[Zope] 'str' object has no attribute 'other'

Tue Sep 16 04:17:49 EDT 2008

Houston, we have a problem.

Here's the code :

from Products.PageTemplates.PageTemplateFile import PageTemplateFile
from AccessControl                           import ClassSecurityInfo

import Globals

class User() :
    security = ClassSecurityInfo()
    security.declareObjectPublic()
    security.setDefaultAccess("allow")

    def viewProfile(self):
        """
        """
        userProfile = PageTemplateFile("vues/userProfile.pt",globals()).__of__(self)
        return userProfile()

Globals.InitializeClass(Interlocuteur)

And here's what I got :

TypeError: attempt to wrap extension method using an object that is not an extension class instance.

Traceback:

* Module ZPublisher.Publish, line 101, in publish
* Module ZPublisher.mapply, line 88, in mapply
* Module ZPublisher.Publish, line 39, in call_object
...
* Module Products.PageTemplates.Expressions, line 74, in render
* Module Products.GestionnaireInscriptions.Interlocuteur, line 39, in voirFiche

TypeError: attempt to wrap extension method using an object that is not an extension class instance.

Note :

s/Interlocuteur/User/
s/voirFiche/viewProfile/

Besides, this solution do not seem elegant for me, because each time I try to view a user's profile, it requires an instanciation of PageTemplateFile. I find this useless. This PageTemplateFile should be a class attribute.
