megrok.z3cform.base Description

megrok.z3cform.base is a not-so-thick layer above z3c.form. It provides a Grok way to register your forms and your widgets. In addition, the package has a collection of base forms, useable out-of-the box with grokcore.layout (or the old megrok.layout).The customization of the forms is also eased by the use of megrok.pagetemplate, allowing you to override a template easily.Form registrationModelsWe set up some models to serve as a form context:>>> import grokcore.component as grok>>> from zope import interface, schema>>> class IMammoth(interface.Interface):... name = schema.TextLine(title=u"Name")... age = schema.Int(title=u"Age")>>> class Mammoth(grok.Context):... grok.implements(IMammoth)... name = schema.fieldproperty.FieldProperty(IMammoth)... age = schema.fieldproperty.FieldProperty(IMammoth)We declare the Form. It's very similar to a grok.View:>>> import megrok.z3cform.base as z3cform>>> class TestForm(z3cform.Form):... grok.context(Mammoth)Grokking and queryingWe let Grok register the component:>>> grok.testing.grok_component('form', TestForm)TrueNow, we can query it normally:>>> from zope.publisher.browser import TestRequest>>> request = TestRequest()>>> manfred = Mammoth()>>> from zope.component import getMultiAdapter>>> myform = getMultiAdapter((manfred, request), name="testform")>>> myform< TestForm object at ... >>>> print myform()< form action="http://127.0.0.1" method="post" enctype="multipart/form-data" class="form-testform" >...Layout integrationmegrok.z3cform.base is integrated, out-of-the-box with grokcore.layout, providing base classes to ease the layout integration in your project.Let's have a quick overview. We create a layout:>>> import grokcore.layout>>> class MyLayout(grokcore.layout.Layout):... grok.context(IMammoth)... def render(self):... return 'The layout content is: %s' % self.view.content()We declare a Page Form. A Page Form is a form that will show up inside a layout:>>> class PageForm(z3cform.PageForm):... grok.context(Mammoth)We register the components with Grok:>>> grok.testing.grok_component('page', PageForm)True>>> grok.testing.grok_component('layout', MyLayout)TrueNow, while rendering the form, we have it embedded in the Layout:>>> pageform = getMultiAdapter((manfred, request), name="pageform")>>> print pageform()The layout content is: < form action="http://127.0.0.1" method="post" enctype="multipart/form-data" class="form-pageform" >...Product's homepage
