Ruby on Rails guidence need

Hi,

I just completed Ruby learning and did complete some exercise also on
it. Now want to learn Ruby on Rails also.So what would be the good
approach or from where to start,to learn it quickly and conceptually.

I also had installed also Ruby as mentioned in this url :
https://gist.github.com/pcjpcj2/5443017


sudo apt-get -y install build-essential openssl libreadline6
libreadline6-dev curl git-core
zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev
sqlite3 libxml2-dev
libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison

&&

\curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enabled

&&

echo ‘[[ -s “$HOME/.rvm/scripts/rvm” ]] && . “$HOME/.rvm/scripts/rvm” #
Load RVM function’ >> ~/.bash_profile

&&

source ~/.bash_profile

&&

rvm install 2.0.0-p0

&&

rvm use --default 2.0.0-p0

&&
ruby -v

&&

gem install rails --pre


So now what more I need to do for Rails installations?

So please help me to get a good start with ROR.

Have a look at railstutorial.org (which is free to use online) and the
Rails Guides.

Excellent, and welcome.

Start with the official Rails guides, which I think are excellently
written:

http://guides.rubyonrails.org/index.html
http://edgeguides.rubyonrails.org (if you’re living on the edge)

Then move on to one of these great tutorials:

http://railsforzombies.org
http://ruby.railstutorial.org

Which tutorial/resource do you used?

Thanks for the guidance. Could you help me to install Rail also? What
are the things I need to install for it. I have installed Ruby2.0.0
using RVM as I mentioned at the top.

I think you have installed it when you installed rvm (–rails). Try
rails -v
in a terminal.

Once you have installed rvm then gem install will install into the rvm
environment. So
gem install rails
should do what you want. If you want a particular version then, for
example
gem install rails --version 2.3.2

To install a different version of Ruby (should you wish to do so)
then, for example
rvm install 1.9.2
and to use it
rvm use 1.9.2

I am using SublimeText2 editor for my Ruby programs.

What has that got to do with installing Rails?

No matter, gem install rails is how you’re going to install it. You
should create a gemset for your project first (IMO, one of the best
features of rvm).

what the database I need to install also?

Whatever you want, or are most familiar with, or is easiest :slight_smile:

SQLite3 is the default, MySQL is probably most widely used, and
some people prefer Postgres. For learning purposes, I’d go with one
of the first two.

HTH,

When I was on windows, I used the tutorial : http://railsinstaller.org/
.
Here I did install Ruby,Rails,MSSQL and SublimeText2 editor - a total
package for rails programming.

Looking for the same way to do in my Unix.

I am using SublimeText2 editor for my Ruby programs.

You need to install the database of your choice; that has nothing
to do with Rails per se’.

Then when you generate your new app, you specify the db and
the generated Gemfile will have the appropriate gems, all of which
will be (by default) installed for you.

See rails new --help

No, you have already installed the sqlite3 db driver (in the apt-get
install in your first post). The gem itself will be automatically
installed when you run bundle install. I suggest working right
through a good tutorial such as railstutorial.org (which is free to
use online) and you will learn about the basics of rails including how
gems are automatically installed based on the contents of your
Gemfile.

The program ‘rails’ can be found in the following packages:

  • rails
  • ruby-railties-3.2
    Try: sudo apt-get install

You should not choose the version of Rails that is right for Ruby, you
should decide which version of Rails you want then make sure you have
an appropriate version of Ruby. Remember that with rvm you can easily
install another version of ruby. Also you can install multiple
versions of Rails.

Assuming that you are starting by working through a tutorial then
install the version of rails that the tutorial requires.

When you come to writing your own app then presumably you will want
the latest stable version, or perhaps you want to go with the beta
version of Rails 4. That is for you to decide.
