Interface marker field for Archetypes

Project Description


This packages contains a single Archetypes field that can manage one or more marker interface on an object.

It is most often used with archetypes.schemaextender to add a field to a type which controls new optional behaviour.


This example adds a new item to the settings fieldset for an object which controls an ICategory marker interface:

class FolderExtender(object):
    """Add a new 'category' field to all Archetypes based folder types.

    fields = [
                schemata = "settings",
                interfaces = (ICategory,),
                widget = BooleanWidget(
                    title = _(u"label_category",
                                default=u"Is this folder a category."),
                    description = _(u"help_category",
                                default=u"This should briefly explain what "
                                        u"categories are used for."),

    def __init__(self, context):
        self.context = context

    def getFields(self):
        return self.fields
