Re: [Zope] PYTHON: Searching for an object inside a folder

16 Oct 2002

      Hi Vitor,

this is a faq ;)

Look for documentation on ZopeFind() and ZopeFindAndApply()
(The Zope source is last resort, but also google, Zope.org
and the parameters on Zopes managements "Find" page)

Or see the following example:

Hi!
I need to check, inside a Python script, if an object with a
particular ID exists inside a folder.
    Right now I'm using the following code:
# this is the folder I want to search
    myFolder = container.REQUEST.PARENTS[0].img_folder
# search the folder for an object with ID <object_id>
    obj = getattr(myFolder, object_id, None)
    if obj is not None:
        # there is no such object
    else:
        # there is an object with that id
Is there a more efficient way to perform this operation?
kind regards,
