# T7-1: Database Seeding & Migration Management

## Priority
Low

## Status
Completed

## Created
2025-10-16

## Description
Implement database seeding functionality with special test API keys for development and testing environments. Create seed scripts to populate the database with test data including workspaces, projects, tasks, and a dedicated test agent key. Perform and verify database migrations in both local development and production environments.

## Objectives
- Create database seed scripts for development and testing
- Generate and store a special test agent API key in the database
- Add test data (workspaces, projects, tasks, users) for local development
- Document the test API key in .env and README for developers
- Verify migrations work correctly in local environment
- Safely execute migrations in production environment
- Test all CLI and API functionality with the seeded test API key

## Acceptance Criteria
- [ ] Seed script created in `scripts/seed_database.py` or similar
- [ ] Test agent API key generated and stored in database
- [ ] Test API key added to `.env` file for local development
- [ ] Seed data includes at least:
  - [ ] 1 test workspace (e.g., "DEV")
  - [ ] 2-3 projects within the workspace
  - [ ] 5-10 sample tasks with various statuses
  - [ ] 1 test user account
  - [ ] 1 agent API key with full permissions
- [ ] Documentation added to README/docs for using test API key
- [ ] `make seed` or similar command added to Makefile
- [ ] Migrations executed successfully in local environment
- [ ] Migrations executed successfully in production environment (if applicable)
- [ ] CLI tested with seeded API key (`anyt auth login --agent-key`)
- [ ] All API endpoints tested with seeded data
- [ ] Seed script is idempotent (can be run multiple times safely)
- [ ] Seed data reset functionality (`make seed-reset`)

## Dependencies
- T1-1: Database Schema Design & Implementation (completed)
- T1-3: Authentication & Authorization Enhancement (completed)
- T2-9: Complete Repository Migration (completed)
- T3-1: CLI Foundation & Setup (completed - for testing)

## Estimated Effort
4-6 hours

### Seed Script Structure
```python
# scripts/seed_database.py
import asyncio
from backend.lib.database import get_db
from backend.lib.agent_keys import generate_agent_key, hash_agent_key
from backend.db_schema.models import (
    DBWorkspace, DBProject, DBTask, DBAgentKey
)

async def seed_database():
    """Seed database with test data."""
    async with get_db() as db:

            name="Development Workspace",
            description="Test workspace for local development"
        )

            name="CLI Development",
            description="Command-line interface for AnyTask",

                status="done",
                priority=2
            ),
            DBTask(

        print(f"\n{'='*60}\n")

if __name__ == "__main__":
    asyncio.run(seed_database())
```

### .env Configuration
Add to `.env` file:
```bash
# Test Agent Key (for local development)
TEST_AGENT_KEY=anyt_agent_<generated_key>
```

### Makefile Commands
```makefile
.PHONY: seed seed-reset

seed:
	@echo "Seeding database with test data..."
	uv run python scripts/seed_database.py

seed-reset:
	@echo "Resetting database and reseeding..."
	make db-downgrade BASE=base
	make db-migrate
	make seed
```

### Migration Verification

**Local Migration:**
```bash
# Check current migration status
make db-current

# Run migrations
make db-migrate

# Verify migrations
make db-history
```

**Production Migration:**
```bash
# IMPORTANT: Backup database first!
# Then run with production environment
export DATABASE_URL=<prod_database_url>
make db-migrate-prod

# Verify
make db-current
```

### Testing with Seeded Data

**CLI Testing:**
```bash
# Login with test agent key
anyt auth login --agent-key
# Paste: anyt_agent_<generated_key>

# Verify authentication
anyt auth whoami

# List workspaces
anyt workspace list

# Initialize workspace
anyt workspace init
# Select: DEV workspace
```

**API Testing:**
```bash
# Test with curl
export TEST_KEY="anyt_agent_<generated_key>"

# List workspaces
curl -H "X-API-Key: $TEST_KEY" http://localhost:8000/v1/workspaces

# List tasks
curl -H "X-API-Key: $TEST_KEY" http://localhost:8000/v1/workspaces/1/tasks
```

### Safety Considerations

1. **Idempotency**: Check if data exists before inserting
2. **Development Only**: Add environment check (only seed if ENVIRONMENT=development)
3. **Key Storage**: Store key hash, not plaintext
4. **Production Safety**: Prevent accidental seeding in production
5. **Backup**: Always backup production database before migrations

## Implementation Steps

1. **Create seed script**:
   - Generate test agent key
   - Create test workspace ("DEV")
   - Create sample projects
   - Create sample tasks
   - Output key to console

2. **Update .env**:
   - Add TEST_AGENT_KEY variable
   - Document in .env.example

3. **Add Makefile targets**:
   - `make seed` - Run seed script
   - `make seed-reset` - Reset and reseed

4. **Document in README**:
   - How to seed local database
   - How to use test API key
   - Testing procedures

5. **Verify migrations**:
   - Check migration status locally
   - Run migrations locally
   - Document production migration process

6. **Test functionality**:
   - CLI login with test key
   - CLI workspace commands
   - API endpoints with test key

7. **Production migration** (if applicable):
   - Backup database
   - Run migrations
   - Verify schema
   - Rollback plan ready

## Out of Scope
- User authentication seeding (focus on agent key)
- Large-scale performance testing data
- Production data seeding (production migrations only)
