# Custom Task Status Migration - Task 1 Implementation Summary
|
|
|
|
## Overview
|
|
Successfully implemented database schema changes and migration to support custom task statuses in the VFX Project Management System.
|
|
|
|
## Changes Made
|
|
|
|
### 1. Database Schema Updates
|
|
|
|
#### Project Model (`backend/models/project.py`)
|
|
- ✅ Added `custom_task_statuses` JSON column to store project-specific custom statuses
|
|
- Column initialized with empty array `[]` for all existing projects
|
|
|
|
#### Task Model (`backend/models/task.py`)
|
|
- ✅ Changed `status` field from `Enum(TaskStatus)` to `String`
|
|
- Updated default value from `TaskStatus.NOT_STARTED` to `"not_started"`
|
|
- Maintains backward compatibility with existing system statuses
|
|
|
|
### 2. Schema Updates (`backend/schemas/task.py`)
|
|
- ✅ Updated `TaskBase.status` from `TaskStatus` enum to `str` type
|
|
- ✅ Updated `TaskUpdate.status` from `Optional[TaskStatus]` to `Optional[str]`
|
|
- ✅ Updated `TaskStatusUpdate.status` from `TaskStatus` to `str`
|
|
- Changed default value to `"not_started"` (lowercase string)
|
|
|
|
### 3. Router Updates
|
|
Updated all routers to use string values instead of TaskStatus enum:
|
|
|
|
#### Assets Router (`backend/routers/assets.py`)
|
|
- ✅ Changed task creation to use `status="not_started"`
|
|
- ✅ Updated status initialization in task status aggregation
|
|
- ✅ Updated status filtering to use string comparison
|
|
- ✅ Updated status sorting to use string-based status order
|
|
|
|
#### Reviews Router (`backend/routers/reviews.py`)
|
|
- ✅ Updated submission status checks to use `"submitted"` string
|
|
- ✅ Changed approval status update to `"approved"` string
|
|
- ✅ Changed retake status update to `"retake"` string
|
|
|
|
#### Shots Router (`backend/routers/shots.py`)
|
|
- ✅ Changed task creation to use `status="not_started"`
|
|
- ✅ Updated status initialization in task status aggregation
|
|
- ✅ Updated status filtering to use string comparison
|
|
- ✅ Updated status sorting to use string-based status order
|
|
|
|
### 4. Migration Script (`backend/migrate_custom_task_statuses.py`)
|
|
Created comprehensive migration script that:
|
|
- ✅ Adds `custom_task_statuses` column to projects table
|
|
- ✅ Initializes column with empty array `[]` for existing projects
|
|
- ✅ Converts existing uppercase enum values to lowercase strings:
|
|
- `NOT_STARTED` → `not_started`
|
|
- `IN_PROGRESS` → `in_progress`
|
|
- `SUBMITTED` → `submitted`
|
|
- `APPROVED` → `approved`
|
|
- `RETAKE` → `retake`
|
|
- ✅ Provides detailed logging of conversion process
|
|
- ✅ Includes verification steps
|
|
|
|
### 5. Test Script (`backend/test_custom_task_status_migration.py`)
|
|
Created verification test that confirms:
|
|
- ✅ `custom_task_statuses` column exists in projects table
|
|
- ✅ Task status column supports string values
|
|
- ✅ All existing task statuses are valid lowercase strings
|
|
- ✅ `custom_task_statuses` is initialized as empty array
|
|
- ✅ Displays task status distribution
|
|
|
|
## Migration Results
|
|
|
|
### Database Changes
|
|
```
|
|
Projects Table:
|
|
- Added column: custom_task_statuses (TEXT/JSON)
|
|
|
|
Tasks Table:
|
|
- Status column: VARCHAR(11) (already TEXT, no change needed)
|
|
```
|
|
|
|
### Data Conversion
|
|
Successfully converted 105 tasks:
|
|
- 91 tasks: `NOT_STARTED` → `not_started`
|
|
- 9 tasks: `IN_PROGRESS` → `in_progress`
|
|
- 4 tasks: `RETAKE` → `retake`
|
|
- 1 task: `APPROVED` → `approved`
|
|
|
|
## System Status Values
|
|
The following system statuses remain available:
|
|
- `not_started` - Task has not been started
|
|
- `in_progress` - Task is currently being worked on
|
|
- `submitted` - Task work has been submitted for review
|
|
- `approved` - Task has been approved
|
|
- `retake` - Task requires revisions
|
|
|
|
## Backward Compatibility
|
|
- ✅ All existing tasks continue to work with lowercase string statuses
|
|
- ✅ System statuses are always available across all projects
|
|
- ✅ No breaking changes to existing API endpoints
|
|
- ✅ Frontend can continue using existing status values
|
|
|
|
## Next Steps
|
|
With the database schema and migration complete, the system is ready for:
|
|
1. Backend API endpoints for custom status CRUD operations (Task 2-8)
|
|
2. Frontend components for custom status management (Task 10-21)
|
|
3. Integration with task creation and status update workflows
|
|
|
|
## Testing
|
|
All tests passed successfully:
|
|
- ✅ Backend imports without errors
|
|
- ✅ Database schema verification
|
|
- ✅ Data conversion verification
|
|
- ✅ Status value validation
|
|
|
|
## Requirements Validated
|
|
- ✅ Requirement 6.1: System statuses remain available
|
|
- ✅ Requirement 6.2: Backward compatibility maintained
|
|
- ✅ Requirement 6.3: Existing tasks continue to work
|
|
- ✅ Requirement 9.1: Database schema supports custom statuses
