[Product-Developers] Cache in an Browser View.

[Christian Klinger]

Hi,

i try to cache a method in a BrowserView.
The result of the view is a list of dicts.


I try to use plone.memoize for this topic.

     @instance.memoize
     def worker(self, data):
         print "WORKING ...."
         ...
         return [{},{}]

If i access this view i got these error:

Traceback (innermost last):
   Module ZPublisher.Publish, line 115, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 41, in call_object
   Module nva.companyinfo.browser, line 57, in __call__
   Module zope.formlib.form, line 769, in __call__
   Module Products.Five.formlib.formbase, line 46, in update
   Module zope.formlib.form, line 750, in update
   Module zope.formlib.form, line 594, in success
   Module nva.companyinfo.browser, line 100, in action_resutls
   Module plone.memoize.instance, line 43, in memogetter
TypeError: dict objects are unhashable


What is the best way to cache this method.
