hi, i tried entering the following (using 'Add Z MySQL Database Connection'): user/password user/paasword@myhost but none of them worked and return a 'bad request': <Traceback> Traceback (innermost last): File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope-2.0.1-src/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: addConnection) File /usr/local/Zope-2.0.1-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: addConnection) File /usr/local/Zope-2.0.1-src/lib/python/Products/ZMySQLDA/DA.py, line 123, in addConnection (Object: ElementWithAttributes) File /usr/local/Zope-2.0.1-src/lib/python/Shared/DC/ZRDB/Connection.py, line 124, in __init__ (Object: RoleManager) File /usr/local/Zope-2.0.1-src/lib/python/Shared/DC/ZRDB/Connection.py, line 153, in edit (Object: RoleManager) File /usr/local/Zope-2.0.1-src/lib/python/Shared/DC/ZRDB/Connection.py, line 197, in connect (Object: RoleManager) File /usr/local/Zope-2.0.1-src/lib/python/Products/ZMySQLDA/db.py, line 155, in __init__ BadRequest: (see above) </Traceback> What Am I doing wrong?

Zope 2.0.1 does not come with the localization code, the next release (and the CVS, and Chris mentioned) will. You are doing everything correctly, you just need to be using the new Catalog. If you're daring, you can check out a CVS copy and replace 2.0.1's lib/python/Products/ZCatalog with the checkout. Note that you will also need to replace the contents of lib/python/SearchIndex. The new catalog will automatically sniff your LC_ALL env variable and call the posix function to set the locale. Now, whether or not this will do anything is yet to be tested. Perhaps you can help us with that. According to our analysis, it should work for you, but we are not in a position to put it to a real world test. -Michel

ZCatalog and searching for german Umlaute
by Michael Gutmann 25 Oct '99

25 Oct '99

Hi folks, I've got a nasty problem with ZCatalog, that I cannot locate (localize :-). I have DTML-Documents with the word "König" in a property (title) and in the body. If I enter "König" in a formfield named "suchwort" and search with Catalog.searchResults({'title':suchwort}) or Catalog.searchResults({'raw':suchwort}) the document, which is indexed and found using other words, is not found. Even if I search explicitly after "König" like in Catalog.searchResults({'title':'König'}) or Catalog.searchResults({'raw':'König'}) the document won't be found. This is Zope 2.0.1 with ZServer directly accessed (not via Apache) and LC_ALL=de is set (and exported ;-) on an UltraSPARC with SunOS 5.7. Anybody any idea in this specific case? I must admit, that this is a very serious problem for our site and makes it hard for me to convince my users of the excellence of Zope. Well, I am convinced, though. But tell them that ...

Q: Iterating through an arbitrary number of SUBMIT form REQUEST object files/attributes?
by Samu Mielonen 25 Oct '99

25 Oct '99

I've mananed to solve every single problem regarding to saving images, replacing images, referencing image sizes, etc,. Thanks to all the kind people on the list fo comments. However, I'm still unsure how to handle the form data send via post method by the browser. Consider an arbitrary submit-form that contains different variable types (text, numbers, boolean) and various file types (images, video, etc.) via file-upload buttons. Is there a way to handle a REQUEST object (from the above arbitrary submit form) in such a manner that that it: 1) Automatically reads all variable names, types and values (e.g. <input type="text" name="name1:text"> with value "John Smith" is turned into a property name1 with value 'John Smith' for the object to be handled) 2) Automatically reads through all the included files (submitted through multipart/form-data), detects their type (if possible) and saves the inside the object in question as sub-objects. (e.g. parrot.jpg is understood to be a file of type Image and saved as an image object with the id "parrot.jpg" or just "parrot") Is this too much of an Herculean undertaking or is it something done easily? I'm most interested in iterating through all of the encoded files of a form submitted REQUEST object and saving each of them with a proper id and type (image, etc) inside a folder (object). Best regards, Samu Mielonen PS I think I'm over the tipping point at which I'm starting to appreciate the power of Zope, although learning is still very slow for me and I mungle with syntax all the time :) -- "Our reflections on the order of society, as well as nature, are still dominated by the Newtonian image of massive power, exerted by sovereign agency through the operation of central force..." -Stephen Toulmin, "Cosmopolis"

RE: [Zope] Could someone translate the debugging information?
by Michel Pelletier 25 Oct '99

25 Oct '99

This can be avoided by changing the following line in your Zope.cgi file: PCGI_PUBLISHER=/home/michel/dev/Portal/pcgi/pcgi_publisher.py to an empty dummy file. This way, pcgi-wrapper will not try to file up Zope The Old Way. Whether or not this was the original problem is unkown. If VanL say the error in the browser, then it was, if in the terminal, then it's a permission problem. -Michel > -----Original Message----- > From: Jeff Rush [mailto:jrush@timecastle.net] > Sent: Sunday, October 24, 1999 10:22 PM > To: Michel Pelletier; VanL; zope(a)zope.org > Subject: RE: [Zope] Could someone translate the debugging information? > > > Actually I've seen the error about not having access to Z2.pid > occur for reasons other than file permissions per se.

Re: [Zope] Creating Products in Python

Your wish is granted -- I've updated the source to the old Poll Product that Amos created to demonstrate how to write Zope Products in Python. I took what I've learned from my Equation Tile product and moved it into the Poll product this morning. It now supports Zope 2.0.1, being subclassed via ZClasses, is CatalogAware and shows off a few tricks such as how to add those TALLER/SHORTER/ WIDER/NARROWER buttons for resizing text input boxes. It also shows how to have a method return an HTML fragment when called for embedding it into another page, or a standalone HTML source if called as it's own web page. I didn't have time to update the Tutorial document that comes with it. Perhaps later, or someone else is welcome to tackle it. You can find it at the bottom of my web page at: http://starship.python.net/crew/jrush/Zope/ I tried for some time to upload it to www.zope.org this morning, but the site was dog-slow and in read-only mode! Any attempt to add anything simply spun the indicator in Netscape, for over an hour for a 47K upload. Downloads worked but typically took 3-5 mins per page. Sheez! I hope they get the new servers soon. >What's the best way of forcing a product to reload? Deleting it, adding it >again and restarting Zope is becoming somewhat tedious. That's the way you do it -- yes it is tedious but considering how products hook into Zope, I doubt the Python reload technique will ever work for Products. -Jeff Rush

If you use Frames (ick), it might be possible to have more than one tree. Unfortunately, you couldn't depend on the default cookies to hold the independant tree states correctly.
