What problem does it solve?

This Skill provides a comprehensive guide to creating new domain resources using the Ash Framework, ensuring proper data modeling, multi-tenancy, and integration with PostgreSQL and ElectricSQL.

Core Features & Use Cases

  • Declarative Resource Definition: Learn to define resources, attributes, relationships, and actions in a declarative Elixir syntax.
  • Multi-Tenancy Enforcement: Understand how to implement organization-scoped data isolation, a critical requirement for most applications.
  • Use Case: You need to add a new Product entity to your e-commerce backend. This Skill will guide you through defining the Product resource, its attributes (like name, price, organization_id), its relationship to Organization, and the necessary CRUD actions, ensuring it's ready for sync and secure.

Quick Start

Use the creating ash resources skill to define a new Product resource with name, price, and organization_id attributes.

FAQPage Schema
How do I define a new resource in Ash Framework with Elixir and PostgreSQL?▼

To define an Ash Framework resource, you create a module using declarative Elixir syntax to specify attributes, relationships, and actions, then configure the PostgreSQL data layer and register the resource within your domain.

How does multi-tenancy work when creating Ash resources for organization scoping?▼

Multi-tenancy in Ash resources works by enforcing organization-scoped data isolation, requiring a mandatory organization_id attribute on resources to ensure data is securely partitioned per tenant within the PostgreSQL database.

What are common pitfalls when creating Ash resources in an Elixir Phoenix application?▼

Common pitfalls when creating Ash resources include using incorrect attribute types, failing to enforce mandatory organization scoping, and missing resource registration within the domain, which prevents proper migration generation and functionality.

What is the process for generating migrations after defining an Ash resource?▼

After declaratively defining your Ash resource and registering it in the domain, you generate the corresponding PostgreSQL migration files to update the database schema, followed by running tests to verify the resource behavior.

Can I use Ash Framework version 3.0 for multi-tenant data modeling in Phoenix?▼

Yes, Ash Framework version 3.0 supports multi-tenant data modeling within a Phoenix application, providing declarative resource definitions and enforcing organization-scoped data isolation for secure PostgreSQL architectures.
