Wouldn't something like the following create functioality very similar to
that scrteenshot:
class ICriterion(interface.Interface):
"""Search criteria"""
index = schema.Choice(title=u"Index",
values = [u"Last Name", u"First Name"])
constraint = schema.Choice(title=u"Constraint",
values = [u"Contains", u"Doesn't contains"])
value = schema.TextLine(title=u"Value")
class ISearchForm(interface.Interface):
"""Form with a list of subforms"""
match_all = schema.Bool(title=u"Match All of the following",
default=True)
match_any = schema.Bool(title=u"Match Any of the following",
default=False)
criteria = zope.schema.List(
title = u"My list field",
value_type = zope.schema.Object(
title=u'my object widget',
schema=ICriterion),
)
class SearchForm(form.Form):
fields = field.Fields(ISearchForm)
...
i.e. my understanding is that schema.List can render a list of subforms for
its values along with Add and Remove buttons, everything magically
working... I have to admit that I never tried that myself though.
