Hello Andrew, Did you specify enctype="multipart/form-data" in your FORM tag? Here is an example from a ZClass I use: <FORM action="PDFFileClass_add" enctype="multipart/form-data" method="post"> ... <INPUT type=file name="file" size="30"> ... </FORM> HTH.

Updated GUF prerelease
by Stuart 'Zen' Bishop 02 Apr '00

02 Apr '00

My patch release of GUF turned into a fairly hefty rewrite. Version 1-2-0 is now available on the web site, and I'll be announcing it to the main mailing lists and the web site in a few days time unless there are glaring problems. I'd be interested in hearing if this release works with the Chameleon product - I had a patch to incorporate, but it appeared to be causing other problems and probably not needed anymore. Authors of other user sources may want to go over the _cookie_validate method - I now have authentication via higher acl_users folders working, while still keeping the nice cookie login screens (and without that dodgy 'crawl up the tree' code which didn't really work anyway). -- ___ // Zen (alias Stuart Bishop) Work: zen(a)cs.rmit.edu.au // E N Senior Systems Alchemist Play: zen(a)shangri-la.dropbear.id.au //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen

Hello! I'm trying to create a product to store HTML-file with comment and title fields. In product i have file with id "text". Add form looks: ... <tr><th>File</th> <td><input type="file" name="file"></td> </tr> ... Add method: ... <dtml-with "manage_clone(ArticleClass,REQUEST['id'],REQUEST)"> <dtml-call "text.manage_upload(REQUEST['file'])"> ... After adding instance of product in folder i have path string in file text instead of downloaded html-source. what i'm doing wrong? don't tell me to use python external method in product. i want to do it in terms of dtml. thanx in advance. Best regards, Andrew http://exper.ural.ru/ mailto:exper@inbox.ru

I don't know Perl at all so I'm probably not going to investigate this, unless the algorithm is pretty simple. Also the morphological dictionary looks like it can get big, I'd like to use a more advanced data structure than just a flat file dictionary; the splitter is used very often, and constantly refering to a flat file would be horrible. I was probably going to use their dictionary to start with. > b) What algorithm do you use in your searching of text ? Is it just a > simple frequency tally ? I'm not sure what a simple frequency tally is. A text index is a mapping from a word id to a sequence of (documentid, score) tuples. o The word id (which is an integer) is mapped to a word by the Lexicon, o the document_id (which is also an integer) is mapped to a 'document' (and Zope object really) by the Catalog. o The score is the number of times the word that maps to the word id was found in the document that maps to the document id. Text indexes do not make any assumption about what a 'word' is, or how it came to be a word. All language specific information, such as how to split a document in a certain language into words, is handled by the Lexicon. The splitting of a 'document' into words is done by the Splitter object provided by the Lexicon. The Splitter object is what would need to implement the morphological analysis algorithm for whatever language you are going for. In the case of english, this is very simple and involves splitting a document up at whitespaces. The algorithm for Chinese or Japanese is much harder, as you're aware. -Michel

socket newbie question
by Toby Dickenson 01 Apr '00

01 Apr '00

In select_trigger.py, the non-posix version of the trigger class binds a socket to a port on the address 127.9.9.9. Can anyone explain the significance of using this address, rather than 127.0.0.1 ? Thanks, Toby Dickenson tdickenson(a)geminidataloggers.com

Hey, ZEO will allow several Zope installations to work as one distributed Zope system. In other words ,this accomplishes what you describe invisibly.

Zope Inter-Object Communication Protocol

Zopists, Is there currently any effort to develop a way for a Zope object from one ZODB to communicate with another object from another ZODB? JNI like stuff, or other what-cha-ma-call-its... All my best, -- Jason Spisak 444(a)hiretechs.com

Security gap in "Manage users" & "Manage permissions" permissions (IMHO)
by Lalo Martins 31 Mar '00

31 Mar '00

One thing I like about proxy roles is that you can't give a proxy role for a role you don't have. Equally, IMHO when you have the "Change permissions" permission you shouldn't be able to grant permissions you don't have. And if we want completeness, when you have "Manage users" you shouldn't be able to give roles you don't have _except_ if you're Manager (because otherwise it would be impossible to create new roles...) Is there a flaw in my reasoning? (What I'd like to do in practice is create an "Admin" role for a subsite and grant "Manage users" to this role, so that they can create new users and grant the "Admin" and "Narrador" roles for other users. But as it currently stands, if I give them "Manage users" they can grant "Manager" to themselves and do pretty much anything.)
