Rails Programming Task

In order to be considered for a Rails position, you must complete the following steps.

Note: This task should take no longer than 1-2 hours at the most to complete.

Prerequisites

Task

  • Fork this repository (if you don't know how to do that, Google is your friend).
  • Create a source directory.
  • In the source directory, scaffold a simple Rails 4 web app that models a credit card charge. JSON data structure below:
  {
    "id": 9923,
    "created": 1389618241,
    "paid": true,
    "amount": 4900,
    "currency": "usd",
    "refunded": false,
    "customer_id" : 123
  }

*Note: Amount is in USD, cents*
  • Also scaffold a customer object which only has a first and last name.

The charge object has a customer property, this property is the customer id from the customer model.

Seed 4 Customers into the system:
Customer 1: 
  First Name: Johny 
  Last Name: Flow

Customer 2: 
  First Name: Raj
  Last Name: Jamnis

Customer 3: 
  First Name: Andrew
  Last Name: Chung

Customer 4: 
  First Name: Mike
  Last Name: Smith
Seed 20 transactions (charges) into the system:
10 Should be successful transactions:
  - 5 Should be linked to Customer 1
  - 3 Should be linked to Customer 2
  - 1 Should be linked to Customer 3
  - 1 Should be linked to Customer 4

5 Should be transactions that failed:
  - 3 Should be linked to Customer 3
  - 2 Should be linked to Customer 4

5 should be disputed:
  - 3 should be linked to Customer 1
  - 2 should be linked to customer 2
Create a Visual Representation of Different Charges:

On the view that shows all charges (most likely the GET /charges route), create three lists with H1 headers.

  • List 1 -

    • Header: Failed Charges
    • In this list set the background color of the rows to #FF0000 and list the Customers name, the charge amount and the date that the charge failed for each failed charge.

  • List 2 -

    • Header: Disputed Charges
    • In this list set the background color of the rows to ##FF5400 and list the Customers name, the charge amount and the date that the charge was disputed for each disputed charge.

  • List 3 -

    • Header: Successful Charges
    • In this list simply display all the charges that were succesful.

Tests

Create the following RSpec tests:

  1. Verify that there are three lists on the screen. One for successful charges, one for failed charges and one for the disputed charges.
  2. Verify that in the Successful charges list there are 10 line items. Verify that in the failed charges list there are 5 failed charges. Verify that in the disputed charges list there are failed charges.
