Test this branch locally in a dev container

0. In local file mode, check out the branch: pyup-update-django-3.2.6-3.2.7
1. Open the localhost directory - cd localhost
2. Build the new container (with the new version of Django) by runningdocker-compose build --no-cache client
3. Click Rebuild and Reopen in Remote Container
4. Confirm django version by running: python manage.py version - This command should return the version specified in the pull request, 3.2.7
5. Run the app in debug mode by clicking F5 or going to the Debug sidebar in VS Code and clicking Play. (*In Mac, may require making sure the Python debugger VS Code extension is turned on)

Notes:

• Using the Remote Container with this PR, in Open in Container mode, may use the cached build, which won't have the new Django library.
• Using the Remote Container with this PR in Build Without Cache mode, without having first gone through step 3, will result in a "Container not found" error.
