How does one default to current date and time for content publishing?

Question

In this link, http://plone.org/documentation/how-to/set-default-datetimefield-current-date-time it describes how to do this with new Schema attributes. I could update all umpteen content types in our system use this method, but I would prefer something a bit less work intensive, since if I have to change umpteen content types it will be all too easy to make a mistake.

Answer 1

I could just make 'published' be the default work flow state. That should address the issue.

Answer 2

maybe a js soln? have an onload event that looks for datetime widgets by id (or one of those common attributes) and then reset the time based on the browser time. You can filter new vs edit based on whether or not a non-prefilled required attribute has been filled yet (i.e. Title)

Answer 3

You could use archetypes.schemaextender to modify those types with an adapter:

in your configure.zcml

<adapter
    factory=".adapters.DefaultDateModifier"
    name="my-package-defaultdate"
    />

in the adapters.py

class DefaultDateModifier(object):
    """DefaultDateModifier adapter
    """
    # XXX optionally adapt your content items iface here
    adapts(ATCTMixin)
    implements(ISchemaModifier)

    def fiddle(self, schema):
        # TODO switch out the default_method here...
        pass

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