Rails Recipes 153

James Edward Gray II writes "If you have been swept up by the Rails craze or are even just a casual fan, you have probably been waiting for the terrific books to start rolling in. Some early entries, like Agile Web Development with Rails, were very solid but for me greatness arrived with Rails Recipes. For those who are not familiar with it, Rails is a full-stack web application framework, for quickly developing state-of-the-art web applications. Rails Recipes is the latest book on the subject from the Pragmatic Programmers." Read the rest of James's review.

summary A programming cookbook for all things Rails.


Let me tell you how I discovered Rails Recipes. At the Rails shop I work for, we needed a favorites system for our latest application. When I inherited the task of implementing favorites, I had heard just enough to guess that the new polymorphic associations feature of Rails might be just what I needed. Sadly, I had never even seen an example of their usage. Before leaving work that day, I checked the table of contents to make sure a recipe for what I needed was in there and and bought a combo pack, so the PDF would be waiting for me in the morning. The next day I built the entire favorites system and integrated it into our application with only the book as my guide. Total time for implementation, from cracking the book to a complete solution: just over three hours.

Needless to say, the book had completely won me over by that point. I started sneaking in recipe reads whenever I had a free moment or two and had literally devoured the book in no time. I completely expected it to show me cute AJAX tricks and handle common issues like login code and it certainly does these things. It also covers popular plugins, including Acts as Taggable and Acts as Versioned, as it should. What I didn't expect was for the book to include so many excellent low-flash coding recommendations as well. There are terrific recipes for DRYing up your code in various circumstances, building your own output forms for views, how to use models in migrations even if the files are long gone, integration testing as a DSL, routing methods, code generation, and a whole lot more.

The book has some surprising depth to the Rails insights it provides, not because the recipes are long but more because the topics are well chosen. Even the small "Snack Recipes" generally dive right to the heart of a commonly encountered matter. You get typical solutions and often some tips on how to customize the relevant Rails behaviors. For example, the book covers how to add inflections Rails can use in its singular/plural text transformations and how to tie your own form building classes right into the standard Rails helper methods.

I'm a long time Ruby user and I consider myself fairly knowledgeable with regard to the language, but this book taught me new tricks. I've read the Pickaxe, but for some reason IRb sessions never sunk in for me until this book showed the perfect example of using the on an ActiveRecord model to create a Ruby syntax database shell. The book even taught me some great YAML tricks for use in fixtures and configuration files.

Now I realize I've been gushing a little, so let me to balance it with at least some words of caution. First, this book assumes you know Rails. You will not learn Rails here. This should not be the first Rails book you read, though it does make an ideal second read and daily reference. I should also note that the recipe sections seem pretty arbitrary to me. I expected to find the login discussion in the "Big-Picture Recipes" section and the console tips in "Database Recipes", but they are located elsewhere. This might be a minor challenge for those who try to thumb straight to a recipe, but I've found searching the PDF makes this a non-issue. (The paper version of the book does have nice tabs drawn on the edge of pages to lead you to recipe types though, unrelated to the sections.) Finally, I should note that I've gone hunting in the book for about four work projects now, and found all but one. It didn't cover Acts as Threaded usage. Obviously it is impossible for a single book to answer all your questions about Rails, but a 75% ratio seems like a great start to me!

There are 70 recipes in this book split among user interface, database, controller, testing, big-picture, and email categories. I must stress again though how well these recipes pack in the tips. Don't be at all surprised if you learn an applicable view layer or even pure Ruby trick in a database recipe.

If you are a Rails user, I must recommend you pick up this title immediately. I really believe there is something in here for all.

    I typically dislike the "recipe" books available, as most of them seem to only touch about 10% of what I'm actually interested in. However, this book sounds better, maybe this is because the projects I'd be interested in using Ruby on Rails for are far simpler than most projects I undertake.

    Rails has been around for a while, and the books are all pretty good (bought 5, read 5, returned 5)... The only book really worth reading to any seasoned MVC or Morphic programmer is the Getting Started with Rails... The rest are really just rehash on MVC which is so dated we should all look carefully at why Rails is so special to the masses in the first place.

    Actually, I could hardly read your review, since it was so crammed with non-standard jargon (at least, from my perspective as a longtime C++/Java programmer). Lighten up on the Ruby-specific buzzwords, please! "how to use models in migrations", "integration testing as a DSL", "great YAML tricks for use in fixtures", huh???? It's nice that the book taught you how to do those things, whatever they are, but maybe a review should relate these things to more normal (non-Ruby) programmers' experiences in common language somehow.

    • Well, it *isn't* an appropriate first book on Rails. By the time you have an interest in or need for this book, you should know what those terms mean. Go through the exercise of building the "depot" application in the first few chapters of Agile Web Development With Rails, and this will all make perfect sense to you.

      I bought this book at the same time that I bought Programming Ruby and Agile Web Development with Rails. I paged through Recipies, and it was all Greek to me. I set it aside, having seen enough,

      To address your specific areas of confusion:
      • "How to use models in migrations" - Rails uses the "Model-View-Controller" structure for application architecture. It also offers scripts which automate the creation of new models: basically, you type "script/generate model modelname", and it drops in files for model code, unit tests, et cetera. Rails also offers a method for making updates to your application's database schema called "migrations." Every time you generate a new model, it will also create a dummy "migration" into which you can enter the code necessary to update your database, regardless of the specific type of database you're running (Informix, MySQL, Oracle, Postgres...).
      • "Integration testing as a DSL" - In Rails parlance, an "integration test" is a test which spans multiple models, controllers, and views. DSL, or "Domain Specific Langage," is a buzzword which basically means "a language specifically tailored to a certain task." It refers to the phenomenon some that Rails code, especially the integration test code, doesn't really scream "I am a Ruby program" to you - the method calls have evolved to the point where they look like a whole new language perfectly suited for a specific task. (That's the claim, anyhoo.)
      • "Great YAML tricks for use in fixtures - YAML stands for "YAML Ain't Markup Language [yaml.org]." It's a very simple way of representing data structures in text. Rails uses YAML for unit test fixtures: that is, your testing database can be populated with information from YAML files. Interestingly, the test fixtures can have Ruby code embedded directly in the YAML, enabling you to do stuff like iterate over hundreds of similar items. The embedded Ruby code is what makes the "great YAML tricks" possible.


      Hope this helps.

          • Acts as Versioned - see above, but allows you to have multi-versioned objects, instead of tags.
          • DRYing up your code - slang. DRY stands for "Don't Repeat Yourself." DRYing up your code, therefore, is making sure that you haven't duplicated code unnecessarily.
          • routing methods - methods that govern how a Rails application will choose a controller and method based on a URL. The "default route" in most Rails applications is "controller/method/id", meaning if I were to submit a GET request for "http://railsthingy.net/photos/view/101", the application would attempt to call the "view" method from the "photos" controller, with an argument "id=101".

Technically, I believe that acts_as_x uses mixins to work their magic: a mixin is Ruby's version of a Java "interface," basically a way to inherit functionality from multiple s

            • low-flash coding - The 'flash' is a small area that keeps things around until the next transaction. You should use it just to pass error messages from a failure of some type. Some programmers try to get tricky and use the flash as a psuedo session. Rails supports sessions fully and you should use the session for your needs. Getting tricky is usually a sign you don't really know what your doing in Rails.

      Most of those _are_ 'normal' terms.

      Models are a fundamental part of the MVC [wikipedia.org] design pattern (which originated in 1979 [ifi.uio.no], so it isn't exactly a rails buzzword!), integration testing [wikipedia.org] is part of general software testing, usually used in combination with unit testing, and YAML [wikipedia.org] is a markup language (sort of). They aren't Ruby or Rails specific.

      Don't assume you know all the 'normal' terms simply because you don't consider yourself a newby. You sound like one of those programers who think they know it all... bo

    Since I'm already familiar with Python and use it on a daily basis, my experience with Ruby has been pretty limited. This puts Ruby on Rails just out of my reach for a new project.
