megrok.z3cform.composed 0.1

Context

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

>>> class MyContent(object):
...    pass

Declaration

>>> class Form(ComposedForm):
...   grok.context(MyContent)

Registration

>>> grok_component('composed', Form)
True

Query

>>> content = MyContent()
>>> request = TestRequest()

>>> composed = getMultiAdapter((content, request), name="form")
>>> composed
<megrok.z3cform.composed.tests.Form object at ...>

>>> composed.subforms
[]

>>> composed.updateForm()
>>> composed.subforms
[]

Declaration

>>> 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)

Registration

>>> grok_component('one', SubFormOne)
True

>>> grok_component('one', SubFormTwo)
True

Query

>>> 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 ...>
