Simple, secure math captcha for django forms
|Authors:||Justin Quick <firstname.lastname@example.org>|
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:
from math_captcha import MathCaptchaModelForm from myapp.models import Blog class MyExistingForm(MathCaptchaModelForm): # instead of forms.ModelForm #... extra fields here class Meta: model = Blog
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
A list of numbers to randomly choose from when generating the questions. Defaults to [1,2,3,4,5].
List of mathematical operators to use. Default is only add (+) and subtract (-). Available operators are: add (+), subtract (-), multiply (*), divide (/), and modulo (%)
Question that appears on forms as a label for math questions. By default it is 'Are you human?'
