Features

• Type-safe validated data via AirForm[MyModel] generic parameter
• Works with AirModel (database-backed forms) and plain BaseModel (contact forms, search, etc.)
• Reads the full AirField metadata vocabulary: Widget, Label, Placeholder, HelpText, Choices, Autofocus, PrimaryKey, Hidden, ReadOnly
• Auto-skips PrimaryKey and Hidden("form") fields in rendered output
• HTML5 validation attributes from Pydantic constraints (minlength, maxlength, required)
• Accessible by default: aria-invalid, aria-describedby, role="alert" on errors
• Textarea, select, and checkbox rendering from type annotations and metadata
• Zero-config CSRF protection: render() embeds a signed token, validate() checks it
• Swappable widget for custom renderers
• from_request() for async ASGI request handling (works with FastAPI Depends)

Quick start

Database-backed form (most common)

from airmodel import AirModel, AirField
from airform import AirForm
import air

app = air.Air()

class BookOrder(AirModel):
    id: int | None = AirField(default=None, primary_key=True)
    title: str = AirField(label="Book Title", min_length=1)
    quantity: int = AirField(label="Quantity")

class BookOrderForm(AirForm[BookOrder]):
    pass

@app.page
def order_page(request: air.Request):
    return air.Html(
        air.H1("Order a Book"),
        air.Form(
            air.Raw(BookOrderForm().render()),
            air.Button("Order", type_="submit"),
            method="post", action="/order",
        ),
    )

@app.post("/order")
async def submit_order(request: air.Request):
    form = await BookOrderForm.from_request(request)
    if form.is_valid:
        await BookOrder.create(
            title=form.data.title,
            quantity=form.data.quantity,
        )
        return air.Html(air.H1(f"Ordered: {form.data.title}"))
    return air.Html(
        air.Form(
            air.Raw(form.render()),
            air.Button("Order", type_="submit"),
            method="post", action="/order",
        ),
    )

Plain form (no database)

from pydantic import BaseModel
from airfield import AirField
from airform import AirForm

class ContactMessage(BaseModel):
    name: str = AirField(label="Name", autofocus=True)
    email: str = AirField(type="email", label="Email")
    message: str = AirField(widget="textarea", label="Message")

class ContactForm(AirForm[ContactMessage]):
    pass

form = ContactForm()
form.validate({"name": "Audrey", "email": "[e-mail]", "message": "Hello!"})
if form.is_valid:
    send_email(form.data.name, form.data.email, form.data.message)

html = ContactForm().render()
