Ash Framework Guidelines

Ash is a declarative framework for modeling domains with resources. Read documentation before using features.

Code Interfaces

Define code interfaces on domains - avoid direct Ash.get!/2 calls in LiveViews/Controllers:

# In domain
resource Post do
  define :get_post, action: :read, get_by: [:id]
  define :list_posts, action: :read
  define :create_post, action: :create, args: [:title]
end

# Usage - prefer query option over manual Ash.Query building
posts = MyApp.Blog.list_posts!(
  query: [filter: [status: :published], sort: [published_at: :desc], limit: 10],
