Could somebody post an example ? You're not too stupid; this isn't documented (yet). Perhaps some people would be inclined to tell you to read the source code and then call you stupid, but not me ;-) The objlink method gets one parameter, which is a DOM Node object (for info on those, look for the docs on the PyXML suite). It is expect to return either a Node object or a string; there is a weird API which allows it to return a dictionary, but you really don't want to use that before the documentation is in place.

I wrote flat database because I wanted some features ListMate didn't have
and didn't want ZClasses. I basically copied the structure from ListMate,
so it's probably not the best design possible for ZPatterns. So (1) may not
be possible with the current code.
Maybe try creating entries like so:
...
manage_addEntry doesn't return the new entry.
Idon't remember how this works anymore, frankly. The source code is your
friend :)

[Zope-dev] Flat Database/ZPatterns api, performance ?
Flat Database (was ListMate) is just what I need to whip up an
interface for non-technical administrators - thanks. So I migrated two
data tables ("workshops" & "registrations") from gadfly to flatdb
instances using the CSV import feature, and the admin interface is
working fine.
I'm having a hard time, though, figuring out how to access the data
programmatically. I scavenged the docs (zpatterns wiki very helpful,
as far as it went; not much available for flatdb), searched the lists
(nothing) and grovelled around in the code. I'd appreciate any
comments or advice on the following.
1. how can I look up a row in the table by column value, other than
searching the whole table: ?
2. how can I add an entry to a table ? I tried this:
...
and it seems to create a number of spurious rows with only the first
field set. This didn't work either:
3. displaying table contents seems quite slow. On this P100 with 48Mb
ram doing nothing but zope, no load and generally snappy, generating
the 50-row, 20-column registrations table listing takes 15
seconds. Any ideas about where this comes from ?
4. this is my first encounter with the mighty zpatterns. I wonder how
one might add a thing (data plugin ?) so that FlatDb could read the
data out of zgadfly or something faster, instead of migrating it as I
did ?
Many thanks!
-Simon

[Zope-dev] Path Handler problems
Hi, I've finally gotten around to doing the PathHandler product I mentioned ages ago and now I've run into problems. Since it's so short, here's the product class: class PathHandler( SimpleItem,Persistent,Acquisition.Implicit ): meta_type = 'Path Handler' def __init__(self, id, method_name, title=''): """initialise a new instance of Path Handler""" self.id = id self.title = title self.method_name= method_name def __bobo_traverse__(self, TraversalRequest, name): list=copy(TraversalRequest['TraversalRequestNameStack']) list.reverse() TraversalRequest['path_to_handle']=[name]+list TraversalRequest['TraversalRequestNameStack']=[] return getattr(self,self.method_name) Okay, the confusing bit first. Let's say x is an instance of PathHandler, with method_name = 'the_method'. the_method is a DTML method as follows: If I try the url: http://localhost:7080/x ...I get: Resource not found Traceback (innermost last): File E:\Zope\2271B4~1.2\lib\python\ZPublisher\Publish.py, line 222, in publish_module File E:\Zope\2271B4~1.2\lib\python\ZPublisher\Publish.py, line 187, in publish File E:\Zope\2271B4~1.2\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File E:\Zope\2271B4~1.2\lib\python\ZPublisher\Publish.py, line 173, in publish File E:\Zope\2271B4~1.2\lib\python\ZPublisher\HTTPResponse.py, line 308, in setBody File E:\Zope\2271B4~1.2\lib\python\ZPublisher\HTTPResponse.py, line 529, in notFoundError NotFound: (see above) If I try the url: http://localhost:7080/x/1 ...I get what I expect, the output of the_method, with path_to_handle set to ['1'] Now, if I try the following url or anythong longer: http://localhost:7080/x/1/2 ...I get: Zope has encountered a problem publishing your object.

So, a python x can be bound to containment _or_ context depending on how it's setup, right? Okay, if that's the case, then we need to make sure that the situations where you use context binding and the situations where you use containment binding are clearly explained. If Zope is to succeed really well, we should make sure that people at the bottom of the bell-curve don't end up feeding paper to hippos or filling receptions with hippo feed ;-) It's bad if someone rises up the bell curve and then realises all their context-bound methods could be badly abused, they're left feeling stupid and with the impression it's easy to create serious problems with Zope. By the time they've first learn to use python x's, they should know when to use context and when to use containment. > I'm arguing that we need a name that makes sense to > everybody.
