From cf10103895d1b6f882bb3e15f09cb23a7a5cd524 Mon Sep 17 00:00:00 2001 From: RohanExploit <178623867+RohanExploit@users.noreply.github.com> Date: Wed, 25 Feb 2026 11:27:13 +0000 Subject: [PATCH 1/4] Refactor data models to use native JSON type and improve API robustness - Replace custom `JSONEncodedDict` with `sqlalchemy.types.JSON` in `backend/models.py` to enable native JSON storage (e.g., JSONB in Postgres). - Fix `get_recent_issues` in `backend/routers/issues.py` to return consistent data types (list of dicts) when serving from cache, avoiding `JSONResponse` wrapper issues. - Add robust file cleanup in `create_issue` in `backend/routers/issues.py` using `try...finally` to ensure uploaded images are deleted if the issue is a duplicate or DB save fails. - Refactor `process_uploaded_image_sync` in `backend/utils.py` to reuse validation logic and remove code duplication. - Add `backend/tests/test_optimizations.py` to verify the fixes. --- backend/models.py | 25 +---- backend/routers/issues.py | 10 +- backend/tests/test_optimizations.py | 147 ++++++++++++++++++++++++++++ backend/utils.py | 54 +++------- 4 files changed, 171 insertions(+), 65 deletions(-) create mode 100644 backend/tests/test_optimizations.py diff --git a/backend/models.py b/backend/models.py index 07149e5e..ec79bc4c 100644 --- a/backend/models.py +++ b/backend/models.py @@ -1,27 +1,10 @@ -import json -from sqlalchemy import Column, Integer, String, DateTime, Float, Text, ForeignKey, Enum, Index, Boolean -from sqlalchemy.types import TypeDecorator +from sqlalchemy import Column, Integer, String, DateTime, Float, Text, ForeignKey, Enum, Index, Boolean, JSON from backend.database import Base from sqlalchemy.orm import relationship import datetime import enum -class JSONEncodedDict(TypeDecorator): -
