[Zope3-Users] Hi, I'm new here
Hehe, Well, it's ALMOST true, since you guys have done so much amazing work since I last looked in! Anyway, as a newbie, I got some questions: - What docs should I read first? - How do I get Zope 3 up and running on Windows, and what's the best version for me to try? - Where can I find good reference docs? What books should I buy? - Are there any good example apps I can look at so I can build my first app, which is likely to be Swishdot ;-) cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Disappearing dictionary. Upon restart, dictionary resets.
Alec Munro wrote:
class SomeObj:
some_dictionary = PersistentDict({})
ouch, never use mutables for class attributes, for exactly the reasons
you've found.
two points:
1. the dict will get newly created every time this code runs, ie: each
time Zope starts.
2. the object is never seated into the ZODB. It's an attribute of the
class, not any instance of the class, and it's only instances of the
class that are persisted by zodb.
cheers,

[Zope3-Users] sx.translations 1.0 Released!
This package provides components for use with Zope 3 and Zope 2 + Five
that implement both ITranslationDomain and ILanguageAvailability as well
as supporting the recording of untranslated msgids.
This means that, not only do the components support the interface
require to provide messages to Zope 3's i18n framework, they can also be
used to generate a list of available languages using code similar to the
following:
from zope.component import getUtility
from zope.i18n.interfaces import ILanguageAvailability
from zope.i18n.locales import locales, LoadLocaleError
domain = 'myproject'
def getLanguages(self):
options = getUtility(ILanguageAvailability,
domain).getAvailableLanguages()
options.sort()
result = []
for option in options:
lang = option[0]
try:
locale = locales.getLocale(lang)
except LoadLocaleError:
# probably not a real locale
continue
result.append(
{'code':lang,
'name':locale.displayNames.languages[lang],
)
return result
Sample ZCML for configuration could be:
configure xmlns=http://namespaces.zope.org/zope;
xmlns:i18n=http://namespaces.simplistix.co.uk/translations;
!-- make the sx.translations' registerTranslations directive
available --
include package=sx.translations file=meta.zcml /
!-- register our locales using sx.translations --
i18n:registerTranslations locales=../locales
missing=../locales/myproj.pot
encoding=utf-8/
/configure
For more information, please see:
http://www.simplistix.co.uk/software/zope/sx.translations
I'm happy to contribute this code to the Zope 3 core if people can tell
me where and how to do so...
cheers,
Chris

[Zope3-Users] looking for something like getUtilitiesFor...
...but which just gets the names of utilities available for a particular interface. The reason I ask is that getUtilitiesFor returns tuples of name and utility.

If you want that drop-down, consider using UtilityVocabulary from zope.app.component.vocabulary, e.g.: class FooUtilityNames(UtilityVocabulary): interface = IFoo nameOnly = True classProvides(IVocabularyFactory) Register that as a utility: utility component=...FooUtilityNames name=Foo Utilities/ Then you can refer to it from a schema definition (Choice field).

(I'm thinking there must be some kind of drop-down somewhere with an Add list as in Zope 2's ZMI, and that must include the available types of local utility?) Sure. Just use the standard Add menu in Zope 3. Some of the items there are potential local utilities, such as the Catalog, Cookie Client Id Manager, Error Logging Utiltiy, etc. You can add these objects anywhere, though it is recommended to do it within ++etc++site. The thing that makes them available as utilities is the registration. All objects have a Registration tab. Ah, I see, so rather than using ZCML, you use the Registrations tab? (now I'm dying to know if this has been implemented in Zope 2/Five) That said, when you add a local utility in Zope 3, does it automatically register itself by default? It'd be quite annoying to have to: 1. add you thing that uses local utilities 2. oops, actually have to go create the local utility 3. great, now I have to register the damn local utility 4. finally, I can go back and tell my thing to use the new local utility Ideally there'd be some way to do steps 2-4 automatically, but at the very least, having to manually do 3 seems superfluous, although I do like the idea of being able to manually un-register a utility... Also, more theoretically, would you see indexes for a catalog as being local utilities. If not, what would you see them as being? The catalog is the local utility. That's also true, but also not really what I was getting at ;-) It functions as a container for indices. Indeed, and how are these indices managed? For me, an Index is a local (and potentially or maybe even definitely local to only that catalog) utility for ICatalogIndex (or whatever it may be called). For me it'd be nice to register the types of indexes using something like (and this is all pseudo code): utility provides=catalog.interfaces.Index factory=catalog.fieldindex.FieldIndex name=Field Index/ utility provides=catalog.interfaces.Index factory=catalog.textindex.TextIndex name=Text Index/ ...so you then have your list of addable index types.

[Zope3-Users] Adapter registration problem
Hi All,
Why does the following adapter registration not work?
adapter

factory=.factories.Factory
name=something
/
from zope.component import getAdapters
from SomeModule import SomeClass
from interfaces import ISomething
getAdapters((SomeClass('test'),object()),ISomething)
[]

[Zope3-Users] getting post data in a Zope 3 view
Hi All,
I have a view:
from zope.publisher.browser import BrowserView
class Receiver(BrowserView):
def __call__(self):
print self.request.bodyStream.read()
return 'done'
...which I'm trying to test with the following script:
import socket
socket.setdefaulttimeout(5)
from httplib import HTTPConnection
c = HTTPConnection('localhost:8080')
c.request('POST','/@@wasp','foo',{'Content-type':'text/plain',
'Content-length':3})
print c.getresponse().read()
...but the processing seems to hang in bodyStream.read() until the
socket times out on the client side (ie: I get a timeout exception)
at which point the read() returns and shows what I'd expect.
What am I doing wrong?
cheers,
Chris

Yes, ideally there should be some way to hide them on pypi such that setuptools still finds them but that they don't strip up unsuspecting users. Does pypi support this?

That's a very good idea. It should also point people to the current package that does the same thing. E.g. the description of zope.app.form currently says More advanced alternatives are implemented in zope.formlib and z3c.form. near the top. Great, if only I had the access, I'd do it where it was needed... Remove packages on Pypi only (and not on download.zope.org). You'll get shouted at if you remove something from PyPI. Trust me. Which is pathetic. I really don't get this. Yes, theoretically you could leave someone with an old package (well, d'uh, it's the last version of it they're ever going to get so what's the problem) or someone stranded on an newer-according-to-setuptools-but-never-actually-released version, in which case they should be using buildout's prefer-released thingy and pester Phil Eby to make setuptools less braindead here... The response here is find-links option, I think. I heard people complaining a lot about find-links in setup.py files. Hell yes, I didn't even know you could do that. Take 'em out and shoot 'em! find-links in your buildout.cfg might be OK. Indeed, this is where it should belong, or on the easy_install command line if you're not using buildout. cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
