# Task 20: Shot Table View with Task Status Display - Implementation Summary

## Overview
Successfully implemented a comprehensive shot table view with task status display, filtering, sorting, and column visibility controls. This feature mirrors the asset table functionality and provides coordinators with a powerful tool to track shot production progress.

## Completed Sub-tasks

### 20.1 Enhanced Backend Shot List Endpoint with Task Status ✅

**Backend Changes:**

1. **Updated Shot Schema** (`backend/schemas/shot.py`):
   - Added `TaskStatusInfo` class for detailed task information
   - Extended `ShotListResponse` with:
     - `task_status`: Dictionary mapping task types to their status
     - `task_details`: List of detailed task information including task_id and assigned_user_id

2. **Enhanced Shots Router** (`backend/routers/shots.py`):
   - Added query parameters to `list_shots` endpoint:
     - `task_status_filter`: Filter shots by specific task type and status (format: "task_type:status")
     - `sort_by`: Sort by any field including task status columns
     - `sort_direction`: Sort direction (asc/desc)
   - Implemented task status aggregation:
     - Queries all tasks for each shot
     - Builds task_status dictionary with all task types (standard + custom)
     - Initializes missing task types as NOT_STARTED
     - Populates task_details with complete task information
   - Added task status filtering logic
   - Implemented task status sorting with proper status order

3. **Testing**:
   - Created `backend/test_shot_task_status.py` to verify endpoint functionality
   - Tested task status retrieval, filtering, and sorting
   - Confirmed custom task types are included in response

### 20.2 Created Shot Table View Component ✅

**Frontend Changes:**

     - Shot Name (with camera icon)
     - Episode (with badge)
     - Frame Range (with frame count)
     - Status (with color-coded badge)
     - Task Status columns (dynamic based on project task types)
     - Description
     - Actions dropdown menu
   - Features:
     - Row click handling for selection (single, multi-select with Ctrl, range select with Shift)
     - Sortable columns with visual indicators
     - Task status badges with consistent 140px width
     - Responsive design with horizontal scroll for many columns
     - Hover states and selected row highlighting

   - Extended `Shot` interface with task_status and task_details
   - Added `TaskStatus` enum
   - Created `ShotListOptions` interface for query parameters
   - Updated `getShots` method to support filtering and sorting options

### 20.3 Implemented Column Visibility Control for Shots ✅

**Frontend Changes:**

1. **New Component** (`frontend/src/components/shot/ShotColumnVisibilityControl.vue`):
   - Dropdown menu with checkboxes for each column
   - Separate sections for:
     - Basic columns (Shot Name, Episode, Frame Range, Status, Description)
     - Task status columns (dynamically generated from project task types)
   - Quick actions:
     - "Show All" - Makes all columns visible
     - "Hide All" - Hides all columns except Shot Name (required)
   - Session storage persistence for user preferences
   - Dynamic task type support (works with custom task types)

### 20.4 Added Task Status Filtering and Sorting ✅

**Frontend Changes:**

1. **New Component** (`frontend/src/components/shot/ShotTaskStatusFilter.vue`):
   - Dropdown filter with task type and status combinations
   - Dynamically generates filter options based on project task types
   - Status options: Not Started, In Progress, Submitted, Approved, Retake
   - Visual task status badges in dropdown
   - Clear filter button when filter is active
   - Emits filter changes to parent component

2. **Sorting Implementation**:
   - Column headers are clickable to toggle sort
   - Sort indicators show current sort field and direction
   - Supports sorting by:
     - Basic fields (name, status, frame_start, frame_end, etc.)
     - Task status columns (with proper status order)
   - Backend handles sorting for optimal performance

### 20.5 Integrated Shot Table with Project Shots View ✅

**Frontend Changes:**

1. **Updated ShotBrowser** (`frontend/src/components/shot/ShotBrowser.vue`):
   - Added table view mode toggle (Grid | List | Table)
   - Integrated ShotsTableView component
   - Added ShotTaskStatusFilter for table view
   - Added ShotColumnVisibilityControl for table view
   - Implemented episode loading for episode name display
   - Implemented task type loading (standard + custom)
   - Added state management for:
     - Column visibility with session storage
     - Task status filtering
     - Sort field and direction
   - Added handlers for:
     - Task status filter changes
     - Sort changes
   - Watchers for:
     - Project changes to reload episodes and task types
     - Column visibility changes to persist preferences
   - Default view mode set to 'table' for immediate access

2. **Integration Features**:
   - Seamless switching between grid, list, and table views

## Technical Implementation Details

### Backend Architecture
- **Query Optimization**: Single query per shot with task aggregation
- **Custom Task Type Support**: Dynamically includes custom task types in response
- **Filtering**: Server-side filtering for better performance with large datasets
- **Sorting**: Server-side sorting with proper status order handling

### Frontend Architecture
- **Component Reusability**: Created shot-specific components following asset table patterns

### Data Flow
1. User selects episode in ProjectShotsView
2. ShotBrowser loads shots with task status from backend
3. ShotBrowser loads episodes and task types for display
4. User can filter by task status (triggers backend reload)
5. User can sort by any column (triggers backend reload)
6. User can toggle column visibility (stored in session)
7. User can select shots to view details or perform actions

## Key Features

## Conclusion

Task 20 has been successfully completed with all sub-tasks implemented and tested. The shot table view provides a powerful tool for production tracking, matching the functionality of the asset table while being tailored to shot-specific needs. The implementation follows best practices for code organization, performance, and user experience.

The feature is production-ready and provides coordinators with the tools they need to efficiently track shot production progress across episodes and projects.
