Captchas in a z3c form

Using quintagroup.z3cform.captcha in a z3c.form form is simple. Just add a Captcha field to your schema, use CaptchaWidgetFactory widget factory for this field and away you go:

    >>> from zope.interface import Interface
>>> from z3c.form import form, field
>>> from quintagroup.z3cform.captcha import Captcha
>>> from quintagroup.z3cform.captcha import CaptchaWidgetFactory

Now define form schema with Captch field

    >>> class ICaptchaSchema(Interface):
... captcha = Captcha(
... title=_(u'Type the code'),
... description=_(u'Type the code from the picture shown below.'))

And set proper widget factory for the captcha field

    >>>  class CaptchaForm(form.Form):
... fields = field.Fields(ICaptchaSchema)
... fields['captcha'].widgetFactory = CaptchaWidgetFactory

and z3c.form will take care of the rest. The widget associated with this field will render the captcha and verify the use input automatically.
