大家好，当我创建一个带有信号的用户配置文件时，我们遇到了一个问题，当我进入寄存器部分时，'str'对象没有属性'get'，如果你能帮忙，我会很高兴的
我的观点：

from django.shortcuts import render,redirect
from .forms import LoginForm,RegisterForm
from django.contrib.auth import authenticate,login,logout
from django .contrib.auth.models import User

# Create your views here.

def Login_view(request):
    form=LoginForm(request.POST or None)
    if form.is_valid():
        username=form.cleaned_data.get('username')
        password=form.cleaned_data.get('password')
        user=authenticate(username=username,password=password)
        login(request,user)
        return redirect('index')
    return render(request,'accounts/login.html',{'form':form})

def Register_view(request):
    form=RegisterForm(request.POST or None)
    if form.is_valid():
        user=form.save(commit=False)
        password=form.cleaned_data.get('password1')
        user.set_password(password)
        user.save()
        new_user=authenticate(username=user.username,password=password)
        login(request,new_user)
        return redirect('index')
    return render(request,'accounts/register.html',{'form':form})

def logout_view(request):
    logout(request)
    return redirect('index')

我的信号

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver 
from .models import UserProfile

@receiver(post_save,sender=User)
def create_profile(sender,instance,created,**kwargs):
    if created:
        UserProfile.objects.create(user=instance)

@receiver(post_save,sender=User)
def save_profile(sender,instance,**kwargs):
    instance.profile.save()

我的模型：

class UserProfile(models.Model):
    user=models.OneToOneField(User, on_delete=models.CASCADE)
    username=models.CharField(verbose_name='Kullanıcı Adı',max_length=40)
    name=models.CharField(verbose_name='ad',max_length=40)
    surname=models.CharField(verbose_name='Soyad',max_length=40)
    bio=models.TextField()
    avatar=models.ImageField(null=True,blank=True)

登录表单：

class LoginForm(forms.Form):
    username=forms.CharField(max_length=50,label='Kullanıcı Adı')
    
 
 password=forms.CharField(max_length=50,label='Parola',widget=forms.PasswordInput)

    def clean(self):
        username=self.cleaned_data.get('username')
        password=self.cleaned_data.get('password')
        if username and password:
            user=authenticate(username=username,password=password)
            if not user:
                raise forms.ValidationError('Kullanıcı adı veya parola yanlış!')
        return super(LoginForm,self).clean()

登记表：

class RegisterForm(forms.ModelForm):
    username=forms.CharField(max_length=100,label='Kullanıcı Adı')
    password1=forms.CharField(max_length=100,label='Parola',widget=forms.PasswordInput)
    password2=forms.CharField(max_length=100,label='Parola Doğrulama',widget=forms.PasswordInput)

    class Meta:
        model=User
        fields=['username','password1','password2',]

    def clean(self):
        password1=self.cleaned_data.get('password1')
        password2=self.cleaned_data.get('password2')
        if password1 and password2 and password1!=password2:
            raise forms.ValidationError('Parolalar eşleşmiyor!')
        return password2
