Who can help me, it is very important. Thanks a lot P.S.: My product files are atteached and sorry for my english

"Views" in ZClasses
by Jason Spisak 19 Apr '00

19 Apr '00

Is the "Views" tab in Zclasses set to only allow you to see DTMLMethods/DTMLDocuments? I have a class that sub lcasses ObjectManager and, although I can select it as a 'View', it doesn't show up as a tab in the management interface. All my best, -- Jason Spisak 444(a)hiretechs.com

It does in one I just checked out from the Public CVS, did you pass -d to cvs? This is how I update: cvs -z7 -q up -P -d -Michel

(At least it is not updating the >field indexes like I would expect.) (I moved this to zope-dev because I don't think it is a content-managers question...) I'm having the same problem. I call self.reindex_object() at the end of my edit method, but the catalog does not get updated. If I call reindex_object by tacking it onto the end of the URL for my object, the catalog gets updated. Is there a trick to getting reindex_object to work from a python product? I'm using the default catalog name, by the way. I'm running Zope 2.1.6, and I note that there was an exchange earlier about a possible problem in 2.1.6 where from a ZClass someone found they could not call reindex_object directly but had to use a redirect. Sounds like a variation on the same problem...anyone have a clue? --RDM

Credit-Card handling in Zope (thread progamming?)
by Itamar Shtull-Trauring 18 Apr '00

18 Apr '00

I'm starting to research CC handling, and it seems the way CCVS works is that when you ask for a CC to be authorized, you don't get immediate feedback on success/failure. Instead, at some point the status changes to "authorized". I need to authenticate the CC, and do different actions depending on the result. Since this is going to be run non-interactively, I don't want to have a thread waiting around polling to see if the CC was authenticated - I need, I think, a new thread that does that and does a callback when the authorization is finished. Is it possible to mix threads in Python with Zope? Alternatively, the CC handling can be done by a different python program that does callback via, what - XML-RPC? The monitor? -- Itamar S.T. itamars(a)ibm.net

You could have a separate task handle the CC transaction, and write an entry to a database when it's done. Then have a Zope page that checks for the transaction being complete - if not, it puts up a "please wait" and redirects to itself after 3 seconds.

<dtml-in> how do I get count of records in sequence? (aka batch-size)
by Brad Clements 18 Apr '00

18 Apr '00

I want to be able to do something like this: <dtml-in "GetDB()[Table][Indice][Rec].fetchall()"> <dtml-with "_['sequence-item']"> <dtml-if "_['sequence-size'] == 1"> <dtml-var "tableFromView(URL=URL0)"> <dtml-else> <dtml-var "tableFromView(viewName='DefaultLocatorView',URL=URL0)"> </dtml-if> </dtml-with> </dtml-in> That is, produce different output depending on the number of items returned from dtml-in. There isn't a "sequence-size" variable. I thought "batch-size" would work, but that doesn't seem to exist either, even when I use "size=nn" in the dtml-in statement. I know I can use total-nnn, but then I need to know an attribute name. In this case, I do *not* know any of the attributes in the objects returned from fetchall(). Therefore I'm stuck doing something like this: <dtml-if "_.len(GetDB()[Table][Indice][Rec].fetchall()) == 1"> <dtml-var "GetDB()[Table][Indice][Rec].fetchone().tableFromView(URL=URL0)"> <dtml-else> <dtml-in "GetDB()[Table][Indice][Rec].fetchall()"> <dtml-with "_['sequence-item']"> <dtml-var "tableFromView(viewName='DefaultLocatorView',URL=URL0)"> </dtml-with> </dtml-in> This is ugly, and unlike SQLMethods, the value returned from fetchall() is not cached. (not sure if DTML caches the result of the call or not) FYI, I'm using SQLDict.py here, and its very nice. Next step is to emulate a DB interface using Zope Database Adapters. This way I can test my core logic outside of Zope, but work with the transaction machinery inside zope.
