Hi Tom, Thanks for your reply. (You're right, my example was lousy). I did in fact try what you suggested earlier on, and got the the following error: AttributeError at /people/add/ 'ValidationError' object has no attribute 'message_dict' Request Method: POST Request URL: http://localhost:8000/people/add/ Django Version: 1.3 rc 1 SVN-15755 Exception Type: AttributeError Exception Value: 'ValidationError' object has no attribute 'message_dict' Exception Location: /home/benjamin/Ion/ellieharrison/trajectories/ views.py in playeradd, line 298 Python Executable: /usr/bin/python Python Version: 2.6.6 Python Path: ['/home/benjamin/Ion/ellieharrison', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/home/benjamin/django-trunk', '/usr/lib/python2.6/dist-packages/gst-0.10', '/usr/lib/pymodules/python2.6', '/usr/lib/python2.6/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.6/gtk-2.0'] Server time: Tue, 15 Mar 2011 14:27:13 +0000 I have this in the code: from django.core.exceptions import ValidationError, NON_FIELD_ERRORS and the code is currently so: except ValidationError, e: errormsg = e.message_dict[NON_FIELD_ERRORS] form = EditPerson() return render_to_response('personentry.html', { 'form' : form, 'errormsg': errormsg },context_instance=RequestContext(request)) Here's the full traceback: Environment: Request Method: POST Request URL: http://localhost:8000/people/add/ Django Version: 1.3 rc 1 SVN-15755 Python Version: 2.6.6 Installed Applications: ['django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.admin', 'trajectories'] Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware') Traceback: File "/home/benjamin/django-trunk/django/core/handlers/base.py" in get_response 111. response = callback(request, *callback_args, **callback_kwargs) File "/home/benjamin/django-trunk/django/contrib/auth/decorators.py" in _wrapped_view 23. return view_func(request, *args, **kwargs) File "/home/benjamin/Ion/ellieharrison/trajectories/views.py" in playeradd 298. errormsg = e.message_dict[NON_FIELD_ERRORS] Exception Type: AttributeError at /people/add/ Exception Value: 'ValidationError' object has no attribute 'message_dict' -- You received this message because you are subscribed to the Google Groups "Django users" group.
