Form mixin

CaptchaFormMixin adds the field and forwards the client IP. It uses the provider named by CAPTCHA_KIT["DEFAULT"], currently math.

The code

class ContactForm(CaptchaFormMixin, forms.Form):
        name = forms.CharField(max_length=100)
        email = forms.EmailField()
        message = forms.CharField(widget=forms.Textarea)


    def contact(request):
        form = ContactForm(request.POST or None, request=request)
        if request.method == "POST" and form.is_valid():
            ...

Passing request is optional. It forwards the client IP to the provider as remoteip, which the services use for risk scoring.
