Ruby on Rails guidence need

[Love U Ruby]

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

sqlite3 libxml2-dev \

&&

\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

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.

[Evaldo Santos]

Which tutorial/resource do you used?

[Colin Law]

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

What has that got to do with installing Rails?

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.

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 :-)

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,

Shall I need to install using `gem install SQLite3` ?

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`

[Colin Law]

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.

What happens when you install it, as has been suggested numerous times
on the this thread, by
gem install rails

which version of rail I need to install, as I am using ruby2.0.0p0 ?

[Colin Law]

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.

I'm a little confused by these posts as well.  If you executed the script you posted in your original post without any errors, rails should have been installed.  Obviously, you either didn't do that or there were errors.  

There are a few things in that script that are not, IMO, optimal.  First, I would not install rails with the --pre flag unless you are experienced with Rails and truly intend to test an unreleased version.  Second, his/her first action is to install a bunch of modules starting with build-essential, openssl, etc.  My only issue is that RVM, like Rails, is constantly being updated/upgraded and this list quickly gets dated.  I would install RVM as follows:

Install curl as follows:

sudo apt-get install curl

Then install RVM:

\curl -L https://get.rvm.io | bash -s stable

Once RVM is installed, run:

rvm requirements

it will give you an updated list of modules to install.

I would also run

rvm notes

it will give you other helpful notes on the install.

At this point, as has already been posted above, I strongly recommend www.railstutorial.org.  The tutorial assumes you have RVM installed already, but it then walks you through the installation of ruby, rails, git, etc.  so I'm not going to go into it.  There are two versions of the tutorial online, a 3.2 version and a 4.0 version (the 4.0 version is beta).  I agree with Colin, you should choose the version of ruby, rails, and gems that the tutorial uses.  This is particularly important with the 3.2 version.  If you don't use the versions of rspec and capybara that the tutorial uses, you will be very frustrated.

Thanks for your guidance. Now could You tell me should I need to remove
all that I have already installed,and follow the tutorial? If so then
how to clear/reset all that I did till now?

[Colin Law]

No need to start again, just carry on. Have you managed to install
Rails yet? You seem to do a lot of asking questions and not much of
actually doing anything.
