| 3 | +## Overview |
| 4 | +This document explains the refactoring of the `AbstractKanbanAdapter` class into trait-based components for better separation of concerns, maintainability, and testability. |
| 5 | + |
| 6 | +## Refactoring Approach |
| 7 | + |
| 8 | +The original monolithic `AbstractKanbanAdapter` class was responsible for multiple concerns: |
| 9 | +- Database queries |
| 10 | +- Card formatting |
| 11 | +- CRUD operations |
| 12 | +- Form handling |
| 13 | +- Livewire integration |
| 14 | + |
| 15 | +Following the Single Responsibility Principle, these concerns have been extracted into focused traits: |
| 16 | + |
| 17 | +### 1. QueryHandlingTrait |
| 18 | +- Handles all database query operations |
| 19 | +- Responsible for retrieving models, filtering by columns, counting items |
| 20 | +- Examples: `newQuery()`, `getItems()`, `getItemsForColumn()`, `getColumnItemsCount()` |
| 21 | + |
| 22 | +### 2. CardFormattingTrait |
| 23 | +- Responsible for transforming Eloquent models into card data structures for the UI |
| 24 | +- Methods: `formatCardForDisplay()`, `formatCardsForDisplay()` |
| 25 | + |
| 26 | +### 3. CrudOperationsTrait |
| 27 | +- Handles create, read, update, delete operations for cards |
| 28 | +- Also manages card ordering and column assignments |
| 29 | +- Methods: `createRecord()`, `updateCard()`, `deleteCard()`, `updateCardsOrderAndColumn()` |
| 30 | + |
| 31 | +### 4. FormHandlingTrait |
| 32 | +- Generates and configures forms for creating and editing cards |
| 33 | +- Methods: `getConfig()`, `getCreateForm()`, `getEditForm()` |
| 34 | + |
| 35 | +### 5. LivewireIntegrationTrait |
| 36 | +- Handles Livewire-specific serialization and deserialization |
| 37 | +- Methods: `toLivewire()`, `fromLivewire()` |
| 38 | + |
| 39 | +## Benefits of This Approach |
| 40 | + |
| 41 | +### Improved Maintainability |
| 42 | +- Each trait has a clear, focused responsibility |
| 43 | +- Changes to one aspect (e.g., card formatting) don't affect unrelated code |
| 44 | +- Easier to understand each component in isolation |
| 45 | + |
| 46 | +### Enhanced Testability |
| 47 | +- Traits can be tested independently with mock dependencies |
| 48 | +- Reduced test complexity due to smaller focused components |
| 49 | + |
| 50 | +### Better Code Organization |
| 51 | +- Clear separation between different types of operations |
| 52 | +- Easier to locate specific functionality |
| 53 | +- Reduced cognitive load when working with the codebase |
| 54 | + |
| 55 | +### Extensibility |
| 56 | +- New adapters can selectively use only the traits they need |
| 57 | +- Custom adapters can override specific traits while keeping others |
| 58 | + |
| 59 | +### Reduced Code Duplication |
| 60 | +- Common functionality is centralized in traits |
| 61 | +- Implementations can be shared across different adapter classes |
| 62 | + |
| 63 | +## Implementation Notes |
| 64 | + |
| 65 | +1. The traits are designed to work with the `$baseQuery` and `$config` properties from the main adapter class |
| 66 | +2. Type declarations and PHPDoc are preserved for better IDE support |
| 67 | +3. Each trait follows PSR-12 coding standards and maintains strict typing |
