. With nearly no configuration, you may current a wealthy textual content editor to your customers, save that wealthy textual content, and render it again wherever you need, both as formatted textual content or plain textual content. This is a superb instance of how Rails takes what could possibly be a sophisticated set of disparate elements & brings them collectively so that they work everytime you want them to.

We’ve additionally up to date the setup directions to deal with Windows, macOS, and Linux. Since Cloud 9 was acquired by Amazon, it’s now a bit tougher to make use of as a approach to study Rails. To that finish, our setup directions for Linux now assume you might be doing this inside a digital machine, which ought to present a steady, repeatable setting during which to study Rails.

We’ll stroll you thru that setup when you want to study Rails that method.

Extra Q&A with the Authors

Why did you resolve to make a brand new version of this ebook?

The Rails Doctrine states the Rails favors progress over stability. Thus, it is essential to us that, as Rails progresses, so ought to this ebook. We need this ebook to to point out you not simply what you are able to do with Rails, however the state-of-the-art in how to try this.

It’s not a straightforward process. The first two variations of this ebook had been written by Dave Thomas. Sam Ruby took the lead on updating it for brand new variations of Rails after that, with David Copeland becoming a member of extra just lately.

All three of the co-authors have been wrangled and managed by first Susannah Pfalzer as editor and now by Adaobi Obi Tulton. We all actually suppose it is essential that this ebook stays as related as Rails.

What type of expertise would assist getting essentially the most out of this ebook?

Rails is nice in case you are a complete newbie, and the ebook permits a newbie with only a little bit of programming information to have the ability to get an app up and runnign simply. But, in case you are extra skilled with different methods of doing internet improvement, you may get much more out of the ebook since you’ll get extra out of Rails. You’ll expertise clear patterns and APIs for stuff you may be used to creating by hand on every venture, and it will really feel like a breath of recent air.

What do you hope readers take away from this ebook?

Two issues: first, that Rails is as related as ever to constructing trendy internet functions, and second, that Rails is accessible to everybody: from the least to most skilled builders, Rails will make them extra productive.

What’s your favourite a part of the ebook?

The chapter we added on Action Mailbox and Action Text is a superb instance of the facility of Rails. These are two new options that weren’t designed collectively however combine completely. Action Mailbox is a excessive stage approach to obtain emails into your Rails app, which was beforehand fairly tough to do and type of messy. Action Mailbox treats incoming emails the identical as an incoming internet request. We then use Action Text to permit responding to those emails in wealthy textual content. Action Text is a fancy JavaScript WYSIWYG widget that seamlessly integrates into Rails, and we use that to ship these wealthy textual content messages as formatted emails utilizing Action Mailer. Doing all this takes only a few traces of code. It’s a terrific demonstration of the facility Rails provides you.
