Re: [Zope3-Users] Utilities naming convention
Hi Frank, I guess I have just seen more Utilities named this way than not - so just confirming things for myself. I am also using zapi all over the place. Perhaps I should stop... I am not seeing deprecation warnings yet. Many thanks.

I didn't know that and I agree with you that it is VERY convenient and usefull, even if it's "just" a set of shortcuts to get access to functions provided elsewhere...

Re: [Zope3-Users] Utilities
Thanks! That's it exactly! I was misunderstanding the concept of a
utility with the name ''.

I've tried in many different instances, and I've ended up reverting as a work around to getAllRegisteredUtilitiesFor(), which works just fine. Once I add the name it works great. What am I missing? Is there some other requirement? My code looks the same as what you've listed. The documentation implies that it does not need a name. Is this a possible Zope 3 version issue or bug? ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

The default name is ''. If you're asking for z.c.getUtility(ISomething), you'll get that -- the nearest utility with a given interface and name ''.

If you want to get all utilities with a given interface, use z.c.getUtilitiesFor(ISomething). You'll get the nearest utility with each given name.

[Zope3-Users] Utilities
What is the best to find the nearest utility without using a name? zapi.getUtility() seems to require a name (though the documentation implies otherwise). zapi.getAllRegisiteredUtilitiesFor() works but it seems to me if you have lots of utilities in other contexts, it would query those as well, and thereby be slow in a large application. I come across this problem frequently and haven't figured out the best way to deal with it. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Simply do not specify "permission" in the adapter directive and use the directive to set your security the same way you do for other components, like content.

[Zope3-Users] Utilities / Adapters security - is access limited to interfaces?
Hi, I have got a question on security: utitlities and adapters only have a simple security attribute (=permission) in the configuration directive, that means, I can't specifiy settings on attributes like with content components. But now what about access, if I have got the needed permission, can I access only the methods, attributes defined in the interface or can I access every attribute of the object? Thanks a lot! ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
