Hiding a specific object of a catalog results

Question

There is a way to hide a specific object of my catalog results? I have a configuration file that I don't want to show. I'm filtering by id, but it seems so ugly.

from Products.CMFCore.utils import getToolByName
def search(context):
    catalog = getToolByName(context, 'portal_catalog')
    items = catalog()
    for item in items:
        if item.id != "config_file":
            'do something'

Answer 1

If you are already hiding the object from the navigation tree, you can filter on the same property by testing for exclude_from_nav:

items = catalog()
for item in items:
    if item.exclude_from_nav:
        continue

    # do something with all objects *not* excluded from navigation.

It is harder to filter out things that don't match a criteria. Using a test on the brain object like the above is a perfectly fine way to remove a small subset from your result set.

If you need handle a larger percentage of 'exceptions' you'll need to rethink your architecture, perhaps.
