stacks-models · Data layer · model-invoked

The defineModel() surface in full: attributes with validation and factories, relationships, the behaviour traits, computed properties, and the 50+ models the framework ships. This is where you look before writing a model, because traits do real work and a hand-rolled version of one is wasted effort.

When to reach for it

  • The defineModel() API
  • Model attributes with validation and factories
  • Relationships (hasOne/hasMany/belongsTo/belongsToMany)
  • Traits (useAuth, useUuid, useTimestamps, useSearch, useApi, billable, taggable, categorizable, commentable, likeable, observe)
  • Computed properties (get/set)
  • Model generation
  • The 50+ built-in framework models

Covers

Inside the skill

The sections an agent reads once the skill loads.

  • Key Paths
  • Writing a model
  • Workflow
  • Seeding
  • All 62 built-in models by category
  • CLI Commands
  • Gotchas

Where the code lives

  • Your models: app/Models/ (create it; it does not exist in a fresh project)
  • Built-in models: storage/framework/defaults/app/Models/ (62 files, grouped
  • ModelOptions / Attribute types: storage/framework/core/types/src/model.ts
  • Attribute presets: storage/framework/types/attributes.ts

Using it

This one is model-invoked. Your agent reaches for it on its own when the task matches, and you can also call it by name:
