WTForm generator for Pydantic

Overview

Form Generator
It is designed to work with Pydantic and WTForms. Especially useful with SQL Admin

Usage

Simple way:

from pydantic import BaseModel, Field
from formantic import Former

class User(BaseModel):
    id: int = Field(..., description="The unique identifier for the user")
    name: str = Field(..., description="The name of the user")
    email: str = Field(..., description="The email address of the user")

# WTForm based on Pydantic model
form = Former(User).gen_form()

form.process()

or with some additional modifications:

from pydantic import BaseModel, Field
from wtforms import StringField
from wtforms.form import BaseForm
from formantic import Former

class User(BaseModel):
    id: int = Field(..., description="The unique identifier for the user")
    name: str = Field(..., description="The name of the user")
    email: str = Field(..., description="The email address of the user")

# Form schema for BAseModel based on Pydantic model
form_schema = Former(User).gen_form_schema()

# Some additional field
form_schema["extra_field"] = StringField(
    "extra_field",
    description="An additional field not in the Pydantic model",
    default="Default Value"
)

form = BaseForm(form_schema)

form.process()

Then work with the form as with normal WTForms
