... anyway, after all these experiments I cant open a folder where I put this class. I Traceback (innermost last): ... Module ZODB.Connection, line 554, in setstate Module ZODB.Connection, line 590, in _set_ghost_state SystemError: Failed to import class r from module Record
is there any way to fix it ?
It seems that you stored the result of a Z SQL Method as an attribute of a persistent object. This is impossible as such instances cannot be unpickled (aka unserialized). It might not be easy to fix this problem. If you are lucky, the fatal modification is still listed in your "Undo" tab. In this case, undo the respective transaction. If not, a bit of surgery will be necessary to get rid of the attribute again. There is a HowTo around (I think on ZopeLabs) that explains how to get rid of an object causing a "POSKeyError". A similar approach can be used to get rid of your problematic attribute. BEWARE: do not store Z SQL Method results as part of any persistent object (this also implies: do not store it in a session). By the way: the code fragment you posted seems innocent (with respect to your current problem). The true problem must be elsewhere.
class testclass(SimpleItem, Folder): ... def getTable(self,REQUEST=None): "get table with results" self.parm1=0 self.REQUEST.set('sql',self.sql())
if REQUEST is not None: return
self.showResult_html(self, REQUEST)
