envsource

I've been using Fish shell for years which is great and all, but one thing that has got me frustrated is using it with .env files.

When attempting to run source .env in a project, I usually encounter this problem:

.env (line 2): Unsupported use of '='. In fish, please use 'set KEY value'.
from sourcing file .env
source: Error while reading file '.env'

Django for Jupyter

It's true packages exist to make it "easy" to use Django inside of a jupyter notebook. I seem to always run into issues successfully running these packages. I've found the below method useful although I cannot recall how I discovered how this works (aka attribution needed).

Requirements

• Virtual Environment (virtualenv, venv, pipenv, etc)
• Django installed & project created (we'll use the project name cfehome)
• Jupyter installed at least in the virtual environment
