Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

Guide on how to create and set up a Dockerized web app using Django REST APIs and ReactJS

Hopefully this will answer "How do I setup or start a Django project using REST Framework and ReactJS?"

This is a guide to show you step by step how this can be setup. If you just want to get started, use the cookiecuter I set up cookiecutter-django-reactjs. It basically is a fork of pydanny's cookiecutter, just added the front-end stuff :).

I created this because it was SUCH a pain in the ass setting up a project using all the latest technologies. After some research, I figured it out and have it working. The repo that implements this is located here. Feel free to use it as a boilerplate ;)

Main features:

Django REST APIs

Deploy Fathom on Heroku

Requirements

heroku cli (logged in)
git
curl
wget
tar are required
~ openssl is required to generate the secret_key, but you're free to use what you want

	To change a field name in django 1.7+

	1. Edit the field name in the model (but remember the old field name: you need it for step 3!)
	2. Create an empty migration
	$ python manage.py makemigrations --empty myApp
	3. Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

	migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

	to the operations list.
