README

I have chosen to implement this solution under the form of an API in order to maintain a certain flexibilty and changeability for the future. Possible scenarios would be additing and endpoint for expanding the list of registered products or updating the details of existing ones.

Setup instructions

After cloning the project locally, you will need to navigate to the project folder and run the following:

• bundle install
• rake db:create
• rake db:migrate
• rake db:seed
• rails s to get a local server running and listening on http://127.0.0.1:3000

Usage instructions using cURL

curl -X GET "http://127.0.0.1:3000/api/v1/products/total_price" -d "items[]=GR1&items[]=GR1"

{"total":"3.11€"}

curl -X GET "http://127.0.0.1:3000/api/v1/products/total_price" -d "items[]=SR1&items[]=SR1&items[]=GR1&items[]=SR1"

{"total":"16.61€"}

curl -X GET "http://127.0.0.1:3000/api/v1/products/total_price" -d "items[]=GR1&items[]=CF1&items[]=SR1&items[]=CF1&items[]=CF1"
