Hi, I working on an structure like this: folder1 | folder11 | folder111 I have some objects in folder111 which I want to pass as parameters to a dtml method in folder1 (two levels above). I tried something like: <dtml-with "PARENTS[2]"> <td><dtml-var "mtdCreate(_.None, _, qry_item='par1',qry_table='par2', list_name='par3')"> </td></tr> </dtml-with> where par1 and par2 are strings and par3 is an object in folder111. mtdCreate is in folder1. it doesn't work... How can I do that ------------------------------------------- E-mail enviado pelo servidor do CEFETCampos

RE: [Zope] Version Lock Error

When the users hit a DTML method that tries (maybe in a roundabout way, have a ZCatalog?) to write to an object in the ZODB that's been locked in a version, you'll get this. Try to figure out where it's happening by examining the DTML method that they're hitting and figure out where you're trying to do writes. > -----Original Message----- > From: ksmith(a)web-oats.com [mailto:ksmith@web-oats.com] > Sent: Thursday, June 29, 2000 6:04 PM > To: zope(a)zope.org > Subject: [Zope] Version Lock Error > > > Hello, > > For some reason anonymous users are getting locked out > of the site when I try to use versioning. > > It doesn't happen right away, only after I've made a > few changes. > > Does anyone have any ideas on what's happening?? > > Thanks in advance. > > Kevin Smith > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

This would be consistent with "atomic updates." What it means is that a transaction is not written to the Data.fs file until it has completed, and when it is finally written out, it's done as an atomic operation, i.e. at the system level it is a single write operation and nothing else happens on the system until it completes. >From that you can infer that if you were reading the Data.fs file (making your backup copy) at the same time, it would be impossible to read the file "in the middle of an update." If both read and write requests hit Data.fs at essentially the same time, one goes first and the other waits until the first completes. So if the write gets first shot, the read will block until the write (meaning a completed transaction/update) finishes, and your read will include that last update. If your read gets first shot, then it will not include the update. You will under no circumstances get *half* an update. One of the other things that makes this possible is ZODB being of a "journaling" nature. i.e., all updates are *appended* to Data.fs. This is why you must periodically pack the database, which conglomerates all the updates back into the base datastore (or whatever those wacky Zopistas call it. ;) that comprises the first part of the Data.fs file. I think that's all correct. Someone please throttle me senseless if not. :-) -cw-

Version Lock Error

Hello, For some reason anonymous users are getting locked out of the site when I try to use versioning. It doesn't happen right away, only after I've made a few changes. Does anyone have any ideas on what's happening?? Thanks in advance. Kevin Smith

The boss says he couldn't install Zope on our Win2000 box. He tried 3 times. Anybody else have a problem with M$'s latest? -- Robin Becker

True, but the stored procedure I am calling is intended to return many rows of data (tens of thousands on occasion). I need a cursor for that. >On Thu, 29 Jun 2000, David A Lipsky wrote: >> curs = conn.cursor() >> conn.procedures.some_stored_procedure(curs) > > Do not pass cursor - pass parameters to the procedure and it returns a >result. > >Oleg.

[lines] element in "property sheets" ++ \345 29 \345r ..
by Jørgen Skogstad 29 Jun '00

29 Jun '00

Kindest.. I have object contained in ZObjects .. and I have some object "parsing" the contents based on a search.. The type in the property sheet is; [text] Beneath is the dtml code used to print the main content of the type mentioned above .. <tr><td><b>Annonse tekst:</b></td><td><dtml-var annonse_tekst newline_to_br></td> .. my problem is that the final output when parsed with the dtml code above is something like; ['hei', ' jeg er .. p\345 29 \345r som s\370ker ..... ...angre seri\370st ment. ']</td> .. how do I get ouput without the ['<text>'] .. entries.. that is; "clean output" .. as well as how can i get the ascii codes like \345 to be the correct html code for norwegian caracters? Would apriciate any input here.. Thanks in advance. Kindest, Jørgen Skogstad

I wrote: If a folder doesn't itself contain a required object or method, I'd like to have another folder looked in instead. The fall-back folder won't necessarily (and often can't) be higher in the hierarchy, so acquisition doesn't seem to be a solution.

Steve, thank you very much for that information.

Though I have a reasonable amount of Python experience, I'm just starting on Zope development. Depending on how I get on, I may take you up on your offer!
