Plone: storage, catologing and versioning
by Rogério Atem de Carvalho 24 Jul '05

24 Jul '05

Hi, I have a few questions about Plone (in some extent CMF/Zope): 1)How to manipulate versioning in Plone? (like CPS does) I know there is PLIP8, but it is still a proposal, isn't it? 2)How to store and catalog huge document collections? -LocalFS + ZCatalog? -Implement mapping and indexing in a relational DB? (I have also de ERP5's ZSQLCatalog option...) 3)Is there any product or Plone plug-in that allows enhanced searches through thesaurus or ontologies, or something like this? I know there are Ontobroker and Gnowsys, but I would like to have something simpler to work on top of Plone. thanks for the help, -- Prof. Rogério Atem de Carvalho, D.Sc.

zoperun vs start and ssh
by virgil huston 23 Jul '05

23 Jul '05

This may be a stupid question, but, after searching the archives to find out how to keep Zope running after starting and then disconnecting from a remote ssh session, nothing works. First, the Zope manual and all the archives messages talk about using ./start. That doesn't work for me unless I am just in the wrong directory. I am running ./zoperun from /bin. Using nohup and & doesn't keep Zope running when I log off my remote session. Any ideas? Thanks. Virgil Huston

Searching Content Objects in Zope 3
by Jim Vine 23 Jul '05

23 Jul '05

Hello, I've been working away on an application, and it's now starting to take shape, based around a series of content objects. As recommended on this list I opted for Zope 3 to build my app, and I'm finding it quite powerful. However, I've hit a bit of a brick wall around searching. It seems from the documentation that ZCatalog is the prefered way of doing a search in Zope 2, but that this isn't implemented in Zope 3. I've got Philipp von Weitershausen's (very good!) book, and he doesn't implement a search for his recipe objects. I've also been looking at the PDF of the Zope 3 Book (which I've also found really useful) and I haven't spotted searching of objects mentioned in that. My search tool will need to take various criteria (say, number of bedrooms, maximum rent, areas the property can be located in) and scan through my objects to find all the matches. I think I can work out how to search through the objects themselves in order to find the matches, the real problem is taking in the criteria in the first place. (Although, any tips provided on the searching side of things would certainly be welcome too!) As a 'dummy run' at searching I created a View for my PropertyFolder object that shows properties based on specified criteria - I can get this to work OK, but I have to put the criteria right into the Python code, so clearly that's not acceptable... I would be grateful for anything anyone could point me to that would help me to build a tool to search my content objects. Philipp mentions the use of Utilities for searching, but beyond that, I don't know where to start. Is it possible to use Interfaces to create data entry schemas/forms for Utilities in the same way as for objects? Any help, greatly appreciated.

Take a look at the unit tests which exercise the FSZSQL code, there is a sample one that is part of the fake skins directory used by the CMFCore unit tests: http://svn.zope.org/CMF/trunk/CMFCore/tests/fake_skins/fake_skin/ testsql.zsql?rev=37165&view=markup > I can't give this information because it doesn't raise exceptions. > It works (not raise errors), but not properly. > > I never saw an example of ZSQL Methods running from file system in > CMF, can you give me this? > > My intention is just contribute, however, solving a real problem I > have. You're still giving no clue about what exactly it is that works "not properly". jens

tal:attributes question
by Erik Myllymaki 22 Jul '05

22 Jul '05

I am trying to set the bgcolor of a page based on the existance of a variable. Neither of these seem to work: <body tal:attributes="bgcolor python:test(hasattr(options, 'error'), 'red', 'green')"> <body tal:attributes="bgcolor python:test(hasattr(request, 'error'), 'red', 'green')"> I can access the error variable with this: <p class="error" tal:condition="exists: options/error" tal:content="options/error | nothing">There was an error</p>

I can't give this information because it doesn't raise exceptions. It works (not raise errors), but not properly. I never saw an example of ZSQL Methods running from file system in CMF, can you give me this? My intention is just contribute, however, solving a real problem I have. -- Jean Ferri TcheZope.org

zpt and sql
by Nicholas Wieland 22 Jul '05

22 Jul '05

Hi *, I've searched a lot but actually didn't find anything useful to solve my problem, and probably I haven't really understood how Zope works ... :) I'm developing a filesystem product and I need to display a zpt form where I display some results from a query. I'm able to query the DB, and I'm able to display an empty zpt form, qhat I don't understand is how to stick the two things together. This is what I have: class InstitutionalReport (Item, Implicit, Persistent, RoleManager, Folder): """ Base class for InstitutionalReport. """ meta_type = "Institutional Report" manage_options = ( {'label' : 'View', 'action' : 'index_html' }, ) def __init__ (self, id, conn_id): """ initializer """ self.id = id self.conn_id = conn_id self.sqlGetReferenceDate = SQL ('slGetReferenceDate', '', conn_id, '', _sqlGetReferenceDate) #Folder.manage_addPageTemplate (self, 'index_html', file = self.def_index_html, REQUEST = None) index_html = PageTemplateFile ("zpt/index_html.pt", globals ()) I want to cycle through the query result with ZPT and populate a select.

object acquisition via python scripts
by Jon Bowlas 22 Jul '05

22 Jul '05

Hi, I'm not sure if the subject line accurately describes what I'm trying to do, anyway let me try and explain. I have a set of folders like this: Site root object |---- Attributes object |---- Layout ZPT |---- get_attobject (python script) |---- get_attributes (python script) |---- Folder object A |-----Attributes object |---- Folder object B My 'get_attobject' script is called from my 'Layout zpt' using this code: <div tal:define="attobject here/get_attobject"></div> And my get_attobject script contains the following code: attobjects = context.objectValues('Attributes object') if attobjects: return attobjects[0] return None Then my get_attributes script uses the attobjects value returned from the get_attobject script to output the values of the 'Attributes object'. Now this all works fine in the 'Site root object' and in 'Folder object A' but when I get to 'Folder object B' there is nothing returned since I have no 'Attributes object' present. But what I'd like to do in this situation is use acquisition to retrieve the values from the parent 'Attributes object' located in the site root. So could someone please explain how I could achieve this? Hope someone can help me, many thanks. If any more information is required please ask. Jon
