# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [1.0.14] - 2025-11-24

### Changed
- Removed debug logging from EntityManager

## [1.0.13] - 2025-11-24

### Fixed
- Fixed UPDATE operations not updating data - now only updates fields explicitly provided
- Added `fieldsToUpdate` parameter to `persist()` and `save()` methods for partial updates
- Fixed SQL quoting in UPDATE statements (added backticks around table and column names)

### Changed
- `Repository.save()` and `EntityManager.persist()` now accept optional `fieldsToUpdate` parameter
- When `fieldsToUpdate` is provided, only those fields are updated in the database

## [1.0.12] - 2025-11-24

### Fixed
- Fixed UPDATE operations being treated as INSERT - now correctly detects when entity has an ID
- Fixed duplicate entry error on UPDATE - entities with AUTO_INCREMENT IDs now properly update instead of inserting

## [1.0.11] - 2025-11-24

### Fixed
- Simplified undefined field filtering - now only includes fields explicitly provided in request
- Database defaults are now handled by MySQL instead of being included in INSERT statements

## [1.0.10] - 2025-11-24

### Fixed
- Fixed syntax error in SpringApplication route handler
- Fixed EntityManager to skip undefined fields - only includes fields that are actually provided in the request
- Fixed UPDATE statements to only update fields that are explicitly set (not undefined)
- Fixed INSERT statements to only include fields that are provided or have default values

### Changed
- EntityManager now intelligently filters columns based on what's actually set on the entity
- UPDATE operations only modify fields that are explicitly provided
- INSERT operations skip undefined fields (unless they have database defaults)

## [1.0.9] - 2025-11-24

### Fixed
- Fixed SQL syntax error in INSERT statements - removed invalid multiple statement syntax
- Fixed AUTO_INCREMENT ID column being included in INSERT statements - now properly excluded
- Fixed LAST_INSERT_ID() retrieval - now uses result.insertId instead of separate SELECT query
- Improved INSERT statement generation to exclude ID column when AUTO_INCREMENT is used

## [1.0.8] - 2025-11-24

### Fixed
- Fixed POST/PUT/PATCH request body parsing - routes now correctly receive request body data
- Fixed route path normalization for all HTTP methods (GET, POST, PUT, DELETE, PATCH)
- Fixed empty route path handling (`''` paths) - now properly normalized
- Fixed null response handling - GET requests returning null now return 404 status
- Fixed trailing slash handling in route paths
- Fixed MySQL bind parameter error - undefined values are now converted to null for MySQL compatibility
- Fixed EntityManager to handle undefined entity properties correctly
- Fixed QueryBuilder to convert undefined parameters to null in WHERE clauses

### Changed
- Improved body parser configuration with 10mb limit for large payloads
- Enhanced route registration with better path normalization
- Added comprehensive route registration logging for debugging
- Improved error handling and logging for request body parsing issues
- Better error messages for debugging route and handler issues

### Added
- Route registration logging to help debug route setup issues
- Body parsing warnings when request body is empty
- Handler error logging for better debugging

## [1.0.7] - 2025-11-24

### Fixed
- Fixed SQL schema generation for ENUM and SET types - now correctly includes enum values
- Fixed DEFAULT CURRENT_TIMESTAMP handling - removed quotes for proper MySQL syntax
- Fixed Column decorator to store all ColumnOptions properties (enum, unsigned, onUpdate, etc.)
- Fixed route handler parameter metadata retrieval - now correctly reads from class prototype instead of instance
- Fixed TypeScript parameter decorators (@RequestParam, @PathVariable, @RequestBody) not working in controllers

### Changed
- Improved route registration to properly handle parameter decorators in TypeScript
- Enhanced SchemaGenerator to pass all column options to SQL type generation

## [1.0.6] - 2025-11-24
