PRs with code snippets

The "code snippet" label can be used to identify and search for pull requests that have code snippets.

RapidPro snippets

• Migrating a custom field from RapidPro to a Django model - See the comment in #925.
• Finding users dropped by follow-up campaigns - See #919.
• Determining when a RapidPro contact was added to a contact group - Work on this was done in #902 but the code was never merged because it wasn't needed more than once.

Deleting all DocuSign envelopes

This is especially useful when working on the DocuSign envelope generation code: because we actually cache envelopes, it one actually has to re-generate PDF forms to generate a new envelope, which can be a bit of a pain, so going into python manage.py shell and deleting all envelopes from your development database can be useful:

from hpaction.models import DocusignEnvelope; DocusignEnvelope.objects.all().delete()

Finding users in a WoW portfolio

To find users in a portfolio that's rooted in a BBL (using Who Owns What's algorithm), see #944.

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
)

Conversely, here's a query for users who didn't self-report as NYCHA but are actually in a NYCHA BBL:

SELECT onb.user_id, onb.lease_type
FROM onboarding_onboardinginfo as onb
WHERE onb.lease_type <> 'NYCHA' AND onb.pad_bbl <> '' AND onb.pad_bbl 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;
