When creating devices via API, organization_id is now properly defaulted
to the authenticated organization's ID even when an empty string is sent.
This fixes Terraform provider compatibility where organization_id may be
sent as "" instead of omitted entirely.
Before: Only checked if key was missing (Map.has_key?)
After: Also handles nil and empty string values
Created API token system for programmatic access:
- API tokens table with organization scoping
- ApiTokens context for token management
- ApiAuth plug for Bearer token authentication
- Tokens shown once on creation, then hashed for security
Implemented RESTful API v1 endpoints:
- SitesController: CRUD operations for sites
- DevicesController: CRUD operations for devices
- All operations scoped to authenticated organization
- Proper authorization checks via site ownership
Technical details:
- Tokens prefixed with "towerops_" for easy identification
- SHA-256 hashing for token storage
- Last used timestamp tracking (async update)
- Optional token expiration support
- Standard JSON error responses (40x status codes)
Routes:
- /api/v1/sites (GET, POST, PATCH, DELETE)
- /api/v1/devices (GET, POST, PATCH, DELETE)
Authentication:
- Authorization: Bearer towerops_xxxxx header required
- Returns 401 for invalid/expired tokens
- Returns 403 for unauthorized resource access
