First Form

First Type

Below is an example of a form named "Book" that contains (2) two fields

• title
• author

Just like our First Type.

Form

apps/demo/forms.py

# -*- coding: utf-8 -*-
"""
    { Forms } for GraphQL
"""
import fastberry as fb

# Create Group "Form"
form = fb.input("form")

# Create your <forms> here.
@form
class Book:
    """(FormBook) Read The Docs"""

    title = fb.value(
        str,
        default=None,
        required=True
    )
    author = fb.value(
        str,
        default=None,
        required=True
    )
