Authentication

This guide provides a step-by-step on how I set up the user authentication for this dashboard, which was based on these tutorials:

How to set up user authentication

1. If not already in environment, install django (add to requirements.txt, recreate environment)

2. Create a Django app. In terminal:

   • django-admin startproject config .

   This produced a config folder containing 5 .py files.

3. Create a superuser to manage all other users:

   • python3 manage.py migrate

   • python3 manage.py createsuperuser

   Then enter user as kailobeewell and the dartington email address. I have record of password personally which I can share with other team members.

4. Start the server: python3 manage.py runserver.

5. Open web-browser and go to http://localhost:8000/admin/. Login with the superuser username and password just created.

6. Add some users by clicking ‘+ Add’ next to Users, then entering a username and password for each user. For the synthetic dashboard, I create some basic logins (which need to be more secure for actual dashboard). For each user followed the format of:

   • Username: schoola

   • Password: schoolapassword

7. Created the authentication.py script (see utilities folder)

8. On each of the app pages, imported the check_password() function from authentication.py, then sat all the page code under it, eg:

import streatmlit as st
from utilities.authentication import check_password

if check_password():
    st.title('Page title')
    st.write('Page content)
    ...

The actions above (migrate, superuser, adding users) will have generated and modified a db.sqlite3. Make sure you push this up to GitHub repository - I found that the app failed on deployment without it.
