Caching derived data for onboarding

#401 contained a snippet we can run when we add a new derived data field for onboarding:

import os

if __name__ == '__main__':
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')

    import django
    django.setup()

    from onboarding.models import OnboardingInfo

    for info in OnboardingInfo.objects.filter(pad_bbl=''):
        print(f"Updating address metadata for {info.user}.")
        info.save()

Listing users who reported as NYCHA but don't live in NYCHA housing

SELECT onb.user_id
FROM onboarding_onboardinginfo as onb
WHERE onb.lease_type = 'NYCHA' AND onb.pad_bbl <> '' AND onb.pad_bbl NOT IN (
    SELECT pad_bbl from nycha_nychaproperty
)

Listing users who have logged in since sending their letter of complaint

SELECT u.username, u.last_login, lr.created_at
FROM users_justfixuser AS u, loc_letterrequest AS lr
WHERE u.id = lr.user_id AND u.last_login > lr.created_at;
