dtml-tree issue
by Vangelis Mihalopoulos 08 Apr '05

08 Apr '05

Hello, I want to use dtml-tree. I want to populate this tree using an external method that like this one: getChildren(parent_id) => [child, child, child, ......] where "parent_id" is a string and each child is a node (python object). My problem is what kind of object must each node be, in order for the dtml-tree to work properly... The dtml-method is like this (example, hierarchy of links): <dtml-tree id=LINK braches_expr="getChildren(LINK)"> <a href="<dtml-var LINK>"><dtml-var TITLE></a> </dtml-tree> I tried a dictionary, but i cannot retrieve the "LINK" in the branches_expr. I made a class in the External Method with attributes "LINK" and "TITLE", but i get unauthorized exceptions... Thanks for any help, Vangelis

I mean, Plone is a very good *application* but I don't want to be locked on it. Just release a way to convert a Zclass to a Python Product (at least for the simplest ZClasses...). I'm stil stuck on convert that damn base class CatalogAware to CatalogPathAware, just to name something (CatalogAware) which is still there for no reason... :)

RE: [Zope] Product creation difficulty

*grin* true enough. at its simplest level, I've been trying to just import xmlrpclib and use it normally in scripts. I used my __init__.py to allow_module('xmlrpclib'), which has stopped it from throwing security errors. however, when I actually run a test script, I get the following: Error Type: Fault Error Value: <Fault 1: 'exceptions.Exception:method "echo.__roles__.__contains__" is not supported'> error_log has this traceback: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.PythonScripts.PythonScript, line 323, in _exec Module None, line 5, in testXRPC - <PythonScript at /pro4/testXRPC> - Line 5 Module xmlrpclib, line 1029, in __call__ Module xmlrpclib, line 1316, in __request Module xmlrpclib, line 1080, in request Module xmlrpclib, line 1219, in _parse_response Module xmlrpclib, line 742, in close Fault: <Fault 1: 'exceptions.Exception:method "echo.__roles__.__contains__" is not supported'> I can watch the "POST /RPC2" messages increment on my xml-rpc server, so I know the message is getting through. but the xmlrpc server isn't built with Zope in mind, so "__roles__.__contains__" makes it cough a Fault back at me. the code I have in the python script is as simple as: <code> import xmlrpclib server = xmlrpclib.ServerProxy("http://localhost:9999") server.echo('this is a test') </code> echo just sends the recieved string back. it works from command line, but that's not surprising... I could be wrong about where or how it's failing, but the traceback looks like the message is getting there, and returning with the "echo" method having been wrapped in a zope security check, thus faulting at the server...

question about manipulating zcatalog query results
by Ira Sher 08 Apr '05

08 Apr '05

Hello all, I've moved a zope 2.5.1 (python 2.1.3) installation to two newer locations (zope 2.7.4/python 2.3.4 and zope 2.7.5/python 2.3.5) and scripts I have that iterate over zcatalog results using 'for' loops now fail with "global name '_getiter_' is not defined." I'm also unable to take the zcatalog result and manipulate it (split or concatenate instances sent to a list) without getting a "Record objects do not support [whatever action]"--even if I've asigned the result to another list and am operating on that list. ie--I used to be able to say: for row in result: res.append(row.id.split().pop(), row) but now can't, and can't even iterate over the list using a while loop, as the split will fail. I've found some reference to the _getiter_ problem on the forum, but the queries date from nearly a year ago, and there were no fixes at the time (save to wait for 7.4 to come out of beta). Is anyone else experiencing this? Is there a workaround? What am I missing? thanks for any help/advice ira

How can i instantiate a external method within my Container Product? I've tryed to do this as following: ... from Products.ExternalMethod import ExternalMethod class Container(Folder): meta_type ='Container' def __init__(self, id, title): self.id = id self.title = title .... index_html = DTMLFile("dtml/indexContainer", globals()) search = PythonScript(id='search') searchService=ExternalMethod('searchService','searchService','search','search') ..... The id and title are "searchService" . The module and function name are 'search' and they are located in Extensions directory in my Container Product. The following error is printed: File "/home/zope/Zope2.7.4/lib/python/OFS/Application.py", line 673, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/home/zope/Zope2.7.4/lib/python/Products/Container/__init__.py", line 1, in ? import Container,ItemSimples File "/home/zope/Zope2.7.4/lib/python/Products/Container/Container.py", line 22, in ? class Container(Folder): File "/home/zope/Zope2.7.4/lib/python/Products/Container/Container.py", line 36, in Container searchService=ExternalMethod('searchService','searchService','search','search') TypeError: 'module' object is not callable How could i solve it?
