catalog object owners?
by Tim McLaughlin 27 Feb '01

27 Feb '01

Anybody know how to catalog the object "owner"? I can't seem to find a property to catalog the value of getUserName(). (of course I could always kludge it with a property in the constructor, but I would prefer use what is already there). ___________________________________________________________ Tim McLaughlin BCSwebservices.net Director, Technical Group 1950 Old Gallows Road tel: (703) 790.8081 x111 Suite 201 tim(a)bcswebservices.net Vienna, VA 22182 www .bcswebservices. net

How to build indexes in the MemberCatalog of Membership Component?
by Dirksen 27 Feb '01

Hi Bill, When I open the 'find objects' tab in MemberCatalog, I can't see 'PortalMember' in 'find object in type' selection field. How to build indexes then? Thanks in advance!

strip_html?
by R. David Murray 26 Feb '01

26 Feb '01

I searched the NIP archives but didn't get any hits on strip_html. Is the code for this beast (used by zope.org to strip html out of partial text included from another page) available anywhere? --RDM

'getObject' forces you to "wake up" the catalogued object; in a large enough result set, the price is pretty punitive, compared to serving the results as cached metadata.

ZCatalog problems
by morten＠esol.no 26 Feb '01

26 Feb '01

Hi guys, I'm having trouble making ZCatalog work. The problem is that there are 29 objects of a given meta type, with the same booleans that should be returned for an iteration; but only 20 are. Is this a result of caching perhaps? Or lazy results? Thanks, Morten

Adding a new property type
by Ausum 26 Feb '01

26 Feb '01

I'm interested at writing a patch for Zope. In adition to the 11 "add property" options bundled with Zope, I'd like to have an "html-editor" type, for wich I already have a working stand alone version. Would you please help me on the steps I need to do to integrate this new property type to Zope? Thanks in advance, Ausum

Zope 2.3.1b1, strange things when ConflictError.
by Erik Enge 26 Feb '01

26 Feb '01

I have two nice methods. One of them (methodA) is called via the web. These belong to one class; classA. class classA: "doc string" def methodA(self): "doc string" objects = self.methodB(self) objects.reverse() attrib = '' for object in objects: attrib = attrib + 'some html' return attrib def methodB(self, object, skip=[], stop=[], objects=[]): "doc string" try: if object.meta_type in skip: return self.methodB(object.getParentNode(), skip, stop, objects) if object.meta_type in stop: raise AttributeError else: # I don't think I need this. if object not in objects: objects.append(object) else: raise AttributeError return self.methodB(object.getParentNode(), skip, stop, objects) except AttributeError: return objects Narrative story: The user calls methodA (from a instance of classA) through the web. methodA returns some nicely formatted HTML navigation links. methodB should traverse through the objects with getParentNode(), append the object in the list objects (if its meta_type is not listed in 'skip' or 'stop' - which are "skip meta_types" and "stop_meta_types" lists) and return them to methodA for formatting. The objects should be listed in the list that is returned sequentially and methodA would be required to do an objects.reverse() to make sure we are facing the right direction. First of all, this doesn't work very nicely. Every other time I refresh my webpage (ie. call methodA) it seems to reverse() the list returned from methodB on its own. That's strange. This results in: [<instance1>, <instance2>] and [<instance2>, <instance1>] every other time. *baffled* Now comes the part which really makes me want to go to my hotelroom and watch Life of Brian on BBC at 9.00pm; if I refresh the webpage quickly, and many times (not too quick or too many times; 2-5 times within 2-5 seconds) I get a ConflictError raised in my log - it doesn't take it up to the webpage. There is other stuff going on which causes the ConflictError to get raised (although, I'm only _reading_ from a ZCatalog, as far as I know anyway). Heres what I don't understand. When ever I get a ConflictError, the contents of the 'objects' attribute in methodB isn't "flushed". Thus, resulting in a very long navigation bar with repeating links. Let me repeat that: The attribute 'objects' of the method methodB appears to be persistent. Which it isn't of course. My best guess is that something is wrong with the logic when a ConflictError is raised. It would make kinda sense. Tracebacks, beers or other interesting things offered if needed. :)
