Django add new Model and Form in a new app

i am using Django and trying to add a new model which can only be accessed after user login. Firstly, i built a model class of UserProfile in an app, using

def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance) 
post_save.connect(create_user_profile, sender=User)

to sync the model into database, it works well by calling UserProfile = request.user.get_profile(), then i built Anther model class called "ControlInformation" in ANOTHER app (called "control"), using

def create_control_information(sender, instance, created, **kwargs):
    if created:
        ControlInformation.objects.create(user=instance)
post_save.connect(create_control_information, sender=User)

to sync this model, but there are some problems to use information in this model by calling Current_Status = request.user.get_profile() , which is "'UserProfile' object has no attribute 'turn_on_off'" when calling on_off = Current_Status.turn_on_off in views.py.

Am i right when building this one on one model in another app? Or is there any other problem?

Edit: my ControlInformation model is like this:

class ControlInformation(models.Model):
    user = models.OneToOneField(User)

    TURN_ON_OFF = (
        ('ON', 'On'),
        ('OFF', 'Off'),
    )

    AUTO_MANU = (
        ('ON', 'On'),
        ('OFF', 'Off'),
    )

    TEMP_DINNINGROOM = (
        ('HIGH', 'High'),
        ('MEDIUM', 'Medium'),
        ('LOW', 'Low'),
    )

    TEMP_LIVINGROOM = (
        ('HIGH', 'High'),
        ('MEDIUM', 'Medium'),
        ('LOW', 'Low'),
    )

    turn_on_off = models.CharField(max_length=1, choices=TURN_ON_OFF)
    auto_manu = models.CharField(max_length = 1, choices=AUTO_MANU)
    temp_dinningroom = models.CharField(max_length=1, choices=TEMP_DINNINGROOM)
    temp_livingroom = models.CharField(max_length=1, choices=TEMP_LIVINGROOM)

#signal function: if a user is created, add control information to the user    
def create_control_information(sender, instance, created, **kwargs):
    if created:
        ControlInformation.objects.create(user=instance)

post_save.connect(create_control_information, sender=User)

Then i use this model in views.py like this:

def current_status(request):
    if not request.user.is_authenticated():
        return HttpResponseRedirect('/keenhome/accounts/login/')
    Current_Status = request.user.get_profile()  

    on_off = Current_Status.turn_on_off
    auto_manu = Current_Status.auto_manu
    temp_dinningroom = Current_Status.temp_dinningroom
    temp_livingroom = Current_Status.temp_livingroom

    context = {'on_off': on_off,
               'auto_manu': auto_manu,
               'temp_dinningroom': temp_dinningroom, 
               'temp_livingroom': temp_livingroom,
               }
    return render(request, 'control/current_control_status.html', context)

The on_off = Current_Status.turn_on_off is where problem happens. ('UserProfile' object has no attribute 'auto_manu')

Since you already have request.user.get_profile() to return UserProfile model, You are looking for ControlInformation object in this case. So, just change 

Current_Status = request.user.get_profile()

to 

Current_Status = ControlInformation.objects.get(user=request.user)

Or, 

from django.shortcuts import get_object_or_404
Current_Status = get_object_or_404(ControlInformation, user=request.user)
