Re: [Zope3-Users] Need help with a Five / Viewlet Configuration Problem
It turned out that the problem was the viewlet manager. It was using the
zope.viewlet.manager instead of the Five.viewlet.manager baseclasses. Once
I changed the viewlet manager it worked fine.
Kevin
I am getting a ForbiddenAttribute error on 'render' when I try to display
a viewlet in my Zope2 application.
I am running zope 2.11.2 + Five. I am currently working on integrating
grok + z3c.form into our stack.
I have security a problem configuring the
z3c.formjs.interfaces.IDynamicJavaScript viewlet.
The viewlet configuration (in z3c.formjs) seems standard...
browser:viewlet
name=z3c.formjs.subscriptions
manager=.interfaces.IDynamicJavaScript
view=z3c.formjs.interfaces.IHaveJSSubscriptions
class=z3c.formjs.jsevent.JSSubscriptionsViewlet
permission=zope.Public
layer=z3c.form.interfaces.IFormLayer
/
The viewlet is very standard.
When I run the system, the viewlet is wrapped using the
Products.Five.viewlet.metaconfigure functionality to provide a wrapped
viewlet.
However, when I run the application, I get this error...
Module zope.viewlet.manager, line 107, in update
Module zope.viewlet.manager, line 85, in filter
Module zope.security.checker, line 134, in canAccess
ForbiddenAttribute: ('render',
Products.Five.viewlet.metaconfigure.JSSubscriptionsViewlet object at
0x84c0410)
It appears to me that, at runtime, an incorrect 'checker' is being picked
up. I believe that I should be seeing a call to
Products/Five/security.py:checkPermission, but I believe I am picking up a
different checker.
I cannot seem to debug the checker, even though I set
security-policy-implementation python in the zope.conf.
Other (possibly) relevant information...

If I'm not mistaken, this error typically occurs when you try to hold a
reference to a Persistent object across transaction boundaries (e.g. by
storing it in a global). Don't do that.
Sometimes this happens in unexpected places (e.g. having a schema with
an Object field that has a default value, and an edit form -- the
default value is never explicitly copied, so you may end up with
multiple references to it). I'm not saying this could be your problem;
I'm just trying to remind you that some globals may be difficult to
notice if you haven't been burned by them before.
First thanks for the response.
Once the server gets into this state, it seems to repeat often.
The object in question is a database connection object.
Are you talking about the persistent object with oid 0x1d54?
The object class is known to me. It is a the postgres database adapter.
I found this issue, which may cause the problem...
I used to use a database adapter configured as a local utility. However, I
changed to configuring it as a global utility because I need to access the
database in some event subscribers and the event subscribers. I deleted
the database adapter from my ++etc++site, but when I looked at the
@@registrations.html view it was still there. I have removed the adapter
using the @@registrations.html view and restarted.
Unfortunately the problem takes some time to recur and I cannot replicate
it in my test server, so I cannot be sure that this is a resolution.
I have just
retrieved it via an adapter lookup. It is not stored.
connection= zope.component.getUtility(IZopeDatabaseAdapter,
CONNECTION_NAME, self.context)()
The database connection is provided by a global utility. The important
code is as follows:
def connection_directive(_context, name=CONNECTION_NAME,
connection_string='', encoding='latin-1'):
Process a db:Connection zcml directive
# Don't delay to the end of the configuration process -
gAdapter = PsycopgAdapter(connection_string)
gAdapter.setEncoding(encoding)
gAdapter.connect()
provideUtility(gAdapter, IZopeDatabaseAdapter, name)
This looks okay-ish to me (latin-1, yuck, is this the 20th century
still?).
I am in a parallel run. I can migrate to utf-8 only after I switch off the
old system but I will - I need those euro symbols.
Any help in narrowing down this problem would be greatly appreciated. It
is making my live system unworkable.
Start a debug console (zopectl debug or bin/debugzope), then take a look
at oid 0x1d54:
from ZODB.utils import p64
app.root()._p_jar.get(p64(0x1d54))
The interesting bit of information is the class name of that object.
Then look through the sources trying to determine the lifetime of that
object: where are references to it created?
That is just what I needed.
Although I had removed a registration for the deleted object, your snippet
showed me that the object was still in my ZODB. I eventually tracked down
the object as a 'subscriber' to utilities in a local registry
I deleted the object using...
lsm = root['mysite'].getSiteManager()
from zope.rdb.interfaces import IZopeDatabaseAdapter
# Display the adapter (direct and indirect)
print lsm.utilities._subscribers[0][IZopeDatabaseAdapter]
print lsm.utilities.subscriptions((), IZopeDatabaseAdapter)
import transaction
transaction.begin() # this may not be necessary
# Delete the adapter
lsm.utilities.unsubscribe

Re: [Zope3-Users] Zope3 and SQLAlchemy
I investigated these last month. At the high-level there are two options, ORM or Direct SQL. If you are going down the route of ORM, there are two well supported and active ORMs, SQLAlchemy and Storm. If you are going with alchemy, there are several options. I made a few notes as I was looking at them. For my purposes ore.alchemist and storm suited best. Here are my notes... dobbin: - Works like ZODB - Creates tables on the fly - No control over the schema - built on ore.alchemist - I failed to get this working. The documentation is not ZCML friendly. The connection mechanism is undocumented. It requires that UUID functionality is installed in postgreSQL. z3c.sqlalchemy - intergrates zope.sqlalchemy (see below) - provides a configuration mechanism - No integration to interfaces z3c.zalchemy (abandoned) - Integration of SQLAlchemy to Zope Transactions - Integration of interfaces - objects work like zope objects collective.lead - See Martin Aspellis book - Not zope objects (plone - archetypes) - see zope.sqlalchemy below zope.sqlalchemy - attempt to unify the integration of SQLAlchemy to the Zope transaction management machinery - Allows sqlalchemy to work in a Zope instance. - provides NO configuration mechanism z3c.saconfig - layer to provide 'scoped session support' on top of zope.sqlalchemy - SQLAlchemy session factory is a zope utility - Note: you cannot connect to the database during the xmlconfig pass. include package=z3c.saconfig file=meta.zcml / db:engine url=posgres://name:[EMAIL PROTECTED]/databasename echo=True / db:session twophase=True / ore.alchemist - of the alchemy ORM approaches, this worked best for me - simple container based mechanism for mapping a file to the ORM - 'bind' meta directive controls meta-data lookup after database connect Also, if you are going with SQL database only, have a look at lovey.zetup. This provides a ZODB'less mechanims for building your site. I hope this helps, Kevin Hi, I currently have to integrate an SQL database (PostgreSQL, with PostGIS extensions) into my Zope3 application. I'd like to use SQLAlchemy to handle this, and I've seen that several packages are available : z3c.zalchemy, z3c.sqlalchemy, zope.sqlalchemy... So my questions are simple : - what package is the best to plug into my Zope (3.3.1) application ? - do all these packages handle the same features ??

[Zope3-Users] z3c.selectWidget terms without vocabulary
I want to create a select widget based on a field which does not have a vocabulary. The possible values are determined based on the context or the view. How do I configure the z3c SelectWidget to pick up the terms from a set of terms I provide, rather than looking to the field. I see from the code that it looks up a registered adapter, but I don't understand how to control this on a view instance basis.

Re: [Zope3-Users] z3c.selectWidget terms without vocabulary
OK, I have it working now. Here is what I did... 1. Subclass the schema type to create a specific class for my field, e.g. class LocalChoice(zope.schema.Choice): Marks this field uniquely 2. Make a new class based on z3c.form.terms.ChoiceTerms, and register it for the view and the schema field: zope.component.adapts( zope.interface.Interface, z3c.form.interface.IFormLayer, ViewClass, LocalChoice, z3c.form.interfaces.IWidget) 3. Put in the zcml adapter ... And it is picked up fine. Thanks Kevin I want to create a select widget based on a field which does not have a vocabulary.

Re: [Zope3-Users] Help: I cannot login after installing z3c.formjs
Thanks for the analysis. I did some digging and found that it was entirely
my own fault. I have some code in the SessionCredentials object which
stores the request annotations. I do this to handle extra information on
the login form, e.g. login groups.
Hmm, I've never gotten an error like that. It probably wouldn't be
too difficult to patch jsclientevent.py by making sure caught events
have security proxies removed before they are stored. But I wonder
why any request related data is being stored in the database. My
understanding is that session data gets stored in the database but is
totally separate from the request. A cookie (stored in the request)
is used to lookup the session data from the database. My gut instinct
is that there is something wrong with the credentials plugin you are
using because request annotations should never be persisted across
multiple requests. I am using SessionCredentials myself without any
problems. Can you find the code path that tries to store the request
annotation?
From a z3c.formjs perspective, if you want the caught events to not be
security proxied, you could create another object event listener (like
the one in z3c/formjs/jsclientevent.py) that goes through the caught
events and removes security proxies. In the end this is a fragile
solution because you can't guarantee the order in which events are
handled, and unfortunately the way the zcml configuration is split up
(not at all), it would be difficult to override this default event
handler using an exclude directive.
I'm currently making some improvements to z3c.formjs and will make
sure to split up the zcml files more so doing such a customization is
easier. There should be new releases of z3c.form and z3c.formjs in
the next couple of weeks with these changes.
I will be interested in seeing where you are going with formjs. I am
really using it to get the AjaxRequestHandler at the moment.
Thanks
Kevin

Re: [Zope3-Users] Zope 3 security model
1. First, I believe you need Groups. In your Group folder, you set up logical groups. You assign permissions to the groups and then assign one or more groups to your membership. 2. For the owner, it depends on whether the owner is Zope information or not. In my environment, I have members who own listings. That information is stored on the relational database. I use a PrincipalRoleMap to map owners to objects. In my environment the 'owner' has less privileges than administrators so it is a bit different for the standard Zope concept of an owner.

The copy/paste/move adapters are configured as zope.ManageContent, and I don't want these users to have the rest of zope.ManageContent. Just be able to copy content types that they can create. I tried includeOverrides but that just gave a duplication error. I tried registering a new adapter, but the original adapter was always used.

Re: [Zope3-Users] Best Practices - Zopeproject Deployment
So, I am now thinking that I will have to have instructions in my installation instructions that tell developers to edit the 'eggs-directory' line; correct? Also they will need to install buildout (or zopeproject) and create a project space before doing the checkout? You can avoid storing user specific information in your buildout.cfg by creating a ~/.buildout/default.cfg file in your home directory that contains user specific information: [buildout] eggs-directory = /Users/kteague/buildouts/shared/eggs If you leave the eggs-directory line out of a buildout.cfg, and it doesn't exist within a developer's ~/.buildout/default.cfg file, then buildout will simply create an eggs directory inside the project and put all of the eggs there. Quite tedious if you are working on a lot of buildouts since you will have multiple copies of the same eggs, but for production deployments you may wish for the entire buildout to be placed in a single isolated location - or if your developer's are only working on a single buildout-based project then they don't need to worry about setting/using the eggs-directory setting. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] How can I find all Local Registries (Sites)
How can I find all Local Registries (Sites)? I have a simple local utility that I need to register with a global utility when bootstrapping the application. I can find my global utility since it is in the global site manager. I registered my sites with the base local registry. I tried using the IDatabaseOpenedEvent and opening the database and getting the Application object and the root local registry. However, the local utilities I instantiate believe that they are in the global Registry. There is also a problem deleting a site which registered itself with a parent.

[Zope3-Users] How do I set up layers for functional testing
I am trying to use the functional test tools on pages created with the z3c.forms library. zopeproject created a function testing layer for me in testing.py and matching ftesting.zcml. When I setup my z3c.forms layouts I registered my own layer and configured them on that specific layer (rather than the default layer). How do I functional test my z3c.forms views (in this scenario)? do I re-register the layout stuff on the functional layer? do I register the layout stuff directly and templates directly for the test. I found a snippet which does this for unittesting? or is there a way to get testing.py FunctionalLayer to inherit / include my application layer(s)? do I write simpler layout templates and register them for functional testing? or do I go read a good manual page on functional testing and layers that you can direct me to? :-) Thanks, Kevin ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Unfortunately, the session-credentials extractor doesn't provide an API to do this. This would be a worthy addition. We have an internal session-credential extractor that does this. I don't have time to work this into the version in zope.app.authentication, but if someone wants to work on this, I'd be happy to check my code into the sandbox for someone to work from.

[Zope3-Users] z3c.formjs in a viewlet
I am trying to put a z3c.formjs form into a viewlet. I run into a problem with the generation of the JSSubscriptions code in the resulting page. By default the formjs code puts the IHaveJSSubscriptions marker interface and the jsSubscriptions variable on the viewlet rather than the view. There is little difficulty in copying these to the view in the update() method. However, the set viewlets seem to be selected before my form viewlet begins to operate. Thus the viewlet selection code doesn't see the IHaveJSSubscriptions marker interfaces. (Am I making sense so far). My question is - how should I work around this problem? - I can mark the view in advance - I can render the subscriptions in the viewlet and thus have javascript in the body of the html result - I can give up and put the form in an IFrame Any suggestions?

[Zope3-Users] Viewlet Manager Configuration
Is it possible to pass parameters from a skin page template to a Viewlet Manager? The requirement is to use the same Viewlet Manager in different places on a page, and control the content based on configuration information. For example: Adverts are served on pages with unique slot information to track clicks. If we use a Viewlet Manager to display adverts, the page template could pass the slot id through to the Viewlet Manager, which ultimately could use this information to generate HTML with appropriate links. The alternative is to create multiple of Viewlet Managers with the contextual information coded in python. ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

I am extending the example so that the information entered when creating the Principal is copied to the Annotations. Thus I can present the user with a one step sign-up.

My questions are ... Can I set metadata on an object in the interaction in which the object is being created? I am assuming that the principal returned by the FoundPrincipalFactory is the same as a normal principal when the use is logged in. Is this assumption valid? Is the meta data approach the best approach? Would it be easier to replace the InternalPrincipal with a content object which contains my new data? If I do that can I access that data via the standard principal machinery?
