UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

How to seed a Rails database with a CSV file

1. Setup

First, Create a folder inside of lib called seeds

Put your CSV file example.csv into the lib/seeds folder. In the example below, the file is called real_estate_transactions.csv

Make sure you've created a resource with the appropriate columns to match your seed data. The names don't have to match up.

has_many :through

---

In this exercise we are going to explore the has_many through relationship by creating a quick example. The first part of this markdown will be geared toward making a simple example that shows the relationship while the second part will consist of expanding the simple app to show the relationships in the browser.

We are going to use doctors and patients for this example.

As you could have guessed a doctor can have many patients and a patient can have many doctors. One way that we could facilitate this many to many relationship is by using an "associative table". We can call our associative table "appointments", which should help us make it easier to understand the relationship between doctors and patient.
