We have a requirement for a dexterity content type to have exclude from navigation behaviour but for the exclude_from_nav
field's default value to be True
. In the behaviour plone.app.dexterity.behaviors.exclfromnav.IExcludeFromNavigation
it defaults to False
.
Obviously I could create my own behaviour that copies IExcludeFromNavigation
except for the default value but I was wondering if there was a way to do this based on reusing IExcludeFromNavigation
. We have other content types that use IExcludeFromNavigation
where we do want it to default to False
.
We're using Plone 4.1rc3 and Dexterity 1.0
See http://plone.org/products/dexterity/documentation/manual/developer-manual/advanced/defaults and http://pypi.python.org/pypi/plone.directives.form#value-adapters, but basically:
Cheers, Martin
I have this working using a
plone.directives.form
decorator.I've added this to one of my behaviour modules.
I also have the following in configure.zcml
Thanks to Martin for the large clue although his answer didn't quite solve my problem. This feels like a bit of a hack to me - a more elegant solution would be nice.
