Re: [Zope3-dev] How to provide some default utilities for sub-site

Re[2]: [Zope3-dev] How to provide some default utilities for sub-site
Hello Dominik, I tried it using a subscriber. subscriber handler=.app.App_boot for=zope.app.container.interfaces.IObjectAddedEvent / def App_boot(event): # precondition obj = event.object if not IApplication.providedBy(obj): return ensureUtility(obj, IWorkflowProcessRepository, 'WorkflowProcessRepository', WorkflowProcessRepository, '') ensureUtility(obj, IWorkflowUtility, 'WorkflowUtility', WorkflowUtility, 'wfu') It works, but it adds the utilities to the global site manager :-( If the behavior is OK this way, then why do I have to pass the root_folder? I don't really get it. If I start to go my own way and copy+modify the zope.app.appsetup.bootstrap.py: def getSiteManagerDefault(root_folder): sm = root_folder.getSiteManager() #default = zapi.traverse(folder.getSiteManager(), 'default') #package_name = '/++etc++site/default' #package = traverse(root_folder, package_name) package_name = 'default' package = traverse(sm, package_name) return package then it is working. The 2 utilities land in the local site manager. Friday, November 4, 2005, 12:48:57 PM, you wrote: Hi Adam You need location information (- __parent__) for this setup.

Re: [Zope3-dev] How to provide some default utilities for sub-site
Hi Adam First you have to assert that you object (obj) provides ISite. Then I would use the following attachted helper function `addLocalUtility` to add the your utiltiy. Least, you could use multi-subscriber for events providing IObjectEvent, then you don't have to check for IApplication. Putting all together you get the following (unproved) registration and code: subscriber handler=.app.App_boot for=.IApplication zope.app.container.interfaces.IObjectAddedEvent / def App_boot(obj, event): if not ISite.providedBy(obj): helper.addSiteManager(obj) helper.addLocalUtility(obj, 'wfu', 'WorkflowUtility', WorkflowUtility()) Regards, Dominik Adam Groszer wrote: Hello Dominik, I tried it using a subscriber. subscriber handler=.app.App_boot for=zope.app.container.interfaces.IObjectAddedEvent / def App_boot(event): # precondition obj = event.object if not IApplication.providedBy(obj): return ensureUtility(obj, IWorkflowProcessRepository, 'WorkflowProcessRepository', WorkflowProcessRepository, '') ensureUtility(obj, IWorkflowUtility, 'WorkflowUtility', WorkflowUtility, 'wfu') It works, but it adds the utilities to the global site manager :-( If the behavior is OK this way, then why do I have to pass the root_folder?
