|---|---|---|
| timte | from zope import component | 00:38 |
| timte | component.provideAdapter(...) | 00:38 |
| timte | or | 00:38 |
| timte | from zope.component import provideAdapter(...) | 00:38 |
| timte | provideAdapter(...) | 00:38 |
| timte | What's preferred? | 00:38 |

| *** vlado has quit IRC | 12:35 | |
| timte | If I add and register a utility using zmi, shouldn't I be able to queryUtility(IMyInterface, 'utilityname') ? | 12:44 |
| timte | it returns None | 12:44 |
| *** ktwilight has quit IRC | 12:49 | |
| *** flox has quit IRC | 13:01 | |
| philiKON | timte, sure, but only in that site | 13:02 |
| timte | I use the default one | 13:02 |
| philiKON | oh, and 'utilityname' has to be the name with which you registered the utility | 13:02 |
| timte | yes it is | 13:03 |
| philiKON | not the URL name of the object | 13:03 |
| philiKON | harobed, yes, what is it | 13:03 |
| timte | zmi registration says "events.interfaces.IEventUtility utility named 'eventtool'" | 13:04 |
| timte | queryUtility(IEventUtility, 'eventtool') returns None though | 13:04 |
| philiKON | where do you do the queryUtility call? | 13:04 |
| timte | does queryUtility know which site to look in? | 13:04 |
| timte | in a zopectl debug session | 13:05 |
| philiKON | it knows after traversal | 13:05 |
| philiKON | well, that's your problem | 13:05 |
| philiKON | you haven't traversed to anything yet | 13:05 |
| philiKON | how would it know where to look | 13:05 |
| philiKON | you need to imitate traversal to the site | 13:05 |
| timte | that's what the magic of zope should solve ;) | 13:05 |
| philiKON | there's no magic | 13:05 |
| philiKON | from zope.app.component.site import setSite | 13:05 |
| philiKON | setSite(root) | 13:06 |
| timte | cool, it works | 13:07 |
| timte | thanks | 13:08 |
| timte | Does it make sense to store events in an event utility? To me it doesn't make sense to store them in a certain folder, I think they should be placeless and then I think of utiliities. | 13:09 |
| *** baijum has joined #zope3-dev | 13:11 | |
| philiKON | what kind of events? | 13:12 |
| timte | content types with start, end and location | 13:15 |
| *** jukart has joined #zope3-dev | 13:21 | |
| philiKON | timte, doesn't feel like a utility to me | 13:28 |
| philiKON | but it's your call :) | 13:28 |
| timte | certainly :) | 13:32 |
| timte | but I don't know what alternatives there are | 13:32 |
| harobed | philiKON: you are see that http://mail.zope.org/pipermail/zope3-users/2006-September/004646.html | 13:33 |
| philiKON | harobed, read the docs! | 13:33 |
| philiKON | you're asking many many questions that are answered by the docs | 13:34 |
| harobed | ok, I read | 13:34 |
| *** zagy has joined #zope3-dev | 13:35 | |
| philiKON | harobed, please don't ask further questions till you have read the docs | 13:35 |
| timte | what are the alternatives? Is there any other alternative than storing them in a certain event-folder? | 13:36 |
| philiKON | store them where you want | 13:36 |
| philiKON | it all depends on your use case | 13:36 |
| timte | it's not a folder users are meant to visit | 13:37 |
| harobed | philiKON: I read zope/app/keyreference/persistent.txt but I don't solve my issue | 13:37 |
| harobed | documentation is very scatter | 13:38 |
| philiKON | persistent.txt explain NotYet | 13:38 |
| harobed | yes, I know, but in my last test I use ztapi.provideAdapter(IPersistent, IConnection, connectionOfPersistent) | 13:39 |
| harobed | and it doesn't work | 13:39 |
| philiKON | you have to save your object in the zodb first (e.g. transaction.commit() or transaction.savepoint()), or have its __parent__ be a saved object | 13:39 |
| philiKON | harobed, don't use ztapi | 13:39 |
| philiKON | harobed, documentation is not scattered, it's collectedin the apidoc book | 13:41 |
| harobed | ok, I'm going study | 13:42 |
| *** ofer has joined #zope3-dev | 13:43 | |
| harobed | I think than I don't understand the base of Zope 3 | 13:44 |
| harobed | I'm going to reread persistent layer | 13:44 |

| timte | what is this a symtom of? | 20:03 |
| timte | TypeError: ('object.__new__(Event) is not safe, use persistent.Persistent.__new__()', <function _reconstructor at 0xb7e0d064>, (<class 'events.event.Event'>, <type 'object'>, None)) | 20:03 |
| benji | timte: it doesn't appear that persistent objects are meant to be used that way | 20:06 |
| timte | my Event class inherited from object before, but I changed to Persistent | 20:07 |
| radix | did you fix all the upcalls? | 20:07 |
| timte | what? | 20:08 |
| MiUlEr | hi | 20:08 |
| radix | timte: upcalling is when you call a superclass' method from an overridden method | 20:08 |
| timte | radix: ah, I have an init method without an upcall, maybe that's what | 20:09 |
| timte | what's wrong | 20:09 |
| *** regebro has quit IRC | 20:13 | |
| timte | It was caused by me changing the superclass method. It didn't like that. | 20:15 |
| timte | Do you have to write migration scripts if you choose a new superclass to inherit from? | 20:16 |
| d2m | i get this when running from a custom site.conf "ConfigurationError: ('Invalid value for', 'menu', "ImportError: Couldn't import zmi_views, No module named zmi_views")" -- any hints what to include to make that go away ? | 20:19 |
| *** jukart has quit IRC | 20:20 | |
| d2m | the error is triggered from a <page ... menu="zmi_views"> directive | 20:21 |
| timte | what if you specify browser:page? | 20:22 |
| d2m | i already did <include package="zope.app.publisher.browser" file="meta.zcml" />, but "zmi_views" is defined somewhere a place i could not find so far | 20:24 |
| radix | timte: generally, you need to migrate data when assumptions about data change. it's not unlikely at all that changing which superclass to use for a class will change assumptions about data. | 20:24 |
| timte | bah, I renamed my utility to IEventUtility, now when I want to add an Event it thinks I want to add EventUtility | 20:24 |
| timte | radix: I have no idea how to write such migration scripts though :/ | 20:26 |
| *** flox has joined #zope3-dev | 20:26 | |
| timte | d2m: what happens if you add the browser namespace in the configure tag? | 20:31 |
| *** harobed has quit IRC | 20:32 | |
| d2m | timte: its already there, as default namespace of the included config file | 20:34 |
| d2m | i think there is a machinery setting up zmi_views (and zmi_actions) that is not done through configuration | 20:35 |
| philiKON | d2m, is this in five? | 20:35 |
| d2m | no, i 'simply' try to bootstrap a site.conf in order to a songle package (apidocs) running | 20:36 |
| d2m | so i created an site.conf, only included the "zopeskel/etc/package-includes/apidoc-*.zcml" files and now try to include all dependencies to get the config run | 20:38 |
| philiKON | right. you need to define the zmi_views menu | 20:38 |
| philiKON | <browser:menu name="zmi_views" /> or something like that | 20:39 |
| timte | "This object isn't yet registered." | 20:39 |
| timte | What does this mean? | 20:39 |
| philiKON | it's not registered as a local utility yet | 20:42 |
| d2m | philiKON: cool, <browser:menu id="zmi_views" /> did it so far, thanks | 20:42 |
| philiKON | np | 20:42 |
| *** regebro has joined #zope3-dev | 20:42 | |
| timte | but it's a content type I'm trying to add, not a utility | 20:43 |
| philiKON | then don't register it :) | 20:43 |
| timte | but it suggests me to, that's confusing :) | 20:43 |
| philiKON | then disable it | 20:44 |
| philiKON | you can register it any object | 20:44 |
| philiKON | so that's why the view is there for all objects | 20:44 |
| philiKON | just like you could use <utility /> with any object | 20:45 |
| timte | ok, so if I don't have a "view" view, then I get the registration view | 20:45 |
| timte | can the registration view be disable for all objects that are not utilities? | 20:46 |
| philiKON | how would you know it's a utility? | 20:46 |
| timte | utilities are specified in zcml, no? | 20:47 |
| philiKON | local utilities aren't | 20:47 |
| philiKON | not necessarily at least | 20:47 |
| timte | oh | 20:48 |
| philiKON | that's what the Registration tab is for, dude | 20:48 |
| philiKON | registering an object as a local utility | 20:48 |
| timte | I see | 20:49 |
| regebro | OK, having the local registration view end up as default may not be very intuitive. Maybe we should fix that. | 20:56 |
| regebro | Like when you get the undo-screen in the ZMI because you haven't defined anything else. :) | 20:56 |
