Using Anti Captcha

The anti captcha of fighting spam technique is described in detail here: http://blog.fili.nl/articles/the-anti-captcha-challenge/ . The technique implemented in this library is similar. You can add anti captcha capability to any form you want simply by decorating your form.:

from django import forms
from anti_spam.decorators import anticaptcha


@anticaptcha
class MyContactForm(forms.Form):
    ...

Using Akismet

To add Akismet spam checking to your form you will need to:

1. Get a Wordpress API key from wordpress.com and add it to a variable called AKISMET_API_KEY in settings.py:

   AKISMET_API_KEY = 'key_here'
   

2. Decorate your form class and tell it which fields to check for spam:

   @akismet(fields=['body'])
   class ContactForm(forms.Form):
       email = forms.EmailField()
       body = forms.CharField(widget=forms.Textarea())
   

3. Add a request argument to form instantiation. So if you previously had

   form = ContactForm(request.POST)
   

Replace it with:

form = ContactForm(request.POST, request=request)
