Description:

Simple e-Wallet application, developed with Ruby on Rails, deployed to a Heroku live server.

The objective of this exercise is to evaluate the analysis capacity, architecture definition and development practices that a candidate has.

Prerequisites

Software	Version
PostgreSQL	9.5.14
Ruby	2.5.1
Rails	5.2.1

Instructions:

1. Clone repository

# using ssh
$ git clone git@github.com:Memije/eWallet.git

# using https
$ git clone https://github.com/Memije/eWallet.git

2. Change working directory

$ cd eWallet

3. Install dependencies

$ bundle install

4. Initialize Figaro gem

bundle exec Figaro install

5. Configure the following environment variables in config/application.yml

Key	Description
pg_username	PostgreSQL username
pg_password	PostgreSQL password
KEY	256bit (32bytes) secret key

NOTE: It's important to keep it up to 32 bytes due to OpenSSL's truncation to 32 bytes. You can generate a secure key here.

Example:

# config/application.yml
db_username: 'cleverusername'
db_password: 'cleverpassword'
KEY: "kYp3s6v9y$B&E)H+MbQeThWmZq4t7w!z"

6. Create, migrate and seed database

$ rake db:create db:migrate db:seed

7. Run server

$ rails s

8. ???
9. PROFIT!!!

Tests
