majiayu000 You implement audit logging for all administrative actions in the QA Team Portal.
Requirements from PROJECT_PLAN.md
- Log all create, update, delete operations
- Capture user ID, timestamp, IP, user agent
- Display audit trail in admin panel
- Export logs to CSV
- Retention policy: 1 year minimum
Implementation
1. Audit Log Model
Location: backend/app/models/audit_log.py
from sqlalchemy import Column, String, JSON, ForeignKey, Text
from sqlalchemy.dialects.postgresql import UUID
import uuid
from app.db.base_class import Base
class AuditLog(Base):
__tablename__ = "audit_logs"
id = Column(UUID(as_uuid=True), primary_key=True, default=uuid.uuid4)
user_id = Column(UUID(as_uuid=True), ForeignKey("users.id"), nullable=False)
action = Column(String(50), nullable=False) # create, update, delete, login
entity_type = Column(String(50), nullable=False) # team_member, tool, etc.
entity_id = Column(UUID(as_uuid=True), nullable=True)
old_values = Column(JSON, nullable=True) # Before update/delete
new_values = Column(JSON, nullable=True) # After create/update
ip_address = Column(String(45), nullable=True) # IPv6 support
user_agent = Column(Text, nullable=True)
created_at = Column(DateTime, default=datetime.utcnow, nullable=False)
2. Audit Service
Location: backend/app/services/audit_service.py
from fastapi import Request
from sqlalchemy.orm import Session
from app.models.audit_log import AuditLog
from app.models.user import User
class AuditService:
"""Service for logging admin activities."""
@staticmethod
async def log_action(
db: Session,
user: User,
action: str,
entity_type: str,
entity_id: str = None,
old_values: dict = None,
new_values: dict = None,
request: Request = None
):
"""
Log an audit event.
Args:
db: Database session
user: Current user
action: Action type (create, update, delete, login)
entity_type: Type of entity (team_member, tool, etc.)
entity_id: ID of entity
old_values: Values before change
new_values: Values after change
request: FastAPI request object
"""
ip_address = None
user_agent = None
if request:
# Get real IP (behind proxy)
ip_address = request.headers.get(
"X-Forwarded-For",
request.client.host
).split(',')[0].strip()
user_agent = request.headers.get("User-Agent")
audit_log = AuditLog(
user_id=user.id,
action=action,
entity_type=entity_type,
entity_id=entity_id,
old_values=old_values,
new_values=new_values,
ip_address=ip_address,
user_agent=user_agent
)
db.add(audit_log)
db.commit()
return audit_log
3. Audit Middleware
Location: backend/app/middleware/audit_middleware.py
from starlette.middleware.base import BaseHTTPMiddleware
from fastapi import Request
from app.services.audit_service import AuditService
class AuditMiddleware(BaseHTTPMiddleware):
"""Middleware to automatically log admin actions."""
async def dispatch(self, request: Request, call_next):
response = await call_next(request)
# Only log successful admin operations
if (
response.status_code < 400 and
request.url.path.startswith("/api/v1/admin/") and
request.method in ["POST", "PUT", "PATCH", "DELETE"]
):
# Audit logging handled in endpoints
# This middleware can be used for additional logging
pass
return response
4. Usage in Endpoints
Location: backend/app/api/v1/endpoints/team_members.py
from app.services.audit_service import AuditService
@router.post("/admin/team-members")
async def create_team_member(
data: TeamMemberCreate,
request: Request,
db: Session = Depends(get_db),
current_user: User = Depends(get_current_lead_or_admin)
):
"""Create team member with audit logging."""
# Create team member
team_member = await crud.team_member.create(db, obj_in=data)
# Log action
await AuditService.log_action(
db=db,
user=current_user,
action="create",
entity_type="team_member",
entity_id=str(team_member.id),
new_values=data.dict(),
request=request
)
return team_member
@router.put("/admin/team-members/{id}")
async def update_team_member(
id: UUID,
data: TeamMemberUpdate,
request: Request,
db: Session = Depends(get_db),
current_user: User = Depends(get_current_lead_or_admin)
):
"""Update team member with audit logging."""
# Get old values
old_member = await crud.team_member.get(db, id=id)
old_values = TeamMemberResponse.from_orm(old_member).dict()
# Update team member
updated_member = await crud.team_member.update(
db,
db_obj=old_member,
obj_in=data
)
# Log action
await AuditService.log_action(
db=db,
user=current_user,
action="update",
entity_type="team_member",
entity_id=str(id),
old_values=old_values,
new_values=data.dict(exclude_unset=True),
request=request
)
return updated_member
@router.delete("/admin/team-members/{id}")
async def delete_team_member(
id: UUID,
request: Request,
db: Session = Depends(get_db),
current_user: User = Depends(get_current_admin)
):
"""Delete team member with audit logging."""
# Get old values before deletion
team_member = await crud.team_member.get(db, id=id)
old_values = TeamMemberResponse.from_orm(team_member).dict()
# Delete
await crud.team_member.remove(db, id=id)
# Log action
await AuditService.log_action(
db=db,
user=current_user,
action="delete",
entity_type="team_member",
entity_id=str(id),
old_values=old_values,
request=request
)
return {"message": "Deleted successfully"}
5. Audit Log API
Location: backend/app/api/v1/endpoints/audit_logs.py
@router.get("/admin/audit-logs")
async def get_audit_logs(
skip: int = 0,
limit: int = 100,
action: str = None,
entity_type: str = None,
user_id: UUID = None,
start_date: datetime = None,
end_date: datetime = None,
db: Session = Depends(get_db),
current_user: User = Depends(get_current_lead_or_admin)
):
"""Get audit logs with filters."""
query = db.query(AuditLog)
if action:
query = query.filter(AuditLog.action == action)
if entity_type:
query = query.filter(AuditLog.entity_type == entity_type)
if user_id:
query = query.filter(AuditLog.user_id == user_id)
if start_date:
query = query.filter(AuditLog.created_at >= start_date)
if end_date:
query = query.filter(AuditLog.created_at <= end_date)
logs = query.order_by(AuditLog.created_at.desc()).offset(skip).limit(limit).all()
return logs
@router.get("/admin/audit-logs/export")
async def export_audit_logs_csv(
db: Session = Depends(get_db),
current_user: User = Depends(get_current_admin)
):
"""Export audit logs to CSV."""
import csv
from io import StringIO
logs = db.query(AuditLog).order_by(AuditLog.created_at.desc()).all()
output = StringIO()
writer = csv.writer(output)
# Header
writer.writerow([
'Timestamp', 'User', 'Action', 'Entity Type',
'Entity ID', 'IP Address', 'User Agent'

export const AuditLogs = () => {
const [logs, setLogs] = useState([])
const [filters, setFilters] = useState({

Cleanup Policy

def cleanup_old_logs(days: int = 365):
"""Delete audit logs older than specified days."""
db = SessionLocal()
cutoff_date = datetime.utcnow() - timedelta(days=days)
deleted = db.query(AuditLog).filter(
AuditLog.created_at < cutoff_date
).delete()
db.commit()
print(f"Deleted {deleted} old audit logs")
if __name__ == "__main__":
