From cf54df04169918bcf4a81eccd3f455c820e75f52 Mon Sep 17 00:00:00 2001 From: pacnpal <183241239+pacnpal@users.noreply.github.com> Date: Fri, 9 Jan 2026 08:04:44 -0500 Subject: [PATCH] fix(fsm): Fix StateLog.by capture and cycle validation; add photographer field to photos ## FSM State Machine Fixes ### StateLog.by Field Capture - Modified TransitionMethodFactory to pass 'user' as 'by' kwarg to enable django-fsm-log's @fsm_log_by decorator to correctly capture the user who performed the transition - Applied fix to both escalate_transition and create_transition_method - Uses exec() to dynamically create transition functions with correct __name__ before decorators are applied, ensuring django-fsm's method registration works ### Cycle Validation Behavior - Changed validate_no_cycles() to return ValidationWarning instead of ValidationError - Cycles are now treated as warnings, not blocking errors, since cycles are often intentional in operational status FSMs (e.g., reopening after temporary closure) ### Ride Status Transitions - Added TEMPORARY_CLOSURE -> OPERATING transition (reopen after temporary closure) - Added SBNO -> OPERATING transition (revival - ride returns to operation) ## Field Parity ### Photo Models - Added 'photographer' field to RidePhoto and ParkPhoto models - Maps to frontend 'photographer_credit' field for full schema parity - Includes corresponding migrations for both apps ### Serializers - Added 'photographer' to RidePhotoSerializer and ParkPhotoSerializer read_only_fields --- backend/apps/api/v1/parks/serializers.py | 3 + backend/apps/api/v1/rides/serializers.py | 3 + backend/apps/core/state_machine/decorators.py | 58 ++++++++++++++----- backend/apps/core/state_machine/validators.py | 31 +++++----- .../0031_add_photographer_to_photos.py | 41 +++++++++++++ backend/apps/parks/models/media.py | 5 ++ backend/apps/rides/choices.py | 2 + .../0039_add_photographer_to_photos.py | 41 +++++++++++++ backend/apps/rides/models/media.py | 5 ++ 9 files changed, 157 insertions(+), 32 deletions(-) create mode 100644 backend/apps/parks/migrations/0031_add_photographer_to_photos.py create mode 100644 backend/apps/rides/migrations/0039_add_photographer_to_photos.py diff --git a/backend/apps/api/v1/parks/serializers.py b/backend/apps/api/v1/parks/serializers.py index 99641f5a..f9c19ed2 100644 --- a/backend/apps/api/v1/parks/serializers.py +++ b/backend/apps/api/v1/parks/serializers.py @@ -113,6 +113,7 @@ class ParkPhotoOutputSerializer(serializers.ModelSerializer): "image_url", "image_variants", "caption", + "photographer", "alt_text", "is_primary", "is_approved", @@ -147,6 +148,7 @@ class ParkPhotoCreateInputSerializer(serializers.ModelSerializer): fields = [ "image", "caption", + "photographer", "alt_text", "is_primary", ] @@ -159,6 +161,7 @@ class ParkPhotoUpdateInputSerializer(serializers.ModelSerializer): model = ParkPhoto fields = [ "caption", + "photographer", "alt_text", "is_primary", ] diff --git a/backend/apps/api/v1/rides/serializers.py b/backend/apps/api/v1/rides/serializers.py index 0d640410..14206f0b 100644 --- a/backend/apps/api/v1/rides/serializers.py +++ b/backend/apps/api/v1/rides/serializers.py @@ -117,6 +117,7 @@ class RidePhotoOutputSerializer(serializers.ModelSerializer): "image_url", "image_variants", "caption", + "photographer", "alt_text", "is_primary", "is_approved", @@ -156,6 +157,7 @@ class RidePhotoCreateInputSerializer(serializers.ModelSerializer): fields = [ "image", "caption", + "photographer", "alt_text", "photo_type", "is_primary", @@ -169,6 +171,7 @@ class RidePhotoUpdateInputSerializer(serializers.ModelSerializer): model = RidePhoto fields = [ "caption", + "photographer", "alt_text", "photo_type", "is_primary", diff --git a/backend/apps/core/state_machine/decorators.py b/backend/apps/core/state_machine/decorators.py index 3408750c..c2005717 100644 --- a/backend/apps/core/state_machine/decorators.py +++ b/backend/apps/core/state_machine/decorators.py @@ -53,6 +53,11 @@ def with_callbacks( def wrapper(instance, *args, **kwargs): # Extract user from kwargs user = kwargs.get("user") + + # Pass user as 'by' for django-fsm-log's @fsm_log_by decorator + # This must be set before calling the inner func so the decorator can capture it + if user is not None and 'by' not in kwargs: + kwargs['by'] = user # Get source state before transition source_state = getattr(instance, field_name, None) @@ -329,6 +334,9 @@ class TransitionMethodFactory: ) def approve(instance, user=None, comment: str = "", **kwargs): """Approve and transition to approved state.""" + # Pass user as 'by' for django-fsm-log's @fsm_log_by decorator + if user is not None: + kwargs['by'] = user if hasattr(instance, "approved_by_id"): instance.approved_by = user if hasattr(instance, "approval_comment"): @@ -382,6 +390,9 @@ class TransitionMethodFactory: ) def reject(instance, user=None, reason: str = "", **kwargs): """Reject and transition to rejected state.""" + # Pass user as 'by' for django-fsm-log's @fsm_log_by decorator + if user is not None: + kwargs['by'] = user if hasattr(instance, "rejected_by_id"): instance.rejected_by = user if hasattr(instance, "rejection_reason"): @@ -435,6 +446,9 @@ class TransitionMethodFactory: ) def escalate(instance, user=None, reason: str = "", **kwargs): """Escalate to higher authority.""" + # Pass user as 'by' for django-fsm-log's @fsm_log_by decorator + if user is not None: + kwargs['by'] = user if hasattr(instance, "escalated_by_id"): instance.escalated_by = user if hasattr(instance, "escalation_reason"): @@ -483,31 +497,45 @@ class TransitionMethodFactory: # Get field name for callback wrapper field_name = field.name if hasattr(field, 'name') else 'status' -
