Yes that's the proper way to do compress events: record the stuff to do, and do it at the end of the request. Depending on the stuff to do, it may involve subtleties, for instance if you modify one object then delete it in the same request, you don't want to call your final handler for that object... Thanks for the reply, but I'd like to have a few complements : - I suppose that IEndRequestEvent is sent automatically for every request, so even for consultation requests which doesn't imply any modification. So I suppose that the IEndRequestEvent handler have to be VERY optimised if I don't want it to be too expensive. - what is the best way to keep track of objects having been modified (and which, for example, should be re-indexed) into request annotations. Can I just put an object into an annotation's list (with a kind of "IAnnotations(request)['myKey'].append(context)") ??

Re: [Zope3-Users] request.principal and render/update
no problem anymore, that was a while back. it's been working
correctly for quite some time. if you check the later posts, I did
exactly what you suggest, and use session credentials. it then had an
issue where it assumed that the form always called the fields "login"
and "password" so I overrode that behavior myself. then
AuthenticatedPrincipalFactory doesn't actually adapt a principal back
to the type of principal you originally sent in, but instead sends you
back an IPrincipal, rather than derived version. so I built my own
Authenticated factory as well, to get back a principal with my own,
extra attributes.
as far as the "login/password" fields issue, I'm pretty sure Florian
submitted a fix for that back to svn a while back as well.
Thanks for the answer though!

All this will work, if you use PAU correctly.
I strongly suggest setting up a simple PAU, all with standard components. It
is really not that hard and work beautifully.

I would not define such thing in ZCML, use Python instead:
from zope.schema import vocabulary
vocab = vocabulary.SimpleVocabulary(
vocabulary.SimpleTerm('de', title='German'),
vocabulary.SimpleTerm('en', title='English'),
...
)
Alternatively you could create a vocabulary from a CSV file. Here is some code
I wrote recently:
import csv, os
from zope.schema import vocabulary
def CSVVocabulary(filename):
# Create a prefix
prefix = os.path.split(filename)[-1][:-4]
# Open a file and read the data
f = file(filename)
reader = csv.reader(f, delimiter=";")
# Create the terms and the vocabulary
terms = []
for id, title in reader:
title = unicode(title, 'latin1')
term = vocabulary.SimpleTerm(id, title=_(prefix+'-'+id,default=title))
terms.append(term)
return vocabulary.SimpleVocabulary(terms)
Oh, and if you want to extract those titles for translation, you can use this:
def csv_strings():
"""Extract message strings from CSV data files"""
catalog = {}
datadir = os.path.join(os.path.dirname(__file__), 'data')
for filename in os.listdir(datadir):
if filename.endswith('.csv'):
fullpath = os.path.join(datadir, filename)
vocab = CSVVocabulary(fullpath)
for index, term in enumerate(vocab):
if term.title not in catalog:
catalog[term.title] = []
catalog[term.title].append((fullpath, index+1))
return catalog

All this will work, if you use PAU correctly.
I strongly suggest setting up a simple PAU, all with standard components. It
is really not that hard and work beautifully.

Let's say that the 'mail.html' view provides the HTML for the email body
(whether that's ZPT, Python, or whatever doesn't matter), then you can
simply do:

Right, because you aren't sending the event. Zope does NOT automagically send events when you change an attribute of an object. THis is how you would send an IObjectModifiedEvent manually: >>> from zope.lifecycleevent.interfaces import ObjectModifiedEvent >>> from zope.event import notify >>> notify(ObjectModifiedEvent(myobj)) This is, btw, exactly what the container machinery is doing when you add a child to a container. It's also what the form machinery does when it changes an object as the result of an automated add or edit form.

There are several possible solutions. (a) Local utilities do know about the DB. zapi.getParent(utility) (b) If you rely on the context, then your utility API should incorporate this in the methods, i.e. utility.method(context, ...)

There is absolutely nothing magic about ZPT pages and the Web. We use page templates for all sorts of things including HTML, generic XML and RML. All that th e"view-version" of ZPT does is provide a request and context as top level namespaces. You can write your own page template class that provides other namespaces.

No, your code looks good. I do not see, why Person cannot adapt IPerson; btw,
if an object implements an interface it is always adaptable to this
interface; it simply returns itself.

Please take into account that the next Gecko release (Firefox 3.0) will have agnostic DOM support, with python and friends. And for some markets, having one supported browser is enough. But I guess future zope releases/modules won't make it any more difficult to have "exotic" front-ends, be it ajax, xul, the-ms-alternative-to-xul or xforms.

JS has no good development tools, it is impossible to do decent debugging and testing. (No, I do not consider the browser-based debugger and Selenium acceptable development environments.) Other than that, the way DOM, JS, et al. solve this sort of problem is just horrible. The problem of minimizing network data transfer for a GUI has been solved since over 20 years (X and all its toolkits), but the Web has to reinvent the wheel. I am not going to comment further on the issue.

Another way is writing dynamically generated content components, like LocalFS does in Zope 2. You can also write a custom traverser that dynamically generates callable objects.

In Zope 3 you can simply call utilities/i18nextract.py; it will extract all message strings from Python, ZPT and ZCML files.

How do I manually make objects provide or "unprovide" given interfaces? zope.interface.directlyProvides(obj, ifaces) *overrides all* directly provided interfaces. For simply adding a a directly provided interface without deleting any others use zope.interface.alsoProvides(obj, ifaces). A good usage example is setting the skin on a request.

[Zope3-Users] Re: How to prevent several notifications of events ?
Thierry FLORAC wrote: I've build a simple adapter that modifies context properties through annotations ; everything works fine. In several cases, when some attributes are updated, I do a "notify(ObjectModifiedEvent(self.context))" so that several subscribers are called. My problem is then that if several attributes modifications are done, several "ObjectModifiedEvent" are sent and the same handler is called several times (with the same parameters) ; so is it easily possible to prevent the same event to be called several times for a same context and a same request ? Or should I try to use request annotations and subscribe to IEndRequestEvent (if it's not too late and not too expensive...) ? Yes that's the proper way to do compress events: record the stuff to do, and do it at the end of the request. Depending on the stuff to do, it may involve subtleties, for instance if you modify one object then delete it in the same request, you don't want to call your final handler for that object...
