Models
Models represent database tables and are the primary interface for reading and writing data. Each model maps to a single table and exposes an async query builder.
Defining a Model
Extend Model from fastapi_startkit.masoniteorm and annotate your columns as class-level type hints:
from fastapi_startkit.masoniteorm import Model
class User(Model):
__table__ = "users"
id: int
name: str
email: str__table__
By default the ORM infers the table name from the class name (pluralized, snake_cased). Set __table__ explicitly to override:
class PostTag(Model):
__table__ = "post_tag"__timestamps__
Timestamp columns (created_at, updated_at) are managed automatically. Set __timestamps__ = False to disable them:
class PostTag(Model):
__table__ = "post_tag"
__timestamps__ = FalseQuerying
All query methods are async and must be awaited.
Fetch all records
users = await User.all()Fetch the first record
user = await User.first()Find by primary key
user = await User.find(1)Filter with where
user = await User.where("email", "admin@example.com").first()get() — execute a query
posts = await Post.where("user_id", 1).get()find_or_fail(id) — find or raise
Fetch a record by primary key, raising ModelNotFoundException if nothing is found:
user = await User.find_or_fail(1)first_or_fail() — first or raise
Execute the current query and raise ModelNotFoundException if no record matches:
user = await User.where("email", "admin@example.com").first_or_fail()exists() — check existence
Return True if any record matches the current query, False otherwise:
active = await User.where("is_active", True).exists()count() — row count
Return the number of rows matching the current query:
total = await User.count()
active_count = await User.where("is_active", True).count()paginate(per_page, page) — paginate results
Return a LengthAwarePaginator containing the requested slice of records plus total-count metadata:
page = await User.paginate(per_page=15, page=1)
# page.items → list of User instances
# page.total → total number of matching rows
# page.last_page → last available page numberor_where / where_raw / or_where_raw / or_where_null — raw & OR variants
# OR condition
users = await User.where("role", "admin").or_where("role", "moderator").get()
# Raw SQL predicate
users = await User.where_raw("created_at > NOW() - INTERVAL '7 days'").get()
# Raw SQL with OR
users = await User.where("is_active", True).or_where_raw("role = 'superadmin'").get()
# OR IS NULL
users = await User.where("name", "Alice").or_where_null("deleted_at").get()Creating Records
create
Insert a new record and return the model instance:
post = await Post.create(
user_id=user.id,
title="Hello World",
content="My first post."
)first_or_create
Fetch a matching record or create it if it does not exist. The first dict is the lookup condition, the second is the data to merge on create:
user = await User.first_or_create(
{"email": "admin@example.com"},
{"name": "Admin User", "password": "secret"}
)insert — bulk insert rows
Insert one or many rows without instantiating individual model instances:
await User.insert({"email": "picard@example.com", "votes": 0})
await User.insert([
{"email": "picard@example.com", "votes": 0},
{"email": "janeway@example.com", "votes": 0},
])Unlike
create,insertdoes not fire model events, apply timestamps, or return model instances. It is intended for high-volume seed and batch operations.
Updating Records
user = await User.find(1)
user.name = "Jane Doe"
await user.save()Deleting Records
user = await User.find(1)
await user.delete()Accessing Attributes
Model attributes map directly to column names:
user = await User.first()
print(user.id)
print(user.name)
print(user.email)
print(user.created_at.diff_for_humans()) # pendulum datetimeComplete Example
The Post model from the example app shows columns and relationships together:
# app/models/post.py
from typing import TYPE_CHECKING
from fastapi_startkit.masoniteorm import Model
from fastapi_startkit.masoniteorm.relationships import BelongsTo, HasMany, BelongsToMany
if TYPE_CHECKING:
from app.models.user import User
from app.models.tag import Tag
from app.models.media import Media
class Post(Model):
__table__ = "posts"
id: int
user_id: int
title: str
content: str
author: "User" = BelongsTo('User', local_key='user_id', foreign_key="id")

tags: list["Tag"] = BelongsToMany("Tag", "post_id", "tag_id", table="post_tag")Relationship declarations are covered in the Relationships section.
Automatic type coercion and custom value objects are covered in the Casts section.
