I need to check if Model.objects.filter(...) turned up anything, but do not need to insert anything. My code so far is:

user_pass = log_in(request.POST)  # form class
if user_pass.is_valid():
    cleaned_info = user_pass.cleaned_data
    user_object = User.objects.filter(email = cleaned_info['username'])
model view django python database

If the user exists you can get the user in user_object else user_object will be None.

try:
    user_object = User.objects.get(email = cleaned_info['username'])
except User.DoesNotExist:
    user_object = None
if user_object:
    # user exist
    pass
else:
    # user does not exist
    pass
