This is a common problem and isn't really related to the code *inside* the class.  It's related to other code that doesn't properly acquisition wrap the instance.  IOW, the code you're showing us isn't the code that is broken; the problem lies in some other piece of code that unwraps the object (or rewraps it improperly) at a point where it needs to continue to rely on having a good acquisition context.

This isn't really a Zope bug, it's an application bug.

= Request - Entry #1 by jdoyon on Apr 13, 2005 4:57 pm

I'm trying to get to the current REQUEST object from within some product code, and am not having any luck.

Apparently "self" (Where "self" is the instance of a persistent class) has an attribute called REQUEST, but it's a string that says: <Special Object Used to Force Acquisition> ...

So where I have this:

    def getCurrentLanguage(self):
        if hasattr(self, 'REQUEST') and self.REQUEST.get('HTTP_ACCEPT_LANGUAGE', None) in self.pathlocalizer.supported_languages:
            return self.REQUEST.get('HTTP_ACCEPT_LANGUAGE', None)
        else:
            return self.pathlocalizer.supported_languages[0]

I get told that "str" object doesn't have a "get" function/method.

Thanks,
J.F.
