High scores

Exercise consisting of buiding a high score service for a new game console using Ruby on Rails.

Set up environment

For running a clean clone of the app:

$ vagrant up
$ vagrant ssh
$ cd /vagrant
$ bundle install
$ rake db:create db:migrate db:seed
$ rails server -b 0.0.0.0 -p 3000

Main aspects

• Responsive design with Bootstrap
• Dependent destroy of scores when destroy a game
• Service object for ranking logic

API calls

To communicate new scores a REST API is offered, the endpoint is shared for HTTP requests and JSON request by convention. So it's important to specify both Content-Type and Accept headers to application/json in order to post payload in JSON format correctly. An example below:

POST /scores HTTP/1.1
Host: localhost:3000
Content-Type: application/json
Accept: application/json

{
"score": {
"player_email": "me@example.com",
"score": 10012,
"game_id": 12
}
}

And the HTTP response status code can be:

• 201 "Created" if score is stored or
• 422 "Unprocessable Entity" in case of errors with data.

In the last case the error messages are returned as response.
