[Zope3-Users] generations and utilities
Hello,
I've developed a content object for zope and I'm using the install.py
script in a generation package to install some prebuild content
instances in a folder, and everything works well.
I'm now trying to add a Catalog plus IntIds to do some search... but I'm
doing something wrong...
I cannot find the right way to install an IntIds (at least!) in the
global site (I don't care about local sites) and populate the
application via a generation install.py
Must I move the IntIds and Catalog instantiation/registration outside
the script?
def evolve(context):
Install an articles folder full of pre-made articles
root = context.connection.root()
app = root['Application']
# app is a ISite...
assert ISite.providedBy(app)
# get the sitemanager
sitemanager = app.getSiteManager()
default = sitemanager['default']
# add an intids
intids = IntIds()
default['intids'] = intids
intids_reg = UtilityRegistration('', IIntIds, intids)
default.registrationManager.addRegistration(intids_reg)
intids_reg.status = ActiveStatus
# add a catalog
catalog = Catalog()
default['catalog'] = catalog
catalog_reg = UtilityRegistration('', ICatalog, catalog)
default.registrationManager.addRegistration(catalog_reg)
catalog_reg.status = ActiveStatus

Thanks!

I bet it's just that you haven't added the key reference package or something like that. Have you included zope.app.keyreference in your ZCML?

Ah well, sorry. Your recipe looks fine. If I were in your shoes my next lazy attempt would be to try committing the transaction with the intids and catalog before adding the indexes. Beyond that I'd have to start digging. Gary ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Ok, I added the transaction... still bangs, the full traceback is at
the end...
Note that if I don't add Indexes, zope3 starts, full of articles. But
when I add the index via TTW and reindex, the articles that I added in
the install.py script aren't indexed (so the IIntIds was not active
during the install.py), BUT if I add further articles TTW, the added are
indexed...
I really donno what/where to dig ;-(

Heh, ok, I'll try just one more one-second diagnosis then. ;-) Are you setting the site? old_site = zope.app.component.hooks.getSite() zope.app.component.hooks.setSite(object) try: # ...add the utilities and indexes in here... finally: zope.app.component.hooks.setSite(old_site) If that doesn't do it, then we'll see if somebody else can suggest Gary ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Group membership based on authenticator
Hello, I've created a pluggable authentication utility instance with a principal folder and a group folder. I've managed to manually map users created in the principal folder to a single group and then grant roles to this group Is it possible to assign membership to the group based only on the principal folder (id or prefix) I've found that I could do: subscriber for=zope.app.authentication.interfaces.IPrincipalCreated handler=.mytest.principalCreated / and then if the prefix of the event.principal.id is what I like then add some group to it, but I don't like the solution Is it possible to do it with the managemente interface? I'm new to zope3 and I have problems finding docs about this. Thanks marko ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
