Hi. As Zope 2.7 looks like could-be-out-soon. I'd like to ask if there is room for including the post-traverse patch in Zope 2.8. I'm currently maintaining it as a patch on a branch for Zope 2.7, but would like to see it back in the mainstream.
Short description of it:
- Sometimes you want to run code before the published object
as in
the before_traverse hooks. But there you miss to variables: The object
to be published and security context.
- During traversal you can register yourself to be called
after those
two variables have been determined. This results in a chain of methods
to be callen.
- When the methods are callen, they get the necessary
contexts and
can return None (everything as usual) or return something else, that
should be used for publication instead of the object that was found by
traversal. (Note: I intended it that the
REQUEST['PUBLISHED']
remains the one found by traversal.) This also discontinues the chain
of post traversal calls.
If this is feature could be a candidate for 2.8, i'll write a more
in-depth proposal on it, and can provide the necessary code.
Cheers,
Christian
