PODjango add new Model and Form in a new app
text
Body
copied!<p>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</p> <pre><code>def create_user_profile(sender, instance, created, **kwargs): if created: UserProfile.objects.create(user=instance) post_save.connect(create_user_profile, sender=User) </code></pre> <p>to sync the model into database, it works well by calling <code>UserProfile = request.user.get_profile()</code>, then i built Anther model class called "ControlInformation" in ANOTHER app (called "control"), using</p> <pre><code>def create_control_information(sender, instance, created, **kwargs): if created: ControlInformation.objects.create(user=instance) post_save.connect(create_control_information, sender=User) </code></pre> <p>to sync this model, but there are some problems to use information in this model by calling <code>Current_Status = request.user.get_profile()</code> , which is "'UserProfile' object has no attribute 'turn_on_off'" when calling <code>on_off = Current_Status.turn_on_off</code> in views.py.</p> <p>Am i right when building this one on one model in another app? Or is there any other problem?</p> <p>Edit: my ControlInformation model is like this:</p> <pre><code>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) </code></pre> <p>Then i use this model in views.py like this:</p> <pre><code>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) </code></pre> <p>The <code>on_off = Current_Status.turn_on_off</code> is where problem happens. ('UserProfile' object has no attribute 'auto_manu')</p>
