Enable the equivalent of ./manage.py shell_plus under PyCharm's Django Console.

shell_plus_for_pycharm_django_console.py

# Confirmed working under:
# -   Python3.7 / Django 2.2 / Django Extensions / IPython Available
# -   Python3.7 / Django 2.2 / Django Extensions / IPython Unavailable
# 
# Notices:
# -   This might even work in PyCharm CE with the python console, but no guarantees there.
# -   There are no language features required that shouldn't be available as far back as python2.6, maybe 2.5.
# -   There are no framework features required that shouldn't be available as far back as Django 1.7
# -   Should still provide basic Django shell when Django Extensions is unavailable.
# -   This is for all of my friends to enjoy!   
#
# Installation:
# 1.  PyCharm -> Preferences
# 2.  Build, Execution, Deployment -> Console -> Django Console
# 3.  Settings:
#     -   Project: Your Django Project
#     -   Python Interpreter: Your Django Project's VirtualEnv
#     -   Environment Variables, Interpreter Options, Working Directory: {NONE}
#     -   [x] Add content roots to PYTHONPATH, Add source roots to PYTHONPATH
#     -   Starting Script: {THE ENTIRE CONTENTS OF THIS FILE}
# 4.  Tools -> Python Console
# 5.  Enjoy!
