Simple, secure math captcha for django forms(Django 1.6+ compatible)
Project description
- Version:
- 0.1.2
Note: this includes an update to a deprecated import in the util.py file in order to make this Django 1.6+ compatible.
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.
Extending your forms:
from math_captcha import MathCaptchaModelForm
from myapp.forms import BlogForm
class MyExistingForm(BlogForm,MathCaptchaModelForm): # instead of forms.ModelForm
#... extra fields here
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.
Using with other apps
If you are running an app like, say django-contact-form and want to add math captcha here is how to go about it.
Add the following in your urls.py:
from contact_form.forms import ContactForm
from math_captcha.forms import MathCaptchaForm
class CaptchaContactForm(ContactForm,MathCaptchaForm):
pass
urlpatterns = patterns('',
...
url(r'^contact/$','contact_form.views.contact_form',{'form_class':CaptchaContactForm},name='contact_form'),
url(r'^contact/sent/$','django.views.generic.simple.direct_to_template',{ 'template': 'contact_form/contact_form_sent.html' },name='contact_form_sent'),
...
)
Now the contact form will block robots who cant do math.
