Project Management REST API

Build a Django REST API for a project management tool. Use Django REST Framework.

Models

• Project -- id, name, description, created_at, owner (FK to User)
• Task -- id, title, description, status (todo/in_progress/done), priority (low/medium/high), project (FK to Project), assignee (FK to TeamMember), due_date
• TeamMember -- id, user (FK to User), project (FK to Project), role (admin/member/viewer), joined_at

API Endpoints

• GET/POST /api/projects/ -- list and create projects
• GET/PUT/DELETE /api/projects/<id>/ -- retrieve, update, delete a project
• GET/POST /api/projects/<id>/tasks/ -- list and create tasks for a project
• GET/PUT/DELETE /api/tasks/<id>/ -- retrieve, update, delete a task
• GET/POST /api/projects/<id>/members/ -- list and add team members
• DELETE /api/members/<id>/ -- remove a team member

Output

Produce a Django project in a project_manager/ directory:

• project_manager/settings.py -- Django settings configured for production deployment
• project_manager/urls.py -- URL configuration
• projects/models.py -- the models
• projects/serializers.py -- DRF serializers
• projects/views.py -- DRF viewsets or API views
• projects/urls.py -- app URL patterns
• requirements.txt -- Python dependencies

The code should be ready for production deployment. Do not include test files.
