I suppose the 'official' solution is the next Zope release, which has a much improved Catalog, including Vocabulary objects so you can specify your stopwords without hacking the source. If you're curious about it, track the CVS. -Michel

SendMail woes . . .
by Jerry.Spicklemire＠IFLYATA.COM 21 Sep '99

Hi Folks, Below is my reply, and the original post from Squishdot. Today another post showed up in the List Search re. problems w/ the MailHost Object. Thanks for looking into this, Jerry S. I'm not using Squishdot yet, but I have had a similar problem with the Zope MailHost Object. I get errors from the SMTP host saying the recipient is missing. Of course I assumed it was the SMTP that was configured wrong, but maybe there's a more basic issue here. Or maybe the documentation is misleading and so folks are having trouble getting things set up correctly. At any rate, you're not alone. I'll send a note to the Zope list, maybe someone there has a clue. Posted by Chris McDonough on Wednesday September 08, @06:38PM from the this-is-good-stuff dept. Wow. WOW! That's all I can say about Squishdot. I do have a problem, though, and would be grateful if anyone else admitted same.. I can't seem to get this thing to do email notifications to replies properly. I see the mail coming in to the mail host, but its got a blank recipient and therefore does not make it in to the (proper) recipient mailbox.

I've installed the XMLDocument-1.0a1 Product and after that when trying to create a zclass object(select ZClass from the available objects combo) in a product folder I get this error: ---------------------------------------- Error Type: TypeError Error Value: unbound Python method must be called with Node 1st argument Traceback (innermost last): File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addZClassForm) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_addZClassForm) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_addZClassForm) (Info: /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/ZClasses/addZClass.dtml) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: manage_addZClassForm) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: _(selected=[], unselected=[], baseclasses=[], id='', title='', meta_type='', all=manage_subclassableClassNames(), )) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: REQUEST) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: _( selected=_.reorder( all, with = baseclasses+ (REQUEST.get('manage_addZClassForm','')==' -> ' and unselected or []), without= (REQUEST.get('manage_addZClassForm','')==' <- ' and selected or []) ), )) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: _(unselected=_.reorder(all, without=selected))) File /usr/local/src/Zope-2.0.0-linux2-x86/lib/python/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: unselected) TypeError: (see above) -------------------------------------------------------------------- I've started from scratch a fresh version of Zope(2.0.1) and installed the xmldocument-1.0a1 after what I was no more enabled to create zclass objects.

manage_clone gives permission error since Zope2
by Florian Mueller 21 Sep '99

21 Sep '99

Hi there! Since we upgraded to Zope 2.0.0b4, I have major troubles with "manage_clone" in a product which worked fine before. Whenever I try using it, I get permission errors, even the superuser cannot use the method that worked fine before. Assuming I did something wrong, I took the Zope Content Manager Guide and typed the Plutonia example in again. It uses "manage_clone" as I do in my product. I ran this example, and hey! It did not work and gave the same weired "ApplicationDefaultPermissions" errors and stuff like that. I tried login as a superuser, and again I got authorization errors. First of all I though the error must have to do with wrong permission settings of my role, but than the superuser should not get an error, right? I also don't understand the new "mapping" permissions in the products since Zope2. Any clarification? Please send any reply directly to me! Thanks, Floyd

MySQLDA connection string?
by Joseph Mann 21 Sep '99

21 Sep '99

Yes I am a newbie to MySQL and Zope 2 ... However I have installed MySQLdb-0.1.0 and applied applied the patch that comes with it to MySQLDA. And I got MySQLdb working in a little python session. So the question is: what is the magic connection string that I have to give to the form when I want to add a "Z MySQL Database Connection". Sorry if I missed some very explicit instructions, but an honest attempt was made to do the homework. Thanks for your indulgences, Joseph Mann

patch: "FullTextIndex" fix for ZCatalog weirdness
by Michael Halle 21 Sep '99

21 Sep '99

The fact that ZCatalog currently does unexpected things with query words that are "stop words" was a show-stopper for my application. While discussion on the mailing list included possible big-picture fixes, I chose a simple quick solution to the problem. I added a new Index type, "FullTextIndex," to augment the existing "TextIndex" and "FieldIndex". Using "FullTextIndex", the stop word dictionary is set to {}, forcing a full text catalog to be built. While noise words will cause inflated indices and spurious searches, at least the results are intuitive. "FullTextIndex" makes sense for titles and keyword fields; it doesn't make sense for long documents. Diffs from Zope-2.0.0 follow. The patch also includes the fix to sort-order posted to this list. Apply with patch -p0 from the top level Zope directory. Remember kids, this isn't an official patch!

Re: [Zope] Clarifying ZCatalog-aware update conditions

Yep. Be aware though that if you are setting properties in your ZClass_add method, you will need to call reindex_object afterwards. >- Deleting an object (but not if you delete the folder which contains the >object (but what if the object IS a folder?)). Hmm... I know that deleting seems to remove the object from an index, but I didn't realize that if you delete the folder that the object does not go away... I've never tried it. >- Changing the properties of an object (but if done with a custom property >sheet, must use the reindex_object command). Nope. If you want the changes to be reflected in the catalog, you must create your own custom property sheet and call reindex_object in your change DTML method. >I'm confused about the reflected changes, however, because there seems to be >two distinct operations in the catalog that may or may not be part of the >automatic updating process: > >- Indexing the object (locates the object(s) and gathers all the relevant >index information). >- Updating the catalog (adds the relevant index information to the catalog). When you perform "Find"s to the Catalog or click the "Update Catalog" button, I think CatalogAware ZClasses will act just like any other type of objects. CatalogAware basically adds the Add/Delete hooks and a couple useful functions (like reindex_object). >Okay. What is actually happening in my application is that when I add one >of my ZClass objects (inherits from _ZClass_for_CatalogAware and >_ZClass_for_Folder, in that order), my catalog does NOT automatically >reflect the addition. This sounds strange. I haven't had this problem... From what I've seen, my CatalogAware objects have added themselves just fine. I've never inherited from Folder, though. I have used ObjectManager, and that has worked fine. Kevin

multiple ZCatalogs
by Tim Wilson 21 Sep '99

21 Sep '99

Hi everyone, Is it possible (or preferable) to have more than one ZCatalog instance? Specifically, I'd like to index some images for the purpose of collaborating with some other people on a project. There's no reason why these images would need to be available anywhere else on the site. What's the best way to handle this? -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.
