__init __（）得到了一个意想不到的关键字参数'user' [英] __init__() got an unexpected keyword argument 'user'

问题描述

我在创建用户时使用Django来创建用户和对象。但是有一个错误

i am using Django to create a user and an object when the user is created. But there is an error

__ init __（）得到一个意想不到的关键字参数'user'

。
该功能是：

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))

，对象类为：

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)

Django错误页面通知错误信息：
user = User.objects.create_user（用户名，电子邮件，密码）
和
LivingRoom.objects.create（user = instance）

The Django error page notifies the error information: user=User.objects.create_user(username, email, password) and LivingRoom.objects.create(user=instance)

我试图搜索这个问题，找到一些案例，但仍然无法弄清楚如何解决它。

I tried to search this problem, finding some cases, but still cannot figure out how to solve it.

推荐答案

你不能做

LivingRoom.objects.create(user=instance)

因为你有一个不采取用户作为参数。

because you have an init method that does NOT take user as argument.

你想要一些类似

#signal function: if a user is created, add control livingroom to the user    
def create_control_livingroom(sender, instance, created, **kwargs):
    if created:
        my_room = LivingRoom()
        my_room.user = instance
