Releases Riding Rails. Rails 2. 0 is finally finished after about a year in the making. This is a fantastic release thats absolutely stuffed with great new features, loads of fixes, and an incredible amount of polish. Weve even taken a fair bit of cruft out to make the whole package more coherent and lean. What a milestone for Ruby on Rails as well. Using Puppet 4. x is recommended, which is available from the Puppet Labs repository. You may skip this and use Puppet 3. Ubuntu without a problem, however it.

Ive personally been working on this framework for about four and a half years and we have contributors whove been around for almost as long as well. Its really satisfying to see how far weve come in that period of time. That weve proven the initial hype worthy, that weve been able to stick with it and continue to push the envelope. Before jumping into the breakdown of features, Id just like to extend my deep gratitude towards everyone who helped make this release possible. From the stable of merry men in the Rails core to the hundreds of contributors who got a patch applied to everyone who participated in the community over the year. This release is a triumph for large scale open source development and you can all be mighty proud of the role you played. Cheers With the touchy feely stuff out of the way, lets dig into the feast and look at just a sliver of whats new Action Pack Resources. This is where the bulk of the action for 2. Weve got a slew of improvements to the RESTful lifestyle. First, weve dropped the semicolon for custom methods instead of the regular slash. So people1 edit is now people1edit. Weve also added the namespace feature to routing resources that makes it really easy to confine things like admin interfaces. Which will give you named routes like inventoryadminproductsurl and adminproducttagsurl. To keep track of this named routes proliferation, weve added the rake routes task, which will list all the named routes created by routes. Weve also instigated a new convention that all resource based controllers will be plural by default. This allows a single resource to be mapped in multiple contexts and still refer to the same controller. Example. avatars4. Avatars. Controllershow. Avatars. Controllershow. Issuu is a digital publishing platform that makes it simple to publish magazines, catalogs, newspapers, books, and more online. Easily share your publications and get. Action Pack Multiview. Alongside the improvements for resources come improvements for multiview. We already have respondto, but weve taken it a step further and made it dig into the templates. Weve separated the format of the template from its rendering engine. So show. rhtml now becomes show. And you can now have something like show. ERB renderer. So the new format for templates is action. A few examples show. Builder format, previously known as rxml, to render an index action for the applicationatomxml mime typeedit. HAML template engine not included by default to render an edit action for the custom Mime IPHONE format. Speaking of the i.

Youre encouraged to declare your own mime type aliases in the configinitializersmimetypes. This file is included by default in all new applications. Action Pack Record identification. Piggy backing off the new drive for resources are a number of simplifications for controller and view methods that deal with URLs. Weve added a number of conventions for turning model classes into resource routes on the fly. Examples. person is a Person object, which by convention will. Action Pack HTTP Loving. As you might have gathered, Action Pack in Rails 2. HTTP and all its glory. Resources, multiple representations, but theres more. Weve added a new module to work with HTTP Basic Authentication, which turns out to be a great way to do API authentication over SSL. Its terribly simple to use. Heres an example there are more in Action. Controller Http. Authentication. Posts. Controller lt Application. Controller. USERNAME, PASSWORD dhh, secret. Everyone can see me. Im only accessible if you know the password. USERNAME password PASSWORD. Weve also made it much easier to structure your Java. Script and stylesheet files in logical units without getting clobbered by the HTTP overhead of requesting a bazillion files. Using javascriptincludetag all, cache true will turn publicjavascripts. Along the same lines, weve added the option to cheat browsers who dont feel like pipelining requests on their own. If you set Action. Controller Base. That allows the browser to open many more connections at a time and increases the perceived speed of your application. Action Pack Security. Making it even easier to create secure applications out of the box is always a pleasure and with Rails 2. Most importantly, we now ship we a built in mechanism for dealing with CRSF attacks. By including a special token in all forms and Ajax requests, you can guard from having requests made from outside of your application. All this is turned on by default in new Rails 2. Action. Controller Base. Action. Controller Request. Forgery. Protection for more. Weve also made it easier to deal with XSS attacks while still allowing users to embed HTML in your pages. The old Text. Helpersanitize method has gone from a black list very hard to keep secure approach to a white list approach. If youre already using sanitize, youll automatically be granted better protection. You can tweak the tags that are allowed by default with sanitize as well. See Text. Helpersanitize for details. Finally, weve added support for HTTP only cookies. They are not yet supported by all browsers, but you can use them where they are. Action Pack Exception handling. Lots of common exceptions would do better to be rescued at a shared level rather than per action. This has always been possible by overwriting rescueactioninpublic, but then you had to roll out your own case statement and call super. Bah. So now we have a class level macro called rescuefrom, which you can use to declaratively point certain exceptions to a given action. Example. class Posts. Controller lt Application. Controller. rescuefrom User Not. Authorized, with denyaccess. Action Pack Cookie store sessions. The default session store in Rails 2. That means sessions are no longer stored on the file system or in the database, but kept by the client in a hashed form that cant be forged. This makes it not only a lot faster than traditional session stores, but also makes it zero maintenance. Theres no cron job needed to clear out the sessions and your server wont crash because you forgot and suddenly had 5. K files in tmpsession. This setup works great if you follow best practices and keep session usage to a minimum, such as the common case of just storing a userid and a the flash. If, however, you are planning on storing the nuclear launch codes in the session, the default cookie store is a bad deal. While they cant be forged so isadmin true is fine, their content can be seen. If thats a problem for your application, you can always just switch back to one of the traditional session stores but first investigate that requirement as a code smell. Action Pack New request profiler. Figuring out where your bottlenecks are with real usage can be tough, but we just made it a whole lot easier with the new request profiler that can follow an entire usage script and report on the aggregate findings. You use it like this. GET path. POST sessions path. And you get a thorough breakdown in HTML and text on where time was spent and youll have a good idea on where to look for speeding up the application. Action Pack Miscellaneous. Also of note is Atom. Feed. Helper, which makes it even simpler to create Atom feeds using an enhanced Builder syntax.
