Custom Task Status Manager Implementation

Overview

Implementation of the CustomTaskStatusManager component for displaying and managing custom task statuses in the project settings.

Component: frontend/src/components/settings/CustomTaskStatusManager.vue

Task: Task 11 from .kiro/specs/vfx-project-management/custom-task-status-tasks.md

Requirements: 1.1, 8.1, 8.2, 8.3

Features Implemented

1. Status List Display ✅

The component displays two sections:

System Statuses Section

• Shows all built-in system statuses (not_started, in_progress, submitted, approved, retake)
• Each status displays:
  • Color indicator (colored circle)
  • Status name (formatted with spaces instead of underscores)
  • "System" badge
  • Task count
• System statuses have a light gray background to distinguish them from custom statuses
• System statuses cannot be edited or deleted

Custom Statuses Section

• Shows all custom statuses defined for the project
• Each status displays:
  • Color indicator (colored circle)
  • Status name
  • "Default" badge with star icon (if it's the default status)
  • "Custom" badge (if not default)
  • Task count
  • Edit button (pencil icon)
  • Delete button (trash icon)
• Custom status rows have hover effects
• Empty state message when no custom statuses exist

2. Visual Indicators ✅

• Color Indicators: Each status shows a colored circle using the status's configured color
• Default Status Badge: Default status displays a "Default" badge with a star icon
• System Badge: System statuses display a "System" badge
• Custom Badge: Non-default custom statuses display a "Custom" badge
• Icons:
  • Shield icon for System Statuses section
  • Palette icon for Custom Statuses section
  • Plus icon for Add Status button
  • Pencil icon for Edit button
  • Trash icon for Delete button
  • Star icon for Default badge

3. Task Count Display ✅

• Each status (system and custom) displays the number of tasks using that status
• Format: "X task" or "X tasks" (proper pluralization)
• Currently shows "0 tasks" as placeholder (actual counts require backend enhancement)
• Task counts are displayed on the right side of each status row

Note: The backend API currently doesn't return task counts. This will need to be implemented in a future enhancement. The component is ready to display counts when the API is updated.

4. Add Status Button ✅

• "Add Status" button is prominently displayed in the Custom Statuses section header
• Button includes a Plus icon
• Clicking the button currently shows a "Coming Soon" toast (dialog implementation is Task 12)

5. Loading and Error States ✅

Loading State

• Displays a centered spinner while fetching status data
• Shows during initial component mount and when reloading data

Error State

• Displays error message in a red-bordered box
• Shows "Try Again" button to retry loading
• Error message comes from API response or generic fallback

Success State

• Displays the full status list with system and custom statuses
• Smooth transition from loading to content display

Component Structure

Props

interface Props {
  projectId: number  // Required: The project ID to load statuses for
}

Emits

{
  updated: []  // Emitted when statuses are updated (for parent to refresh)
}

State Management

• isLoading: Boolean for loading state
• loadError: String for error messages
• allStatuses: AllTaskStatusesResponse from API
• taskCounts: Record<string, number> for task counts per status

Computed Properties

• systemStatuses: Array of system statuses from API response
• customStatuses: Array of custom statuses from API response
• defaultStatusId: ID of the default status

API Integration

Endpoint Used

GET /projects/{project_id}/task-statuses

Response Structure

interface AllTaskStatusesResponse {
  statuses: CustomTaskStatus[]           // Custom statuses
  system_statuses: SystemTaskStatus[]    // System statuses
  default_status_id: string              // ID of default status
}

interface CustomTaskStatus {
  id: string
  name: string
  color: string
  order: number
  is_default: boolean
}

interface SystemTaskStatus {
  id: string
  name: string
  color: string
  is_system: boolean
}

Integration

Project Settings View

The component is integrated into ProjectSettingsView.vue in the Tasks tab:

<TabsContent value="tasks" class="mt-6">
  <div class="space-y-6">
    <!-- Custom Task Status Manager -->
    <div class="bg-card rounded-lg border p-6">
      <CustomTaskStatusManager
        :project-id="projectId"
        @updated="handleTaskStatusesUpdated"
      />
    </div>
    
    <Separator />
    
    <!-- Other task-related components... -->
  </div>
</TabsContent>

Styling

• Uses shadcn-vue components for consistent styling
• Follows the same design patterns as CustomTaskTypeManager
• Responsive layout with proper spacing
• Hover effects on interactive elements
• Color indicators use inline styles for dynamic colors
• Proper use of muted colors for secondary text

Future Enhancements

Task 12: Add/Edit Status Dialog

• Implement dialog for creating new statuses
• Implement dialog for editing existing statuses
• Add color picker component
• Add name validation

Task 13: Delete Status Confirmation

• Implement delete confirmation dialog
• Show task count in confirmation
• Add reassignment option if status is in use

Task 14: Drag-and-Drop Reordering

• Add drag-and-drop functionality for reordering statuses
• Update order via API
• Persist order changes

Task 15: Default Status Management

• Add "Set as Default" functionality
• Update default status via API
• Ensure only one default at a time

Backend Enhancement: Task Counts

The backend API needs to be enhanced to return task counts:

# Suggested endpoint enhancement
@router.get("/{project_id}/task-statuses")
async def get_all_task_statuses(...):
    # ... existing code ...
    
    # Add task count query
    task_counts = {}
    for status in all_statuses:
        count = db.query(Task).filter(
            Task.project_id == project_id,
            Task.status == status.id
        ).count()
        task_counts[status.id] = count
    
    return {
        "statuses": custom_statuses,
        "system_statuses": system_statuses,
        "default_status_id": default_status_id,
        "task_counts": task_counts  # NEW
    }
