Rails 2.3.4 Vs Rails 3 + Book - Beginner in RoR - ruby-on-rails

I have started with Ruby and Rails development and I am a Java developer from the last 2 years (student). I am in for two things:
Learn Ruby
Make my website on ROR
I have Agile Web Development with Rails, 2nd Edition.
So, here are my questions:
How is the Agile Web Development with Rails book to start with, where I don't know anything about Ruby and proficient with Java.
What is the difference between 2nd and 3rd edition? People say the changes are irrelevant for a starter, how far is that statement correct?
Should I start with Rails 2.3.4 or Rails 3 (around the corner)? Rails3 It Is!

The Agile book is good, but the 2nd edition is for Rails 1.2 - which is quite old now! You could buy the 3rd edition (which is for Rails 2), but with Rails 3 coming out soon that'll probably also be outdated soon.
My recommendation is the website: http://www.railstutorial.org/book
It's a really well written online book called 'Learning Rails by Example', it gives a thorough introduction to Rails (using the latest Rails 2.3.8). Two of my colleagues have used it recently to get into Rails.

As someone who went on the same path, from java to rails, recently, I'll give my two cents.
Start with whatever version you have book/tutorial/guide for. (assuming it's good book/tutorial/guide, of course) Unfortunately, backwards compatibility is a big problem for rails and I often saw that code examples created just 2-3 years ago need significant fixes to become workable now. And fixing them especially difficult if you're a greenhorn.
As for "Rails 3 is cooler" argument, you could skip it as well and wait for Rails 5. IMHO, if you're doing a website for fun/to learn, both second and third versions will give you basic understanding of the platform and language. And once you know it, 'upgrading' your knowledge to the next version is much simpler than learning it anew.
Good luck with your quest, you'll need a lot of it :)

I don't have the Agile Book, but I can answer question 3.
Firstly, I have no idea why you would start with 2.3.4 when theres 2.3.8 out already.
Secondly, I would might do a little testing and mess around a bit with 2.3.8, but not start anything big and wait for Rails 3. This is because Rails 3 is largely different but better and you will probably want to upgrade an application once it comes out. Hence, it would be smart to wait for Rails 3 to be released before starting any large projects so that you don't have to go through the trouble of upgrading.
As a bit of note on question 1, I have done fine learning without the Agile Book, but there are probably some thing I could pick up better with that book rather than looking things up on Google and the RDoc.

Should I use Rails 2.2 vs Rails 3 for learning?

Frustratingly my laptop has Rails 3 on it, although I cannot find much supporting documentation on how to use Rails 3, excepting the API reference.
There appears to be a significant amount about regarding rails 2.2. Would you recommend downgrading and learning 2.2 or just plough ahead with 3 and hope for the best?
Highly recommend continue with Rails3. No new apps out there are going to be created with Rails 2.3 -- as gems and engines are created and updated, your 2.3 app will get out of date.
The documentation is still coming for Rails3 out on the blogosphere, but searching for "Rails3 where conditions" gives good rails3 results.
If you're willing to buy documentation, Agile Web Development with Rails (4th edition) was quite excellent in its first edition, and was how I learned. Its 4th version covers rails 3.
If you don't have any experience yet, you'd better start with the latest version. As for no documentation, how about Rails Guides? I think that's pretty awesome.
If you really are stuck with Rails 3, at least use Rails 2.3.x instead of 2.2.
Rails tends to move pretty fast, so it hard for the documentation to keep up. This is a known problem though, and http://railstutorial.org/ was made to be a comprehensive tutorial that will be maintained by the rails evangelism team. (you can buy the book/screencast, or just go to the "book" link on the menubar, it is freely available there)
Rails 3 was a great release, I would recommend sticking with it if at all possible.
As captaintokyo and Jesse Wolgamott I strongly encourage you to use Rails3. Another great ressource to learn about Rails3 is http://railstutorial.org/ .
I agree, start learning on Rails 3. Everything is moving that way quickly.
If you knew you were going to be working on rails 2.* applications (you were starting a new job next month and they had rails 2 apps already installed and were not upgrading them this year) is the only reason I would give to start with 2.*.

Is it worth to start learning rails 2 or should i wait until books on rails 3 are available?

I had always dreamed about learning rails and the ruby language, but there seems to be a big change comming with the new rails 3 release. So are there generally huge differences between 2 and 3? Should i probably start with rails 3 when books are available since this is the way i learn the best?
Indeed, the best targets are Rails 3 and Ruby 1.9.2, especially if you need to start a new project or learning a new language.
If you are completely unfamiliar with both Ruby and Rails, then you first need to start with Ruby before working with Rails. For the time you will be more acquainted with Ruby, chances are most of the Rails 3 books will be released or in beta version.
In fact, there are several Rails 3 books almost finished. Agile Web Development with Rails and The Rails 3 Way are probably the most effective examples. By the way, you can already start learning Rails 3 right now. Rails has great documentation ;)
You can start learning Rails 3 now, there are plenty of resources already on the net, e.g. here: http://railsnotes.com/rails-3/
You could also pick up the beta version of Agile Web Development http://pragprog.com/titles/rails4/agile-web-development-with-rails
Don't underestimate the value of online documentation!

Should I use Rails 3 or Rails 2.3.8

I heard Rails 3 is almost ready to be released from beta, meaning its a stable version. But of course the real date still unknown.
So I'm looking for advice from a good RoR developer. Do you think I should learn and use Rails 3 RC version or use Rails 2.3.8? If I use the RC version now will it be hard to upgrade to the stable Rails 3 version?
Is there a decent RoR developer out there than can offer some guidance?
Thanks.
I don't know what a rock developer (!) is, but I'd recommend going with Rails 3 rather than Rails 2.x. Rails 3 represents the future direction of Ruby on Rails, so it's worth getting up to speed with it as soon as you can. To be frank, Rails 2.x is now an evolutionary dead-end. There shouldn't be any significant changes between the Rails 3 Release Candidate and the final version.
The barriers to adopting Rails 3 you might encounter are:
its availability on your production stack
plugin/gem compatibility
For the first issue, I know that the popular Heroku for example are tracking the Rails 3 beta releases pretty closely. Regarding the second issue, not all plugins or gems are compatible at the moment, but a lot of the most popular ones are. If there are specific plugins or gems that you need to use then check here.
If you need to get a project off the ground now, then by all means go with Rails 2.3.8. It's the safe choice.
There are some significant changes in Rails 3. Some tools will be available to help you upgrade. But no automated tool will ever completely convert your 2.3.8 application to Rails 3. It's hard to tell how much effort is involved, that really depends on your application.
That said, if you are new, learning, and not expecting to release anything for several months, Rails 3 is the right choice. By the time your grok Rails and have something in production, Rails 3 will likely have stabilized, and nobody will be looking back.
Use rails 3!! The RC is still in the pipeline, but it's more or less good to go and you won't need to make any code changes when the final release is made
Here are some reasonable resources to get you started with it

Gettings started with Ruby on Rails 2.0 for Windows

So like many people, I'm excited about Ruby on Rails. Being a Windows user, I downloaded InstantRails, got it going, and followed along with the screencast on how to make a blog with RoR 2.0 in fifteen minutes. I used Notepad++ as my text editor, because that's what I've traditionally used for writing the PHP-based websites I've done in the past. I was a little envious of Mac users and how they get the really attractive-looking TextMate, but I managed to follow through the entire screencast and get everything working smoothly.
However, I was lost most of the time.
I know plenty of programming and scripting languages over the years - C++, JavaScript, PHP, HTML, and Lua just to name a few. I don't know Ruby, but I understand a lot of how it works, as far as the syntax is concerned, but I don't understand a lot of the logic behind why certain files do certain things, and that sort of thing.
Also, I tried Aptana with RadRails, but found it difficult to set up. Is there any concrete tutorial for getting it set up and working fully with Ruby on Rails 2.0?
Should I maybe just wait for more RoR 2.0 tutorials to come out before attempting to learn RoR? Or should I just plow on through and experiment until I figure it out?
Also you may want to look into NetBeans, it has great support for ruby and rails. They also provide several focused tutorials and even viedos.
http://www.netbeans.org/kb/trails/ruby.html
Another excelent source of focused tutorials is http://railscasts.com/ by Ryan Bates.
On the ruby side, I strongly recommend The Ruby Way, and if you are into screencasts, the Pragmatic Programmers have some cheap and excelent ones on ruby object model and metaprogramming by Dave Thomas.
Pragmatic Programmer's Agile Web Development with Rails is an excellent book to get started with.
There is a RoR 2.0 BETA book available as well.
If you are really serious about learning Rails, my advice is to get a good book and read it (I know.. programmers don't read books, but you should!). A "good book on Rails" usually contain a chapter on Ruby, but there are plenty of resources on the web to get you going.
According to Ruby on Rails guides:
It is highly recommended that you
familiarize yourself with Ruby before diving into Rails. You will
find it much easier to follow what's
going on with a Rails application if
you understand basic Ruby syntax.
Rails isn't going to magically
revolutionize the way you write web
applications if you have no experience
with the language it uses.
I'm personally using Simply Rails 2, which uses (surprise, surprise) Rails 2. It walks you through the development of a Digg clone.
If you still don't wanna use a book, you should check out Ruby on Rails guides and the Ruby on Rails Wiki. AFAIK, They are being regularly updated to keep up with new releases of Rails.
The Rails Way is also a good book. I use it everyday as a reference book.
You could always check out the awesome Peepcode screencast series:
Rails 2 from scratch part I
Rails 2 from scratch part II
You'll be off and running in no time after watching those. I would also recommend Railscasts, a (free) weekly screencast on Rails, usually focusing on a single feature or implementing a concept in a wonderfully produced manner.
From what I've read, though, it looks like many of these books and such are now at least partially outdated with the advent of Rails 2.0. Is this true?
InstantRails has not been updated for a while, check out Rubystack, which is a similar project but we also include a bunch of other tools: Apache, MySQL,Imagemagick, etc.

Learning Ruby on Rails

Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
As it stands now, I'm a Java and C# developer. The more and more I look at Ruby on Rails, the more I really want to learn it.
What have you found to be the best route to learn RoR? Would it be easier to develop on Windows, or should I just run a virtual machine with Linux?
Is there an IDE that can match the robustness of Visual Studio? Any programs to develop that give a good overhead of what to do? Any good books?
Seriously, any tips/tricks/rants would be awesome.
I've been moving from C# in my professional career to looking at Ruby and RoR in my personal life, and I've found linux to be slightly more appealing personally for development. Particularly now that I've started using git, the implementation is cleaner on linux.
Currently I'm dual booting and getting closer to running Ubuntu full time. I'm using gedit with various plugins for the development environment. And as of late 2010, I'm making the push to use Vim for development, even over Textmate on OS X.
A large amount of the Rails developers are using (gasp) Macs, which has actually got me thinking in that direction.
Although I haven't tried it, Ruby in Steel gives you a Ruby IDE inside the Visual Studio world, and IronRuby is the .NET flavor of Ruby, if you're interested.
As far as books are concerned, the Programming Ruby (also known as the Pickaxe) book from the Pragmatic Programmers is the de-facto for learning Ruby. I bit the bullet and purchased that book and Agile Web Development with Rails; both books have been excellent.
Peepcode screencasts and PDF books have also been great for getting started; at $9 per screencast it's hard to go wrong. I actually bought a 5-pack.
Also check out the following:
Official Rails Guides
Railscasts
railsapi.com or Ruby on Rails - APIdock
The Ruby Show
Rails for Zombies
Softies on Rails - Ruby on Rails for .NET Developers
Rails Podcast
Rails Best Practices
I've burned through the backlog of Rails and Rails Envy podcasts in the past month and they have provided wonderful insight into lots of topics, even regarding software development in general.
Beware, the rails world is a massively frustrating mess of outdated and inconsistent documentation and examples. It is maybe one of the fastest moving and most faddish development communities there is. By the time you learn something it will already have changed. Even the books are not consistent in which version of rails they are talking about. Documentation by blogging! enough said.
I currently do RoR on windows. My advice is to avoid windows if you can. Lots of things don't work and the rails community really really doesn't care about you. The move to Git has really messed me up since it doesn't work very well on windows. A lot of gems will fail because of this (Heroku looks like a cool tool - too bad for me it can't handle window's Git setup). Capistrano is out. It goes on and annoyingly on.
Plus, in the back of your mind, you always wonder when something doesn't work "Is it a rails/windows problem?" I am not sure this is solved by using linux because linux brings its own hassles like constantly having to upgrade all those different dependencies, etc...If that's the kind of thing you enjoy it might be an okay choice for you. Those days of enjoying system fiddling are behind me and I just want to get on with doing my work. I am planning on installing ubuntu on a home machine just so i can get familiar with things like capistrano so maybe my opinion will change.
I'd highly suggest if you are going to do rails dev for any amount of time you seriously consider getting a Mac. If you value your time and sanity it will pay for itself almost instantly. Depending on how you value your time 10 hours of debugging windows/linux setup problems and you have spend as much as a Mac costs anyway.
Rails is a joy compared to what it replaces but it is a bit of a pain in that its proponents skip right past a lot of the boring but important stuff like documentation, compatibility issues and community building. It is way more powerful than other frameworks like Django but I sometimes look over at the Django documentation and community and sigh like a guy with a wild sexy girlfriend looking at his friend's plain but sane and stable wife. But then rails adds a feature and I go "Ohhh shiny!"
IMO the Rails Screencasts are better than the Peepcode screencasts. RubyPlus also has screencasts, mind you, they are bit rough around the edges. BuildingWebApps has a free online course that starts doing screencasts halfway through.
Path of least resistance:
Have a simple web project in mind.
Go to rubyonrails.org and look at their "Blog in 15 minutes" screencast to get excited.
Get a copy of O'Reilly Media's Learning Ruby
Get a Mac or Linux box.
(Fewer early Rails frustrations due to the fact that Rails is generally developed on these.)
Get a copy of Agile Web Development with Rails.
Get the version of Ruby and Rails described in that book.
Run through that book's first section to get a feel for what it's like.
Go to railscasts.com and view at the earliest videos for a closer look.
Buy The Rails Way by Obie Fernandez to get a deeper understanding of Rails and what it's doing.
Then upgrade to the newest production version of Rails, and view the latest railscasts.com videos.
I wrote a post called "Getting Started With Rails -- What I wish I knew" that many people found helpful.
The basics:
Agile development with Rails (book)
InstantRails for quick ruby/rails environment on Windows
Aptana as the IDE
Subversion for version control
The online tutorials are decent but scattered. Invest $30 in a book for a more comprehensive understanding.
I've found http://railstutorial.org/book to be a great resource for learning Rails
I really enjoy RubyMine from Jetbrains. It seems like a very full featured IDE something I miss from many of the other alternatives out there. Also for a simple env I enjoy e the text editor. Plain and simple.

There's a very solid ongoing series on NETTUTS right now that you may be interested in.
http://railsforzombies.org/ is a nice one. Introducing an all new way to learn Ruby on Rails in the browser with no additional configuration needed.
As you, I'm a java/C# developer trying to learn more Ruby On Rails.
I'm taking the free online course Ruby on Rails Programming with Passion, is a good introductory course, check it out.
We are using NetBeans as IDE (win/mac/linux/solaris), if you are used to Eclipse or Visual Studio, there is a good chance you will like it.
Fantastic decision! It is extremely useful to get a grounding in Ruby before going to Rails so here is my take on the best path to Rails:
Learn to Program by Chris Pine - You can read this in an afternoon to get a feel for the Ruby language.
The Well Grounded Rubyist by David Black - Like the title says it will give you an excellent grounding in the language.
Eloquent Ruby by Russ Olsen - This book is sublime, it reads like a novel.
Ruby Best Practices by Gregory Brown - By this point you should be ready for the advanced level of this book.
Rails for Zombies - Fun tutorial you can complete in an afternoon.
Rails Tutorial by Michael Hartl - Fantastic (and free) tutorial and I have heard his accompanying screencasts are amazing.
Agile Web Development with Rails by Sam Ruby - By the time you are finished this you are now a completely capable Rails person!
Aside from books the most important thing is to get feedback on what you are doing. To do this I recommend spending time in irc.freenode.net #ruby and #rubyonrails. It is also extremely helpful to post things you are working on or having trouble with here on stackoverflow as the comments, explanations and different way of thinking about things that people provide are invaluable.
You should also definitely check out the Ruby Rogues podcast, they provide invaluable information and the commentators are all extremely respected people in the Ruby community. And for your viewing and reading pleasure (in that order,) head over to Ryan Bates's Railscasts and then Eifion Bedford's Asciicasts.
Finally, I recommend looking into different gems on github, reading the code and then contributing to them. You don't have to get overly ambitious and do massive recodes, especially at first. Just start with small things like editing and making the README files a little easier to read.
I don't use an IDE but at Railsconf I saw a demo of Rubymine from Jetbrains and it seemed pretty amazing.
0) LEARN RUBY FIRST. This is very important. One huge advantage of Rails is Ruby: a great language that is very powerful but also marvelously easy to misunderstand. Run through a few Ruby tutorials online. When coding challenges come up on Daily WTF, write them in Ruby. You'll pick it up fast.
1) Go buy the book "Ruby for Rails"
2) Check out a Rails tutorial and subscribe to the Riding Rails blog.
3) Standup an app locally. Don't use scaffolding.
4) When you install plugins into your app, go look at the code in that plugin (in your vendor directory) and learn it. It is one of the best ways to learn Ruby and Rails internals. When you don't understand how something works, post it here and 1,000 people will help you.
As for your other questions:
Yes, you will need a Linux environment to develop in. You can develop Rails on Windows, but that doesn't mean it should be done. Lots of gems aren't up to speed on Windows.
NetBeans works well as an IDE. If you're on a Mac, you'll get street cred for using Textmate.
Find a nearby Ruby users group and start attending that. I've found that is a great way to meet a lot of people who are passionate about development and willing to teach.
I'm surprised there has been so little mention of Why's (Poignant) Guide to Ruby. Why may not be around anymore but the guide is easy to find on the net (Google points here first) it's a very easy read and provided my introduction to Ruby.
After the guide, I'd recommend either one of the books the others have suggested, or following the series of screencasts at Learning Rails which is how I picked up enough Ruby on Rails to be dangerous. Once you've completed the Learning Rails series. what you want to do with Rails will start to diverge from the general tutorials and that's where Railscasts becomes a wonderful tool. There's not much can be done with Rails that Railscasts hasn't touched on at some point.
My first suggestion would be to learn a little about symbols first. Rails isn't the smallest framework ever, and while there's definitely lots to learn, most of it will start to make sense if you have at least a little bit of understanding what makes it different ("special") from other languages. As pointed out, there's no exact analog in any of the major languages, but they're heavily used by Rails, in order to make things read straightforwardly and perform well, which is the reason I brought it up. My very first exposure to Rails was also my first time looking at Ruby (well before 2.0), and the first thing that caught my eye was the goofy :things they were passing around, and I asked, "WTF is that?"
Also, check out RubyQuiz, and read other peoples' answers on that site.
I came from a Java background to Ruby to. I found this tutorial helpful http://www.ruby-lang.org/en/documentation/ruby-from-other-languages/to-ruby-from-java/. When it comes to learning rails I cannot say how much I use script\console. It allows you to play with the code and learn how to do things that you are not sure about.
The only book I ever bought was Agile Web Development with Rails, Third Edition http://www.pragprog.com/titles/rails3/agile-web-development-with-rails-third-edition. It was quite useful and provided a good overview of the Rails framework. In addition to that I regular watch Railscasts(http://railscasts.com), which is a great screen casting blog that covers all kinds of Rails topics.
I personally prefer using Linux (because git works better). But, I have also used windows and besides git I do not think the OS choice will impact your programming.
I use netbeans for my IDE and occasionally vim (with the rails plugin). I like netbeans but, I find that it can still be a little flaky when it comes to the Rails support (not all the features work all the time).
This looks like a great resource for people like me who are coming from PHP to RoR
http://railsforphp.com/ There's also a book Rails for PHP Developers
I used to do Java and C# on Windoze.
I'd second these sources:
IDE: Try Apatana RadRails 3 Sneak Peek: http://www.radrails.org/3. Its the closest thing you'll get to Visual Studio. I play with it here and there but still love the lightness of Textmate.
OS: Mac OS gets the most if not all love from Ruby community. Anything else is treated like a bastard child.
Books:
The Pragmatic Programmers' Guide (the pickaxe book)
Agile Web Development with Rails
Screencasts:
Peepcode (pay) is a nice way to pick up concepts quickly
Railscasts (free) is a good weekly way to pick up new gems and concepts incrementally
Railscasts (pro) is also a good way to pick up concepts for a pretty low price.
The ubber source for anything Rails is http://www.rubyonrails.org/ if they don't have it on the site you probably don't need it.
A quick cookbook is Ruby on Rails: Up and Running you can get it from O'Rielly or search Google for a on-line version. They walk you though the conventions of Rails and use Instant Rails which is ok.
A better Rails book "Agile Web Development with Rails" This is the soups to nuts of Rails. It walks you though downloading and setting up Rails, Gems, everything.
If you want are a Java 'guy' and want a transition book O'Reilly has "Rails for Java Developers" http://oreilly.com/catalog/9780977616695/?CMP=AFC-ak_book&ATT=Rails+for+Java+Developers
Another IDE you could try is Aptana.
Oh I almost forgot. Here are a few more Ruby screencast resources:
SD Ruby - the have a bunch of videos online - I found their Rest talks SD9 and SD10 to be among the best of the intros. Other rest talks assume you know everything. These ones are very introductory and to the point.
Obie Fernandez on InfoQ - Restful Rails. I've also read his Rails Way book and found it informative but really long winded and meandering and the quality is a bit inconsistent. I learned a lot from this book but felt it was a bit punishing to have to read through the repetition and irrelevant stuff to get to the good bits.
Netbeans is a nice hand holding IDE that can teach you a lot of language tricks if you have the patience to wait for its tooltips (it is a painfully slow IDE even on a really fast machine) and you can use the IDE to graphically browse through the available generators and stuff like that. Get the latest builds and you even have Rspec test running built in.
Bort is a prebuilt base app with a lot of the standard plugins already plugged in. If you download it and play with it and figure out how it is setup you are about halfway to creating your own full featured apps.
I bought the book "Simply Rails 2" by Patrick Lenz.
This book is a great introduction to Ruby and Ruby on Rails.
As for my ruby installation and db, I used Cygwin.
It comes with PostgreSQL, ruby and svn.
I like PostgreSQL because I come from an Oracle
background so it feels more comfortable than MySQL.
The other utility I found really useful was pgAdmin
for accessing the PostgreSQL databases.
The first thing I needed to do was to get gems installed.
I got the gems tar file from rubyforge
wget "http://rubyforge.org/frs/download.php/60718/rubygems-1.3.5.tgz"
Once I had gems setup, I installed
rails
ruby-postgres
postgres
rack
I also needed an issue tracking system so I installed redmine.
wget "http://rubyforge.org/frs/download.php/60718/rubygems-1.3.5.tgz"
I found that using a UNIX-like environment (Cygwin) was
preferable in my case because many of the tutorials were
taylored for OS X or Linux.
The text editor I use is Textpad. I'm looking for an alternative.
I think that vim with the rails plugin might work nicely.
I come from a non-programming background. I have learned PHP on my own and recently joined a firm that specializes in Ruby on Rails. They have a comprehensive Rails training program, which is flexible enough to accommodate whatever changes we want to implement. Though I am not a rails pro, I would like to share my experience with rails. I hope that it helps.
Here is the path I am following [combined with tools I am using]
Start with a simple ruby guide. It will help a lot, since entire rails framework revolves around classes and objects.
Environment and OS are not important. Though I am working on a Mac, I frequently work on Linux and Windows, and I do not face any problems.
Start with a good book which explains using a demo app. [I am using Agile Web Development with Rails - By The Pragmatic Bookshelf]. There are many other good books as well.
Once you are done with the application, you will have a good idea of the framework.
Try to understand the SQL queries generated by Active Record module.
Go through the Rails Guides. You will find the framework a lot easier.
Keep practicing.
Few imp points
It takes years to learn a language completely. So be patient and do not stop learning.
Go through rails api as when required. [While developing your first app]
Google the things which you do not understand. People have written great articles on almost all topics.
Use Stackoverflow :-) [Only when you are not able to find the solution on your own.]
Load railscasts on your phone or video player. Watch 'em while travelling or in your free time. They are of few minutes each. You will learn a great deal of things and also learn the best way of doing things.
Tools
Shell [in Mac and Ubuntu]
Editor [Textmate in Mac, Gedit in Ubuntu and Notepad++ in Windows]
Firefox with Firebug installed for testing.
Finally I have one thing to say "Keep trying". All the best.
The fastest way to learn anything, Ruby on Rails included, is pair programming.
Find someone who knows Rails, pick an example app, sit down, and work through fixing bugs, adding features.
The knowledge sharing is unbelievable.
My suggestion is just to start - pick a small project that you would generally use to learn an MVC-style language (i.e. something with a database, maybe some basic workflow), and then as you need to learn a concept, use one (or both!) of
Agile Web Development with Rails
or
The Rails Way
to learn about how it works, and then try it.
The problems with Agile Web Development are that it's outdated, and that the scenario runs on too long for you really to want to build it once; The Rails Way can be hard to follow as it bounces from reference to learning, but when it's good, it's better than Agile Web Development.
But overall they're both good books, and they're both good for learning, but neither of them provide an "education" path that you'll want to follow. So I read a few chapters of the former (enough to get the basic concepts and learn how to bootstrap the first app - there are some online articles that help with this as well) and then just got started, and then every few days I read about something new or I use the books to understand something.
One more thing: both books are much more Rails books than they are Ruby books, and if you're going to write clean code, it's worth spending a day learning Ruby syntax as early as possible. Why's Guide to Ruby is a good one, there are others as well.
I think the screencasts and short books from Peepcode are really good. They have screencasts to get you started and have some as you get more advanced.
There is a site called Softies on Rails that is written by a couple of ex-.NET developers that may be of some use. They have a book called Rails for .NET Developers coming out in the next few months...
I started out on a Windows box using the RadRails plugin for Eclipse and the RubyWeaver extension for Dreamweaver (back during the 1.x days of Rails). Since then I have moved to a Mac running TextMate and haven't thought of going back.
As for books, I started with The Ruby Way and Agile Web Development with Rails. It definately helps to build a background in Ruby as you start to make your way into Rails development.
Definately watch the Railscast series by Ryan Bates.
I have found "The Rails Way" by Obie Fernandez excellent and often found myself referring to it when Agile Web Development with Rails didn't seem to go far enough. Obie Fernandez has a decent blog too.
Wait a couple of months for Learning Rails by Simon St. Laurent, Edd Dumbill to come out in November. That series of books is stupendous, and this book will cover the latest version of Rails.
