Re: [Zope] ZCatalog : Searching Multiple Indexes : Returning One Result
If I understand correctly, this seems like searching for multiple values in
one index. What I'm looking to do is search for one value in multiple
indexes... and get back one result even if there are True hits in more than
one index.

Re: [Zope] getting post data from a webcam
Can you use ftp or webdav, that may be easier, this would take care of
mimetypes without having to move to a lower level. It depends on the
capabilities of your camera but not knowing the model there is limited help.
I had an Axis camera, that ran embedded linux and had a built in python web
server (boa) which I used to get an image from the camera every 5 seconds
replacing the previous image for viewing from our WEB site. And, I had to
put the image directly on the file system and use the Local File System
product for Zope to access it because it was always downloaded under the same
file name and putting it in Zope directly quickly filled up the hard drive
because of the undo option, a learning experience.
It's been so long ago I don't remeber all of the details.

Just a thought... could your front-end (apache?) be stripping out the image
due to attachment size restrictions or some other restriction?

How about the API that BTreeFolder2 provides? Look for generateId(). In my experience it works quite well. It just counts integers up, but resolves conflicts.

If the file is posted as attachment (similar to file upload) it should
appear in the relevant form element as file. You can just use the method
.read() on it to get the data (or feed it into factory of image/file)
Unfortunately it is now showing up in REQUEST.form, it is not a POST like
what
you get with a file upload from a form. Zope is showing that the correct
size
of data was sent to that page.
For this to work the data needs to be sent as
enctype="multipart/form-data" (hopefully the cam does this).
It was not sent with that kind of encoding at least not in any way I can
tell.
It was a webcam and all I could give it was a url to POST the data to and
it
did not submit it like a regular form.
Maybe you send all variables of the request to figure out.

Tino
You need to provide more details... try dumping the contents of REQUEST and
