Introduction
=============
This package enables the use of z3c forms in grok.View style inside a plone environment.
Note that you have two wrappers and a basic form class:
- *FormWrapper* to use the basic ``z3c.form`` template
- *PloneFormWrapper* is a basic z3c.form wrapper with some plone integration (fieldsets & kss) (from ``plone.app.z3cform``)
- *PloneForm* is a basic z3c.form with some plone integration (fieldsets & groups) (from plone.app.z3cform)
- A *TestCase* to test your code with z3cform.grok with either using directly itself or by sublassing it

Basic Usage
=============
Declare a form in 'foo.py' module
::
>>> import plone.z3cform.fieldsets.extensible.ExtensibleForm$
>>> import z3c.form.form.Form
>>> class Myform(plone.z3cform.fieldsets.extensible.ExtensibleForm, z3c.form.form.Form):
... """A z3c.form"""
... ingoreContext = True or False # override me
Note that ``collective.z3cform.grok.grok.PloneForm`` is a shortcut to the previous declaration, see implementation.
Then a Wrapper
::
>>> from collective.z3cform.grok.grok import PloneFormWrapper
>>> class myview(PloneFormWrapper):
... form = Myform
Write a basic template, in foo_templates/myview.py, for example:
::
<tal metal:use-macro="context/main_template/macros/master">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
xmlns:i18n="http://xml.zope.org/namespaces/i18n"
i18n:domain="nmd.sugar.forms"
xml:lang="en" lang="en"
tal:define="lang language"
tal:attributes="lang lang; xml:lang lang">
<body>
<metal:main fill-slot="body">
<tal:block tal:content="structure python:view.render_form()"></tal:block>
</metal:main>
</body>
</html>
</tal>
Et voila, you can access your form @
- http://url/@@myview
Basic grok testing in a third party package
=============================================
Import the basic testcase
::
>>> from collective.z3cform.grok.tests.test_doctests import DocTestCase as dt
>>> from collective.z3cform.grok.tests.test_doctests import collective_z3cform_grok_setUp
>>> from collective.z3cform.grok.tests.test_doctests import collective_z3cform_grok_tearDown
Compose a testcase with one of your favourite testcases
::
>>> class DocTestCase(MyFunctionalTestCase, dt):
... def setUp_hook(self, *args, **kwargs):
... MyFunctionalTestCase.setUp(self)
... def tearDown_hook(self, *args, **kwargs):
... MyFunctionalTestCase.tearDown(self)
... def afterSetUp(self):
... """."""
... MyFunctionalTestCase.afterSetUp(self)
...
Make a doc_suite soap assembling the whole
::
>>> def test_doctests_suite(directory=None, globs=None, suite=None, testklass=None):
... if not testklass: testklass=DocTestCase
... if not directory:
... directory, _f = os.path.split(os.path.abspath(__file__))
... elif os.path.isfile(directory):
... directory = os.path.dirname(directory)
... files = [os.path.join(directory, f) for f in os.listdir(directory)
... if f.endswith('.txt')]
... if not globs:
... globs={}
... g = globals()
... for key in g:
... globs.setdefault(key, g[key])
... directory = directory
...
... if not suite:
... suite = unittest.TestSuite()
... if files:
... options = doctest.REPORT_ONLY_FIRST_FAILURE |\
... doctest.NORMALIZE_WHITESPACE | doctest.ELLIPSIS
... for test in files:
... ft = ztc.ZopeDocFileSuite(
... test,
... test_class=testklass,
... optionflags=options,
... globs=globs,
... setUp=collective_z3cform_grok_setUp,
... tearDown=collective_z3cform_grok_tearDown,
... module_relative = False,
... )
... suite.addTest(ft)
... return suite
>>> def test_suite():
... """."""
... suite = unittest.TestSuite()
... return test_doctests_suite(suite=suite)
Et voila, all files ending with txt in the tests directory will be tested with that magic TestCase.
Using grok.View to display z3c.forms in plone
========================================================
The goal of this package was to make a very minimal integration of z3c.form and plone.
Far from plone.app.directive, my goal was to be light.
Do a simple naming schema
::
<<< import collective;from five import grok
<<< import zope, z3c
<<< class IMyFormSchema(zope.interface.Interface):
... name = zope.schema.Text(title=u"Name", description = u'Name', required=False)
<<< class MyForm(z3c.form.form.Form):
... ignoreContext = True
... fields = z3c.form.field.Fields(IMyFormSchema)
... @z3c.form.button.buttonAndHandler(u'Ok', name='Ok')
... def ok(self, action, *args, **kwargs):
... msg = u'me Grok NameField <> @name == %s' % self.widgets['name'].value
... from Products.statusmessages.interfaces import IStatusMessage
... IStatusMessage(self.request).addStatusMessage(msg, type='info')
The grok.View wrapping form can be looking like that
::
<<< class myview(collective.z3cform.grok.grok.FormWrapper):
... grok.context(zope.interface.Interface)
... form = MyForm
Note that this grok style class support those attributes:
- layer: the Form Layer
- Any grok directive (require, template, context, etc.)
- form: The form class
- Think that you can add some directives also on your form like ignoreContext
- As we know how grok works, telling that we want an Interface as a context says that this form applys everywhere.
- ``ignoreContext`` is used just to drop context mapping.
- All that we have to do now is to instantiate and render our view and our form.
And with grok magic, the view is already registered on our portal
Note that its template will automaticly resolve to ``module_templates/lower_view_name.pt``, and here: ``form_templates/bar.bt``
::
>>> request = make_request()
>>> interface.alsoProvides(request, z3c.form.interfaces.IFormLayer)
>>> interface.alsoProvides(request, zope.annotation.interfaces.IAttributeAnnotatable)
>>> pv = getMultiAdapter((portal, request), name='myview')
>>> pv.template.__grok_location__.endswith('form_templates/myview.pt')
True
>>> print open(pv.template.__grok_location__).read()
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
xmlns:i18n="http://xml.zope.org/namespaces/i18n"
lang="en" xml:lang="en"
metal:use-macro="context/main_template/macros/master">
<body>
<metal:main fill-slot="main">
<tal:main-macro metal:define-macro="main">
<p>my grokky template</p>
<p>The form is:</p>
<tal:block tal:content="structure python:view.render_form()"></tal:block>
</tal:main-macro>
</metal:main>
</body>
</html>
<BLANKLINE>
We need to call the update method to manually trigger the form.update() process
::
>>> pv.compute_widgets()
>>> print '\n'.join([a.rstrip() for a in pv.render_form().split('\n') if a.strip()])
<form action="http://nohost/@@myview" method="post"
enctype="multipart/form-data">
<div class="row">
<div class="field">
<label for="form-widgets-name">
<span>Name</span>
</label>
<div class="formHelp">Name</div>
<div class="widget">
<textarea id="form-widgets-name" name="form.widgets.name"
class="textarea-widget text-field"></textarea>
</div>
</div>
</div>
<div class="action">
<input type="submit" id="form-buttons-Ok"
name="form.buttons.Ok"
class="submit-widget button-field" value="Ok" />
</div>
</form>
>>> pv.__class__
<class 'collective.z3cform.grok.tests.form.myview'>
Verify the authenticity of our grok.View
::
>>> from zope.interface.verify import verifyObject
>>> from grokcore.view.interfaces import IGrokView
>>> pv.request is request
True
>>> verifyObject(IGrokView, pv)
True
We can also test that all is in place through the web and that our view is registered and the ``switch_on`` cruft works. Note that it uses the plone.app.z3cform ``form.pt`` template.
::
>>> browser.open(portal.absolute_url()+"/@@myview")
>>> print '\n'.join([a.rstrip() for a in browser.contents.split('\n') if a.strip()])
<...<p>my grokky template</p>...<p>The form is:</p>
...<p class="discreet"></p>
...<form class="rowlike enableUnloadProtection kssattr-formname-@@myview"...action="http://nohost/plone/@@myview"...
...id="form-widgets-name"...
...id="form-buttons-Ok"...
...</form>...
Testing that the form submission & actions are working
::
>>> browser.handleErrors = False
>>> browser.open(portal.absolute_url()+"/@@myview")
>>> browser.getControl(name='form.widgets.name').value = 'foo'
>>> browser.getControl(name='form.buttons.Ok').click()
>>> browser.url
'http://nohost/plone/@@myview'
>>> 'class="textarea-widget text-field">foo</textarea>' in browser.contents
True
Opening again with our StatusMessage cookie which has been set by previous request
::
>>> '<dd>me Grok NameField <> @name == foo</dd>' in browser.contents
True
collective.z3cform.grok Installation
==============================================
To install collective.z3cform.grok into the global Python environment (or a workingenv),
using a traditional Zope 2 instance, you can do this:
* When you're reading this you have probably already run
``easy_install collective.z3cform.grok``. Find out how to install setuptools
(and EasyInstall) here:
http://peak.telecommunity.com/DevCenter/EasyInstall
* If you are using Zope 2.9 (not 2.10), get `pythonproducts`_ and install it
via::
python setup.py install --home /path/to/instance
into your Zope instance.
* Create a file called ``collective.z3cform.grok-configure.zcml`` in the
``/path/to/instance/etc/package-includes`` directory. The file
should only contain this::
<include package="collective.z3cform.grok" />
.. _pythonproducts: http://plone.org/products/pythonproducts
Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance
recipe to manage your project, you can do this:
* Add ``collective.z3cform.grok`` to the list of eggs to install, e.g.::
[buildout]
...
eggs =
...
collective.z3cform.grok
* Tell the plone.recipe.zope2instance recipe to install a ZCML slug::
[instance]
recipe = plone.recipe.zope2instance
...
zcml =
collective.z3cform.grok
* Re-run buildout, e.g. with::
$ ./bin/buildout
You can skip the ZCML slug if you are going to explicitly include the package
from another package's configure.zcml file.
