This is a fairly typical and small rails project.

• database: sqlite3
• test framework: rspec

The project contains the following models:

• User
  • Represents an end-user identified by an email - tested
  • Has many wallets - tested
• Wallet
  • Contains a money balance (amount, currency) - tested
  • Belongs to a user - tested
• Transaction
  • A financial transaction performed by a user
  • Contains a money amount (amount, currency)
  • Described by an action (credit, debit)
  • Described by a category (deposit, withdraw, ante, purchase, refund)
  • Belongs to a user
  • Example: a credit transaction for a deposit that placed $5 USD into a user's wallet
• Financial Summary
  • A summary of count and amount of deposits, withdraws, refunds, antes, purchases for a given user and currency
  • A summary spans over one day, seven days and a lifetime of a user's transactions

Implement the logic for the FinancialSummary. There are pending specs that you should make pass. The specs are non-exhaustive (hint hint).

You will need:

• ruby 2.4.2
• bundler

Assuming you have ruby installed, install bundler:

$ gem install bundler

cd to the project dir and install dependencies:

$ bundle

Run specs:

$ bundle exec rspec

Push this entire project (with your changes) onto Github and send us the link to the repo.

This project does not expose the FinancialSummary as an API or html. If you want to expose it, then feel free. There is no "extra credit" for doing so. It would just another thing that we can discuss after submission.
