Human readable captcha for z3cform
Project description
Introduction
collective.z3cform.norobots provides a “human” captcha widget based on a list of questions/answers.
This captcha can be used as a plone.app.discussiom captcha plugin.
The widget is based on z3c.form.TextWidget.
Requirements
tested with Plone 4.0 as a plugin for plone.app.discussion, should work with Plone 3
plone.app.z3cform
Installation
Just a simple easy_install collective.z3cform.norobots is enough.
Alternatively, buildout users can install collective.z3cform.norobots as part of a specific project’s buildout, by having a buildout configuration such as:
[buildout] ... eggs = collective.z3cform.norobots ... [instance] ... zcml = collective.z3cform.norobots
In portal_setup, apply the profile collective.z3cform.norobots:default.
Add a new question
In the Plone Property Sheet “norobots_properties” (portal_properties/norobots_properties), add a new property:
Name: The question id (ex: "question4") Value: your_question::the_answer (ex: "What is 10 + 12 ?::22") Type: string
Answer can contain multiple values delimited by semicolon:
Name: The question id (ex: "question8") Value: your_question::the_answer;another_answer (ex: "What is 5 + 5 ?::10;ten") Type: string
Usage
You can use this widget setting the “widgetFactory” property of a form field:
from zope import interface, schema from z3c.form import interfaces, form, field, button, validator from plone.app.z3cform.layout import wrap_form from collective.z3cform.norobots.i18n import MessageFactory as _ from collective.z3cform.norobots.widget import NorobotsFieldWidget from collective.z3cform.norobots.validator import NorobotsValidator class INorobotsForm(interface.Interface): norobots = schema.TextLine(title=_(u'Are you a human ?'), description=_(u'In order to avoid spam, please answer the question below.'), required=True) class NorobotsForm(form.Form): fields = field.Fields(INorobotsForm) fields['norobots'].widgetFactory = NorobotsFieldWidget # wrap the form with plone.app.z3cform's Form wrapper NorobotsFormView = wrap_form(NorobotsForm) # Register Norobots validator for the correponding field in the IContactInfo interface validator.WidgetValidatorDiscriminators(NorobotsValidator, field=INorobotsForm['norobots'])
for more information see contact_info.py in the plone_forms directory in the package.
Possible problems
I have the following error: “We already have: zope.schema 3.5.4 but z3c.form 2.4.1 requires ‘zope.schema>=3.6.0’.” => You should add this extra version restriction to your buildout: http://good-py.appspot.com/release/plone.app.z3cform/0.5.0
I have the following error when launching the tests: “ImportError: No module named lxml.html” => In order to run the tests you need lxml. You can add for example “z3c.form [test]” to your buildout. See http://plone.293351.n2.nabble.com/Custom-Dexterity-Widgets-td5594532.html for more details.
