KeyError at /login
u'message'
Request Method: POST

Exception Type: KeyError
Exception Value:
u'message'
It says that the dictionary attempt does not have the key message. Here you get the dictionary:
attempt = User.objects.validateUser(request.POST)
At this point inspect the value of attempt (print in console, or assert False and deal interactively in browser). If it does not have the value for key message you may provide here (validateUser method) or, let it be optional, and change the way you access the value at:
messages.add_message(request, messages.ERROR, attempt.get('message', 'default_msg'), extra_tags="login")
Note, the changes is from:
attempt.['message']
to
attempt.get('message', 'default_msg')
You can use these two ways.
# either
try:
message = attempt['message']
except KeyError:
message = 'default message or your own message'
# or
message = attempt.get('message', 'default message you need to set it yourself')
# after that just use the message variable
messages.add_message(request, messages.ERROR, message, extra_tags="login")
