• 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
• Swappable widget for custom renderers
• from_request() for async ASGI request handling (works with FastAPI Depends)

Quick start

With Air

from air import AirForm, AirModel, AirField
import air

app = air.Air()

class Contact(AirModel):
    name: str
    email: str = AirField(type="email", label="Email Address")

class ContactForm(AirForm[Contact]):
    pass

@app.post("/contact")
async def submit(request: air.Request):
    form = await ContactForm.from_request(request)
    if form.is_valid:
        return air.Html(air.H1(f"Thanks, {form.data.name}!"))
    return air.Html(air.Raw(form.render()))

Standalone (any ASGI framework)

from pydantic import BaseModel
from airform import AirForm

class ContactModel(BaseModel):
    name: str
    email: str

class ContactForm(AirForm[ContactModel]):
    pass

# Validate
form = ContactForm()
form.validate({"name": "Audrey", "email": "[e-mail]"})
if form.is_valid:
    print(form.data.name)  # type-safe: editor knows this is str

# Render
html = ContactForm().render()
