1. Debug template from views.py

import web_pdb;

class SipNoteUpdateView(LoginRequiredMixin, UpdateView):
    model = SipNote
    fields = ['note', 'note_date', 'at_devices',  'independent_living', 'orientation', 'communications', 'dls',
              'support', 'advocacy', 'counseling', 'information', 'services', 'retreat', 'in_home', 'seminar',
              'modesto', 'group', 'community', 'class_hours', 'sip_plan', 'instructor']
    template_name_suffix = '_edit'

    def dispatch(self, request, *args, **kwargs):
        # web_pdb.set_trace()  # Add this line to trigger the debugger
        return super().dispatch(request, *args, **kwargs)

    def get(self, request, *args, **kwargs):
        # web_pdb.set_trace()  # Add this line to trigger the debugger
        return super().get(request, *args, **kwargs)

2. Migrate from prod to dev

PROD:

pg_dump --exclude-table="account_*" $(get_db_settings 'NAME') > dump.sql

(Why the --exclude flag? See README's TODOs about django-user-accounts.)

DEV:

1. scp the dump.sql file from PROD to DEV
2. just db
3. just c -f dump.sql
4. just c --command="ANALYZE"
5. just deps
6. just m migrate (or just m migrate --fake-initial)
7. just prep
8. just serve

One-liner:

just db && just c  -f dump.sql && just c --command="ANALYZE" && just deps && just migrate && just prep && just serve

Serving with gunicorn:

just gunicorn 8000

Use --reload when developing:

just gunicorn 8000 --reload
