Couchsurfing Rails Challenge

Setup

• Fork this repository
• Make sure that Ruby, Rails, and SQLite3 are installed on your machine. This might be helpful if you don't create new apps everyday https://guides.rubyonrails.org/getting_started.html
• Run bundle install to install gems
• Setup database rake db:setup
• Run the app rails server or an interactive console rails console to test that your app is running.

Premise:

• E-commerce sites often follow a similar data format. I've already created models for some of the more common resources. These are the objects that are already modeled and included in the schema.

• A customer is someone making a purchase.
• A product is a product for sale.
• A variant is a version of a specific product. For example if the product was "Jean Jacket" the variants might be "Dark Blue" and "Light Blue", although variant usage is not limited to color.
• A collection contains a group of similar products

Note:

• Please use RSpec for the test, but otherwise use any libraries you prefer.
• We encourage writing the tests first! If you are comfortable with TDD, do Step 3 before Step 2.
• Please make frequent commits (the more the commits, the easier for us to review coding patterns)

We evaluate the code based on the following criteria:

• Strong database design and modelling
• Good REST API practices
• Good usage of model level constraints, validations, etc
• Good coding practices, we follow https://github.com/rubocop-hq/ruby-style-guide as far as possible at Floh
• Test cases (rspec or other) for controller and model methods

Step 1

Create a model for a customer order.

It should store these attributes.

• Date created
• Reference/relationship to the customer who is placing the order.
• Reference to each variant ordered and the quantity ordered of each variant. (HINT: Might be helpful to create a second model here)
• Total cost of all variants included in the order. (Should not change when the price of an included variant is changed)
• Current order status ['pending', 'processing', 'fulfilled', 'delivered', 'canceled']. This field should default to pending.

Step 2

Create an endpoint to create orders. This endpoint enables the creation of an order based on a set of required parameters(customer_id, list of variant_ids and quantities ordered)

Requirements

• Creating an order returns a 400 response if the request doesn't contain required parameters
• Creating an order returns a 404 response if any of the customer or variant ids are invalid.
• Creating an order returns a 422 response if there is not enough stock for any of the variants contained in the order.
• Creating an order succeeds if none of the previous error scenarios occur.

Step 3

Write an RSpec test to verify that order creation endpoint behaves as described above.

Step 4

Create an endpoint to display a single order resource at the /orders/{#id}.json endpoint.

• Response should contain all order fields, and additionally include variant id, name, price, and quantity ordered for each variant included in the order.

Step 5

Create a front-end using any of the popular front-end frameworks (React, Angular, Vue, etc.). Front-end should allow the user to create orders, view all orders, and change order status.
