Problem with Web Folder
by Robert Jean 20 Jun '03

20 Jun '03

Hello, I have set up a Web folder that should let me drag & drop files from my local hard drive to Zope. I am wondering why some files cannot be copied (most work OK). I get the following error: "An error occurred copying some or all of the selected files" Here is the relevant content in Z2.log: <IP> "HEAD <file> HTTP/1.1" 404 1635 "" "Microsoft Data Access Internet Publishing Provider DAV" <IP> "PUT <file> HTTP/1.1" 500 893 "" "Microsoft Data Access Internet Publishing Provider DAV" The error can be reproduced. Both the client and Zope run on XP Professional. Any idea? Robert __________________________________ Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95 per month! http://sbc.yahoo.com

How can I know all the functions that are called by Zope?
by Igor Leturia 20 Jun '03

20 Jun '03

Hi all! I am trying to make a new Zope product, based on LocalFS, so I am trying to change the source code of LocalFS. But in my product, I need to know who is the authenticated user when someone tries to read a file in the local filesystem by writing its URL. The problem is that if I ask UserManager in any function in the source of LocalFS, it always tells me that it is no one. I think I read somewhere, sometime, that the authenticated user can't be read until the end of traversal. So the changes that I have to make in the source code, have to be made somewhere where the traversal has already finished. I've tried in all the functions of the LocalFS product that are called when someone types the URL of a file in the local filesystem, with no luck. So I have two questions: - Does anybody know all the functions that are called in the Zope sources when someone writes the URL of a file in the local filesystem? - Or else, how can I know all the functions that are called, without having to put traces in all the functions in all the Zope source? Thanks in advance, Igor Leturia

can't use new mime type (content_type)
by Rob Boyd 20 Jun '03

20 Jun '03

Hello, I'm having problems with uploaded files not getting their content_type set to their correct mime type. Specifically, .jar and .jnlp files. I added entries to mimetypes.py for them (application/x-jar and application/x-java-jnlp-file) in mimetypes.types_map. I can now change the content_type property of an existing File object to these new types. However, when uploading a file, OFS.Image first correctly gets the content_type when init() calls get_content_type, but then manage_upload resets it to application/octet-stream. During this second round of get_content_type, it finds a content_type of application/octet-stream in the file's headers. Where does this come from? Not the file itself, but the File object? Can anyone shed light on this? Rob __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com

repository with revisions and verson control
by Adam Szpakowski 20 Jun '03

20 Jun '03

Hi, I'm working on project where the implementation of some kind of repository for various types of documents is necessary. The main features to implement for this repository are: - version control: - history - reviewing - undoing changes - rolling back to any revision - immediate (read only) acces to every revision - files locking Each change made to a single document should be writen as a single revision for this object only (CVS like bechaviour) and where rollbacks and locking must be possible for each, single object where is possible. The repository will work through independent interface created in project and not through ZMI. I'm relatively new in Zope and Python. I understood the general concept of ZODB and it's long transactions (which seems to be a base for repository like projects). I've checked OFSP and it's Version support... nice idea but unfortunately I'll need to create a private sesion for each accesed document... it does't looks like solution rather like workaround. Also the project seems a bit abandoned (vide http://dev.zope.org/Wikis/DevSite/Projects/ZopeVersionControl/CurrentStatus) The concept of my project is closer to CVS like system than to one presented in OFSP. I'm strongly determined to implementy this in clean Zope/ZODB. I don't want to loose the benefits of object database (i'll loose it in CVS solutions) because in future the features like ZOE and e.g. DirectoryStorage will be very handy for me. Is there a way to implement such thing in easier way than writing the support for using ZODB transtactions in project from scratch?

Re: [Zope] Using win32com in Zope
by Ashley Lloyd 20 Jun '03

20 Jun '03

Thanks very much to Alexis Roda for this one. Problem solved. For anyone else who gets the same problem, it seemed to be with the installation (or lack of it) of win32com for Zope. The solution I used was based on: http://effbot.org/zone/python-register.htm Although I didn't follow those instructions exactly, it did give me the registry keys to change, then re-install win32com, making it install for the Zope python, rather than the stand-alone Python. Thanks again to Alexis From: "Ashley Lloyd" <ashleylloyd(a)hotmail.com> To: zope(a)zope.org Subject: [Zope] Using win32com in Zope Date: Wed, 18 Jun 2003 11:55:37 +0100 I have been trying to write to Excel from Zope, using win32com.
