collective.z3cform.norobots 1.4.1

Human readable captcha for z3cform

Latest Version: 1.4.2.2

Overview

collective.z3cform.norobots provides a "human" captcha widget based on a list of question/answer(s).

This captcha can be used as a plone.app.discussion (Plone Discussions) captcha plugin and in all z3c forms.

The widget is based on z3c.form.TextWidget.

Since version 1.4, questions configuration uses a dedicated control panel (using plone.app.registry) instead of a simple properties sheet. An upgrade step provides migration from earlier versions.

Interface is translated in the following languages: Czech [cs], Danish [da], German [de], Basque [eu], Suomeksi [fi], French [fr] and Simplified Chinese [zh_CN]. => Some strings have been added in 1.4, need to be translated.

Requirements

  • I have tested with Plone 4.1.5 and Plone 4.0.10 (http://plone.org/products/plone).
  • For Plone 4.0 : plone.app.z3form, plone.app.registry, and plone.app.discussion to use the captcha for anonymous comments in Plone Discussions. See bellow.

Installation

Getting the module

Add collective.z3cform.norobots to your plone.recipe.zope2instance buildout section e.g.:

[instance]
...
eggs =
    Plone
    ...
    collective.z3cform.norobots

...

zcml =
    ...
    collective.z3cform.norobots

Or, you can add it as a dependency on your own product setup.py:

install_requires=[
    ...
    'collective.z3cform.norobots',
],

Enabling the module

For Plone 4.1.x:

  • In the Addons control panel, install "Norobots captcha field (collective.z3cform.norobots)".

For Plone 4.0.x:

Add a new question

In the "Norobots widget settings" control panel, add a new line in the field "Norobots question::answer":

your_question::the_answer

Example : What is 10 + 12 ?::22

Answer can contain multiple values delimited by semicolon:

your_question::the_answer;another_answer

Example : What is 5 + 5 ?::10;ten

Quickly test ?

Download collective.z3cform.norobots and use virtualenv and buildout to test the module:

easy_install virtualenv
cd collective.z3cform.norobots
virtualenv .
source bin/activate
(collective.z3cform.norobots) easy_install zc.buildout
!!! check the buildout content before running !!!
(collective.z3cform.norobots) ln -s test-plone-4.1.x.cfg buildout.cfg
(collective.z3cform.norobots) python bootstrap.py
(collective.z3cform.norobots) bin/buildout
[...] be patient... [...]
(collective.z3cform.norobots) ./bin/instance fg

Go to http://localhost:8080, add a new Plone Site and install collective.z3cform.norobots (see above).

Launch tests:

(collective.z3cform.norobots) ./bin/test -s collective.z3cform.norobots

Usage in a z3c form

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.
