Re: [Zope-dev] Re: [ZPT] accessing object attributes from python expression raises error
From: Chris McDonough:
meta_type is an attribute, so you can't just do
security.declareProtected(ACCESS_CONTENTS_PERM, 'meta_type')
That's right.
The id attribute has the getId method, perhaps what's required is a
getMetaType method that can be suitably protected?
This would still be a pretty easy fix:
security.declareProtected(ACCESS_CONTENTS_PERM, 'getMetaType')
def getMetaType(self):
return self.meta_type
Am I missing something?
Nope, that would work. But I think also:
meta_type__roles__ = None
.. as a class attr would work as well.
I'll try it and let you know if it works.
security.setDefaultAccess({'meta_type': 1}) should do
the parameter is what has been __allow_access_to_unprotected_subobjects__,
that can be a boolean, dictionary or callable

Now DirectoryViews have FSPythonScripts as attributes, so I'm guessing that when the DirectoryView gets committed to the TemporaryStorage, the FSPythonScripts do as well. ...and apparently they don't like being pickled :-( Ah I see. What's probably happening here is that FSPythonScripts have a file object as an attribute. File objects can't be pickled because files and Python pickles are two different kinds of persistence systems, and the file might go away without the pickle knowing about it. I think the answer here might be don't do that ;-). Note also that the next issue you're going to run in to is that because you can't distribute object references across ZODB databases, and because the sessioning machinery is based on a mounted ZODB storage, that you're not going to be able to store many (any?) objects that are already part of the main storage in the session. You will, however, be able to store newly created objects in the session. waiting-for-your-one-line-question-that-makes-me-retype-docs, ;-) - C ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Interesting. I didn't think you could have more than one
setDefaultAccess in a class. If you can, then you can set:
security.setDefaultAccess('deny')
security.setDefaultAccess({'meta_type': 1})
The last 'setDefaultAccess' statement in a class will define the actual
behaviour, i.e use only one.
But otherwise, you would have to list all attributes of the class in the
dict of a single statement, wouldn't you?
No, all attributes that aren't in the dict are private.

Re: [Zope-dev] sessionDataManager should create it's temp/xxxx
Is it magic if the Session manager creates it's own data container? The first one is created for you but not by the Session system. That seems like magic. Since you say my approach to creating the tempData is flawed from a ZODB stand point. Then rc.d/init.d sound good. Although the /startup folder is a common idea for Windows users. Until the temp folder arrived I didn't need such a thing. Maybe the sessionDataManager could register a callback, called during startup. This might be a safer time to create any required temp data. --Darrell = Darrell Gallion __ Do You Yahoo!? Send FREE video emails in Yahoo!

[Zope-dev] Zope 2.5b3 Management Tabs
I've noticed in a fresh install Zope 2.5b3 management tabs which users do not have access to view show up. In the past only management tabs that a user had permission to view the associated action showed up. Is this a known issue? or a new feature? --Brian Brinegar ECN Web Technician MSEE 104 A 494-3106 http://www.geeksoft.net/ ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] sessionDataManager should create it's temp/xxxx
Darrell Gallion wrote: Is it magic if the Session manager creates it's own data container? The first one is created for you but not by the Session system. That seems like magic. It's created by the Zope package, which indeed is magic, but something needed to populate it with default data; it has the minimum amount of magic necessary ;-) Although the /startup folder is a common idea for Windows users. Until the temp folder arrived I didn't need such a thing. Yup. Maybe the sessionDataManager could register a callback, called during startup. This might be a safer time to create any required temp data. The problem with this is that the SessionDataManager class can do this, but individual instances of the class cannot. There is no efficient way to find all the instances of one kind in a ZODB and call a method on them at start time unless you were to create some sort of custom registry someplace to do keep track of them. It seems cleaner to be procedural ala some sort of etc/rc.d/init.d at startup time which contains scripts that have the power to do arbitrary things to instances in the databse. Then the logic that does the necessary minimal magic in the Zope package now could be moved out and into this. This would be a great idea for a Product. - C ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] sessionDataManager should create it's temp/xxxx
Actually, we did have the Temporary Folder have the capability to automatically import its contents at system startup, but that got tossed out as being function inappropriate to a temporary storage container by executive fiat. Yeah.. I actually think now that this was the right decision. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] poor mans solution to startup folder
External methods aren't the best solution I know.
It wasn't obvious to me how to call python scripts at
this point. For that matter if this is a good point to
do this kind of thing. Or how to hook the startup
event with a product.
Added these lines to the bottom of initialize(app) in
application.py
# Ensure that a startup folder exists
if not hasattr(app, 'startup'):
from OFS import Folder
Folder.manage_addFolder(app, id='startup',
title='Startup')
get_transaction().note('Added startup folder')
get_transaction().commit()
# Call any external methods found in the startup
folder
# Only call external methods
startup = getattr(app, 'startup')
for obj in startup.objectIds():
obj=getattr(startup, obj)
if hasattr(obj,'__call__') and
obj.__class__.__name__=='ExternalMethod':
obj(app)

Re: [Zope-dev] poor mans solution to startup folder
That looks like a workable solution!
This can also be done in a Product by getting hold of the supersecret
attribute of the context object that is passed in to initialize which is
the database connection (or maybe it's the root root object.. in either
case, given either, you can get the other). It might be better that way in
order to keep the logic out of the Zope init routine and in a separate
product so it can be modified outside of Zope and used with various Zope
versions until its baked enough to make it in...
