Setup Environment

Since it's basically a Ruby Web application, you should firstly have Ruby installed. RVM is choosen as the Ruby Installer. In most cases, simply type:

$ curl -sSL https://get.rvm.io | bash -s stable

will do the installation automatically for you. If you want to do some customization, here is a detailed guide.

Once the Ruby is installed, you need clone this repo to you local enviroment:

$ git clone git@github.com:abruzzi/letusgo-server.git
$ cd letusgo-server

And then you should be able to see something like:

ruby-1.9.3-p545 is not installed.
To install do: 'rvm install ruby-1.9.3-p545'

Try to following the instruction, and install the correct version of ruby. After that you need install the bundler gem by yourself, and use bundler to maintain other dependencies. Install bundler itself is easy:

$ gem install bundler

Then you can use command bundle to install all other gems:

$ bundle install

Once all the dependencies are installed, you are done of the environment part

Application setup

Now we will start to do the application setup. Firstly, do the database setup like this:

./setup.sh

After this, you should see there are 2 files end with .sqlite3 in the folder db/:

$ ls -al db/*.sqlite3
-rw-r--r--  1 jtqiu  staff  20480 Nov 16 13:29 db/development.sqlite3
-rw-r--r--  1 jtqiu  staff  20480 Nov 16 13:48 db/test.sqlite3

Then you can lunch your application by using shotgun like this:

$ shotgun

And you should see something like this:

== Shotgun/WEBrick on http://127.0.0.1:9393/
[2014-11-16 14:22:45] INFO  WEBrick 1.3.1
[2014-11-16 14:22:45] INFO  ruby 1.9.3 (2014-02-24) [x86_64-darwin14.0.0]
[2014-11-16 14:22:45] INFO  WEBrick::HTTPServer#start: pid=8889 port=9393

that means the application is started successfully, type http://127.0.0.1:9393/products in your browser and you should see an empty array like [], then you are done.

Use Ctrl-C to terminate the application, try to run the following command to test the application:

$ RACK_ENV=test rake specs

And you should see 3 test cases are passing:

...

Finished in 0.11592 seconds (files took 0.60523 seconds to load)
3 examples, 0 failures

That's it.
