Acme-Service

Challenge

The acme-service is a simple service that provides a REST API to manage a list of products. The service is written in Elixir, uses the Phoenix framework, and a Postgres database. In this challenge, you will be asked to add a new feature to the service. The new feature is an endpoint that computes the total inventory cost of a product. The total inventory cost should be calculated by simply multiplying the prodcut's unit cost by the quantity. Below is a sample of the expected request/response.

Request

GET /products/:id/total_inventory_cost

Response

{
    "data": {
        "id": 1,
        "category": "some category",
        "unit_cost": 20,
        "description": "some description",
        "name": "some name",
        "quantity": 10,
        "total_inventory_cost": 200
    }
}

Test

The test below should pass when the feature is implemented correctly.

Getting Started

To start your Phoenix server:

  • Install dependencies with mix deps.get
  • Create and migrate your database with mix ecto.setup
  • Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.
