How to hook __before_publishing_traverse__
by Sidnei da Silva 30 Jan '02

30 Jan '02

Reading the documentation, i found out why i could not set permissions on the before_publishing_traverse. It seems that at this point, getting SecurityGetUser its not reliable. So, i was thinking of a way to test for if a role is valid to access an object. Maybe Security.validate() or something, i dont know. And if theres a hook for testing when a property is accessed, like testing for some condition before returning title_or_id. Something like __before_property_access__.

Using Zope 2.5 beta 1. I followed the automatic cataloging example in the Zope book. Yes the first class is CatalogAwareBase ZObject, CatalogAwareBase, ZDTMLMethod Catalog indices are text indices set to one two three Catalog metadata is set to one two three Catalog find_object is set to my_aware_object my_aware_object properties are one two three Yet when I add a new instance of the my_aware_class the catalogue is not updated. What am I missing, Chris

I believe they made a switch from connect(server,port) # 2 arguments to connect((server,port)) # note the tuple -- 1 argument! a couple Pythons ago. Try changing that in the source and seeing if it corrects the problem. ---------- Keith J.

id of an externally created object
by Stephan Zaulig 30 Jan '02

30 Jan '02

Hi List, if i create a new object in an external method with following code, the object is created without any exception and i can see it in the management interface of Zope with id and title. newob2=self.Control_Panel.Products.SQS_Library.Book(id2) newob2.propertysheets.InstanceProperties.manage_changeProperties(REQUEST) But if i iterate over it like this <dtml-in objectValues> <dtml-var id> </dtml-in> i dont't get the id of the object. It's no problem, cause if i add this line of code in my external method everything seems to be alright. newob2._setId(id2) My question: Is this behaviour ok, and if it is, could anybody explain to me why it is like this? Thanks, Stephan ______________________________________________________________________________ Die schönsten Ski-Regionen der Alpen - jetzt bei Ferienklick.de http://ferienklick.de/ski/?PP=2-5-100-105-38

Whois tag help
by Norman Khine 30 Jan '02

30 Jan '02

Hello, I am trying to figure out the whois function to use within zope. I have a form trough which I can add the domain and suffix, but I can't seem to get it working, either with an external method or a python script. Also the whoistools-0.1.0, don't seem to work correctly, I get this error when testing through python Python 2.1.1 (#1, Aug 25 2001, 04:19:08) [GCC 3.0.1] on sunos5 Type "copyright", "credits" or "license" for more information. >>> import whois >>> print whois.Whois("python.org") Traceback (most recent call last): File "<stdin>", line 1, in ? File "whois.py", line 80, in Whois sock.connect(server, port) TypeError: connect() takes exactly 1 argument (2 given) although if I do >>> print whois.Server("python.org") whois.crsnic.net >>> It works!!! Any help would be much appreciated Regards Norman

There is no methods or functions to check the attribute of result from ZSQL ?_? Right?
by Terry 30 Jan '02

30 Jan '02

Hello friends, It had spend days on Google, Zope Site, and ask question on the list (Many thanks to people on the list) ? But It's infructuous.(I came from Perl,PHP , the origin web script langage background, I try to enjoy the fun you guys already had.) I just hope to solve a easy question. I really couldn't find any method or function in Python Script to check a attribute exist or not. I couldn't just simply to ckeck the attribute in Python Script. if test(result_object_from_ZSQL[0].ph_id): if result_object_from_ZSQL[0].ph_id: #My Python Script########### results=script.sql_Get_News(ar_id=ar_id,ar_publish='Y') # get article from MySQL photo=script.sql_Photo(ar_id=ar_id) # get photo's datd from MySQL pull=script.sql_Pull(ar_id=ar_id) # get pull box=script.sql_Box(ar_id=ar_id) # get box print results.names(),'<p>' print photo.names(),'<p>' print pull.names(),'<p>' print box.names(),'<p>' ############################## I mix photo , pull , and box to one list, temp_glue[]. then I would process the temp_glue[] , so I have to knew each item originally came from which table. So I use the following lins to check. ####### Check each item for i in range(len(temp_glue)): if temp_glue[i].ph_id: print "This item came from Photo Table" if temp_glue[i].pl_id: print "This item came from Pull Table" if temp_glue[i].bx_id: print "This item came from Box Table" ###################### Terry

RE: [Zope] Zope's database capability

One option we've considered is storing information in volatile RAM, then flushing it out to the ZODB every now and then, perhaps by a separate thread to prevent page generation from slowing down. This could work if some loss of data is acceptable (if the server is shut down or crash, some unflushed/unsaved data will be lost), for example information related to the usage of a website: - page counters - clickstream logs - implicitly gathered personalization profiles If you use ZEO you'll get into additional problems of each ZEO client having its own volatile RAM storage that needs to be synced via the ZODB or via some other network protocol.

Are there other solutions for counter-like apps than an RDBMS or the file system? (We don't wanna give Zope file system access for maximum security... ) Do I really have to set up an RDBMS and a table for small, tabular, frequently changing data? Can I do this with non_undo dbs? Is the write process slow because of the undo feature?
