Tenant membership model for team access.
|
|
|
|
This model represents TENANT-SPECIFIC roles, which are distinct from global user roles.
|
|
|
|
TENANT ROLES (stored here):
|
|
- owner: Full control of the tenant, can transfer ownership, manage all aspects
|
|
- admin: Tenant administrator, can manage team members and most operations
|
|
- member: Standard team member, regular operational access
|
|
- viewer: Read-only observer, view-only access to tenant data
|
|
|
|
ROLE MAPPING TO GLOBAL ROLES:
|
|
When users are created through tenant management (pilot phase), their tenant role
|
|
is mapped to a global user role in the Auth service:
|
|
- tenant 'admin' → global 'admin' (system-wide admin access)
|
|
- tenant 'member' → global 'manager' (management-level access)
|
|
- tenant 'viewer' → global 'user' (basic user access)
|
|
- tenant 'owner' → No automatic global role (owner is tenant-specific)
|
|
|
|
This mapping is implemented in app/api/tenant_members.py lines 68-76.
|
|
|
|
Note: user_id is a cross-service reference (no FK) to avoid circular dependencies.
|
|
User enrichment is handled at the service layer via Auth service calls.
