Deploying a Production ready Django app on AWS

In this tutorial, I will be going over to how to deploy a Django app from start to finish using AWS and EC2. Recently, my partner Tu and I launched our app Hygge Homes (a vacation home rental app for searching and booking vacation homes based off Airbnb) and we wanted to share with other developers some of the lessons we learned along the way.

Following this tutorial, you will have an application that has:

• An AWS EC2 server configured to host your application
• SSL-certification with Certbot
• A custom domain name
• Continuous deployment with Github Actions/SSM Agent

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

   Just add two spaces at the end of the line. It worked for me. :)
2. BEGIN in Ruby.

Explaining require and permit: params.require(:person).permit(:name, :age)

The params in a controller looks like a Hash, but it's actually an instance of ActionController::Parameters, which provides several methods such as require and permit.

The require method ensures that a specific parameter is present, and if it's not provided, the require method throws an error. It returns an instance of ActionController::Parameters for the key passed into require.
