SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps Rails teams implement robust multi-tenancy so tenant data stays isolated and authorization remains predictable across requests, models, and migrations.

Core Features & Use Cases

  • URL-based tenant routing that scopes every request by an account identifier in the path (with explicit scoping, not hidden defaults).
  • Per-request tenant context using Current attributes (user, account, membership) to enforce membership checks and permissions consistently.
  • Data isolation & migration strategies that prevent cross-account access and provide safe, incremental ways to add account scoping to existing tables, including UUID-based primary keys to reduce enumeration risk.
  • Rails-specific implementation guidance for models, controllers, routes, membership management, indexing, and test coverage for isolation.

Quick Start

Ask your AI assistant to outline a Rails 8 multi-tenant design using URL-based routing with Current.account scoping, UUID primary keys, indexed tenant columns, and a safe migration plan to backfill account_id from parent records.

FAQPage Schema
How do I implement secure multi-tenancy in Rails using URL-based routing?▼

Secure multi-tenancy in Rails uses URL-based account scoping by deriving Current.account from URL params, enforcing explicit membership checks, and scoping queries to prevent cross-tenant data exposure.

What's the best way to add account_id to existing Rails tables without downtime?▼

To add account_id safely, use incremental migration backfills by adding nullable account_id columns with database indexes, then progressively populate values from parent records to maintain data isolation.

How does Current attributes work for Rails tenant request context?▼

Current attributes store per-request tenant context like Current.account and Current.user, ensuring membership authorization and consistent tenant scoping across models and controllers during each request.

Why use UUID primary keys for multi-tenant data isolation?▼

UUID primary keys reduce enumeration risk in multi-tenant applications by making tenant record IDs unpredictable, which strengthens data isolation and prevents cross-account access via URL guessing.

Do I need to scope validations for multi-tenant Rails models?▼

Yes, multi-tenant Rails models require consistent scoping in queries and validations to guarantee tenant-safe operations, ensuring uniqueness checks and data access remain within the current account boundary.

How to prevent cross-tenant data access in Rails controllers?▼

Prevent cross-tenant data access by using guarded Rails controllers that enforce explicit Current.account scoping on all queries, combined with membership-based authorization checks for every request.
