[Rails] retrieve app from github?

First you have to setup your laptop for git usage similar to what you had
done for your PC.
1. Install Git
2. Generate SSH keys
3. Add your laptop's public key to your github account (you can add as many
keys as you want, so do not modify your PC's key, just add a new one)

Then go to your repo page on github, copy the clone url shown there, and use
git clone <clone url>
to get your ruby app on your laptop.

There is nothing at github that says "clone url". There is a url
displayed when you go to a repo. So on my laptop, I went to the
directory I want my app to be in, rails_projects, and then I issued the
command you showed me. Then I cd'ed into the newly created app
directory, and I get this:

$ git branch
*master

However, I have another branch on github called 'updating users', and I
can't figure out how to download the other branch.

You have to create new branch locally and pull code from your git branch
into that one.
So something like this on your laptop:
Open up terminal and change directory to where your app is checked out.
Create a new local branch:
git checkout -b updating_users

Pull code in that branch from your github repo branch:
git pull origin updating_users

Alternatively you can also use this command:
git checkout -b updating_users origin/updating_users

Chirag: Are you sure about this. I thought that when you cloned a
repository it would come with all its branches, and all that the OP
should need to do is
git checkout <branch_name>

OP: if you have gitk installed (if you have not then do so, and also
git-gui) then try
gitk --all
and it should show you all the history and branches in the cloned repository

how I have been fetching other branches for a while now.
I looked up github guides to double check and it seems to confirm the
behavior - http://help.github.com/remotes/ scroll down to "clone"
documentation.

I think the missing link here is the command

$ git branch -r

This will show all the remote branches. From there you can then check them
out
locally. The data is in your local repo after the clone (so you can do this
off-line),
but only a default branch is checked out with git clone. Whis is the default
branch
can be set as "Default branch" on the github admin page for a project.
