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.
