Recataloging object instances
by Jean Jordaan 13 Nov '01

13 Nov '01

Hi all In the 'handlemail' method that is called for incoming mails, I have roughly the following code:: apply( mail_folder.manage_addProduct['ZMailIn'].manage_addZMailMessage , new_mail_args , {} ) zmail.manage_addProperty('status', 'unassigned', 'lines') ZMailIn subclasses CatalogAware, so the new instance gets cataloged. However, the 'status' property that I add after creation does *not* get cataloged. (It does get cataloged when I manually update the catalog.) In order to get the 'status' property cataloged, I added the following two lines:: ZMailInCatalog.uncatalog_object('/' + zmail.absolute_url(1)) ZMailInCatalog.catalog_object(zmail, '/' + zmail.absolute_url(1)) My question is this: why do I have to add the leading slash, here? 'manage_addZMailMessage' catalogs the instance as '/mail_folder/zmailNNN', and 'absolute_url(1)' returns 'mail_folder/zmailNNN' (without the leading slash). Another question: shouldn't the added property automatically get cataloged, without 'uncatalog_object'/'catalog_object' being called explicitly? I'm on Zope 2.3.2 on Linux .. Regards, Jean Jordaan

RE: [Zope] Experience with Zope and Access ?
by Schmidt, Allen J. 13 Nov '01

On Windows I use mysqlfront to play with my MySQL server. First I tried the probable offending query in the TEST panel in Zope. Took about as long as the page itself takes to load. Then I pulled the query and put it into the mysqlfront query panel and replaced the dates and date calculations with hard coded 'dates' (really just strings) Still takes the same amount of time to run. Now I know where the problem is.....Looks to be a query optimization problem. Odd, though, that the same query - verbatim - FLYS using Access/ODBC! Go figure... Allen

Getting SQL record names in python script?
by azbok＠yahoo.com 13 Nov '01

13 Nov '01

I call a ZSQL method in python and successfully retrieve the results I want. Then I want to get a list of the field names. I try MyRec = context.GetRecord() print MyRec[0].keys() I get Error Type: AttributeError Error Value: keys I can cycle through the values no problem. I thought the records returned were each a dictionary. Is keys one of those functions that is restricted? How would I get field names? Thank you very much

Serving Large PDFs
by Edmund Goppelt 13 Nov '01

13 Nov '01

I have many large pdf files which I would prefer to serve from Zope, rather than Apache. Unfortunately, Zope 2-3-1 doesn't appear to do byte-serving (i.e., it can't load a particular page of the pdf, just the whole thing). Has anyone else run into this problem? What did you do about it? -- Ed Goppelt

Defining meta_types
by Jesper Holmberg 13 Nov '01

13 Nov '01

Hi all, I've created a Product Step which is a subclass of Folder. I want restrict what types of objects I can put in an object of type Step. The "Developer's guide" has this to say on the subject: "If you wish to control which types of objects can be contained by instances of your product you can set the meta_types class attribute. This attribute should be a tuple of meta_types." I naively interpreted this such that I could put this in my class: meta_types = ('Step', 'SURef',) But this gives me the errors: Error Type: AttributeError Error Value: has_key With the backtrace: File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 271, in filtered_meta_types (Object: Step) So I found a tip on the Web, saying I could do this: meta_types = ({'name':'Step', 'action':'manage_addStepForm'},) Now, this doesn't give me an error, but the effect is that I get one more Step as alternative on the drop-down menu "Select type to add..." *in addition* to all the alternatives. But I wanted to restrict the possibilities, not augment them. What am I doing wrong?
