i am using Django to create a user and an object when the user is created. But there is an error
__init__() got an unexpected keyword argument 'user'
when calling the register()
function in view.py.
The function is:
def register(request):
'''signup view'''
if request.method=="POST":
form=RegisterForm(request.POST)
if form.is_valid():
username=form.cleaned_data["username"]
email=form.cleaned_data["email"]
password=form.cleaned_data["password"]
user=User.objects.create_user(username, email, password)
user.save()
return HttpResponseRedirect('/keenhome/accounts/login/')
else:
form = RegisterForm()
return render_to_response("polls/register.html", {'form':form}, context_instance=RequestContext(request))
#This is used for reinputting if failed to register
else:
form = RegisterForm()
return render_to_response("polls/register.html", {'form':form}, context_instance=RequestContext(request))
and the object class is:
class LivingRoom(models.Model):
'''Living Room object'''
user = models.OneToOneField(User)
def __init__(self, temp=65):
self.temp=temp
TURN_ON_OFF = (
('ON', 'On'),
('OFF', 'Off'),
)
TEMP = (
('HIGH', 'High'),
('MEDIUM', 'Medium'),
('LOW', 'Low'),
)
on_off = models.CharField(max_length=2, choices=TURN_ON_OFF)
temp = models.CharField(max_length=2, choices=TEMP)
#signal function: if a user is created, add control livingroom to the user
def create_control_livingroom(sender, instance, created, **kwargs):
if created:
LivingRoom.objects.create(user=instance)
post_save.connect(create_control_livingroom, sender=User)
The Django error page notifies the error information:
user=User.objects.create_user(username, email, password)
and
LivingRoom.objects.create(user=instance)
I tried to search this problem, finding some cases, but still cannot figure out how to solve it.
This question is related to
python
django
django-models
django-forms
django-views
LivingRoom.objects.create()
calls LivingRoom.__init__()
- as you might have noticed if you had read the traceback - passing it the same arguments. To make a long story short, a Django models.Model
subclass's initializer is best left alone, or should accept *args and **kwargs matching the model's meta fields. The correct way to provide default values for fields is in the field constructor using the default
keyword as explained in the FineManual.
I got the same error.
On my view I was overriding get_form_kwargs() like this:
class UserAccountView(FormView):
form_class = UserAccountForm
success_url = '/'
template_name = 'user_account/user-account.html'
def get_form_kwargs(self):
kwargs = super(UserAccountView, self).get_form_kwargs()
kwargs.update({'user': self.request.user})
return kwargs
But on my form I failed to override the init() method. Once I did it. Problem solved
class UserAccountForm(forms.Form):
first_name = forms.CharField(label='Your first name', max_length=30)
last_name = forms.CharField(label='Your last name', max_length=30)
email = forms.EmailField(max_length=75)
def __init__(self, *args, **kwargs):
user = kwargs.pop('user')
super(UserAccountForm, self).__init__(*args, **kwargs)
Check your imports. There could be two classes with the same name. Either from your code or from a library you are using. Personally that was the issue.
