[Zope3-Users] AW: AW: z3c.form and subforms in an AddForm?

Roger,

> You missed in the AddressAddForm ``self.widgets.ignoreContext = True``

I see that I missed that statement, it was late on a sleepless night, but I
couldn't get this out of my head.  In any case, I've changed my code to
match the example you gave in the repository.  I also have the templates
defined in the view instead of through zcml as you have in the tests.

browser/restaurant.py

class RestaurantAddForm(form.EditForm):
    """Add form"""
    
    fields = field.Fields(IRestaurant).select('name', 'description')
    template = viewpagetemplatefile.ViewPageTemplateFile('restaurant.pt')
    prefix = u'restaurant'
    
    def updateWidgets(self):
        self.widgets = component.getMultiAdapter((
            self, self.request, self.getContent()), IWidgets)
        self.widgets.ignoreContext = True
        self.widgets.update()
        
        
    def update(self):
        self.address = AddressAddForm(None, self.request)
        self.address.update()
        super(RestaurantAddForm, self).update()

browser/address.py

class AddressAddForm(form.EditForm):
    fields = field.Fields(IAddress)
    template = viewpagetemplatefile.ViewPageTemplateFile('address.pt')
    prefix = u'address'
    
    def updateWidgets(self):
        self.widgets = component.getMultiAdapter((
            self, self.request, self.getContent()), IWidgets)
        self.widgets.ingoreContext = True
        self.widgets.update()

browser/configure.zcml

  <z3c:pagelet
    name="addRestaurant.html"
    for="zope.app.container.interfaces.IContainer"
    class=".restaurant.RestaurantAddForm"
    layer="metrod.app.layer.IMetroDBrowserLayer"
    permission="zope.Public" />

I believe those matches your example exactly but I still get the adaption
error when the form should be displayed.

Traceback (most recent call last):

    result = publication.callObject(request, obj)

    super(Form, self).update()

    value = zope.component.getMultiAdapter(
  Module z3c.form.datamanager, line 48, in get
    context = self.field.interface(context)
TypeError: ('Could not adapt', None, <InterfaceClass
metrod.restaurant.interfaces.IAddress>)

Am I forgetting some configuration on my forms?  I have not configured
anything for AddressAddForm could that be the issue?

Not sure I'm understanding this, your example used EditForm without any
thought on superclasses.

Again thanks for all your time and effort, I really appreciate this.

PS. Would there be a chance you could include the car/owner example in the
z3c.formdemo package?
