django-math-captcha is an easy way to add mathematical captcha verification to your already existing forms. It asks you a simple math question (eg '1 + 2 =') and validates the form if your response is correct. All you have to do is subclass either MathCaptchaForm or MathCaptchaModelForm in your own forms.

Use it in your forms:

Now you can be certain that the only users who create blogs are humans

Check out the example project for more practical use and tests.

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

MATH_CAPTCHA_NUMBERS

A list of numbers to randomly choose from when generating the questions. Defaults to [1,2,3,4,5].

MATH_CAPTCHA_OPERATORS

List of mathematical operators to use. Default is only add (+) and subtract (-). Available operators are: add (+), subtract (-), multiply (*), divide (/), and modulo (%)

MATH_CAPTCHA_QUESTION

Question that appears on forms as a label for math questions. By default it is 'Are you human?'

Use it in your forms:

*from math_captcha import MathCaptchaModelForm*

from myapp.models import Blog

class MyExistingForm(MathCaptchaModelForm): # instead of forms.ModelForm

#... extra fields here

class Meta:

model = Blogfrom myapp.models import Blog

class MyExistingForm(MathCaptchaModelForm): # instead of forms.ModelForm

#... extra fields here

class Meta:

model = Blog
