Date: 2025-12-26 Issue: Issue #3 - User model enhancement with profile and API key management Status: COMPLETE

Changes Summary

Code Files Updated

  1. spektiv/api/models/user.py

    • Added tax_jurisdiction field (String(10), default="AU")
    • Added timezone field (String(50), default="Australia/Sydney")
    • Added api_key_hash field (String(255), nullable, unique, indexed)
    • Added is_verified field (Boolean, default=False)
    • Complete docstring with all attributes documented
  2. spektiv/api/services/api_key_service.py (NEW)

    • generate_api_key() - Generates secure API keys with 'ta_' prefix (256-bit entropy)
    • hash_api_key() - Hashes API keys using bcrypt via pwdlib
    • verify_api_key() - Constant-time verification to prevent timing attacks
    • Comprehensive docstrings with security notes and examples
  3. spektiv/api/services/validators.py (NEW)

    • validate_timezone() - Validates against IANA timezone database
    • validate_tax_jurisdiction() - Validates jurisdiction codes (50+ countries/states)
    • get_available_timezones() - Returns set of valid timezones
    • get_available_tax_jurisdictions() - Returns set of valid jurisdictions
    • Comprehensive docstrings with valid/invalid examples
  4. migrations/versions/002_add_user_profile_fields.py

    • Migration to add new user profile fields to database
    • Proper defaults for existing users
    • Rollback support with downgrade() function
    • Complete docstrings

Documentation Updated

CHANGELOG.md

Status: UPDATED

  • Added Issue #3 entry under "### Added" section with 15 sub-items
  • Entry placed immediately after Issue #48 (FastAPI backend) since it extends the User model
  • Includes file references with line numbers for precise navigation
  • Documents all security features (bcrypt hashing, constant-time verification)
  • Lists supported jurisdictions (50+) and timezone database usage

Lines Added: 17 new lines Entry Location: Lines 39-54 in CHANGELOG.md

Documentation Quality Checklist

Docstring Completeness

  • User model class has complete docstring with all attributes
  • api_key_service.py has docstrings for all 3 functions
  • All functions include Parameters, Returns, and Examples sections
  • Security considerations documented in relevant functions
  • validators.py has comprehensive examples (valid and invalid cases)

Code Organization

  • All files follow Python docstring conventions (PEP 257)
  • Module-level docstrings explain purpose and usage
  • Security concerns highlighted in docstrings
  • Type hints present on all function signatures

Referenced Files (All Verified)

  • spektiv/api/models/user.py - User model with enhanced fields
  • spektiv/api/services/api_key_service.py - API key management
  • spektiv/api/services/validators.py - Field validators
  • migrations/versions/002_add_user_profile_fields.py - Database schema

Cross-Reference Validation

  • All file paths in CHANGELOG are accurate
  • Line numbers point to correct code sections
  • No broken links or references
  • Models are properly exported in models/init.py

Features Documented

User Profile Enhancement

  1. Tax Jurisdiction Field

    • Supports country-level codes (ISO 3166-1: US, AU, GB, etc.)
    • Supports state/province codes (US-CA, AU-NSW, CA-ON, etc.)
    • Default: "AU" (Australia)
    • Validated by validate_tax_jurisdiction()
  2. Timezone Field

    • IANA timezone identifiers (America/New_York, UTC, Asia/Tokyo)
    • Default: "Australia/Sydney"
    • Validated by validate_timezone()
    • Case-sensitive, must match IANA database exactly
  3. API Key Management

    • api_key_hash field for secure programmatic access
    • Generation: generate_api_key() returns plaintext with 'ta_' prefix
    • Storage: hash_api_key() hashes before database storage
    • Verification: verify_api_key() uses constant-time comparison
    • Format: ta_<base64url(32 bytes)> ≈ ta_<40+ characters>
  4. Email Verification

    • is_verified boolean field tracks verification status
    • Default: False (unverified)
    • Can be updated after email confirmation

Security Features Documented

  • Bcrypt hashing via pwdlib.PasswordHash for API keys
  • 256-bit entropy (32 bytes) for API key generation
  • Constant-time comparison to prevent timing attacks
  • Unique constraint on api_key_hash for database integrity
  • Indexed api_key_hash for fast lookups
  • Server-side defaults for backwards compatibility

Database Migration

  • Version: 002
  • Revises: 001
  • Tables Modified: users
  • Columns Added: 4 (tax_jurisdiction, timezone, api_key_hash, is_verified)
  • Constraints: 1 unique constraint on api_key_hash, 1 index
  • Rollback: Fully supported with downgrade()

Additional Notes

  • No new API documentation files created (builds on existing FastAPI structure)
  • Schemas may be extended in separate issue if needed for CRUD endpoints
  • Validators can be used in Pydantic models for request/response validation
  • All new services are properly typed with type hints
  • Comprehensive examples provided in docstrings for developer reference
