216-226: Push dedup/filter work to the database to reduce Python memory churn.

set(...) materialization here works, but this can be done with DB-level distinct() and subquery composition, which scales better for larger org/subscription tables.

Refactor sketch

-            active_org_id_strings = set(
-                Subscription.objects.filter(is_active=True).values_list(
-                    "organization_id", flat=True

-            )
-            # Map org_* strings back to Organization PKs
-            all_org_ids = set(
-                Organization.objects.filter(
-                    organization_id__in=active_org_id_strings
-                ).values_list("id", flat=True)

lines 216 - 226, The current code materializes Subscription and Organization IDs
into Python sets (active_org_id_strings and all_org_ids) which causes
unnecessary memory churn; instead push deduping to the DB by using
QuerySet.distinct() and subquery composition: get the distinct subscription
organization_id via
Subscription.objects.filter(is_active=True).values_list("organization_id",
flat=True).distinct() (or wrap as a Subquery), then use that QuerySet/Subquery
in Organization.objects.filter(organization_id__in=...) to fetch Organization
IDs (and call .values_list("id", flat=True).distinct()) so no large set(...)
materialization is done in Python and the database handles deduplication.

207-210: ⚠️ Potential issue | 🟡 Minor

Catch ValidationError for malformed --org-id.

This lookup can still raise django.core.exceptions.ValidationError (commonly with malformed UUID input), so the command may abort before reaching the friendly “not found” path.

Patch suggestion

+from django.core.exceptions import ValidationError
...
         if org_id:
             try:
                 org = Organization.objects.filter(id=org_id).first()
-            except (ValueError, TypeError):
+            except (ValueError, TypeError, ValidationError):
                 org = None

#!/bin/bash
set -euo pipefail

# Verify Organization PK type and current exception handling
fd "models.py" | xargs rg -n --type=py -C3 "class Organization\\(|id\\s*=\\s*models\\.(UUIDField|AutoField|BigAutoField|IntegerField)"
rg -n --type=py -C3 "_resolve_org_ids|except \\(ValueError, TypeError\\)|ValidationError" backend/dashboard_metrics/management/commands/backfill_metrics.py

Expected result: if Organization.id is a UUIDField, ValidationError should be handled in this branch.

Organization.objects.filter(id=org_id).first() only catches ValueError and
TypeError but a malformed UUID can raise django.core.exceptions.ValidationError;
update the exception handling in the block that resolves org_id (the call
performing Organization.objects.filter(id=org_id).first()) to also catch
ValidationError (imported as from django.core.exceptions import ValidationError)
so malformed UUID inputs fall back to org = None and proceed to the existing
“not found” handling.

71-75: Clarify --org-id help text to indicate PK semantics.

The current text is ambiguous with Organization.organization_id also in play. Explicitly stating “Organization.id (PK)” will reduce operator confusion.

             "--org-id",

             default=None,

lines 71 - 75, Update the help string for the "--org-id" argument in the
management command (inside add_arguments of Command in backfill_metrics.py) to
explicitly state that it expects the Organization primary key; replace the
ambiguous text "Specific organization ID to backfill (default: all orgs)" with
something like "Specific Organization.id (primary key) to backfill; if omitted,
backfills all organizations" so operators know to supply the PK rather than
Organization.organization_id.

142-145: Optional: include org display name in progress output.

For long backfills, printing <org_id> (<name>) makes operator monitoring much easier.

lines 142 - 145, Update the progress print in the backfill loop to include the
org display name alongside the org id: inside the loop over org_ids (variables
org_ids, current_org_id, i) fetch the Organization display name (e.g., via the
Organization model or existing lookup used elsewhere in backfill_metrics.py) and
change the self.stdout.write call to print "{org_id} ({display_name})" with a
safe fallback to the id if the name is missing; ensure you reference
org_ids/current_org_id and self.stdout.write when making the change so it works
for long-running backfills.
