Very Simple Math Captcha is the easiest way to add mathematical captcha verification to your forms. It asks you a simple math question (eg 1 + 2 =) and validates the form if your response is correct and you can be certain that the users are humans.

Using with other apps

Add the following in your views.py:

from verysimplemathcaptcha import VerySimpleMathCaptcha
        
def some_page(request):
	CaptchaObject = VerySimpleMathCaptcha()
	if form.is_valid() and CaptchaObject.isValid(request.POST['captcha_id'], request.POST['captcha_answer']):
		pass

Now the contact form will block robots who cant do math.

Settings

Set the behavior of the math captcha interaction in your settings.py

VERYSIMPLEMATHCAPTCHA_USING_PIL = True

MATH_CAPTCHA_QUESTION = 'Are you human?'
