Re: [Zope3-Users] So, there is going to be no Zope4... how to handle maintenance a couple of years from now?
Hi, Le Sun, 7 Sep 2014 09:26:43 +0530, Milind Khadilkar zedobj...@gmail.com a écrit: Seems there will be no Zope4. Puts a fond hope to rest. I have one large Zope2 (Zope 2.6) project, one large Zope3 (Zope 3.4) project, two medium sized Grok projects, one GAE project, allof them need to be maintained beyond two years. I would like, if possible, to redevelop them using ONE single framework. While some of the original developers are available, most work would need to be done through people who need to be trained from the ground up. My first choice (mainly because I have a complex Zope3 project to redevelop) would be Bluebream, even if it means using ZCML and programming in ZCA-shackles. But I am speaking without any real experience of it. (Negative press ensured that I did not go for it...) Any suggestions? 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... Regards, Thierry P.S.: by the way, I don't really understand where is the real problem with ZCA (which is so powerful, and not so complicated!) and with ZCML (which is nothing in XML files terms compared to any serious Java server development environment...) ___ Zope3-users mailing list Zope3-users@zope.org https://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Choosing between Bluebream, Zope2 and Grok
Hi, Le Wed, 24 Oct 2012 07:45:50 +0530, Milind Khadilkar zedobj...@gmail.com a écrit: Hello all Zope Users! We are trying to decide on a Zope platform for, say, the next five years. We have developed small products on Zope2 and Zope3 between 2000 and 2008, and in Grok over the past couple of years, off and on. We are looking to build as per customer requirements, and it would be common sense to choose the platform as per requirement. However, with a small team size, we can't spread ourselves thin over the three platforms...Pyramid, Django and GAE also keep beckoning We have seven revivable products in Zope2 (2.6 - 2.10), including one in Plone. Some of them do not open in Zope 2.11... Some of them use DTML for no reason now discernable. Some of them use a very old version of ZODB. We have one big product in Zope 3.3. Can we attempt converting it from Zope 3 to Zope2? We have no real work done in Grok, but there is a level of familiarity with it. Newer members of the team know neither Zope2 nor Zope3. Making use of our past work is an important criterion for us. Training new team members is another... What other things must we keep in mind when deciding on the platform? Any pointers would help. Sorry for this rambling question. Thanks in advance for your answers. 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

Re: [Zope3-Users] Referencing objects
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, Le vendredi 4 février 2011, Michael Seifert michael.seif...@gmx.net a écrit : == Hello everyone, I recently started a Zope3 project, but I am stuck at the very beginning. Although I have some experience with Zope2, the more flexible approach to developing web applications was giving me a really hard start. Let me point out my situation: I created a container hierarchy which is stored in ZODB. Say I have a set of object types A, B, C, D, whose relationships look like the following (edges represent containment, i.e. A contains B,... where B and D are in subcontainers of A): A / \ B D | C C has an attribute referencing an object of type D. As this attribute is mandatory on creation, I created a vocabulary, which ascends the hierarchy from the current context until it reaches A and returns all objects of type D. Now the part that doesn't work: While ascending from C to B and from B to A works fine, descending from A to D returns a security proxied object and since these objects cannot be pickled, I cannot store it's reference in the attribute of C. 1. Is this the way it's meant to be done? :) What is your opinion of storing B and D objects in subcontainers of A? 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. Are there any means to turn the vocabulary into trusted code, so it will not be encapsulated in a proxy (without deactivating the security proxy)? Perhaps can you use the removeSecurityProxy function ? 3. How do you reference objects like you do with foreign keys in relational databases? I want to do this to prevent objects from being saved multiple times. 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.

You probably have a mechanize package (0.1.11) in your default Python

Maybe you should try to create an isolated environment (without site

[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 .

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.

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] 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.

Le mardi 31 juillet 2007 à 11:25 +, Alek Kowalczyk a écrit : Hello, I would like to have an ability to get 'workflow history' for my object. History should contain a list of transitions with from and to states and with timestamps. Have anyone tried to implement such a simple functionality in hurry.workflow, similar to what ClearQuest does? I would be grateful for suggestions how to deal with this. Maybe I've missed something while reading hurry.workflow docs, and it is already available? Hi, I implemented such a functionality by adding a listener on IWorkflowTransitionEvent, which with the help of zc.comment package add comments with source and destination states labels, as well as a few user comments ; these comments are prefixed by special characters so that I can (when needed) filter them easilly, but implementing another cleaner adapter to handle this should be very easy.

Am I wrong ?
You are. There is a SIGUSR2 handler in Signals.Signals, which calls
the 'reopen' method on all active loggers..
Nowhere is there a signal handler that restarts Zope on SIGUSR2.
SIGHUP will cause a restart, SIGINT a shutdown, and SIGTERM a fast
shutdown.
My comment was just based on what I can see in z3.log after running
zopectl logreopen :

Re: [Zope3-Users] Using RAMCache

i would like to cache the results of method in a view, and thougt, that

could be of use here.
After spending a lot of time searching for some documentation or examples, i
came to this:
from zope.app.cache.ram import RAMCache
cache = RAMCache()
query = cache.query('test',key={'x':1})
if query == None:
result = expensive_stuff_method()
cache.set(result, 'test', key={'x':1})
return result
else:
return query
but that won´t work, the cache looses it´s entry, if i call the browser-view
again.
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...

DRAFT = 0 # New document
PROPOSED = 1 # Publication request
CANCELED = 2 # Publication request canceled
REFUSED= 3 # Publication request refused
PUBLISHED = 4 # Publication approved
StateLabels = {
DRAFT : _(status-draft,Draft),
PROPOSED : _(status-proposed,Publication request),
CANCELED : _(status-canceled,Canceled publication
request),
REFUSED : _(status-refused,Refused publication
request),
PUBLISHED : _(status-published,Published)
}
class EventManagerSearchForm(BaseForm):
...
columns = (...
SortableColumn(_('status','Status'),
lambda c,f:
StateLabels.get(IWorkflowState(c).getState())),
...)
@Lazy
def formatter(self):
return Formatter(self.context, self.request,
self.values(),columns=self.columns)
ZPT is as simple :
html i18n:domain=onf
...
table tal:replace=structure view/formatter /
...
/html
My problem is that the StateLabels are translated correctly in several
templates, but not when used inside this table (I can only see the
status-... translation key in generated output).
So any help or advise would be very helpful...
Thanks,
Thierry Florac

No. You would have to write your own code doing that. Note that it really
depends on the security policy on what roles and permissions are available.
My securitypolicy is z.a.securitypolicy :-) .
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 :
adapter
factory=.manager.SecurityManager
provides=.interfaces.ISecurityManager
for=zope.annotation.interfaces.IAnnotatable
trusted=true /
class class=.manager.SecurityManager
allow
interface=.interfaces.ISecurityManager /
/class
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,
Thierry Florac

[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...

Re: [Zope3-Users] Periodically refresh RSS feeds
Le mardi 19 décembre 2006 à 08:17 +0100, Christian Theune a écrit : Hi, Florian Lindner wrote: Hello, I have the following situation: An object represents an RSS feed. It should be updated like every 20 minutes. If there is something new a Jabber message should be send out. Currently I have it implemented with an scheduler loop that emits an refreshRSSFeed event evey 20 minutes. My problem is that a handler for an event must be a static function, but I want a handler function to be called as a member of every instantiated RSS feed object. Another idea I have: Implement an utility where the RSS feeds could register a function that is called every 20 minutes. Another way would be that this utility takes an URL and monitors the URL for changes and only notifies the RSS Feed object in case of a change. How would you do that? So there's two problems here: scheduling and notifying persistent objects about an event. I don't have a good idea about the scheduling right now, except the hint that using a 'zopectl run' script might be worthwhile. I'm not sure what a 'scheduler function is'. About notifying persistent objects: There is a method 'getAllUtilitiesRegisteredFor(interface)' which might help you. Have a look at zope/app/catalog/catalog.py beginning from line 150 (indexDocSubscriber) how the catalog handles events and dispatches them to multiple catalogs. I think this pretty much matches your use case if you make each RSS feed a (named) utility. Of course you could also have a utility that maintains references to all RSS feed objects and simply loops over them and calls a method for refreshing. 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...

Re: [Zope3-Users] Database conflicts errors ?
Le vendredi 08 décembre 2006 à 15:08 +0100, Thierry Florac a écrit : 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... Oops !! Sorry, I found the source of my problem : it was a misconfiguration of the adapter, who was writing data in it's context each time it was called, even if the context was already adapted.

[Zope3-Users] Synchronizing with a remote host

image = Bytes(...)

...
def __init__(self):
super(Event,self).__init__()
self.__parent__ = self.__name__ = None

something like this, without a problem :
def create(self, data):
event = Event()
if data.has_key('image'):
event.image = Photo(image=data['image'])

[Zope3-Users] Localizing Zope3 content
Hi, I'd like to have a few advises about Zope3 content localization. My problem is as follow : - I have to build a new web site ; this site will mainly be in french = OK - some parts of the web site will be available in another language (english, german and spanish) = OK but : - some documents are available in several languages at the same time ; they then have to be seen, from the contributor point of view, as a single document written in several languages (of course, interfaces and available fields will be the same for each language) - the same workflow is applied to all languages, but each language version can be in a different step in the workflow (for example, the french version can be published while the english one still have to be validated and the german is still a draft ; the spanish one have yet to be written...) - from the user point of view, language selection can be done via browser settings or via a cookie-based setting ; but the different versions of a same document have to keep the same URL. From now, I looked at Localizer and other Zope2 localization products which gave me a few ideas, but I'd really like to have as many advises as possible about this problem and the better way it should be handled in Zope3.

You have to define an empty getImages method on the interface.
getImages() is already defined into IPhotoFolder interface. But Philip
already sent a reply with a full and clear explanation of my problem...
But that may not always be possible, so how can I get access to such
methods ??
Why should it not be possible? After all, you defined the FolderInfo
view for the IGalleryFolder _Interface_, not the GalleryFolder class.
What I just mean (but perhaps I'm wrong) is that in my use case, the
getSortedImages() method is only used for presentation purpose in a
specific context, a specific browser view.
I think this kind of method shouldn't have to be defined in an interface
which main goal is to define generic content handling methods...
I don't know if my explanation is clear :-(

An easy workaround is to use sorted():

Note that using 'cmp' is very slow. It's much faster to use 'key':

[Zope3-Users] Question about ForbiddenAttribute...
Hi,
I'm trying to build a sample photos management application for Zope-3.2,
with the following interfaces and classes :
- class IGalleryPhoto(IContainer)
...
- class IGalleryContainer(IContainer)
(marker interface used for preconditions)
- class IGalleryFolder(IGalleryContainer)
def getImages():
...
- class IGallery(IGalleryFolder,IPossibleSite)
...
- class GalleryPhoto(BTreeContainer)
...
- class GalleryFolder(Folder)
def getImages(self):
return [item for item in self.values()
if IGalleryPhoto.providedBy(item)]
- class Gallery(GalleryFolder, SiteManagerContainer)
...
Until now, it's OK !
After that, I created a sample view based on a page template for
IGalleryFolder, using a view class :
- tal:x repeat=image view/getImages ... /tal:x
- class FolderInfo:
def getImages(self):
Get a sorted list of images
result = IGalleryFolder(self.context).getImages()
result.sort (lambda x,y: cmp(IGalleryPhoto(x).name,
IGalleryPhoto(y).name))
return result
The view is registered in ZCML like this :
page
name=images.html
for=.interfaces.IGalleryFolder
allowed_interface=.interfaces.IGalleryPhoto
template=folder_images.pt
permission=zope.View
class=.folder.FolderInfo
menu=zmi_views title=Images /
But when trying to display the view, a ForbiddenAttribute exception is
raised :

My first idea with this problem was to say : a content object can be modified several times during a request execution, sometimes by other content objects and not only by simple editing forms (which automatically fire IObjectModifiedEvent), and I want some kind of expensive application logic (for example, reindexing) to be applied only once, when all modifications are done. So the IEndRequestEvent was, to me, a good place to handle this kind of methods ; but your previous explanation show that I was wrong.

And here is my main configure.zcml part for the adapter :
adapter
factory=.photo.PhotoStorage
provides=.interfaces.IPhotoStorage
for=.interfaces.IGalleryPhoto
trusted=true /
class class=.photo.PhotoStorage
require
permission=zope.View
interface=.interfaces.IPhotoStorage /
require
permission=zope.ManageContent
set_schema=.interfaces.IPhotoStorage /
/class
and finally my browser configure.zcml :
form
name=storage.html
for=.interfaces.IGalleryPhoto
schema=.interfaces.IPhotoStorage
class=.forms.PhotoStorageHandler
fields=identifier hostname
label=Storage
permission=zope.ManageContent
menu=zmi_views title=Storage /
A few print instructions show that :
- PhotoStorageHandler.setData is called correctly, but
- PhotoStorage._setIdentifier is NOT called when setting identifier
property

Well, hum, how could I say that ? Ho, probably just : It's amazing, but it works ! Except if I forgot something (I did so many tries to make this working...), I just rolled back to the previous release of my code, added the object superclass to my adapter, removed my form handler and switched back my ZCML configuration to the editform version of my form... Printed traces shows that everything works fine, and introspector show that my annotations are now updated correctly through my properties... Of course, I'm not sure to really understand the difference between this code and the previous one, and why this object inheritance is so important (I've always thought that every Python class was automatically inheriting from object).

If the for attribute differs from the schema attribute in the edit form, the form will automatically look up an adapter from the context object (implementing the for interface) to the interface specified in schema. I tried to add the for attribute to my configure.zcml editform statement, but the problem I described in several previous post (between march 04 and march 07) remains : - on first read access to the form, annotations (a PersistentDict) are correctly defined - if trying to set values, modifications seems to be applied, but in fact they are lost when refreshing the form (they are probably just extracted from request) and the adapter setters are not called (as seen if printing to standard output). Actually, the only working way I found to update my annotations through my adapters is always to use form directives with the help of a support class using getData/setData methods which call the adapter directly... Any idea ?

I don't build any specific template for this. Should I build any specific SetIndex subclass ? Or define a specific template ?? Thierry, try adding the following to zc.catalog's configure.zcml (this is for all four of the zope.app.catalog-aware indexes). content class=.catalogindex.ValueIndex require permission=zope.ManageServices interface=zope.app.catalog.interfaces.IAttributeIndex zope.index.interfaces.IStatistics set_schema=zope.app.catalog.interfaces.IAttributeIndex / /content content class=.catalogindex.SetIndex require permission=zope.ManageServices interface=zope.app.catalog.interfaces.IAttributeIndex zope.index.interfaces.IStatistics set_schema=zope.app.catalog.interfaces.IAttributeIndex / /content content class=.catalogindex.DateTimeValueIndex require permission=zope.ManageServices interface=zope.app.catalog.interfaces.IAttributeIndex zope.index.interfaces.IStatistics set_schema=zope.app.catalog.interfaces.IAttributeIndex / /content content class=.catalogindex.DateTimeSetIndex require permission=zope.ManageServices interface=zope.app.catalog.interfaces.IAttributeIndex zope.index.interfaces.IStatistics set_schema=zope.app.catalog.interfaces.IAttributeIndex / /content Then give it a try. (This only works if you are using the indexes I listed, but you probably get the idea.) If this helps, we should check it in. Modification is OK (at first, see below) for the first indexes, but an error is raised while starting Zope for the DateTime indexes, because class attribute points to a method name : zope.configuration.config.ConfigurationExecutionError: exceptions.TypeError: type_ must be a type, class or module, not a function DateTimeValueIndex at 0xb672510c in: File /usr/local/zope/3.2/var/lib/python/zc/catalog/configure.zcml, line 58.3-66.3 content class=.catalogindex.DateTimeValueIndex require permission=zope.ManageServices interface=zope.app.catalog.interfaces.IAttributeIndex zope.index.interfaces.IStatistics set_schema=zope.app.catalog.interfaces.IAttributeIndex / /content After removing this modification for the two last indexes, I can access catalog's advanced management screen without error, but information is not really fine : on a SetIndex for example, Document Count and Word Count columns are displayed as security proxied BTrees.Length.Length instance at 0xb4dc052c instead of their numeric values...

Re: [Zope3-Users] Check permissions
Hi,
I think that you can also use something like this :
from zope.security.management import getInteraction
def checkPermission(object, permission='zope.ManageContent'):
interaction = getInteraction()
return interaction.checkPermission(permission, object)
I don't know what's the difference between the two methods, and so I
don't if one of them is better than the other one...

Hi,
how can I test, if the current principal (e.g. by being member in a special
group) has a given permission on a given content object?
Maybe something like this:
if 'zope.ManageContent' in self.context.permissions():
...
This should include all permission defined in ZCML *and* all permission
granted in ZMI.
Thank you for all hints.

Frank
