megrok.z3cform.composed is a package dedicated to define and register composed forms. Composed forms are forms built from a collection of sub forms.

megrok.z3cform.composed is based on z3c.form and megrok.z3cform.base.

Getting started

We import the needed dependencies:

>>> import grokcore.view as grok
>>> import megrok.z3cform.composed
>>> from megrok.z3cform.composed import ComposedForm, SubForm

We import the components utilities:

>>> from zope.component import getMultiAdapter
>>> from zope.publisher.browser import TestRequest

Defining a composed form


A form needs a context. Let's create a simple model for test purposes:

>>> class MyContent(object):

System Message: ERROR/3 (<string>, line 37)

Inconsistent literal block quoting.

... pass

>>> class Form(ComposedForm):
...   grok.context(MyContent)
>>> grok_component('composed', Form)
>>> content = MyContent()
>>> request = TestRequest()
>>> composed = getMultiAdapter((content, request), name="form")
>>> composed
<megrok.z3cform.composed.tests.Form object at ...>
>>> composed.subforms
>>> composed.updateForm()
>>> composed.subforms

Defining sub forms

>>> class SubFormOne(SubForm):
...     grok.context(MyContent)
...     megrok.z3cform.composed.order(2)
...     megrok.z3cform.composed.view(Form)
>>> class SubFormTwo(SubForm):
...     grok.context(MyContent)
...     megrok.z3cform.composed.order(1)
...     megrok.z3cform.composed.view(Form)
>>> grok_component('one', SubFormOne)
>>> grok_component('one', SubFormTwo)
>>> composed.subforms
>>> composed.updateForm()
>>> composed.subforms
[<megrok.z3cform.composed.tests.SubFormTwo object at ...>, <megrok.z3cform.composed.tests.SubFormOne object at ...>]
>>> for sub in composed.subforms:
...   print sub.prefix, sub.parentForm
subformtwo <megrok.z3cform.composed.tests.Form object at ...>
subformone <megrok.z3cform.composed.tests.Form object at ...>
