Bash Script:

Make sure you have installed Python 3.9.0

To manage multiple Python installation use pyenv or pyenv-win (for windows). Then, pipenv should be able to automatically install required python.

pip install --upgrade pip
pip install pipenv
pipenv install --python 3.9
pipenv run install-client

For CentOS and other cloud servers that only support psycopg2-binary, use this instead:

pipenv run install-server

Setup Postgresql or any desired Django supported database.

Create .env file using .env.example and provide environment variables as required.

database_settings.py needs to be updated as per your database setup (or use DATABASE_URL in .env file)

pipenv run python manage.py migrate
pipenv run python manage.py createsuperuser

Running Tests:

pipenv run python manage.py test --debug-mode --debug-sql --parallel --buffer

OR simply run without any flags:

pipenv run python manage.py test

How to Bump Application Version?

Click to view

We use SemVer scheme to manage the version number. We have created a Django Command to upgrade the version in the settings file.

Command Usage:

• pipenv run python manage.py bump → Updates to Next Patch
• pipenv run python manage.py bump --to=2.2.2 → Updates Version Number to 2.2.2
• pipenv run python manage.py bump --type=major → Updates to Next Major
• pipenv run python manage.py bump --type=minor → Updates to Next Minor
• pipenv run python manage.py bump --type=patch → Updates to Next Patch

Releases and Tags can then be created accordingly.

If Static Files that does not exist e.g. https://example.com/static/bad-directory keeps throwing unhandled error use this temporary fix:

Inside env/lib/python3.7/site-packages/django/core/handlers/base.py find get_response without leading underscore and change it to as below:

from django.shortcuts import render

def get_response(self, request):
    """Return an HttpResponse object for the given HttpRequest."""
    # Setup default url resolver for this thread
    set_urlconf(settings.ROOT_URLCONF)
    try:
        response = self._middleware_chain(request)

        response._closable_objects.append(request)

        # If the exception handler returns a TemplateResponse that has not
        # been rendered, force it to be rendered.
        if not getattr(response, 'is_rendered', True) and callable(getattr(response, 'render', None)):
            response = response.render()

        if response.status_code == 404:
            logger.warning(
                'Not Found: %s', request.path,
                extra={'status_code': 404, 'request': request},
            )

        return response
    except:
        return render(request, '404.html', status=404)
