[Zope] Upload files, set properties, search props

[John Toews]

Thank you, pointing out I could do this without a Zclass is going to
save me time... The one thing I don't understand right now. The code
below adds a property to the containing folder, not the object I just
uploaded. How do I obtain the id so I can deal with that? (objects is
the name of my folder, it is a level under the script itself)

<dtml-call expr=3D"objects.manage_addFile(id=3D'', file=3Dfile,
title=3D'test')">
<dtml-call expr=3D"objects.manage_addProperty('keywords', keywords,
'text')">

I think the second one should be something like
objects.UPLOADED_FILE_ID.manage_addProperty...

Thanks!

the details vary depending on whether you want 1 property per keyword,
or 1 property for all keywords. but the basics can be gleaned from
the online zope book:
http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/ScriptingZop
e.stx

read the section on "The Zope API". There are examples of adding and
changing properties.

e.g. in the script that's the target of your form, do something like
this
to add a single property:

request =3D context.REQUEST
my_folder.manage_addProperty('keywords', request.get('keywords'),
'text')

no problem, just give youtr catalog a KeywordIndex with the name of your
property.

not necessary, the above will work.

the only advantage of a custom Product (whether zclass or
filesystem-based
product) is that it can be made to support automatic cataloging
so you don't have to periodically update the catalog.
