[Zope3-Users] z3c.selectWidget terms without vocabulary

2008-09-30 Thread kevin gill 
I want to create a select widget based on a field which does not have a
vocabulary. The possible values are determined based on the context or the
view.

How do I configure the z3c SelectWidget to pick up the terms from a set of
terms I provide, rather than looking to the field.

I see from the code that it looks up a registered adapter, but I don't
understand how to control this on a view instance basis.

Thanks

Kevin

OK, I have it working now. Here is what I did...

1.  Subclass the schema type to create a specific class for my field, e.g.

class LocalChoice(zope.schema.Choice):
   Marks this field uniquely

2.  Make a new class based on z3c.form.terms.ChoiceTerms, and register it
for the view and the schema field:

zope.component.adapts(
  zope.interface.Interface,
  z3c.form.interface.IFormLayer,
  ViewClass,
  LocalChoice,
  z3c.form.interfaces.IWidget)

3.  Put in the zcml

adapter ...

And it is picked up fine.

Thanks
