Django add an attribute class form in init.py

Question

My form class

from django import forms

class Form(forms.Form):
    your_name = forms.CharField(label='Your name ', max_length=100)

My app file __init__.py

from django import forms
from my_app.forms import Form
from captcha.fields import ReCaptchaField

def register(form):
 form.captcha=CaptchaField()

register(Form)

Code in __init__.py add an attribute captcha but it is not on the page.

I tried so

My form class

from django import forms

class Form(forms.Form):
    your_name = forms.CharField(label='Your name ', max_length=100)
    captcha=CaptchaField()

It works, but I have a different! I want to add a сaptcha many forms. I want to add the captcha without changing the form classes. I want to change the form classes during initialization. How to do it???

Would a superclass (subclass of django.forms.Form) with the captcha attribute solve your problem? — Mause

You need to assign the field to form.fields, not just form.

However this is not really the way to do this. Instead, you should make all your forms inherit from a shared parent class, which defines the captcha field.

It works MyForm.base_fields['foo'] = CharField(max_length=100)

Continuing from a comment, have a base class inherit from django.forms.Form, and subclass it for all the forms you want a captcha field on;

from captcha.fields import ReCaptchaField
from django.forms import Form

class CaptchaMixin():
    captcha = ReCaptchaField()

class ActualForm(CaptchaMixin, Form):
    pass
