[Zope3-Users] Using RAMCache

[Zope3-Users] formlib handling of adapters
hi i just tried to adapt an object with two similar interfaces: class IBaseAdapter(Interface): content = Text(title=uContent, required=False) class IHomeAdapter(IBaseAdapter): class ILinksAdapter(IBaseAdapter): after that, i created two formlib editform views and registered them on my adapted object. The content property is saved on different annotation keys on the adapted object. The form renders correctly, but the content property is only handled via the ILinksAdapter by formlib. so content is saved always on the same annotation key. if i change my interfaces to class IHomeAdapter(Interface): content = Text(title=uContent, required=False) class ILinksAdapter(Interface): content = Text(title=uContent, required=False) formlib works and uses the two different adapters implementations. looks like a bug, can somebody confirm or comment this? cheers Dominique ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

I'm kind of guessing here.
You say you are:
- querying the catalog
- accessing a random index from the result set
- noticing that this is slow
Does this only happen if the index is very large, e.g. you're retrieving
an element from the end of the result set?
I don't know exactly how the result sets are organized, but this
behaviour would imply that loading a later element triggers something
like loading the earlier elements too. I can't really imagine that.
I think the general problem that this is slow lies in the fact that
randomly selecting elements means
a) you need access to the full list of things
b) applying a sort
Sorting has a complexity of at least O(n log n) which becomes slow
enough for large sets that it's noticable.
BTW: How large is large?
Christian
hi, thanks for the reply, i just managed to improve the performance of my query
significantly:
what i wanted to do was:
- retrieve the len() of the catalog index
- retrieve a list() of the Resultset
- accessing n random results and their objects
to retrieve a random object i did:
query = catalog.apply({'myIndex':(None,None)})
length = len(query)
index_intids = list(query)
intid = all[random.randint(0,len_all-1)]
object = getObject(intid)
which was with 1 items in the index slow (i had to wait 2-3 seconds for a
view to render)
after looking into the field index implementation i changed the above lines to:
length = len(catalog['myIndex']._rev_index)
index_intids = list(catalog['myIndex']._rev_index.keys())
which now works like a charm.
i am not an expert with BTrees so i cant really say what the problem is/was.

[Zope3-Users] problems with catalog: indexing field from an objects adapter
hi, I want to index a field from an object, which works perfectly via Catalog and Field Index. But if my callable field returns a value, which is returned from an adapter of the object, things get complicated for me: i create my object an add it to a container (not via zmi). i do the notify(ObjectCreatedEvent(container[myobjectname]) thing, to let the intid and catalog do their indexing stuff. i look at the Catalog statistics in the zmi, where is see, that one item is indexed. but when i delete the object (i used notifiy(ObjectRemovedEvent(container[myobjectname])), there is still something residing in the index, which causes a KeyError in the intid utility, when it trys to getObject. It seems, that the index is indexing the object and the adapter via the same unique intid, and then deletes only the objects index, and not the adapter? since my adapter is only accessing annotations on the object, i could feed the index directly via the annotation value, but that goes against the use of adapters and the idea, not to change the object implementation. Do you have any idea, what i have to do? Did i forget an event? or something else? thanks cheers Dominique ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

can someone explain me please when to use browser:view and when browser:page?
As far as I understand, the intended use of browser:page is to define
views that are accessible to browsers by using URLs.
The intended use of browser:view is to define helper views that are
accessible to page templates in TALES expressions like
tal:attributes=href context/@@absolute_url.
I might be wrong.
and when would i inherit a View Class from zope.publisher.BrowserView
and when from zope.publisher.BrowserPage, and why do i need them when
i could just inherit from object without any errors?
A browser page must implement IBrowserPublisher if you want it to be
accessible from the outside. BrowserPage does that. The browser:page
also does that, but in a different way. The directive does deep magic
-- it constructs a new class on the fly that implements
IBrowserPublisher and inherits from the view class you've specified. It
can also provide a 'index' attribute and a default implementation of
__call__.
BrowserView only gives you a useful __init__. If you inherit directly
from object, you'll have to define __init__ by yourself.
Looking at the code I see that BrowserView also gives you a __parent__
property that is used by the standard Zope 3 security policy. I do not
think it is all that important, as usually views in Zope3-land are not
security proxied.
Magic is going out of fashion in Zope3-land. In my personal opinion
the best practice for Zope 3 views is to follow this pattern:
class MyView(BrowserPage):
adapts(ISomeContext, IBrowserRequest)
template = ViewPageTemplateFile('...')
def __call__(self):
# do form processing, if any
return self.template()
and then register it with browser:page.
so if i create a class which inherits from BrowserView, and then register it via
zcml as browser:page, it becomes adaptes to IBrowserRequest an turns to a
BrowserPage (via the on-the-fly created class)? so inheriting from BrowserPage
instead from BrowserView would make no sense with my example?

I definitely think Zope 3 can be used to support education. We plan on developing a number of applications in this area. It seems at present that universities are focusing on J2EE and .NET, like most companies. We are also noticing an increasing ability of universities to do their own development. Traditionally many of the software applications that universities use have been purchased. We see an increasing desire to build and customize applications in house. We also find however that in universities the funding and resources required to manage a J2EE or a .NET project are not necessarily there. We believe Zope could fill this role because it is faster to develop in, and python is fairly easy to learn. We find that universities tend to have developers who are a bit less experienced, and this sometimes includes administrators who actually want to do their own development. J2EE and .NET is not easy to pick up for the novice. In this area Zope 3 is particularly challenging in comparison to Zope 2, however there are entry points in Zope 3 with a minimal amount of TTW development. In this sense I personally feel strongly that Zope 3 needs to have a greater emphasis on TTW development so that it can satisfy the needs of the intermediate developers. However I feel that Zope 3 is such a clean and well developed platform that more of these tools will show up. i am definitly with you on your thoughts. i also think that zope, especially zope 3 is a great tool supporting an educational infrastructure. schooltool shows us how to do that. but my question was more about how could someone use Zope 3 *in* his curriculum. my thoughts are like being able to teach topics like software development process, testing strategies (in my opinion software testing is bad supported in education), documenting software (doctests), and all this stuff should have an easy approach (installing, maintaining, developing), both for educators/lectors and students. i think Zope 3 could do a great job there, and i would like to know the community´s optinion about that. * How do you see Component Based Software Engineering (CBSE) related to Zope 3? What are the differences? Is Zope 3 an alternative for other component based frameworks in the industry and why? I'm not sure I understand the question on this one. Zope can be used to provide components in an XML-RPC model, or just about any other; this is the nature of the content view model of Zope. This question has a litle bit historical background. At my university they taught us Component Based Software Engineering (CBSE), and how this will change the way, software will be developed.

somehow add an adapter from IFolder to IAdding or how would I do this?
Tim
As you point out formlib.BaseAddForm calls the add method of the
context:
_finished_add = False
def add(self, object):
ob = self.context.add(object)
self._finished_add = True
return ob
I (also a novice) always use formlib for adding. But I use my own base
adding sub-class of BaseAddForm which has this add method:
def add(self, obj):
try:
ob = self.container.add(obj)
except:
self.container.__setitem__(obj.__name__, obj)
ob = self.container[obj.__name__]
self._finished_add = True
return ob
I almost always use a NameChooser to choose the name for the object. So
I can trust using __name__ as the dict key.
I use self.container here that usually resolves to self.context but on
some occassions the context is not the container I want to be adding to.
Hopes this helps.

yes, thanks, it helped me
but what are we doing wrong here, that the base methods wont work?
why should my container know about the add method?
any help welcome
thanks

Re: [Zope3-Users] no object attributes on IObjectAddedEvent / IObjectCreatedEvent?

Quotation from a posting from Fred Drake about the same problem: Are you using browser:addform? There are four different attributes that can be used to tailor when attributes of the object are set: arguments, keyword_arguments, set_before_add, and set_after_add. Fields that are input but not included in any of these are set after adding the object to it's container.

[Zope3-Users] changing behaviour of PAU SessionCredentialsPlugin
hi i would like to change the behaviour of extractCredentials in the SessionCredentialsPlugin of the PAU. i´m still fighting a bit with the framework: would i use an adapter for this, or subclassing? or would i use the override directive somehow? thank you Dominique ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

My authenticator just passes the principalinfo through. is there any way to get the request object to be accessable in an PAU AuthenticatorPlugin? any other comments on my approach? thanks Dominique ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] security problem setting Annotations with an adapter
hi!
i just added an adapter to my content-class, which gets and sets some
Annotations.
at the moment i do this in the adapters init to be able to set them:
def __init__(self, context):
from zope.security.proxy import removeSecurityProxy
self.context = removeSecurityProxy(context)
otherwise i get an
ForbiddenAttribute: ('__annotations__', my_class object at 0xa6853cec
Error
whats the right way to tell the zope security policy that setting
Annotaions via Adapter is allowed?
thanks in advance!
cheers

[Zope3-Users] how to catalog principal annotations?
hi I have users residing in an external database.I store user data with principal annotations. Now i want to create a view where users with a special annotation are listed. Is it possible to catalog principal annotations and how? Or do i have to create a special Person Class where all principal data is stored on, and connect it somehow to Principals? thanks for your help Dominique ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
