Pregunta
Puedo ver el problema, adjunté mi código y página de error.
En mi plantilla, tengo:
{% if user.get_profile.is_store %}
<!--DO SOME LOGIC-->
{%endif%}
En mi opinión, tengo:
def downloads(request):
"""
Downloads page, a user facing page for the trade members to downloads POS etc
"""
if not authenticated_user(request):
return HttpResponseRedirect("/professional/")
if request.user.get_profile().is_store():
return HttpResponseRedirect("/")
user = request.user
account = user.get_profile()
downloads_list = TradeDownloads.objects.filter(online=1)[:6]
downloads_list[0].get_thumbnail()
data = {}
data['download_list'] = downloads_list
return render_to_response('downloads.html', data, RequestContext(request))

Solución
self.account
apunta a un objeto Account
inexistente cuando intenta procesar is_store ()
. Supongo que está utilizando una base de datos que no aplica claves externas * tos * MySQL * tos *, y sus datos se desordenaron.
Otros consejos
Parece que el valor de retorno de user.get_profile () está vacío y, por lo tanto, falla en la próxima llamada a is_store ():
return not self.account is None
Eso falla, porque self está vacío (es decir, Ninguno).
[editar] Después de leer esto (en Perfiles) parece que el el perfil para ese usuario no existe y, por lo tanto, obtiene la excepción DoesNotExist.
No es redirección lo que no funciona, es su procedimiento is_store () o su perfil no existente. Debe verificar qué es exactamente referencia de self.account.
Por lo que puedo ver al mirar el código, tiene dos tablas en su base de datos: una para baseaccount, que solo almacena la identificación de usuario, y la cuenta, que almacena todos los campos asociados con cuenta + baseaccount id. Puede intentar reemplazar is_store con algo como esto
def is_store(self):
try:
return self.account is None
except Account.DoesNotExist:
return False
De ninguna manera soy un experto en Django, pero creo que esto podría hacer el truco.
