This is a set of Django projects that provide free sample code to support the www.dj4e.com web site.

You can see some of the samples working at

Setting up a Virtual Environment on the Mac

Install virtualenv, if you use homebrew you can:

brew install virtualenv

Then checkout this repository:

cd ...wherever...
git clone https://github.com/csev/dj4e-samples.git
cd dj4e-samples
virtualenv .venv
source .venv/bin/activate
python --version
pip install -r requirements42.txt

python manage.py migrate
python manage.py createsuperuser --username dj4e-samples
# python manage.py changepassword dj4e-samples
# dj4e_nn_!

Running Locally on the Mac

If you have Django installed on your local computer you can test any of the sample applications by going into the folder and starting the server:

cd dj4e-samples
source .venv/bin/activate   # If needed
python manage.py runserver

And visit http://localhost:8000.

Setting up a Virtual Environment on Python Anywhere

The instructions for setting up a virtual environment on PythonAnywhere in the Linux shell are:

mkvirtualenv django4 --python=/usr/bin/python3.11
pip install django==4.2.3 ## this may take a couple of minutes

To activate the environment type:

workon django4

Then check this out into some folder:

cd ~/django_projects    # Create the folder if needed
git clone https://github.com/csev/dj4e-samples.git
cd dj4e-samples
pip install -r requirements.txt
python manage.py migrate
python manage.py createsuperuser --username dj4e-samples
# python manage.py changepassword dj4e-samples
# dj4e_nn_!
python manage.py runscript gview_load
python manage.py runscript many_load

These samples may be updated from time to time so you might want to get updates using git pull. Also if there are bugs, you are welcome to submit a Pull Request on github.

Running on PythonAnywhere

Once you have checked out the code under django_projects, and ran the migrations and load scripts, go under the Web tab, update the config files to point to your new application:

Source code:                /home/--your-account--/django_projects/dj4e-samples
Working Directory:          /home/--your-account--/django_projects/dj4e-samples

Use this as your WGSI configuration file:

import os
import sys

path = os.path.expanduser('~/django_projects/dj4e-samples')
if path not in sys.path:
    sys.path.insert(0, path)
os.environ['DJANGO_SETTINGS_MODULE'] = 'dj4e-samples.settings'
from django.core.wsgi import get_wsgi_application
from django.contrib.staticfiles.handlers import StaticFilesHandler
application = StaticFilesHandler(get_wsgi_application())

You can edit these files and settings in the Web tab to switch between your various projects on PythonAnywhere. Make sure to reload under the Web tab after every file or configuration change.
