catalog reindex question
by Sean Kelley 25 Sep '03

25 Sep '03

I have a question about catalog indexing. I have a product that when and item is edited, the catalog listing shows the item twice. Once with info from before editing and once with the updated info. The python script which is editing the item has the lines: self.reindex_object() if REQUEST is not None: return self.index_html(self, REQUEST) Is there a mistake here? How does one update the catalog correctly? I am using zope 2.4.3

by Paolo Dina 25 Sep '03

Hi guys. I have developed a web site using Zope version 2.6.1. Now that site is ready to go online. Which version of Zope should i install in production environment? Do you suggest to stay on 2.6.1 or instead, to use the newer version 2.6.2? Do you think that the migration could cause problems? Thanks Paolo Dina

Hi, I have a product where I am using the following method to display a page: def index_html(self, REQUEST=None): "Method to show my web page" Content_Main = PageTemplateFile('showMyPage.pt', _wwwdir) setattr(myClass, 'Content_Main', Content_Main) if REQUEST is not None: return self.Template_index_html(self, REQUEST) I would like to modify this to have it duplicate the behavior of the following url: http://www.mysite.com/myClass/index_html#myID Where myID is defined in showMyPage.pt by <p id="myID"> some text </p> How would I accomplish this? Thanks, Mike

Help! I installed Zope on a RH8 box a few weeks ago and it has run ever since :-) But, today I up2dated mysql and now Zope will start but within a few seconds it shuts down again (if it ever started?) No messages in /var/log/messages Worst nightmare. It won't run and I can't find any clues. Any pointers? Simon

Re: [Zope] 'Delete objects' permission
by Tim Terlegård 25 Sep '03

> However, for "Owner" is would be unintuitive that the owner > of a folder has "Owner" permissions on all contained objects... Yes, unintuitive and it makes it hard to only allow creaters to delete their own objects. I thought this community policy was common... > > Is there any website explaining this thorougly? > > Did you read the local roles chapter of the Zope Book? I can't find any chapter named 'local roles'. I read "Users and Security" though. I grasp local roles now and with a little help by Chris on IRC I understand 'Delete objects' permission on folders. My conclusion is that there's no way to have a "members can create objects on the entire site, but only delete their own ones"-policy without scripting. I figure there are two ways: * Create a script that adds 'Delete objects' permission to the object's container in manage_beforeDelete or similar. You also have to add a script that removes 'Delete objects' after the deletion have been made. * The same solution, but using workflow instead. Maybe workflows use manage_beforeDelete for the work behind the scenes? Maybe there are better ways? These are not easy solutions for a newbie like me :) Tim

running a External Method via ZEO
by alan runyan 25 Sep '03

25 Sep '03

Hi. I've spent about 2 hours trying to get this to work. This is *so* frustrating I can not begin to tell you. I have a External Method. A pre-populate Data.fs. I merely want to execute this external method. But the problem is I can not get the INSTANCE_HOME and SOFTWARE_HOME "Products" folders to import into the same namespace. I guess Zope is doing some really magical *!4@ to get everything available in the Products namespace. could someone please explain to me this magic? running: import os import sys sys.path.append('/var/zope/zope/lib/python') sys.path.append('/var/zope/test') os.environ['INSTANCE_HOME']='/var/zope/test' os.environ['ZOPE_HOME']='/var/zope/zope' def main(): import ZODB import ZEO.ClientStorage, os, string import OFS.Application import App.ProductContext host=os.environ.get('ZEO_SERVER_NAME', '') port=string.atoi(os.environ.get('ZEO_SERVER_PORT','21894')) MB = 1024**2 Storage=ZEO.ClientStorage.ClientStorage((host, port), client='us.plone.org', name='plonedotorg') zodb=ZODB.DB(Storage) connection=zodb.open() root=connection.root() import pdb; pdb.set_trace() app=root['Application'] app.reset() connection.close() if __name__=='__main__': main() I get: Traceback (most recent call last): File "reset_test.py", line 32, in ? main() File "reset_test.py", line 28, in main app.reset() File "/var/zope/Zope-2.6.2b3- src/lib/python/Products/ExternalMethod/ExternalMethod.py", line 231, in __call__ return apply(f,(self.aq_parent.this(),)+args,kw) File "/var/zope/test/Extensions/daily.py", line 30, in reset_env Portal.manage_addSite(self, 'plone.org') File "/var/zope/test/Products/CMFPlone/Portal.py", line 361, in manage_addSite p = gen.create(self, id.strip(), create_userfolder) File "/var/zope/test/Products/CMFPlone/Portal.py", line 344, in create self.setup(p, create_userfolder) File "/var/zope/test/Products/CMFDefault/Portal.py", line 285, in setup self.setupTools(p) File "/var/zope/test/Products/CMFPlone/Portal.py", line 310, in setupTools addCMFPloneTool = p.manage_addProduct['CMFPlone'].manage_addTool AttributeError: manage_addTool thanks, alan

ZODB Persistence problem
by Emiliano Marmonti 25 Sep '03

25 Sep '03

Hello all I'm trying to do an application that handles it own ZODB database for storing large hierarcichal data. The abstractions and the db access are in external method and I use DTML for querying and receiving data to store. I have seen some examples like that about using ZODB from outside of Zope. I have integrated the database with a catalog to search inside it. Now I have a problem that have no idea how to fix it. Could add objects into a ZODB separate database, could add the catalog and the index, but when the database has one element, with every operation (inclusive opening it) this message appears from Zope: 'App.PersistentExtra' module has no attribute 'Autor' >From Python File C:\Archivos de programa\Zope\lib\python\ZODB\Connection.py, line 534, in etstate File C:\Archivos de programa\Zope\lib\python\ZODB\Connection.py, line 178, in_persistent_load (Info: ('\x00\x00\x00\x00\x00\x00\x00\x0e', ('App.PersistentExtra', 'Autor'))) File C:\Archivos de programa\Zope\lib\python\ZODB\Connection.py, line 138, in __getitem__ (Info: ('\x00\x00\x00\x00\x00\x00\x00\x0e', '((U\x13App.PersistentExtraq\x01U\x05Autorq\x02tq\x03Nt.}q\x04(U\x02idq\x05U\x0822596451q\x06U\x04nameq\x07U\x0f Juana Silviaq\x08U\robservacionesq\tU\x0bpruebaq\nu.'))

Somebody knows where could I find an example (that works and is updated) for doing this kind of tasks? My code is: ----------------------------- import sys import ZODB import Persistence from Persistence import Persistent from ZODB.FileStorage import FileStorage from Products.ZCatalog.Catalog import Catalog from Products.PluginIndexes.FieldIndex.FieldIndex import FieldIndex class Autor(Persistent): id='' name='' observaciones='' def __init__(self,id,nombre,comments): self.name = nombre self.id = id self.observaciones = comments def setName(self,nombre): self.name = nombre def setId(self,id): self.id = id def setObs(self,comments): self.observaciones = comments def getName(self): return self.name def getId(self): return self.id class Autores: def __init__( self, file='dcAuthor.fs' ): self.file= file self.db = ZODB.DB( FileStorage( file ) ) self.co = self.db.open() self.root= self.co.root() if self.root.has_key( 'cat' ): self.cat= self.root['cat'] else: self.cat = Catalog() ### This is, how I get it to work self.cat.aq_parent= self.root self.root['cat']= self.cat ### Add indexes to the Catalog-Class ### The names must match the fields of the Person-Class! indice = FieldIndex('id') self.cat.addIndex('id',indice ) otroIndice = FieldIndex('name') self.cat.addIndex('name' ,otroIndice ) ### self.cat.addIndex('observaciones','FieldIndex' ) get_transaction().commit() def setAutor( self, autor ): uid= id( autor ) self.root[uid]= autor print "Guardada como:"+str(uid) ### Let the Catalog know from this object self.cat.catalogObject( autor, uid ) get_transaction().commit() def searchAutor( self, **kw ): r= self.cat.searchResults( kw ) paths= self.cat.paths root = self.root k= [] for i in r: id= i.data_record_id_ k.append( root[paths[id]] ) return k def close ( self ): self.db.close() def AddAutor(nombre,documento,obs): autor = Autor(documento,nombre,obs) autores = Autores() autores.setAutor(autor) autores.close() def GetAutor(expresion): autores = Autores() listaAutores=autores.searchAutor(name=expresion) autores.close() listaretorno=[] for au in listaAutores: listaretorno.append(au.getName()) return listaretorno ---------------------------------------- I've seen that if I no close() the database, only obtain Error 500 from the server. GetAutor and AddAutor are called from DTML. Well, thanks a lot. Emiliano.
