Slug

Slug is an optional Pydantic field type — Annotated[str, BeforeValidator(...)] — that auto-slugifies any string assigned to the field. It is only available when pydantic is installed; otherwise it falls back to plain str.

from pydantic import BaseModel
from slugany import Slug

class Tag(BaseModel):
    name: str
    slug: Slug

tag = Tag(name="Machine Learning", slug="Machine Learning")
assert tag.slug == "machine-learning"

Slug: Any = Annotated[str, BeforeValidator(lambda v: slugify(v) if isinstance(v, str) else v)]
