underscores in Z SQL Method
by Chad McDaniel 05 Mar '99

05 Mar '99

Hello all, I recently discovered Zope and am diving right in. I have a Z SQL Method with the following Query Template: --- select * from rw_ProjectData where _id =  --- when I test it, I get the following: --- Sorry, an error occurred. Traceback (innermost last): File /usr/people/chadm/work/Zope-1.10.2-src/lib/python/ZPublisher/Publish.py, line 877, in publish_module File /usr/people/chadm/work/Zope-1.10.2-src/lib/python/ZPublisher/Publish.py, line 590, in publish (Info: /test/viewSRR/manage_test) File /usr/people/chadm/work/Zope-1.10.2-src/lib/python/Shared/DC/ZRDB/DA.py, line 302, in manage_test (Object: CopySource) File /usr/people/chadm/work/Zope-1.10.2-src/lib/python/DocumentTemplate/DT_String.py, line 513, in __call__ (Object: <string>) File /usr/people/chadm/work/Zope-1.10.2-src/lib/python/DocumentTemplate/DT_In.py, line 599, in renderwb (Object: viewSRR) File /usr/people/chadm/work/Zope-1.10.2-src/lib/python/DocumentTemplate/DT_Var.py, line 237, in render (Object: _id) KeyError: _id --- I'm guessing that the parsing of the tokens picks up on underscore ('_') even outside of the DTML tags. Does anyone have a solution or workaround? thanks -- -chad

DatabaseError: Corrupted data record...
by Tony.McDonald＠newcastle.ac.uk 05 Mar '99

05 Mar '99

Hi all, Firstly, I'd like to thank everyone for the detailed replies I got to my 'Tough Questions' post. I'll reply individually to you all and try to answer some of the questions that *I* got asked, but as 'they' say... "...there is one small problem!" (MPaTHG) My database has got nuked. I don't know how it happened, but this is the tail of my serve.errors file File "lib/python/OFS/Application.py", line 319, in open_bobobase Bobobase=Globals.Bobobase=Globals.PickleDictionary( File "lib/python/BoboPOS/PickleDictionary.py", line 159, in __init__ db=apply(DBType,(),storage_options) File "lib/python/BoboPOS/SimpleDB.py", line 221, in __init__ self.open(file_name,create,revision_time,meta_index,read_only) File "lib/python/BoboPOS/SimpleDB.py", line 287, in open try: self.index,self.pos=read_index( File "lib/python/BoboPOS/SimpleDB.py", line 1365, in read_index raise DatabaseError, ('Corrupted data record at %s' % pos) DatabaseError: Corrupted data record at 1087646 Trying to 'start' the server again just results in the serve.errors file being touched. As you'll know from my 'Touch Questions' post, I'm a novice in Zope (but I've bought the Lutz 'Programming Python' book, have two more on order and have been reading and rereading the docs all week...so I'm learning fast), but this has me stumped. I haven't got too far into my Zope 'career' yet, so I won't be devastated if I have to replace the database from scratch (how do you do that by the way?), but I'm sorta worried about the way that all my work seems inaccessible to me now. any and all help would be ... appreciated. tone.

DTML Method truth value
by David Ascher 05 Mar '99

The following method tests false (correctly):   But if I change it to:     then it tests true (note that nothing happens in the #in block). Is this correct behavior or one for the Collector? --david

XML discussions
by Robert OConnor 05 Mar '99

05 Mar '99

Hi Paul and Zopesters, Paul writes in the thread: [Zope] Some tough questions about zope... >I've been awfully interested in XML in >the last few days. Can you describe what >user-visible benefits PHP delivers due to its integrated >XML parser? I found a great description about XML in: "20 Questions on XML" http://builder.com/Authoring/Xml20/index.html On Paul's Zope roadmap: (Jan 18th) http://www.zope.org/Information/Roadmap "(2) XML. Zope is a great fit for XML, even better with the machinery from Tabula going in. We also see XML becoming the basis for other initiatives, such as WebDAV and RDF. However, we just can't squeeze out the time to dive in deep. Rather, we'd love to see more community progress like that which popped up this weekend." I did a search for postings that had "XML" in the subject and found 55 messages in ~6 threads between Jan 8th and Feb 2nd Other messages have "XML" in the body. Hopefully we can get some OUTLINE of how ZOPE and XML can work together. --- A framework for further discussions. -bobo connor bob(a)rocnet.com

Simple DTML Method/Acquisition problem
by David Ascher 05 Mar '99

05 Mar '99

I have a standard_html_header/footer pair which works much like that on zope.org. The header inserts a  in the left column. The sidebar DTML method is:    <a href=""></a><p>   (show links to sub-folders which don't have the 'hidden' property set). The above works fine in the toplevel folder. In the subfolder, however, nothing shows up, even though there are two folders which do qualify. I'd tried originally to have it be a DTML Document and change the expr to _.objectValues(['Folder']), but that doesn't work at all. What am I missing? --david

evaluating attribute values
by Robin Dunn 05 Mar '99

05 Mar '99

How can I evaluate a #var equivallent for setting a tag attribute value? For example, Zope doesn't like this:  --> or this:  (it tries to use smtpHost as the host name, instead of its value) Help! -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!
