The task is to implement following Rails application.
The app should fetch and display currency conversion rates. To get rates you need to use the free API: fixer.io
The app consists of two pages: first one is currency conversion rates, the other one is a management page.
Display all conversion rates in format:
| Currency 1 | Currency 2 | Rate |
|---|---|---|
| USD | EUR | 0.922 |
| PLN | CZK | 6.204 |
Below, display a link or button that will redirect to page 2.
Allow to add conversion pairs like:
[USD] [EUR] [+]
where [USD], [EUR] are selects letting you pick conversion pair, and [+] is a button saving it.
Below, list all added conversion pairs and allow the user to remove them with click of a link or a button.
- Conversion rates should be saved in the database and refreshed with Rake task. It cannot be fetched in time of loading Page 1.
- Conversion pairs should also be saved in the database.
- You can use any DB engine you want (SQLite, MySQL, Postgres…).
- Use newest stable Rails version.
- Use TDD.
- Don’t worry too much about front-end but if you want to make a good impression you can use something like Bootstrap.
- Make sure README includes all required steps to run your app on Unix-like environment. We’ll do our best to run your app on our computers, but if you use something non-standard you should let us know about it.
Take your time but try to deliver it within 2 weeks time. If we don't see any activity in your test repository after 2 weeks (at least initial commits), we will automatically withdraw your application.
