Pydantic Tooltypes

TypeScript-like utilities for Pydantic models: Partial, Pick, Omit, and Required.

Features

• Partial: Makes all fields in a Pydantic model optional.
• Pick: Selects a subset of fields from a model.
• Omit: Removes a subset of fields from a model.
• Required: Makes selected fields required, others optional.

All utilities now support class parametrization, similar to generics in TypeScript or Python typing.

Installation

pip install pydantic-tooltypes

Usage

from pydantic import BaseModel
from pydantic_tooltypes import Partial, Pick, Omit, Required

class User(BaseModel):
    id: int
    email: str

# Partial: all fields optional
PartialUser = Partial[User]

# Pick: only selected fields included (and required)
PickUser = Pick[User, ['email']]

# Omit: all except the listed fields (the rest are required)
OmitUser = Omit[User, ['id']]

# Required: make some fields required over a Partial model
RequiredUser = Required[PartialUser, ['email']]
