[Zope-dev] getting size of zope.schema.List from a view in bluebream
Hello all,
While trying to get the length of zope.schema.List field in a view
(like this: len(self.context.list_field) I get the following error
ForbiddenAttribute: ('__len__', [])
Even though my zcml configuration for that class is defined as below
class class=.app.MyObject
require
permission=zope.Public
interface=.interfaces.IMyObject
/
require
permission=zope.Public
set_schema=.interfaces.IMyObject
/
/class
I still get the above error. To circumvent this issue, I added a method
in the interface like say 'getListSize()' which has the following
implementation
class MyObject(persistent.Persistent):
implements(IMyObject)
name = u''
list_field = PersistentList()
...
def getListSize(self):
return len(self.list_field)
This solves my issue. However, I am curious to know whether is this the
only solution available to the above issue. Am I going in the right
direction?
Please guide me.

Hello,
You forgot to paste interfaces.IMyObject definition.

This solves just the '__len__' issue. But if do the slice operation like
this
self.context.list_field[offset:limit]
I get the following error
ForbiddenAttribute: ('__getslice__',[...])
I guess my approach is flawed. Implementing all the functionality (like
the one I did for length) that a list provides is a overkill. So, please
guide me in this regard.
Thanks

Joshua,
I think it's really difficult to work out what you are trying to do.
Please state your problem more clearly. Are you still using zope.form or
are you using z3c.form?

Re: [Zope-dev] getting size of zope.schema.List from a view in bluebream
Hello,
Well using removeSecurityProxy is not so nice.
If there's really a list in your property, then zope should give you
zope.Public access:
_default_checkers = {
...
list: NamesChecker(['__getitem__', '__getslice__', '__len__',
'__iter__',
'__contains__', 'index', 'count', '__str__',
'__add__', '__radd__', ]),
...
Can you do:
from zope.security.proxy import removeSecurityProxy
li = removeSecurityProxy(self.context.list_field)
print type(li)

As I am using the persistent List in the implementation of IMyObject,
the output of the above is
class 'persistent.list.PersistentList'
So, How can I access its inbuilt methods without removing the security
proxy. Please guide me.

Including that file in zcml solved the issue. include package=zope.app.security file=_protections.zcml / Apart from the PersistentList and PersistentDict I see many other BTree related allow attributes configurations. I guess these configurations are not available in any other place and including this '_protections.zcml' is safe. Thanks for the tip.
