🎯 Project: Habit Tracker

You’ll be working on Habit Tracker this week.

It’s important to read the project requirements thoroughly and to start to think about how you would do this project.

First steps: generate the project skeleton; make sure you are using Postgres; deploy to Heroku; and design your models. Make sure to create a diagram showing model fields and relationships. Talk through with each other how you are thinking about this.

By tomorrow:

• Your application should be deployed to Heroku.
• Your models should be functional.
• You should be able to create habits and associated daily records in the Django shell (I recommend using shell_plus which is available when you have django-extensions installed).
