defineModel() API (define-model.ts)

Wraps bun-query-builder's createModel() with Stacks-specific enhancements:

• Event dispatching via traits.observe (emits {model}:created, {model}:updated, {model}:deleted via @stacksjs/events)
• Trait methods (billable, taggable, categorizable, commentable, likeable, 2FA)
• Raw definition access for generators (getDefinition(), _isStacksModel)

import { defineModel } from '@stacksjs/orm'

export default defineModel({
  name: 'Product',
  table: 'products',
  primaryKey: 'id',        // default: 'id'
  autoIncrement: true,     // default: true

  traits: {
    useUuid: true,          // adds uuid column

    },
    status: {
      fillable: true,
      default: 'draft',
      validation: { rule: schema.enum(['draft', 'published', 'archived']) }
    },

} as const)

How defineModel() Works Internally

1. buildEventHooks(definition) -- if traits.observe is truthy, creates afterCreate/afterUpdate/afterDelete hooks that lazy-import @stacksjs/events and call dispatch()
2. Merges event hooks with any user-defined hooks
3. Calls createModel(defWithHooks) from bun-query-builder (provides typed query methods)
4. buildTraitMethods(definition) -- checks each trait flag and creates method objects
5. Returns Object.assign(baseModel, traitMethods, definition) + getDefinition() + _isStacksModel

Transactions (transaction.ts)

import { transaction, savepoint, transactional } from '@stacksjs/orm'

// Basic transaction -- auto-commit on success, auto-rollback on error
const result = await transaction(async (tx) => {
  await tx.insertInto('users').values({ name: 'John' }).execute()
  await tx.insertInto('profiles').values({ user_id: 1 }).execute()
  return 'success'
})

// With options
await transaction(callback, {
  retries: 3,
  isolation: 'serializable',  // 'read committed' | 'repeatable read' | 'serializable'
  readOnly: false,
  onRollback: (error) => console.error(error),
  afterRollback: () => { /* cleanup */ }
})

// Savepoints (nested transactions)
await transaction(async (tx) => {
  await tx.insertInto('users').values({ name: 'Bob' }).execute()
  await savepoint(async (sp) => {
    await sp.insertInto('logs').values({ action: 'created' }).execute()
    // If this fails, only this savepoint rolls back
  })
})

// Decorator-style -- wraps function to auto-run in transaction
const createUser = transactional(async (tx, name: string, email: string) => {
  const user = await tx.insertInto('users').values({ name }).returningAll().executeTakeFirst()
  await tx.insertInto('profiles').values({ user_id: user.id }).execute()
  return user
})
await createUser('Alice', 'alice@example.com') // auto-wrapped

Both transaction() and savepoint() delegate to db.transaction() and db.savepoint() from @stacksjs/database.

Trait Methods (traits/)

Taggable (when traits.taggable: true)

Uses taggable table with polymorphic taggable_type + taggable_id columns.

• Model._taggable.tags(id: number): Promise<any[]>
• Model._taggable.tagCount(id: number): Promise<number> -- uses count(*)
• Model._taggable.addTag(id, { name, description? }): Promise<any> -- auto-generates slug
• Model._taggable.activeTags(id): Promise<any[]> -- filters is_active = true
• Model._taggable.inactiveTags(id): Promise<any[]> -- filters is_active = false
• Model._taggable.removeTag(id, tagId): Promise<void>

Categorizable (when traits.categorizable: true)

Uses categorizable + categorizable_models pivot table.

• Model._categorizable.categories(id): Promise<any[]> -- joins through pivot
• Model._categorizable.categoryCount(id): Promise<number>
• Model._categorizable.addCategory(id, { name, description? }): Promise<any> -- creates category if not exists, then links
• Model._categorizable.activeCategories(id): Promise<any[]>
• Model._categorizable.inactiveCategories(id): Promise<any[]>
• Model._categorizable.removeCategory(id, categoryId): Promise<void> -- removes pivot link

Commentable (when traits.commentables: true)

Uses comments table with commentables_id + commentables_type columns.

• Model._commentable.comments(id): Promise<any[]>
• Model._commentable.commentCount(id): Promise<number>
• Model._commentable.addComment(id, { title, body }): Promise<any> -- status defaults to 'pending'
• Model._commentable.approvedComments(id): Promise<any[]> -- status = 'approved'
• Model._commentable.pendingComments(id): Promise<any[]> -- status = 'pending'
• Model._commentable.rejectedComments(id): Promise<any[]> -- status = 'rejected'

Likeable (when traits.likeable: true or { table?, foreignKey? })

Table defaults to {tableName}_likes, FK defaults to {singular}_id.

• Model._likeable.likes(id): Promise<any[]>
• Model._likeable.likeCount(id): Promise<number>
• Model._likeable.like(id, userId): Promise<any>
• Model._likeable.unlike(id, userId): Promise<void>
• Model._likeable.isLiked(id, userId): Promise<boolean>

Billable (when traits.billable: true) -- Stripe integration

All methods lazy-import @stacksjs/payments.

• createStripeUser(model, options), updateStripeUser(model, options), deleteStripeUser(model)
• createOrGetStripeUser(model, options), retrieveStripeUser(model)
• defaultPaymentMethod(model), setDefaultPaymentMethod(model, pmId), addPaymentMethod(model, paymentMethodId), paymentMethods(model, cardType?)
• newSubscription(model, type, lookupKey, options) -- returns { subscription, paymentIntent }
• updateSubscription(model, type, lookupKey, options), cancelSubscription(model, providerId, options)
• activeSubscription(model) -- queries subscriptions table for provider_status = 'active', then retrieves from Stripe
• checkout(model, priceIds[], options) -- supports enableTax, allowPromotions options
• createSetupIntent(model, options), subscriptionHistory(model), transactionHistory(model)

Two-Factor Auth (when traits.useAuth.useTwoFactor: true)

• Model._twoFactor.generateTwoFactorForModel(model) -- generates secret, calls model.update()
• Model._twoFactor.verifyTwoFactorCode(model, code): Promise<boolean>

Auto-Generated System Fields

• id -- primary key (auto-increment)
• created_at, updated_at -- when useTimestamps: true
• uuid -- when useUuid: true
• deleted_at -- when soft deletes enabled
• stripe_id -- when billable: true
• two_factor_secret, public_key -- when useAuth: { usePasskey: true }

Naming Conventions

• Model: PascalCase (ProductVariant)
• Table: snake_case plural (product_variants)
• Column: snake_case (first_name)
• Foreign key: {singular_model}_id (user_id)
• Pivot table: alphabetical sort of both table names (category_product)

ORM Utility Types (model-types.ts)

type Def<T> = T extends { getDefinition: () => infer D } ? D : never
type BelongsToForeignKeys<TDef>  // extracts { modelname_id: number } from belongsTo array
type ModelRow<T> = ModelAttributes<Def<T>> & BelongsToForeignKeys<Def<T>>
type NewModelData<T> = Partial<InferModelAttributes<Def<T>> & BelongsToForeignKeys<Def<T>>>
type UpdateModelData<T> = Partial<InferModelAttributes<Def<T>> & BelongsToForeignKeys<Def<T>>>

ORM Utility Functions (utils.ts)

• modelTableName(model: Model | string): Promise<string> -- uses model.table or converts model.name to snake_case plural
• getModelName(model, modelPath): string -- from definition or filename
• getTableName(model, modelPath): TableNames -- from definition or snake_case plural of name
• getPivotTableName(modelA, modelB): string -- alphabetical sort + join with _
• getRelations(model, name): Promise<RelationConfig[]> -- processes hasOne, hasMany, belongsTo, hasOneThrough, belongsToMany, morphOne
• getHiddenAttributes(attrs): string[] -- filters for hidden: true
• getGuardedAttributes(model): string[] -- filters for guarded: true, returns snake_case
• getFillableAttributes(model, relations): string[] -- filters for fillable: true, adds FK columns, stripe_id, uuid, etc.
• extractFields(model, file): Promise<ModelElement[]> -- parses model file for field metadata
• findCoreModel(name): string -- searches storage/framework/defaults/app/Models/ recursively
• findUserModel(name): string -- searches app/Models/
• fetchOtherModelRelations(modelName?): Promise<RelationConfig[]> -- scans all models for relations pointing to this model
• formatDate(date): string -- ISO format YYYY-MM-DD HH:MM:SS

Relationship Processing (utils.ts)

Each relationship type is processed into a RelationConfig object:

• hasOne / hasMany: FK = {parent_snake}_id, model key = {related_snake}_id
• belongsTo: FK is empty string (set on the owning model's side), supports custom foreignKey
• belongsToMany: the legacy array form auto-creates a conventional pivot and supports pivotTable, firstForeignKey, and secondForeignKey; the named object form supports table, foreignKey, relatedKey, and pivot metadata (columns, timestamps, uniques)
• hasOneThrough: includes throughModel and throughForeignKey
• morphOne: uses {modelName}able pattern, generates _type and _id columns

Named many-to-many relations are callable on model instances. Use their native relation builder for pivot writes:

const post = await Post.find(id)
await post.categories().sync(categoryIds)
await post.tags().attach(tagId)
await post.tags().detach()

Declaring custom pivot columns in the model is required when those columns have defaults that attach() and sync() must write. pivot.timestamps: true causes both timestamps to be generated and maintained.

Model Events (when traits.observe: true)

observe: true emits all three events. observe: ['create', 'update'] emits only those.

• '{modelname}:created' -- via afterCreate hook, lazy-imports @stacksjs/events
• '{modelname}:updated' -- via afterUpdate hook
• '{modelname}:deleted' -- via afterDelete hook

If @stacksjs/events is not available (browser, tests), errors are caught and silently ignored.

Stub Types in index.ts

The ORM exports stub types for commonly used models to keep typecheck green before code generation:

• UserModel, NewUser, User (class stub with static where, find, create, all)
• Job, FailedJob (query stubs)
• PaymentMethod (CRUD stubs)
• CategorizableTable, CategorizableModelsTable, CommentablesTable, TaggableTable

All 50+ Framework Models

Content: Author, Page, Post, Comment, Tag, Category Users: User, Customer, Driver, Subscriber, SubscriberEmail Commerce: Product, ProductVariant, ProductUnit, Cart, CartItem, Order, OrderItem, Coupon, GiftCard, Manufacturer, Review, LicenseKey, DigitalDelivery, WaitlistProduct, WaitlistRestaurant Payments: Payment, PaymentMethod, PaymentProduct, PaymentTransaction, Subscription, Transaction, Receipt Shipping: ShippingMethod, ShippingRate, ShippingZone, DeliveryRoute Loyalty: LoyaltyPoint, LoyaltyReward, TaxRate System: Job, FailedJob, Error, Log, Notification, Activity, Request, Websocket, PrintDevice Marketing: Campaign, EmailList, SocialPost

CLI Commands

• buddy migrate -- run pending migrations

Gotchas

• Models work directly via the dynamic ORM — no code generation step needed
• defineModel() calls createModel() from bun-query-builder at runtime, providing all typed query methods immediately
• Two ORM locations: storage/framework/core/orm/ (package) and storage/framework/orm/ (implementation)
• Factories use @stacksjs/faker -- each attribute can have a factory function
• The hidden attribute flag excludes fields from JSON serialization (e.g., passwords)
• The guarded flag prevents mass assignment
• The fillable flag explicitly allows mass assignment
• Pivot tables for belongsToMany are auto-created using alphabetical naming of both table names
• Model events are only emitted when observe: true (or array) trait is set
• The trait key for commentable is commentables (with 's'), not commentable
• Trait methods are accessed via underscore-prefixed properties: _taggable, _categorizable, _commentable, _billable, _likeable, _twoFactor
• The useAuth.useTwoFactor check (not usePasskey) determines if two-factor methods are added
• defineModel() calls createModel() from bun-query-builder which returns the typed query builder interface at runtime
• Model file loading uses findUserModel() (app/Models/) with fallback to findCoreModel() (storage/framework/defaults/app/Models/)
