- Enhanced validateDeclaration() to check for column existence
- Falls back to basic validation if enhanced columns don't exist
- Updated migration script with proper column existence checks
- Uses dynamic SQL to avoid errors on existing columns
- System now works with or without the additional columns
- Graceful degradation for different database states
- Created migration to change line_label from varchar(255) to TEXT
- Added truncation logic to prevent future line_label length issues (1000 char limit)
- This fixes the issue where 11 accounts mapped to line 08 base caused display problems
- The calculation should now work correctly with any number of account mappings
- Added comprehensive field naming documentation (CA3_FIELD_NAMING.md)
- Implemented PDFTK-based PDF form filling with FDF generation
- Added PDFTK installation guide for Linux/Mac/Windows
- Enhanced PDF generation with company data integration
- Added new CA-3 lines: F1, F2 (intracom acquisitions), E1-E6, F6-F8, line 18
- Updated section structure: merged Section C into Section B as sub-section
- Added lines 19, 20 to TVA DÉDUCTIBLE sub-section
- Updated all field descriptions to match official CA-3 form
- Improved visual hierarchy with dark blue section headers
- Enhanced calculation logic for VAT deductible amounts
- Added comprehensive language translations
- Updated database schema with new fields
- Fixed font settings to use Courier New 9pt for official documents
SQL Path Fix:
- Fixed module init() to look in /custom/declarationtva/sql/ instead of /declarationtva/sql/
- Updated dolibarr_allversions.sql with MVP schema content
- Ensures tables are created with correct structure from the start
Schema Updates:
- Uses MVP schema with correct unique constraints
- Supports multiple accounts per CA-3 line from creation
- Includes all necessary tables for basic functionality
- Proper indexes and foreign key constraints
The module should now create tables properly when activated!
Database Schema Fix:
- Fixed unique constraint to allow multiple accounts per CA-3 line
- Changed from (entity, ca3_line) to (entity, ca3_line, account_code)
- Added migration script to update existing tables
- Updated table comments to reflect new CA-3 line structure
Debug Features Added:
- Database operation logging in updateAccountMapping method
- Table existence and structure checking in setup page
- Detailed error logging for SQL operations
- Form data processing visibility
The issue was likely the unique constraint preventing multiple accounts per line!
MVP Database Schema:
- Simplified database schema for MVP development
- Core tables: config, account_mappings, periods, declarations, ca3_lines
- Basic indexes for performance
- Initial configuration data

- Period management and declaration creation
- Status tracking (draft, validated, submitted)
- Basic action handling
Configuration Interface:
- setup_mvp.php: Simplified configuration page
- PCG account mapping for all CA-3 lines
- Account selection from Dolibarr chart of accounts
- VAT rate configuration
Key Features Implemented:
- Basic CA-3 form generation
- PCG account mapping (one account per line for MVP)
- Period management (quarterly)
- Declaration status tracking
- Configuration interface
- Account validation against Dolibarr
Next Steps:
- CA-3 form generation logic
- PDF export functionality
- Testing with sample data
MVP Progress: 60% complete
