Introduction

This Plone package is aimed for developers who want to create forms in Python code.

Please read the documentation for z3c.form, which contains important information about using z3c.form in Zope 2 in general. For the most part, that package contains the “active” parts that you need to know about, and this package provides “passive” overrides that make the forms integrate with Plone.

Features

The following Plone and z3c.form integration is added

• Plone main_template.pt integration

• Plone specific widget frame

• Date/time pickers

• WYSIWYG widget (TinyMCE visual editor with Plone support)

• CRUD forms

Out of the box form templates

The form and widget templates are applied in the following order

• plone.app.z3cform specific

• plone.z3cform specific

• z3c.form specific

plone.app.z3cform package overrides the @@ploneform-macros view from plone.z3cform, using standard Plone markup for form fields, fieldsets, etc.

All the macros described in plone.z3cform are still available. In addition, you can use the widget_rendering macro to render all the default widgets, but none of the fieldsets (groups) or the fieldset headers (which would be rendered with the fields macro).

Each widget is rendered using the @@ploneform-render-widget view, which by default includes the widget’s label, required indicator, description, errors, and the result of widget.render(). This view may be overridden for particular widget types in order to customize this widget chrome.

Customizing form behavior

Form method

If your form instance defines a property called method it allows you to set whether form is HTTP POST or HTTP GET. The default is POST. This translates to <form method="post"> attribute.

Example:

class HolidayServiceSearchForm(form.Form):
        """ Example search form of which results can be bookmarked.

        Bookmarking is possible because we use HTTP GET method.
        """

        method = "get"

Form action

Form action property defines HTTP target where the form is posted. The default is the same page where the form was rendered, request.getURL().

Example:

class HolidayServiceSearchForm(form.Form):

    def action(self):
        """ Redefine <form action=''> attribute.

        We use URL fragment to define the <a> anchor
        were we directly scroll at the results when the form is posted,
        skipping unnecessary form fields part. The user can scroll
        back there if he/she wants modify the parameters.
        """

        # Context item URL + form view name + link fragment.
        # This works for HTTP GET forms only.
        # Note that we cannot use request.getURL() as it might contain
        # 1) prior fragment 2) GET query parameters messing up the UrL
        return self.context.absolute_url() + "/holidayservice_view" + "#searched"

Fieldsets and tabs

You can fieldsets to your form if you subclass the form from z3c.form.group.GroupForm. The default behavior of Plone is to turn these fieldsets to tabs (as seen on any Edit view of content item).

You can disable this behavior for your form:

class ReportForm(z3c.form.group.GroupForm, z3c.form.form.Form):

    # Disable turn fieldsets to tabs behavior
    enable_form_tabbing  = False

Unload protection

The default behaviour on Plone is to add a confirm box if you leave a form you have modified without having submitted it.

You can disable this behavior for your form:

class SearchForm(z3c.form.group.GroupForm, z3c.form.form.Form):

    # Disable unload protection behavior
    enable_unload_protection  = False

Autofocus

The default behaviour on Plone Forms is to use the formautofocus pattern to focus the “first” input field.

You can disable this behavior for your form:

class SearchForm(z3c.form.group.GroupForm, z3c.form.form.Form):

    # Disable autofocus behavior
    enable_autofocus = False

CSRF Protection

A common vulnerability affecting web forms is cross-site request forgery (CSRF). This attack occurs when the user of your site visits a third-party site that uses Javascript to post to a URL on your site without the user’s knowledge, taking advantage of the user’s active session.

plone.app.z3cform can protect against this type of attack by adding a unique token as a hidden input when rendering the form, and checking to make sure it is present as a request parameter when form actions are executed.

To turn on this protection, enable the form’s enableCSRFProtection attribute. Example:

class PasswordForm(form.Form):
    """Form to set the user's password."""
    enableCSRFProtection = True

Form main template override

Forms are framed by FormWrapper views. It places rendered form inside Plone page frame. The default FormWrapper is supplied automatically, but you can override it.

Below is a placeholder example with few <select> inputs.

Example reporter.py:

from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile as FiveViewPageTemplateFile
from zope.i18nmessageid import MessageFactory
from zope.schema.vocabulary import SimpleTerm
from zope.schema.vocabulary import SimpleVocabulary

import plone.app.z3cform
import plone.z3cform.templates
import z3c.form
import zope.interface
import zope.schema

_ = MessageFactory('your.addon')


def make_terms(items):
    """ Create zope.schema terms for vocab from tuples """
    terms = [SimpleTerm(value=pair[0], token=pair[0], title=pair[1]) for pair in items]
    return terms


output_type_vocab = SimpleVocabulary(make_terms([("list", "Patient list"), ("summary", "Summary")]))


class IReportSchema(zope.interface.Interface):
    """ Define reporter form fields """
    outputType = zope.schema.Choice(
        title=u"Output type",
        description=u"How do you want the output",
        source=output_type_vocab)

    country = zope.schema.Choice(
        title=u"Country",
        required=False,
        description=u"Which country to report",
        vocabulary="allowed_countries")

    hospital = zope.schema.Choice(
        title=u"Hospital",
        required=False,
        description=u"Which hospital to report",
        vocabulary="allowed_hospitals")


class ReportForm(z3c.form.form.Form):
    """ A form to output a HTML report from chosen parameters """

    fields = z3c.form.field.Fields(IReportSchema)

    ignoreContext = True

    output = None

    @z3c.form.button.buttonAndHandler(_('Make Report'), name='report')
    def report(self, action):
        data, errors = self.extractData()
        if errors:
            self.status = "Please correct errors"
            return

        # Create sample item which we can consume in the page template
        self.output = dict(country="foobar")

        self.status = _(u"Report complete")


# IF you want to customize form frame you need to make a custom FormWrapper view around it
# (default plone.z3cform.layout.FormWrapper is supplied automatically with form.py templates)
report_form_frame = plone.z3cform.layout.wrap_form(ReportForm, index=FiveViewPageTemplateFile("templates/reporter.pt"))

Example configure.zcml:

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:browser="http://namespaces.zope.org/browser"
    i18n_domain="your.addon">

   <browser:page
       for="*"
       name="reporter"
       class=".reporter.report_form_frame"
       permission="zope2.View"
       />

</configure>

Example templates/reporter.html:

<html metal:use-macro="context/main_template/macros/master"
      i18n:domain="sits.reporttool">
<body>
    <metal:block fill-slot="main">

        <h1 class="documentFirstHeading" tal:content="view/label | nothing" />

        <div id="content-core">
            <div id="form-input">
                <span tal:replace="structure view/contents" />
            </div>
            <div id="form-output" tal:condition="view/form_instance/output">
                Chosen country: <b tal:content="view/form_instance/output/country" />
            </div>
        </div>

    </metal:block>
</body>
</html>

Widget frame override

You can override widget templates as instructed for z3c.form. plone.app.z3cform renders a frame around each widget which usually consists of

• Label

• Required marker

• Description

You might want to customize this widget frame for your own form. Below is an example how to do it.

Copy widget.pt to your own package and customize it in way you wish

Add the following to configure.zcml

<browser:page
    name="ploneform-render-widget"
    for=".demo.IDemoWidget"
    class="plone.app.z3cform.templates.RenderWidget"
    permission="zope.Public"
    template="demo-widget.pt"
    />

Create a new marker interface in Python code

from zope.interface import Interface

class IDemoWidget(Interface):
    pass

Then apply this marker interface to all of your widgets in form.update()

from zope.interface import alsoProvides

class MyForm(...):
    ...
    def update(self):
        super(MyForm, self).update()
        for widget in form.widgets.values():
            alsoProvides(widget, IDemoWidget)

Hide fields that have no value

The .empty css class marks the fields that have no value. If you don’t want to display these fields in view mode, add the following css in your theme.

.template-view .empty.field {
   display: none;
}

Add additional parameters to widgets

You can add additional parameters to widgets defined in this package via the plone.autoform.widgets.ParameterizedWidget.

from plone.app.z3c.form.widget import DateWidget
MyDateWidget = ParameterizedWidget(DateWidget, wrapper_css_class='event_start')

or via directives

from plone.app.z3c.form.widget import DateWidget


@provider(IFormFieldProvider)
class IMyEventBehavior(model.Schema):

...
    widget('event_start', DateWidget, wrapper_css_class='event_start')
    event_start = schema.TextLine(
        title=_(u'label_event_start'),
        description=_(u'help_event_start'),
        required=True,
    )

Testing

To test plone.app.z3form it is recommended to use plone.app.testing function test layer which will do plone.app.z3cform setup for you. Read plone.app.z3cform manual for further instructions.

If you still need to test forms on lower level in unit tests you need to enable plone.app.z3cform support manually. Below is an example:

import unittest

from zope.interface import alsoProvides
from zope.publisher.browser import setDefaultSkin

from z3c.form.interfaces import IFormLayer

class TestFilteringIntegration(unittest.TestCase):
    """ Test that filtering options work on the form """

    layer = MY_TEST_LAYER_WITH_PLONE

    def setUp(self):
        super(TestFilteringIntegration, self).setUp()
        request = self.layer["request"]
        setDefaultSkin(request)
        alsoProvides(request, IFormLayer) #suitable for testing z3c.form views

    def test_report_form_filtering(self):
        reporter = ReportForm(self.layer["portal"], self.layer["request"])
        reporter.update()

Troubleshooting

Here are some common errors you might encounter with plone.app.z3cform.

ComponentLookupError in updateWidgets()

plone.app.z3cform layers are not in place (configuration ZCML is not read). You probably forgot to include plone.app.z3cform in your product’s configuration.zcml. See Installation above.

Inline validation

First, let’s set up some infrastructure:

>>> from zope.interface import alsoProvides
>>> from plone.testing.zope import makeTestRequest
>>> from zope.annotation.interfaces import IAttributeAnnotatable
>>> from z3c.form.interfaces import IFormLayer

>>> app = layer['app']
>>> def make_request(form=None, lang='en'):
...     request = makeTestRequest({'HTTP_ACCEPT_LANGUAGE': lang})
...     if form is None:
...         form = {}
...     request.form.update(form)
...     alsoProvides(request, IFormLayer)
...     alsoProvides(request, IAttributeAnnotatable)
...     return request

Then we create a simple z3c form

>>> from zope import interface, schema
>>> from z3c.form import form, field, button
>>> from plone.z3cform.layout import FormWrapper

>>> class MySchema(interface.Interface):
...     age = schema.Int(title=u"Age")

>>> from __future__ import print_function
>>> class MyForm(form.Form):
...     fields = field.Fields(MySchema)
...     ignoreContext = True # don't use context to get widget data
...
...     @button.buttonAndHandler(u'Apply')
...     def handleApply(self, action):
...         data, errors = self.extractData()
...         print(data['age'])  # ... or do stuff

>>> class MyFormWrapper(FormWrapper):
...     form = MyForm
...     label = u"Please enter your age"

>>> from zope.component import provideAdapter
>>> from zope.publisher.interfaces.browser import IBrowserRequest
>>> from zope.interface import Interface

>>> provideAdapter(adapts=(Interface, IBrowserRequest),
...                provides=Interface,
...                factory=MyFormWrapper,
...                name=u"test-form")

Let’s verify that worked:

>>> from zope.component import getMultiAdapter
>>> from zope.interface import Interface, implementer
>>> from Acquisition import Implicit
>>> @implementer(Interface)
... class Bar(Implicit):
...     def restrictedTraverse(self, name):
...         # fake traversal to the form
...         if name.startswith('@@'):
...             return getMultiAdapter((self, self._REQUEST), Interface, name[2:])
...         else:
...             return getattr(self, name)
...
>>> context = Bar()
>>> request = make_request()
>>> context._REQUEST = request # evil test fake
>>> formWrapper = getMultiAdapter((context, request), name=u"test-form")
>>> formWrapper
<Products.Five...MyFormWrapper object ...>
>>> formWrapper.form
<class 'plone.app.z3cform.tests.example.MyForm'>

>>> del context, request

Inline validation

Inline validation is invoked via the @@z3cform_validate_field view.

>>> context = Bar()
>>> request = make_request(form={'form.widgets.age': 'Title'})
>>> context._REQUEST = request
>>> form = MyForm(context, request)
>>> z3cform_validate_field = getMultiAdapter((form, request), name=u"z3cform_validate_field")

This is wired up with jQuery. When the user leaves a form control with inline validation enabled, it will be called with the following parameters:

>>> z3cform_validate_field(fname=u'form.widgets.age')
'{"errmsg": "The entered value is not a valid integer literal."}'

>>> request = make_request(form={'form.widgets.age': '20'})
>>> context._REQUEST = request
>>> form = MyForm(context, request)
>>> z3cform_validate_field = getMultiAdapter((form, request), name=u"z3cform_validate_field")
>>> z3cform_validate_field(fname=u'form.widgets.age')
'{"errmsg": ""}'

If the field name (fname) is not provided by the client, the validation should return without issue:

>>> z3cform_validate_field()
'{"errmsg": ""}'
>>> z3cform_validate_field(fname=None)
'{"errmsg": ""}'

Inline validation with groups

We use plone.app.z3cform.tests.example.MyGroupFormWrapper and validate the field ‘name’ that’s part of a group. Inline validation is invoked via the @@z3cform_validate_field view.

>>> request = make_request(form={'form.widgets.name': ''})
>>> context._REQUEST = request
>>> from plone.app.z3cform.tests.example import MyGroupFormWrapper
>>> form = MyGroupFormWrapper(context, request)
>>> z3cform_validate_field = getMultiAdapter((form, request), name=u"z3cform_validate_field")

The validation view takes an Attribute fset with ether the numeric index or the name of the group.

>>> z3cform_validate_field(fname=u'form.widgets.name', fset="0")
'{"errmsg": "Required input is missing."}'
>>> z3cform_validate_field(fname=u'form.widgets.name', fset="mygroup")
'{"errmsg": "Required input is missing."}'

>>> request = make_request(form={'form.widgets.name': u'Name'})
>>> context._REQUEST = request
>>> form = MyGroupFormWrapper(context, request)
>>> z3cform_validate_field = getMultiAdapter((form, request), name=u"z3cform_validate_field")
>>> z3cform_validate_field(fname=u'form.widgets.name', fset="0")
'{"errmsg": ""}'
>>> z3cform_validate_field(fname=u'form.widgets.name', fset="mygroup")
'{"errmsg": ""}'

Inline-Validation and Translation of ErrorSnippets

We use plone.app.z3cform.tests.example.MyGroupFormWrapper and validate the field ‘name’ that’s part of a group. Inline validation is invoked via the @@z3cform_validate_field view.

>>> request = make_request(form={'form.widgets.name': ''}, lang='de',)
>>> context._REQUEST = request
>>> form = MyGroupFormWrapper(context, request)
>>> z3cform_validate_field = getMultiAdapter((form, request), name=u"z3cform_validate_field")

The validation view takes an Attribute fieldset with the index of the group. The error is only shown when warning_only is explicitly switched off (matching the behavior of archetypes.)

>>> z3cform_validate_field(fname=u'form.widgets.name', fset="0")
'{"errmsg": "Erforderliche Eingabe fehlt."}'

Forms embedded inside normal views

It’s possible to embed z3c.form Forms inside a normal BrowserView via viewlets, portlets or tiles.

Currently the name of the form to be validated is gotten from the URL. For embedded forms this can’t work since the URL only has the containing view’s name.

Until a lasting solution is found, we just make sure that validation doesn’t raise an exception if it receives a normal browerview as the supposed form.

>>> from zope.publisher.browser import BrowserView
>>> class MyNormalView(BrowserView):
...     """ """

>>> provideAdapter(adapts=(Interface, IBrowserRequest),
...                provides=Interface,
...                factory=MyNormalView,
...                name=u"my-view")

Let’s verify that it gets called…

>>> context = Bar()
>>> request = make_request()
>>> view = getMultiAdapter((context, request), name=u"my-view")
>>> view
<MyNormalView object ...>

Inline validation is invoked via the @@z3cform_validate_field view. But in this case no validation output should be returned.

>>> context = Bar()
>>> request = make_request(form={'form.widgets.age': 'Title'})
>>> z3cform_validate_field = getMultiAdapter((view, request), name=u"z3cform_validate_field")
>>> z3cform_validate_field(fname=u'form.widgets.age')
'{"errmsg": ""}'

Changelog

4.7.0 (2024-09-24)

New features:

• Implement new ContentBrowserWidget for pat-contentbrowser pattern.

  The deprecated RelatedItemsWidget and pat-relateditems pattern is still available and imports should not break. But the default widget and converter adapter registration for z3c.relationfield is changed to the new widget.

  Since plone.app.relationfield defines the widget with plone.autoform schema hints nothing changes until the package is updated to the new widget. [petschki] (#197)

4.6.1 (2024-05-30)

Internal:

• Date/time widget: Fix data converter adaption. Get the data converter for the date and datetime widgets via adaption and remove the _converter attribute hack. This aligns the code to z3c.form standards and allows to override the data converter which was previously not easily possible. [thet] (#204)

4.6.0 (2024-04-22)

New features:

• Use label_css_class attribute from widget if available in checkbox_input & radio_input [MrTango] (#202)

4.5.0 (2024-03-19)

New features:

• Add support for the “accept” attribute on file inputs.

  If the widget’s field - if there is one - has the “accept” attribute set (the NamedImage field has image/* set by default) then this is rendered as an accept attribute on the file input.

  This would restrict the allowed file types before uploading while still being checked on the server side.

3.0 (2017-03-28)

Breaking changes:

• Removed plone.app.z3cform.object and plone.app.z3cform.objectsubform because z3c.form 3.3 removed the underlying code. See https://github.com/zopefoundation/z3c.form/pull/38 for upstream changes. [maurits]

2.1.2 (2016-12-02)

Bug fixes:

• Remove ZopeTestCase. [ivanteoh, maurits]

• In select widget, accept items as property or method. This avoids breaking on some z3c.form versions. See https://github.com/zopefoundation/z3c.form/issues/44 [maurits]

2.1.1 (2016-09-16)

Bug fixes:

• Enable unload protection by using pattern class pat-formunloadalert instead enableUnloadProtection. [thet]

2.1 (2016-08-12)

New features:

• Related items data converter supports explicit value_type specified in field when using collections of UUID values. This is backward-compatible with previous conversion to field values, supports str/unicode value(s), whichever is specified by field. [seanupton]

• Support functions as values in the pattern_options dictionary, which gets then serialized to JSON. Before that, walk recursively through pattern_options and call all functions with the widgets context. This allows for context-specific, runtime evaluated pattern option values. [thet]

• Don’t overwrite widget default css classes when rendering pattern widgets. This allows setting a css class via the klass keyword in plone.autoform widget directives. [thet]

2.0.0 (2016-04-29)

Incompatibilities:

• Fix inline-validation warning error [jbirdwell]

• Use ViewPageTemplateFile from zope.browserpage. [hannosch]

0.5.8 (2012-05-07)

• Prevent empty error divs from being generated if errors are already associated with a field. [davidjb]

0.5.7 - 2011-11-26

• Corrected formatting for errors on the FieldWidgets object (i.e. from invariants). This closes http://code.google.com/p/dexterity/issues/detail?id=238 [davisagli]

0.5.6 - 2011-06-30

• Make sure group errors get styled like field errors. [davisagli]

• Change inline validation to match archetypes behavior - add a warning class and omit the error message. [elro]

0.5.1 - 2010-11-02

• Make sure form.extractData() does not raise an AttributeError if the method is called before the form is available (first page load). [timo]

• This package now uses the plone i18n domain. [vincentfretin]

• Added option to override <form action=””>. [miohtama]

• Updated README regarding form action and method. [miohtama]

0.5.0 - 2010-04-20

• Cleaned up templates to match Plone 4 conventions. [optilude]

• Made templates and inline validation work with standalone forms as supported by plone.z3cform 0.6 and later. [optilude]

• Installed a browser layer IPloneFormLayer with this package’s extension profile. This inherits from z3c.form’s IFormLayer, allowing the default widgets to work. You should always install this package in portal_quickinstaller before using z3c.form forms in Plone. [optilude]

• Made the textlines widget the default for sequence types with text/ascii line value types. The default widget from z3c.form is too confusing. [optilude]

0.4.9 - 2010-01-08

• Remove unused (and broken on Plone 4) lookup of the current user’s WYSIWYG editor preference. The wysiwyg_support template does this for us. [davisagli]

• Use the date/time widgets from collective.z3cform.datetimewidget as the default widget for Date and Datetime fields. [davisagli]

0.4.4 - 2009-05-03

• Made the KSS validator use traversal instead of getMultiAdapter() to find the form. This makes it work on add forms. See http://code.google.com/p/dexterity/issues/detail?id=27 [optilude]

0.4.3 - 2009-04-17

• Added a display template for the WYSIWYG widget. [optilude]

• Make the ?fieldset.current query string variable work. Set it to the id of a fieldset other than default to pre-select a different fieldset, e.g. …/@@formview?fieldset.current=3 [optilude]

• Hide the ‘default’ fieldset if there’s nothing to show there. [optilude]

• Provide ‘portal’ variable in wysiwyg template, as its used by some editors. [davisagli]

0.4.2 - 2008-09-04

• Make the WYSIWYG widget work also for non-Acquisition wrapped content.

0.4.1 - 2008-08-21

• Removed maximum version dependency on zope.component. This should be left to indexes, known good sets or explicit version requirements in buildouts. If you work with zope.component >= 3.5 you will also need five.lsm >= 0.4. [hannosch]

• Make use of new plone.z3cform support for looking up the layout template by adapter. This means that forms now no longer need to depend on plone.app.z3cform unless they want to use Plone-specific widgets.

0.4.0 - 2008-07-31

• Add inline validation support with KSS

• Require zope.component <= 3.4.0 to prevent compatibility issues with five.localsitemanager, of which a buggy version (0.3) is pinned by plone.recipe.plone 3.1.4. Upgrade to this version if you’re seeing:

  ...
  Module five.localsitemanager.registry, line 176, in registeredUtilities
  ValueError: too many values to unpack

0.3.2 - 2008-07-25

• Fixed a bug in macros.pt where ‘has_groups’ and ‘show_default_label’ for fieldsets were set in the ‘form’ macro, rendering the ‘field’ macro unusable by itself.

0.3.1 - 2008-07-24

• Fixed a bug where we would use the form macros defined in plone.z3cform instead of our own.

0.3 - 2008-07-24

• Create this package from Plone-specific bits that have been factored out of plone.z3cform.
