Easy-to-use django captcha or registration app with captcha?
I want开发者_开发知识库 to implement user registration using captcha in Django. The workflow of django-registration app is a great, but it doesn't have captcha.
What captcha would you recommend to use with it? Are there some other variants of registration+captcha or useful links on the topic?
This should work with Django-1.1 and don't be too hard to install.
django-registration is pretty extendable. One way to extend it is to provide a custom registration form. I'd recommend to use reCaptcha, e.g. with the widget and form field from here (archived). Then it is as simple as writing a custom form class and registration backend (which is simpler than it sounds):
from registration.backends.default import DefaultBackend
from registration.forms import RegistrationForm
class RecaptchaRegistrationForm(RegistrationForm)
recaptcha = ReCaptchaField(label="I'm a human")
class RecaptchaRegistrationBackend(DefaultBackend):
def get_form_class(self, request):
return RecaptchaRegistrationForm
The last step is to tell django-registration to use your backend. That step is described in the docs (I couldn't find a HTML version of the docs, sorry)
I've just had this problem, but the solution is dead simple.
I'm using django-registration, and I want a reCAPTCHA field for user registration. In just 1 minute:
download django-recaptcha (
pip install django-recaptcha
)install it on your project. That is, copy the "captcha" folder to your project, add "captcha" to
INSTALLED_APPS
and add yourRECAPTCHA_PUBLIC_KEY
andRECAPTCHA_PRIVATE_KEY
keys to settings.py too (as described in the installation instructions)open
registration/forms.py
and add this field insideclass RegistrationForm(forms.Form):
captcha = ReCaptchaField()
you will also have to import:
from captcha.fields import ReCaptchaField
And that's it. Less than a minute.
For those like me arriving late to the thread, there are a bunch of solutions out there now, which are pretty easy to install:
- http://code.google.com/p/django-simple-captcha/
- http://code.google.com/p/django-captcha/
- https://github.com/inueni/django-captcha-field
- https://github.com/justquick/django-math-captcha
- https://github.com/marconi/django-mollom which uses the third-party Mollom service (which provides captcha and spam-filtering services).
I've successfully setup Django Mollom and Django Simple Captcha, and the hardest part was yak shaving around installing PIL on my Mac. Implementing the code was as straightforward as the docs for each would suggest.
