I’m trying to learn how to use ruby on rails. Just two weeks ago I’m
learning how to program in Ruby, but now I’m ready to get onto with
rails. I got a book for rails but it shows me rails examples that only
work with rails 1.2.3. I follow the examples, but many are not working.
For example, scaffold is not working with 2.1.0 (rails version install
in my computer.
My question is, how do you go about scaffold in rails 2.1.0? Some
pagination is not working out of the box such as will_pagination and
classic_pagination. Ubuntu 8.10 is making rails more difficult, and
installing will_pagination from gems didn’t do the trick.
Anyone know a complete tutorial that teaches how to install all
necessary gems/plugins/debian packages that will help me smooth-sailing
in my ruby on rails adventure? Thank You.
Also I couldn’t find a good beginning ruby on rails book that is
up-to-date, and I know ruby on rails is a very fast moving framework as
ruby is also a very fast moving programming language – things are
changing constantly for the better. Any guide to better rails way?

Forget scaffolds. They are just the bait - the teaser.
Learn Rails by learning to…
create a model with script/generate
create its migration into a database
write unit tests which force that model to have methods
integrate your code into git or svn
paint a page in HTML
use tidy to clean it up
create a controller & its view
convert it to html.erb, in the view
run your app with webrick and look at it
put <%= tags %> into it
write tests showing the tags do the right thing
That’s the core cycle. Anything else - billions of topics, including
threading,
paging, Ajax, etc, you must Google for, after you understand and work
that core
cycle. And all the books cover the core cycle (right??!).
Thank so much for your guides guys! Ruby is so elegant that I’m falling
in love with Rails too. It’s funny that I heard the hype of rails but
didn’t bought into it like most people until I saw Ruby’s elegant codes.
I’m not a programmer but I have learn a little C, Visual Basic, PHP, and
don’t remember any of those :). Especially PHP, I saw how useful it is
as it has large base of open source software, but whenever I look at its
code, I think to myself, it is a mess. I put off learning coding for
very long time, and just concentrating in some networking stuffs, but I
picked up a Ruby books from Barnes and Noble once, and I fell in love
with Ruby :). Maybe because I like the idea of bringing art and fun
into programming than anything else. Plus, Ruby is so easy to
understand and to play around with than other programming language, at
least I didn’t yawn when I read the examples :).
I think that in the future we’re going to be relying less and less on
books in the traditional sense and more and more on up-to-date,
community sponsored and updated documentation to handle a lot of what
books handle right now … especially when working with fast-moving
web frameworks like Rails.
That’s just what I see. Rails Guides is an incredible resource, and I
hope that the Wiki will become even more of an extension of the Guides
than it might have been in the past.
If you are looking for some books to get started with, check out
Simply Rails 2 (still mostly relevant), Learning Rails, and Agile Web
Development with Rails (3rd Edition). Those three are the three I
recommend at the moment, but you always need to be aware that you will
have to fill in blanks and think on your feet.
Hi there, I know it can be frustrating, even for those of us that have
been in it for a while. (freezing the environment is a real chore)/
My suggesting is to forgo the print books and go straight to peepcode.com and the pragmatic programmers(http://www.pragprog.com/
titles/rails3/agile-web-development-with-rails-third-edition) sites
and watch the up-to-date screen casts and buy the pdfs.
The great part about rails is it’s agility, and that works both
ways.
My suggestion is also to really learn the ruby language and the rest
will follow.
Lots of good advice so far… I would also recommend checking out Railscasts.com. Ryan B. offers great Rails instructional videos for
free.
Really, the best way to learn is to just immerse yourself: start
building a blog or web application, watch Rails videos everyday, and
learn a different Ruby construct every other day.
All advices are really awesome so far! Thank you guys. With your
suggestions, I have so far immerse myself into RoR a bit more, messing
around with scaffold, and it was an eye opener. Man, scaffold is really
making things go fast as if I’m on a super fast jet. LOL. I know
scaffold is just a bait, because if I want to have a more specific
features and so on, I have to add extra ruby codes to what scaffold
already has generated. Though, scaffold has created CRUD application in
its basic form is already too amazing. All I did was calling
“scripts/generate scaffold feature column_name:column_type”, then do
rake db:migrate, and then if I want to change or add anything to db, I
only have to do script/generate migration Add…To…(name convention)
then rake db:migrate again. As now I knew MVC structure better, I think
I could using scaffold (for fun) to create something basic for the web
in few minutes. LOL. To pretty up the presentation, I could always add
css to the views.
