commit ab0d1ae0dbcb5e918c5d24092a2fd9c0367967bc Author: grabowski Date: Tue Oct 28 16:31:48 2025 +0700 Initial commit: InvenTree Stock Tool v2 A comprehensive barcode scanning application for InvenTree inventory management. Features: - Multi-mode operation (Add/Update/Check/Locate stock) - Smart duplicate prevention when adding stock - Barcode scanning with automatic part code cleaning - Real-time server connection monitoring - Part information display with images - Debug mode for troubleshooting Fixes applied: - Fixed encoding issues with non-ASCII characters in barcodes - Fixed API response handling for list and dict formats - Implemented duplicate prevention using PATCH to update existing stock - Added comprehensive error handling and logging Includes test suite for verification of all fixes. diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..f406626 --- /dev/null +++ b/.gitignore @@ -0,0 +1,53 @@ +# Python +__pycache__/ +*.py[cod] +*$py.class +*.so +.Python +build/ +develop-eggs/ +dist/ +downloads/ +eggs/ +.eggs/ +lib/ +lib64/ +parts/ +sdist/ +var/ +wheels/ +*.egg-info/ +.installed.cfg +*.egg +MANIFEST + +# Virtual Environment +venv/ +env/ +ENV/ +env.bak/ +venv.bak/ + +# IDE +.vscode/ +.idea/ +*.swp +*.swo +*~ +.DS_Store + +# Configuration files (may contain sensitive data) +*.yaml +*.yml +!example_config.yaml + +# Logs +*.log + +# Test files (optional - uncomment if you don't want to track tests) +# test_*.py + +# Temporary files +*.tmp +*.bak +*.cache diff --git a/FIXES_APPLIED.md b/FIXES_APPLIED.md new file mode 100644 index 0000000..2d1a8d0 --- /dev/null +++ b/FIXES_APPLIED.md @@ -0,0 +1,196 @@ +# Stock Tool GUI v2 - Fixes Applied + +## Summary +Fixed three critical issues in `stock_tool_gui_v2.py`: +1. ✅ Encoding issue with barcode part numbers +2. ✅ API response handling causing "'list' object has no attribute 'get'" errors +3. ✅ Duplicate stock items being created when adding to existing location + +--- + +## Issue 1: Encoding Problem with Part Numbers + +### Problem +Raw scan data contained: `pm:STHW4-DU-HS24041¡­` +The non-ASCII characters (¡­) were being included in the parsed part number. + +### Root Cause +The `parse_scan()` function was not cleaning/sanitizing the extracted part codes. + +### Fix Applied +Added `clean_part_code()` helper function that: +- Filters out all non-ASCII characters +- Keeps only printable ASCII characters (codes 32-126) +- Removes encoding artifacts like `¡­` + +### Location +File: `stock_tool_gui_v2.py` +Function: `parse_scan()` (lines 294-348) + +### Result +- **Before**: `STHW4-DU-HS24041¡­` +- **After**: `STHW4-DU-HS24041` ✓ + +--- + +## Issue 2: API Response Handling Error + +### Problem +Error: `'list' object has no attribute 'get'` +- Stock not being added to InvenTree +- Stock levels not updating after adding items + +### Root Cause +The InvenTree API POST response can return either: +- A dictionary: `{'pk': 123, 'quantity': 150, ...}` +- A list: `[{'pk': 123, 'quantity': 150, ...}]` + +The code was assuming it would always be a dict and calling `.get()` directly on the response, which failed when the API returned a list. + +### Locations with the Bug +1. `_add_stock()` function - line 806 (original) +2. `_update_stock()` function - line 865 (original) +3.
