Hi all,
I'm using tg1.1 with sqlalchemy
I'm trying to manage all exceptions using @exception_handler
decorator. It works fine for ValueError, TypeError etc.
But for now I am unable to deal with Database Errors using this same
technique:
here's how the code looks like:
1) Definition of the handler, in model.py, before the Root
controller:
def general_except_handler(self,tg_exceptions=None,**kw):
log.error(u'*'+str(datetime.datetime.now())+u'* '+str
(request.path) + u" Exception: " + unicode(str
(tg_exceptions),'latin'))
flash(u"exception::Exception: " + unicode(str
(tg_exceptions),'latin'))
redirect('/')
return dict()
2) Definition, just below the handler, of the catching expression
catch_excep_expr="isinstance(tg_exceptions, (KeyError,TypeError))"
3) I then use it for the controllers with exception_handler decorator
@expose(template="resyweb.templates.generic_form_display")
@exception_handler(general_except_handler,catch_excep_expr)
@identity.require(identity.in_group("admin"))
def edit_reviewer(self,**kw):
It works fine but when I try to include something like SQLAlchemyError
(previously imported with
from sqlalchemy.exceptions import SQLAlchemyError ), I cannot start
the application:
...
in Root
@identity.require(identity.in_group("admin"))

Would anyone know how to find a solution for this problem, or maybe
another technique for catching application-wide database exceptions?
Thanks
