Today we’ll begin our first shared project. This will require more planning, a lot of communication and coordination, and adding on some new git skills that will let us collaborate.

Project: Django Duplex

You will work in a shared repo for this and turn in one application that your team will build together. How you share the work is up to you.

Teams:

• Rajee & Blake: Team Honey Badger
• Tyler & Joey: Team Pine Marten
• Russell & Shelby: Team Sea Otter

Resources

• GitHub Collaboration Docs
• Git in VS Code -> I use git on the command line and that’s how I teach people to use it. But you might like using the integration in VS Code. This is a good place to start, but there are many other extensions that you could use as well.
• Pair Programming Guide -> This template for a pairing session is practical and actionable. There are other resources on this site worth a look as well.
• Django cheat sheet -> This is the same one I posted earlier in the week. If you didn’t see it then, you might be glad to see it now.
• Django Project Template -> This template will give you a django project structured like the same ones you’ve been working with. You’ll still need to run startaapp to set up your app.

You’ve now seen how to handle data in a Django application with basic operations in these categories:

• Create - when we add a new model instance to the database
• Read - when we query the database to look up existing data
• Update - when we query the database to find existing data so we can change it
• Destroy - when we query the database to find data that we want to delete

At the heart of many web applications you’ll find variations on this theme, so we’ll continue to practice it.

Today we’ll add in another essential part of web applications: user registration and login.

Resources

• Momentum Django project template
• django-registration-redux
• Python dependency management overview - good read to understand pip and poetry better
• Django docs: Authentication in Web Requests -> django-registation-redux handles some of this for us (giving us the login and logout urls, for instance) but it’s helpful to see other ways you can use the authenticated user.

💥 Django Cheatsheet!

This is a handy reference.
