# Stacks Models ## Key Paths - 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 into `commerce/`, `Content/`, `realtime/` and a flat top level) - `ModelOptions` / `Attribute` types: `storage/framework/core/types/src/model.ts` - Attribute presets: `storage/framework/types/attributes.ts` To customize a built-in model, create the same filename under `app/Models/` - `app/Models/User.ts` wins over the default. `buddy publish:model User` copies the default across as a starting point. ## Writing a model Everything - schema, validation, factory, relationships, behavior - is declared in one `defineModel()` call. Migrations are derived from this; you do not write the SQL. ```ts // app/Models/Product.ts import { defineModel } from '@stacksjs/orm' import { schema } from '@stacksjs/validation' export default defineModel({ name: 'Product', // defaults to the file name table: 'products', // defaults to lowercase plural of `name` primaryKey: 'id', // default autoIncrement: true, // default traits: { useUuid: true, useTimestamps: true, useApi: { uri: 'products', routes: ['index', 'store', 'show', 'update', 'destroy'] }, useSearch: { searchable: ['name'], filterable: ['status'] }, observe: true, }, belongsTo: ['Category'], hasMany: ['Review'], attributes: { name: { required: true, fillable: true, order: 1, validation: { rule: schema.string().min(3).max(100), message: { max: 'Name must have a maximum of 100 characters' }, }, factory: faker => faker.commerce.productName(), }, status: { required: true, fillable: true, default: 'draft', validation: { rule: schema.enum(['draft', 'published', 'archived']) }, factory: faker => faker.helpers.arrayElement(['draft', 'published', 'archived']), }, }, } as const) ``` `as const` is what the built-in models use - it narrows literal types so the generated model types stay precise. ### Attribute fields `validation.rule` is the only required key on an attribute. | Field | Effect | |---|---| | `required` | Value required; emits a `NOT NULL` column | | `nullable` | Explicit nullability override | | `default` | Column default (`string \| number \| boolean \| Date`) | | `unique` | Unique constraint | | `type` | Force the column type instead of inferring from the rule | | `order` | Column order in the table and in dashboard forms | | `fillable` | Allow mass assignment | | `guarded` | Block mass assignment | | `hidden` | Exclude from JSON serialization (passwords, tokens) | | `foreignKey` | Disable, infer, or configure the FK constraint | | `factory` | `(faker) => value`, used by seeders and tests | | `validation` | `{ rule, message? }` - `rule` from `schema`, `message` keyed by rule name | ### Traits | Trait | What it adds | |---|---| | `useUuid` | UUID column alongside the primary key | | `useTimestamps` (alias `timestampable`) | `created_at` / `updated_at`. On by default | | `useSoftDeletes` (alias `softDeletable`) | `deleted_at` plus soft-delete query scopes | | `useAuth` (alias `authenticatable`) | Auth columns; `{ usePasskey: true }` adds passkeys | | `useApi` | Generates REST actions and routes: `{ uri, routes }` | | `useSearch` (alias `searchable`) | Search-engine indexing: `{ displayable, searchable, sortable, filterable }` | | `useSocials` | OAuth identities, e.g. `['github']` | | `useActivityLog` | Writes an `Activity` row per change | | `observe` | Emits `{model}:created` / `:updated` / `:deleted` events | | `billable` | Stripe methods (`checkout()`, `activeSubscription()`, ...) | | `taggable` / `categorizable` / `commentable` / `likeable` | Pivot tables and their relation methods | Also at the top level: `indexes: [{ name, columns, unique?, where? }]` for composite and partial-unique indexes, and `dashboard: { highlight: true }` to feature the model in the admin UI. ### Relationships `hasOne`, `hasMany`, `belongsTo`, `belongsToMany`, `hasOneThrough`, `hasManyThrough`, `morphOne`, `morphMany`, `morphTo`, `morphToMany`, `morphedByMany`. Each takes an array of model names, or an object form when you need to name the foreign key. ### Computed properties and scopes ```ts get: { fullName: (model) => `${model.firstName} ${model.lastName}`, }, set: { password: (value) => makeHash(value), }, scopes: { published: (query) => query.where('status', 'published'), }, ``` ## Workflow ```sh buddy make:model Product # scaffold app/Models/Product.ts buddy generate:migrations # diff models against the schema, emit SQL # review the generated file in database/migrations/ buddy migrate # apply it buddy migrate:fresh --seed # dev only: drop, re-migrate, seed ``` Models resolve at runtime through `createModel()` from `bun-query-builder` - there is no build step between editing a model and querying it. Only migrations need generating. ## Seeding Seed data is declared on the model, through the `useSeeder` trait plus the per-attribute `factory` functions: ```ts traits: { useSeeder: { count: 20, // Optional: pin specific rows over the generated ones. Keys use the // model's camelCase attribute names. fixtures: [ { name: 'Flagship Widget', status: 'published' }, ], }, }, ``` `buddy seed` walks every model carrying the trait and fills its table from the attribute factories. Nothing else is needed - no seeder files, no registration. ```bash buddy seed # every model with a useSeeder trait buddy seed --fresh # truncate each table first buddy seed --only Product,Review # just these models buddy seed --except User # everything but these buddy seed --include-defaults # framework built-ins too ``` A model with no `useSeeder` trait is never seeded. Auth and OAuth models are skipped on a non-fresh database so re-seeding cannot invalidate live sessions - pass `--allow-protected` to override. ## All 62 built-in models by category ### Users & Auth -

`buddy generate:migrations` — diff models against the schema and emit SQL - `buddy migrate` / `buddy migrate:fresh --seed` — apply migrations - `buddy make:migration [name]` — hand-write a migration instead - `buddy make:factory [name]` — standalone factory - `buddy seed` — seed every model carrying a `useSeeder` trait ## Gotchas - **No code generation step for models.** `defineModel()` calls `createModel()` from bun-query-builder at runtime, so a model is queryable the moment you save it. Only migrations are generated. - **Migrations come from models.** Change the model, run `buddy generate:migrations`, review the SQL, then `buddy migrate`. Editing a generated migration by hand will be overwritten by the next diff. - **`commentable`, not `commentables`.** `define-model` only checks the singular key. The plural spelling used to type check while leaving the trait inert. - **Seeding is model-declared.** `useSeeder` sets the count and fixtures; the per-attribute `factory` functions produce the values. There are no seeder files to write or register. - **`hidden` is serialization, `guarded` is mass assignment.** They are different protections; a password wants both `hidden` and no `fillable`. - **`validation.rule` is mandatory** on every attribute - it drives both request validation and the inferred column type. - Dashboard-highlighted models (`dashboard: { highlight: true }`) appear prominently in the admin UI.
