You are working at a kopi roastery. Create a rails app that tracks kopis.
Use this rails new command so that you can create an app inside this repo: (you must already be cd'd inside this repo)
rails _5.2.3_ new . -d postgresql --skip-turbolinks --skip--coffee --skip-git
Each individual kopi has a name and roastedness (roast), and is associtaed with an origin (farm where it comes from).
A kopi farm (origin) has a location, phone number and is associated with many kopis.
Migrate your app to track roastedness in a separate table. Use the seed.rb file to put the 7 kinds of roast into the DB.
Each kopi will have a roast.
A roast will have many kopis.
Using your models will look something like this:
# get all kopis that are Italian roast
Roast.find_by(name: "Italian").kopis
Change your db model to include an order for a kopi. Change your kopi table to track price per pound. Add an order model. A kopi order has a weight. It is associated with a kopi.
For the routes /orders and /orders/:id include the total price of each order. (weight * price per pound)
Create a /report route that will display sales data.
In order to have data to display you should add more kopis and orders into your database from a seed file.
/report should display the total sales for that day.
Change /report to also display sales by kopi.
Change /report to also display sales by origin.
