* Introduce `logic_operator` field to combine filters with OR logic.
* Implement grouping for consecutive OR filters to ensure proper SQL precedence.
* Add support for custom SQL operators in filter conditions.
* Enhance `fetch_row_number` functionality to return specific record with its position.
* Update tests to cover new filter logic and grouping behavior.
Features Implemented:
1. OR Logic Filter Support (SearchOr)
- Added to resolvespec, restheadspec, and websocketspec
- Consecutive OR filters are automatically grouped with parentheses
- Prevents SQL logic errors: (A OR B OR C) AND D instead of A OR B OR C AND D
2. CustomOperators
- Allows arbitrary SQL conditions in resolvespec
- Properly integrated with filter logic
3. FetchRowNumber
- Uses SQL window functions: ROW_NUMBER() OVER (ORDER BY ...)
- Returns only the specific record (not all records)
- Available in resolvespec and restheadspec
- Perfect for "What's my rank?" queries
4. RowNumber Field Auto-Population
- Now available in all three packages: resolvespec, restheadspec, and websocketspec
- Uses simple offset-based math: offset + index + 1
- Automatically populates RowNumber int64 field if it exists on models
- Perfect for displaying paginated lists with sequential numbering
* Added DriverName method to BunAdapter, GormAdapter, and PgSQLAdapter for consistent driver name handling.
* Updated transaction adapters to include driver name.
* Enhanced mock database implementations for testing with DriverName method.
* Adjusted getTableName functions to accommodate driver-specific naming conventions.
