Re: [Zope3-Users] So, there is going to be no Zope4... how to handle maintenance a couple of years from now?
Hi, I think ZCA doesn't do "so much more" than implement a few object design patterns and provide a very flexible components registry framework. I'm working mainly on developing new framework-like packages and I just can't work without it except by re-inventing it! Many users blame ZCML just because it's XML ! But it's just configuration, and separating configuration from Python code is one of the greatest benefits of ZCML, mainly while working on huge projects. The XML format is just a detail and is probably not so worse than many INI-like or text based configuration format; and at least it's a de-facto standard.

If you are considering a complete re-development, maybe you should have a look at Pyramid. It allows you to reuse a lot of Zope related technologies, including ZODB, traversing and even ZCA ! ;-) I use and develop ZTFY which is based on Bluebream (with updated packages based on ZTK) and which is used in many of my own projects with great success, but which is probably condamned to death in a relatively near future...

Re: [Zope3-Users] Installation problems with ztfy.webapp on fresh baked gentoo!
Hi,
I've tried to create a new ztfy.webapp site from a fresh virtual
environment and didn't had any "real" problem.
I've tried using several environments (based on setuptools or
distribute) always with good results.
The only thing I had to do was to upgrade my setuptools package
("easy_install -U setuptools" or "pip install -U setuptools").
I work with an up-to-date Debian "sid" operating system (unstable,
amd64).
Regards,
Thierry

Using Zope 2 for several years, I switched to Zope 3.3 probably five years ago and our latest developments since two years are based on ZTK and ZopeApp. We are really very happy with these! Having small teams of developers, mainly coming from the Java world, training them for recent environments was more "natural" and easier to them than it was for Zope 2. The main problem with these releases is that BlueBream "as is" is a dead project; I only used it as a base to create my new development environments based on recent releases of ZTK and ZopeApp packages. These ZTK and ZopeApp packages are still maintained (last release was in May, 2012) but don't seems to evolve much actually (even if development work seems to be visible in Launchpad). Development community on these packages don't seems to be very active or is, at least, hard to find! Same for Grok, for which the last release was 18 months ago. Excluding Django, Pyramid seems to be the most active project actually among those you mentioned. And it can include many "old" Zope concepts (ZODB, traversing...). But I didn't had any time to test it until now... Best regards, Thierry ___ Zope3-users mailing list Zope3-users@zope.org https://mail.zope.org/mailman/listinfo/zope3-users

That shouldn't be a problem, it's not different when you use a "basic" folder-like container which, internally, stores sub-objects in an internal b-tree container ; the only difference here is that you own two internal containment attributes. > 2.

If the targetted object is persistent (and so a subclass of "Persistent" class), it should be stored only once in the database (just try to alter properties of an object and check if the other one is also modified or not to check !) Another way I commonly use to store references is to store only an IIntIds utility reference, which is an integer ; the benefit of this is that this value can easilly be indexed.

Hi,
You probably have a mechanize package (0.1.11) in your default Python
install and another one (0.2.0) in your Buildout eggs directory.
Maybe you should try to create an isolated environment (without site
packages) using Virtualenv ??

[Zope3-Users] reStructuredText sections question
Hi,
Sorry for cross-posting but I don't know where to ask for this little
question...
I use reST to produce contents which can be :
- generated as standalone HTML pages
- included into an existing CMS (via Zope3)
While generating HTML from my CMS, how can I produce sections headers
starting, for example, as "H3" headers instead of "H1" ?
I've seen in Zope3 reST renderer this kind of code :
def render(self):
settings_overrides = {
'halt_level': 6,
'input_encoding': 'unicode',
'output_encoding': 'unicode',
'initial_header_level': 3
}
writer = Writer()
writer.translator_class = ZopeTranslator
html = docutils.core.publish_string(
self.context,
writer=writer,
settings_overrides=settings_overrides,
)
return html
I suppose that "initial_header_level=3" allows to handle my use case,
but apparently it doesn't work...
Any hint ?
I'm currently using Zope-3.4 KGS, with zope.app.renderer-3.4.0 and
docutils-0.4...
Thanks,
Thierry

[Zope3-Users] TextIndexNG question...
Hi, I'm currently using TextIndexNG (release 3.2, I think...) to index documents in a Zope3 application. Indexed documents are multi-linguals ; I've created one index for each field and each language, because all fields are not indexed in the same way (for example, I use stopwords on documents contents but not on titles). Everything is **nearly** fine, except for one thing : in french, I have to index a word like (for example) " l'eau " ; the important word is "eau" here so, so while searching on title I would like to get a result while entering query "eau" as well as " l'eau ". Actually, none of them is working ! I tried to debug a bit, and noticed (if I'm not wrong), that : - it's the word " leau " which is computed for indexing - but the query " l'eau " is not modified while searching. I suppose that all this is a splitter/stopwords problem, but I can't manage to make this work correctly so any help would be greatly appreciated.

To run code automatically at application startup, I think that you
should have a look at the IDatabaseOpenedWithRootEvent (defined in
zope.app.appsetup.interfaces).
I use this event to check a set of persistent database utilities at
application startup, and it works fine.

[Zope3-Users] TextIndexNG ranking questions
Hi, I'm currently using TextIndexNG-3.2.0 as well as other zc.catalog indexes in a Zope-3.3.1 application. Indexing several fields as well as external files seems OK, but now I'm facing a few interrogations about searching and ranking : 1. I've created TXNG indexes with a "term_frequencies" storage and ranking enabled => OK 2. I'm now using "hurry.query" package to run queries on a set of catalogs ; it's generally OK but my main question are : - how can I use TXNG ranking feature when running a single query against several indexes (actually I have to run queries against several ValueIndex indexes, matching workflow status and publication date, and one or two TextIndexNG indexes -- one for title and another one for content) ? How can I be sure that my results order is matching ranking ?? - does a ranking query generate a numeric value which could be used to display to users the relevance of found results ?

I'm replying to my own message after a short discussion on IRC with Stephan Richter, for anybody which would be interested in the answer... The problem is coming from the ITestSkin interface, which was inheriting from IDivFormLayer : actually, IDivFormLayer benefit is to provide a ready to use div-based form layout ; so if your goal (like for me in this example) is just to override this layout template, inheriting from IDivFormLayer doesn't make any sense.

[Zope3-Users] Problem with z3c.form / z3c.formui packages
Hi, I'm trying to use a few z3c.* packages to build a little test application : z3c.form, z3c.formui, z3c.layout, z3c.pagelet... What I've done until now is : - create a custom layer : class ITestLayer(z3c.form.interfaces.IFormLayer, z3c.layer.pagelet.IPageletBrowserLayer) - create a custom skin based on this layer : class ITestSkin(z3c.formui.interfaces.IDivFormLayer, ITestLayer) - create a pagelet based layout for my skin (via z3c.layout) - create an add form, a display form and an edit form for my custom content : class TestAddForm(z3c.formui.form.AddForm) class TestDisplayForm(z3c.formui.form.DisplayForm) class TestEditForm(z3c.formui.form.EditForm) - declare these forms as pagelets (via z3c.pagelet) Until now, everything is OK : I've created a set of custom widgets that I can display without any problem in the different modes, and these forms work perfectly. My problem is that I would like to modify the default form template, actually provided by z3c.formui template 'div-form.pt' ; so I've created a new template, but I can't use it : I've tried to register it via several ZCML directives (z3c.template...), but none of them is OK and my custom template is never used ! So I just suppose that it's my ZCML directive which is bad, that I missed a set of declarations (I didn't declare any macro, for example), or just that the interface for which the template is registered is not the good one...

[Zope3-Users] Dynamic interfaces ?
Hi, I'm looking for a way to handle what I've called "dynamic interfaces". My problem is quite simple : I have an application where an administrator can define "content types" ; for each content type, a set of common predefined attributes are used, but the administrator can define for each content type a set of custom attributes, each attribute being defined by a name, a datatype (text, textline, date, boolean...) and eventually a list of references values (for choices) ; definition of these custom attributes is persistent and stored in the ZODB. When creating data, contributor can select the data type, according to which the matching set of attributes will be available in forms. The main point is probably that I'd like to use z3c.form package "as usual", and so integrate this attributes management into Zope3 interfaces machinery... ; I suppose I should need a king of "interface factory", but couldn't find any link about that.

What am I doing wrong? (See attached error.txt for full error.) Hi, As explained into error message, you can't store security proxied objects into ZODB : you have to remove proxy before they can be stored. What I generally do is just something like this : ... from zope.security.proxy import removeSecurityProxy class Driver(Contained): implements(IDriver,ILimoserviceContained) _car = None def _getCar(self): return self._car def _setCar(self, value): self._car = removeSecurityProxy(value) car = property(_getCar,_setCar) ... Like that, any way the car property is modified, it's automatically unproxied and can be stored safely.

Hi, Maybe I'm wrong, but I thing that '__del__' destructor is not called when an object is removed from it's container, but when it's references count in Python interpretor is decremented to 0. For your use case, the only thing you should do is just to implement a subscriber to IObjectRemovedEvent (defined into zope.app.container.interfaces) which is automatically fired by all "standard" Zope3 containers.

[Zope3-Users] Installing Twisted with ZopeProject
Hi, Until now, I was using Zope (3.3) installed from source (on Linux) without problem. Actually, I'm trying to discover ZopeProject and other eggs based distributed packages, which seems to become the default (only ?) distribution mode for future releases of Zope3. My problem is simple : I'm currently using the "scheduler" package, which is using the Twisted framework to handle tasks scheduling. But the Twisted package is not provided anymore via ZopeProject as it was with previous Zope3 "big package". So : - I've installed VirtualEnv - I've installed ZopeProject into it, created and launched a new application and everything was OK - I've tried to add "twisted" in setup.py file generated by ZopeProject ; but it seems that the package can't be installed via SetupTools. Should I install it by hand, use "twisted" package provided by Zope3 or can I use python-twisted packages provided by Debian ? - when Twisted is installed, how can I setup my ZopeProject application so that Twisted web server is used instead of default ZDaemon ? For my own information, could anyone also tell me what are the benefits of the different web servers that can be used with Zope3 (Twisted, ZDaemon...) ??

This output is just the same as what I can read when starting Zope.
Also, as you can see, I'm using a ZEO client storage and Twisted web
server ; I only found "logreopen" and "SIGUSR2" references in ZDaemon
source code, and I thought that default server for Zope-3.3.1 was
Twisted...

[Zope3-Users] View or content provider
Hi, I need very basic content providers to generate HTML contents from a set of classes, inside pages templates. Is there a huge difference between using views (and "context/@@viewname" syntax) and using content providers (with "provider:providername" syntax), mainly in terms of performances, CPU usage and/or memory usage ?? Thanks for any advise for this simple "problem", as both methods work perfectly...

First of all, I thing that you can implement a RAM cache manager as a
utility into your site, and then just get to it via
zapi.queryUtility('IRAMCache').
But I didn't use RAM cache until now so I'm not sure if everything is OK
with them...

I speak from personal experience. Whoops ! I'm really sorry but I think I made a stupid mistake in my zapi.getMultiAdapter() call, because I used a "custom" request as parameter instead of the initial request I received in my JSON MethodPublisher subclass ; that's probably because of several tests I made to get things working as I need... :-( Really sorry again, but now it works perfectly...

(provided you first call the update method) In fact it's a little bit more complicated... What I have at first is a BrowserPage view, which is generally called from a page template with "context/@@viewname" syntax, without any problem. But I need also to be able to get the same view output from a JSON call, so that I can update a little bit of HTML code dynamically.

[Zope3-Users] Small skinning question...
Hi, I'm building a new application with Zope3. In this application, I can use several skins : - for all "back-office" and management pages, a single skin is used ; it's defined via an Apache rewrite rule on a specific virtual host - for front-office pages, the applied skin can be chosen by each "subsite" administrator between a set of skins made available to him. My idea is to use the "IBeforeTraverseEvent" on the "site" container, and to apply the selected skin when I'm on a front-office page. So my question is simple : can I know easilly (without hardcoding virtual hosts, in fact) if I'm on a back-office page or not and, in fact, if a specific skin has already been applied ?

[Zope3-Users] Formlib and custom validation constraints
Hi, I'm having a few problem(s) with Zope3's formlib package.

The interface field is actually defined as "required=False", which is the more current case ; when field is required, setting "self.widgets['myfield']" is enough in "setUpWidgets" to display the field as mandatory, but not to let this constraint to be checked.

Hi,
I've written my own adapter to get the list of roles granted or denied
for a given principal, and the list of principals granted or denied for
a given role, always in the context of the adapted object ; you'll find
the source code into joined files, just having to configure it :
I'm far from sure if this is the best approach, but at list it works for
my own needs in the context of zope.app.securitypolicy.
Writing the same adapter to get the list of permissions (by iterating
throught the list of granted or denied roles and using the
IRolePermissionManager interface) shouldn't be too difficult...
Hope this will help you,

Absolutely ! My difficulty is due to the fact that this duplication is done in a workflow context, which isn't aware of the different interfaces supported by the duplicated objects ; sometimes, it's a whole container which can be duplicated in a single operation, and so it's whole content have to be duplicated and indexed correctly... But workflow classes can't notify events for classes it's not directly aware of. Right ?

Hi, Thanks for this link ; in fact I already downloaded "zc.copy" but just forgot to take a look at it... In fact, after looking at "zc.copy" package, I finally used the "original" zope.copypastemove package function to duplicate my content because it better feets my needs, without duplicating a set of informations as zc.copy does but just keeping a link on them. The last problem I still have is that some of the informations stored into object's annotations have to be indexed into a set of catalogs. While these informations are indexed correctly when annotations are created "by hand" in the "normal" way, it's not the case when content is duplicated "in a whole". Any idea ? Should I iterate over object annotations and check for ones that should contain indexable content ?

[Zope3-Users] Content cloning ?
Hi, In an application I'm currently building with Zope3, I need to be able to "clone" several kinds of content data. While cloning a simple content class is quite simple, I don't know exactly how to clone data provided through adapters, which may store these data throught annotations. What I was thinking about was something like : - create a new interface "IClonable", with a single "clone" method - make my specific content interfaces, eventually provided throught adapters, extend IClonable - get a list of interfaces provided by my content class, directly or throught adapters, which extend IClonable, and call their "clone" method when cloning is required. So, actually, my main problem is : - how can I get the list of interfaces provided by a given class, directly of throught adapters ? - is this conception method the best one in Python/Zope3 to clone data ?? Thanks for any help or advise...

Hi, I had a several problem to handle regular "alerts" which I solved in this way : - scheduling in done via the "schedule" package, available from Zope3 SVN ; I created an "AlertManager" utility which is a subclass of scheduler.CronTask (because my alerts are launched at fixed time, but you can use other classes) - objects which can raise alerts are registered with a specific interface IAlert - when the AlertManager is launched, it opens a new connection (via ZEO.ClientStorage), search for registered components (via zapi.getAllUtilitiesRegisteredFor(IAlert)) and call one of the interface's methods which may raise the alert. In my use case an email is sent, but it could be any kind of alert that Python can handle. I'm far to know if this is the best approach, but at least it works quite efficiently...

[Zope3-Users] Database conflicts errors ?
Hi, I'm currently writing an image management adapter for Zope3. It's goal is just to create and store thumbnails "on the fly" when an image is requested with an additional specific traversal name (for example, "myimage/thumbnail" will create a thumbnail of a given predefined size, while "myimage/200x200" will create a copy of the original image reduced to 200 pixels). These thumbnails are stored in the original image annotations. Everything seems to work fine, except for a little thing : I've created a specific widget so that, when an image is uploaded, a thumbnail of the new uploaded image is immediately displayed next to the "data" field upload button. But when the form is displayed, a "DatabaseConflictError" is visible into Zope's log, even if everything seems to work correctly from a browser's point of view. I'm not completely sure to understand what DatabaseConflictErrors are, so any explanation about this kind of problem would be greet. I'll just add for your information that I'm using ZEO...

Many thanks : it seems to work perfectly ! The main solution was to know the "hooks.setSite()" method.

[Zope3-Users] Problem with ZODB...
Hi,
I know this message is not closely related to Zope3, but I hope someone
could help me.
I have an application with :
- a local ZODB
- a remote ZODB accessed throught ZEO and a ClientStorage to read or
duplicate a few informations when required.
But if I do, for example :
def copyToRemote(source):
storage = ClientStorage((hostname, port))
db = DB(storage)
tm = transaction.manager
connection = db.open(transaction_manager=tm)
root = connection.root()
app = root['Application']
parent = traversing.api.getParent(source)
name = traversing.api.getName(source)
remoteParent = traversing.api.traverse(app, name)
remoteObject = Folder()
remoteParent[name] = remoteObject
When transaction is committed, I receive an InvalidObjectReference for
'remoteObject' ("Attempt to store an object from a foreign database
connection") which I don't understand, as remoteObject is a new object
which is not loaded from the local ZODB...
I've tried to find a few documentation about multi-databases
applications, but can't find how to manage this problem.
Of course, any help would be really appreciated...
Thanks in advance,
Thierry Florac

[Zope3-Users] Synchronizing with a remote host
Hi, I need a few advises. I'm building a new Zope3 site, including : - a 'back-office' server, containing all internal data handled by contributors and administrators, including drafts, versioning, workflows, publication, archiving... - a 'front-office' server, containing a selection of published data available to the outside. I need to be able to synchronize data from back-office to front-office, so that : - all the maintenance is made on the back-office server - any published data is made available to the front-office - any retired data is deleted from the front-office immediately. To handle such a task, I was thinking about using : - a ZEO server instance on the front-office server, - and a ZEO ClientStorage on the back-office to handle replication of data to the front-office. Of course, I'm far from sure if this is the best way to handle my problem. There may be several approachs (using XML-RPC ?) and as I'm not a great ZODB or ZEO specialist, any advise would be greatly welcome.

Oops, Sorry !!
The error was a simple syntax error : correct method name is
"getManualTransitionIds()", without the "s".
But as said in a previous post, the ForbiddenAttribute exception is
strange in such a case...

[Zope3-Users] ForbiddenAttribute problem with viewlet manager and hurry.workflow
Hi,
I'm trying to use the "hurry.workflow" package (loaded from CVS) to
handle a simple workflow.
I've created a ViewletManager to display available transitions, but a
ForbiddenAttribute exception is raised. I know that this exception is
due to missing permissions settings, but no configuration is working...
This is the code of my viewlet manager :
class WorkflowTransitions(object):
implements(IContentProvider)
adapts(Interface, IDefaultBrowserLayer, Interface)
template = ViewPageTemplateFile('transitions.pt')
def __init__(self, context, request, view):
self.context = context
self.request = request
self.__parent__ = view
def update(self):
wf = zapi.queryUtility(IWorkflow)
if wf is not None:
info = IWorkflowInfo(self.context)
self._transitions = info.getManualTransitionsIds()
else:
self._transitions = []
@property
def transitions(self):
return self._transitions
def render(self, *args, **kw):
return self.template(self, *args, **kw)
I've tryed to define several security declarations in ZCML, but none is
working. The exception is raised while accessing
"getManualTransitionIds()" method :
File ".../onf/publication/browser/viewlets/transition/__init__.py", \
line 45, in update
ids = info.getManualTransitionsIds()
ForbiddenAttribute: ('getManualTransitionsIds', \
)
I've also tried to use a simple content provider with an adapter but got
the same result.

Both date and date/time variants are provided. I've just tried to use "zc.datetimewidget" package in my Zope3 development installation. Installation is fine, as well as widget, but I can't get dates displayed or entered in a french way (DD/MM/). I've tried to modify browser settings as well as a few parameters, but nothing is doing it correctly (and when date is displayed correctly in a form, Zope 'normally' says that dates are not correctly formatted while submitting !). Thanks for any help... Thierry Florac P.S. : I also tried to install and configure "z3c.language" package. Could there be any "inter-dependance" between these two packages ? -- Chef de projet intranet/internet Office National des Forêts - Département Informatique 2, Avenue de Saint-Mandé 75570 PARIS Cedex 12 Mél : [EMAIL PROTECTED] Tél. : +33 01.40.19.59.64 Fax. : +33 01.40.19.59.85 ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] ForbiddenAttribute on "locate" method

Hi,
I try to setup a little application but have a probably little problem
with a ForbiddenAttribute exception on "location.locate" method.
Here is my setup :
class IPhoto(IContainer,IContained):
"""Photo handling interface"""
...
image = Bytes(...)
...
class Photo(Folder):
"""Photo handling class"""
...
image = None
def __init__(self, image=None):
super(Photo,self).__init__()
self.__parent__ = self.__name__ = None
if image:
self.image = image
...
class IEvent(IContained):
"""Event handling interface"""
...
class Event(Persistent):
"""Event handling class"""
...
def __init__(self):
super(Event,self).__init__()
self.__parent__ = self.__name__ = None
In my event creation form (derived from formlib.AddForm), I put
something like this, without a problem :
def create(self, data):
event = Event()
if data.has_key('image'):
event.image = Photo(image=data['image'])
location.locate(event.image, event, 'image')
form.applyChanges(event, self.form_fields, data)
return event
"event.image" access can then be granted easily in an URL through a
"z3c.traverser" plug-in and everything works fine... until now !
Because when I'm trying to make the same thing in an edit form to update
an existing event, an exception is raised :
def edit(self, action, data):
changed = False
event = self.context
if data.has_key('image'):
event.image = Photo(image=data['image'])
location.locate(event.image, event, 'image')
changed = True
return super(EventEditForm,self).edit(action, data) or
changed

Hi,
I finally solved this stupid problem by myself...
Switching "location.locate" method call from "EditForm" view to "Event" class was just enough...

So any help would be great !
