Now, for some reason, each time Zope was started, it called this, and
whenever I tried to access the some_dictionary propery on any of my

That's the case in zope and python, 'some_dictionary' attribute is mutable.

It seems confusing, you derive from Persistent but only some are accepted.
Does that mean that there's PersistentFloat and PersistentTuple too?
If not, why *only* dicts?
No, this issue applies to mutable attributes..
self.a = 1.1
self.b = (1,2,3)
self.b = (4,5,6)
These will persist as is, because you're rebinding the attribute
(reference) each time.
However, for ...
self.queue[1] = 2
This doesn't rebind self.queue.
So another way you could 'persist' this change is ..
self.queue[1] = 1

Probably best to Make a Site. This will enable you to install utils into each site. This will also enable you set up resources specific to each site.

You can install separate PAU's (Pluggable Auth. Util.) into each site to have different user bases for each site. Alternatively installing a PAU into a top level site enables you to share the user base across sites. I could set up multiple skins, and then change the skin by using apache rewrite rules. But both parts of this are quite hard and complex, and involve restarting both systems. I'd like to be able to set simple things about the appearance TTW. At this point I fear I'm going very wrong, but I'll continue anyway ;-) I'm guessing a little about how you want to set the appearance TTW...

Re: [Zope3-Users] Losely or rather, less loosely coupled objects.
Max M wrote:
When doing sites in Zope 2 I often have the need to couple/contain two
or more fixed objects.
When an object needs to have some specific properites and logic, many
developers choose to subclass an existing object and change that.
Eg. a member folder needs to *allways* have a 'contact_info' object. Eg.
to keep company policy and to ease skinning.
That would typically lead to a new folderish content type with contact
info properties. Which I think is a really bad pattern.
Normally in Zope 2 I just give it a fixed id, and then set the
folder._reserved_names = ('contact_info',) property on the parent folder.
This is like folder.contacts_info = ContactInfo()
But this is a pretty obscure and unknown feature. And site managers
cannot use it.
I have the suspicion that many cases where people are doing Archetype
subclasses in Plone they should really use something like that approach
instead. It would lead to much simpler maintenance in the long run, with
a looser coupling of objects and less repetition of functionality.
Are there any good patterns for this in Zope 3? It would be really nice
to have a standard way of doing it.
Setup the interfaces and class, e.g.
class IContactInfo(Interface):
name=schema.TextLine()
email=schema.TextLine()
# etc.
class ContactInfo(Persistent):
implements(IContactInfo)
name = FieldProperty['IContactInfo']
# etc,
class IContactable(Interface):
Marker interface for objects which can have IContactInfo
Setup an adapter from IContactable to IContactInfo. The ContactInfo
object is stored as an attribute annotation on the IContactable object.
def contactInfoAnnotation(ob):
annotations = IAnnotations(ob)
info = annotations.get('contact_info')
if info is None:
annotations['contact_info'] = info = ContactInfo()
return info
provideAdapter(contactInfoAnnotation, [IContactable], IContactInfo)
Now *any object* which implements IContactable (and
IAttributeAnnotatable) can have ContactInfo. You access the
ContactInfo, e.g.
info = IContactInfo(ob)
info.name, info.email = u'My Name', u'[EMAIL PROTECTED]'
# etc.
For example, you could even make a file object contactable,...
classImplements(File, IAttributeAnnotatable)
classImplements(File, IContactInfo)
ob = File()
contact_info = IContactInfo(ob)
You'd more likely use ZCML class implements directives to mark which
content classes you want to be IContactable.
It would also be nice if those objects did not show up in the navigation
like folder contents. It confuses the users that they cannot delete it.
But rather outside the normal navigation. Like in a portlet or as a
list of actions.
The attribute annotation is not publishable. You expose it explicitly
via views. You can even combine it with the IContactable object in the
view...
class MyView(BrowserView):
__used_for__=IMyObject
def __init__(self, context, request):
super(MyView ...

span tal:replace=view/contact_info/name My Name /span
It's even simpler in a formlib view, because it will automatically adapt
your context attribute similar to the above...
class MyForm(form.DisplayForm):
form_fields=form.Field(
IMyObject, IContactInfo,
)
In Plone that is possible by adding a dot to the id like
'.contact_info', but that is a hack. Also there is no reason to have
those ugly urls.
Any pointers, or am I the only one thinking along those lines?

Re: FW: [Zope3-Users] Generating loginForm with formlib
I want to generate a login form for the PAU session credentials plugin. The
plugin expects a form that have a login and a password field.
I've created a interface:
class ILoginForm(Interface):
For generating the login form.
login = TextLine(title=uUsername,
required=True)
password = Password(title=uPassword,
required=True)
but formlib generates the two fields with name=form.login therefore the
session credentials plugin is able to extract the credentials.
How can I use formlib to generate a login form?
Thanks,
Florian
Hi Florian,
the simplest thing to do (or what i ended up doing) was creating a
credentialsPlugin that provided similar functionality to the standard
session credentials plugin, but where the standard session credentials
plugin's extractCredentials method expects to pull 'login' and
'password' out of request.get(), you just pull
request.get('form.login') or something similar. just return the
credentials dict back out to the principal folder (or whatever
authenticator you're using) authenticateCredentials method with a dict
of the form {'login': credentials.getLogin(), 'password':
credentials.getPassword() } where credentials is a SessionCredentials
object created from your request.get('form.login') and
request.get('form.password').
look at zope.app.authentication.session's design pattern for more.
I reckon the following *should* work, but it doesn't:
from zope.formlib import form
class MyLoginForm(form.Form):
prefix=''
form_fields=form.Fields(ILoginForm)
...
The problem is the generated form names are '.login' and '.password'.
IMHO if there's no form/widget prefix, I can't see why there should be a
leading '.' character.
In the end I patched zope.app.form.Widget.setPrefix() to do what I expected.

The following are normally all equivalent.. http://host/content/++view++edit.html http://host/content/@@edit.html http://host/content/edit.html This presumes that you've configured (normally via zcml) a (Browser)View class named 'edit.html'. If in a particular circumstance, 'content' is a container object which contains an object with the name (id) 'edit.html', then you can explicitly distinguish between this object and the named view 'edit.html' using the 'view' namespace. Look at the inline doc. in zope/traversal/namespace.py for more info about the (very useful) 'namespace' traversal in zope3. Skin variables in URL would be great during development but suggest that the user can make skin selection. I guess the user can make their own skin selection via the url.

Re: [Zope3-Users] question about MailDir folder for queuedDelivery on windows
Hi Shailesh, just make sure there are three subdirectories available in the directory of your mailqueue: cur, tmp, new. This is the common maildir format. see: man 5 maildir *THE* *MAILDIR* *STRUCTURE* A directory in /maildir/ format has three subdirectories, all on the same filesystem: *tmp*, *new*, and *cur*. Each file in *new* is a newly delivered mail message. The modification time of the file is the delivery date of the message. The message is delivered /without/ an extra UUCP- style *From_* line, /without/ any *From* quoting, and /without/ an extra blank line at the end. The message is normally in RFC 822 format, starting with a *Return-Path* line and a *Delivered-To* line, but it could contain arbitrary binary data. It might not even end with a newline. Files in *cur* are just like files in *new*. The big difference is that files in *cur* are no longer new mail: they have been seen by the user's mail-reading program.

Hi Adam,
I'm not exactly sure of your use case, but I've included a widget
implementation (see below) which you may find useful. I've used this
widget for an attribute which is an IImage, e.g.
class IContent(zope.interface.Interface):
image=zope.schema.Object(schema=zope.app.file.interfaces.IImage)
class Content(persistent.Persistent):
# This property makes the image object locatable (see below)
image=LocatableProperty(IContent['image'])
ImageAttributeTraverser=\
z3c.traverser.traverser.SingleAttributeTraverserPlugin('image')
## property.py
from zope import location
from zope.schema.fieldproperty import FieldProperty
def LocatableProperty(field_or_descriptor):
A property which ensures a field instance is locatable.
The argument can be a field or a descriptor for that field. The
zope.fieldproperty.FieldProperty descriptor is used internally
when a field object argument is passed.
A locatable property can be used for traversable attribute objects to
locate them in the referencing object.
Let's create a simple content object with an attribute which is
an image:
from zope import schema
from zope.app.file.interfaces import IImage
image_field=schema.Object(__name__='image', schema=IImage)
class Content(object):
... image=LocatableProperty(image_field)
ob = Content()
ob.image is None
True
Assign an image object which doesn't have location to the attribute:
from zope.app.file import Image
image = Image(data='1234')
image.__parent__
Traceback (most recent call last):
...
AttributeError: 'Image' object has no attribute '__parent__'
ob.image = image
When we now access the attribute object, it we find that is has
been wrapped inside a location proxy object:
ob.image.__parent__ is ob
True
ob.image.__name__
'image'
ob.image.data
'1234'
try:
field_or_descriptor.__get__
field_or_descriptor.__set__
return Locatable(field_or_descriptor)
except AttributeError:
return Locatable(FieldProperty(field_or_descriptor))
class Locatable(object):
Wrap a FieldProperty descriptor to make it's field locatable.
def __init__(self, descriptor):
self.descriptor = descriptor
self.name = self.descriptor._FieldProperty__name
def __get__(self, inst, cls):
ob = self.descriptor.__get__(inst, cls)
if ob is not None:
if location.interfaces.ILocation(ob, None) is None:
ob = location.LocationProxy(ob, inst, self.name)
return ob
def __set__(self, inst, ob):
self.descriptor.__set__(inst, ob)

Re: [Zope3-Users] Registered utility is never found
Hi Frank,
is your InitIndicator-instance implementing the
IInitIndicatorFB-interface. This is absolutely necessary
for providing it as an utility. There's an easy test for this:
from zope.interface.verify import verifyObject
ii = InitIndicator()
verifyObject(IInitIndicatorFB, ii)
True
I usually put this in the docstring of classes I want to use as
utilities. Just to make sure :-).

the site root folder itself lists the registration in site.registrations lists
the
registration as expected.
Registering via browser doesn't work either :-( .

Re: [Zope3-Users] Re: NotYet error when creating content during container creation
Yes, this is what I'd recommend. A handler for an ObjectAddedEvent will
always see the object already as part of the object hierarchy (which is,
after all, what ObjectAddedEvent is about).
I found myself doing this quite often.
I use a decorator to make the code read nicer..

@callafteradd
def setup(self)
self['subobject'] = SomeObject()
self['subobject2'] = AnotherObject()

def callafteradd(method):
Decorator which invokes a method after an instance
has been added to a container.

if caller_locals.get('__callafteradd__') is None:

caller_locals['__callafteradd__'] += (method,)

Hi
I've got a problem with menus. I'd like to define a global menu, and then add
some options to it depending on actual context (view registered for specific
interface). The problem is that when I define global menu element link like:
action=/index.html it generates url which omits my folder structure which
shold be: root/my_site/index.html and creates: root/index.html. On the other
side when i use: action=index.html the url which is created is always
relative. I'd like to be able to define my_site (which is in fact a Site
object) to be root for actions.
What is the correct solution for that? Should I edit global urls before
displaying them (add my_site part)? Look at third code snippet below - it
generates urls so I can easly change some strings. Is this a proper solution?
My code:
Menu definition:
browser:menu
id=monitor_menu
title=menu description here

Global menu action (snippet from worldcookery.com code):
browser:menuItem
for=*
menu=monitor_menu
title=Start
action=/index.html

I'd like to know how to arrange (e.g. group) widgets in a form with

One way would be to create a custom template file, where each widget is

I've often done this and it doesn't seem like too much work. But I don't
dispute your evaluation.
Well, when looking at the template, I roughly have to write this for every
widget:
div class=label
label for=field.name title=The widget's hint

I started a form layout add-on for formlib, see snippet below..
It's a very rudimentary first cut, and only provides a grid (table)

[Zope3-Users] Problem running examples from Zope3 book Weiterhausen
Hi, I'm a newbie to Zope and taking my first steps into this wonderful world by going through the book 'Web Component Development with Zope 3' from Philipp von Weitershausen. Up to page 94 I have had little difficulties reproducing the examples. I'm using the downloaded example code as described in the book. I'm running Zope 3.2 on a Windows 2000 machine with Python 2.4 installed. My browser is Mozilla Firefox 1.5.0.1. Real troubles start with the code in paragraph 7.4 which adds a customized list input widget. The browser/widget.pt and browser/sequence.js files run fine when directly invoked from the browser. But when I run it from the Zope instance with the added browser/widget.py and changed browser/configure.zcml it doesn't work. Here is what happens: I copied the downloaded code from the book to C:\Python24\Zope3InstanceWeitershausen\lib\python (this was successful for the previous examples) I start Zope by: C:\Python24\Zope3InstanceWeitershausen\.\bin\runzope I've made sure that C:\Python24\Zope3InstanceWeitershausen\lib\python is in my PYTHONPATH I've deleted C:\Python24\Zope3InstanceWeitershausen\var\Data.fs manually to get rid off previous experiments I start my browser and log on using http://localhost:8080/manage It al looks fine and I have the Add - Recipe button I click on Add Recipe and the screen goes blank displaying: Going back and looking up the error log I see: Traceback (innermost last): Module zope.publisher.publish, line 138, in publish result = publication.callObject(request, object) Module zope.app.publication.zopepublication, line 161, in callObject return mapply(ob, request.getPositionalArguments(), request) Module zope.publisher.publish, line 113, in mapply return debug_call(object, args) - __traceback_info__: bound method +.action of zope.app.publisher.browser.viewmeta.+ object at 0x02E0EAB0 Module zope.publisher.publish, line 119, in debug_call return object(*args) Module zope.app.container.browser.adding, line 128, in action name=view_name) is not None: Module zope.component, line 165, in queryMultiAdapter return sitemanager.queryMultiAdapter(objects, interface, name, default) Module zope.component.site, line 75, in queryMultiAdapter default) Module zope.interface.adapter, line 475, in queryMultiAdapter return factory(*objects) Module zope.app.form.browser.editview, line 64, in __init__ self._setUpWidgets() Module zope.app.form.browser.add, line 49, in _setUpWidgets setUpWidgets(self, self.schema, IInputWidget, names=self.fieldNames) Module zope.app.form.utility, line 153, in setUpWidgets context=context) Module zope.app.form.utility, line 101, in setUpWidget widget = widget(field.bind(context), view.request) Module zope.app.form, line 120, in __call__ return self._create(args) Module zope.app.form, line 102, in _create instance = self._widget_factory(*args)TypeError: __init__() takes exactly 3 arguments (4 given) As a newbie this is all too much for me. I've visited the books' website but there are no clues from the errata. I've tried to look into release notes to see if something changed in Zope 3.2 that explains it but no luck. Can anyone help me out? I've tried running other examples form the book past chapter 7 but they also fail probably to my same mistakes.

[Zope3-Users] registerHandler question/problem
Hi this is my first post to this group. I hope someone can help me. I have the following problem using Zope 3.4: I have created a simple handler using the @adapter decorator and register it in the local site manager. The handler works fine but the ZMI tab showing the sites' registrations crashes with a ComponentLookupError in HandlerRegistration. The message comes from @@registrations.html and it appears that my handler should have zope.app.component.browser.registration.ISiteRegistrationDisplay implemented. This however, requires a class. So I created a class with a __call__ method, but I cannot even get it to work as a global handler... :-( Can anyone explain how to register a handler in the local sitemanager without crashing the ZMI registrations tab? Even a simple handler in a class using implements/adapts with ZCML configuration in stead of the usual @adapter decorator approach would be very helpful. Thanks, Tom ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
