Python Django用户使用自定义用户模型注册无效

我有一个Django自定义用户模型“es_user”，它继承了Django的默认用户模型。当用户注册时，它可以正常工作，但该用户将是“用户”的一部分，并且不会添加任何内容到es_用户。因此，每次用户注册时，我都必须进入管理面板，将已登录的“用户”添加到“es_用户”

为了解决这个问题，我将这2行添加到views.py

 es_user_instance = es_user.objects.create(user= req_user)
 es_user_instance.save()

class es_user(models.Model):
user = models.OneToOneField(User,related_name='es_user', on_delete=models.CASCADE)

def signup(request):
signup_form_instance = SignUpForm()

if request.method == "POST":

    signup_form_instance = SignUpForm(request.POST)
    if signup_form_instance.is_valid():
        signup_form_instance2 = signup_form_instance.save(commit = False)
        req_user = request.user
        signup_form_instance2.password = make_password(signup_form_instance.cleaned_data['password'])
        signup_form_instance2.save()
        es_user_instance = es_user.objects.create(user= req_user)
        es_user_instance.save()

        return index(request)#successful signup redirect or return
    else:
        print("SIGN UP FORM INVALID")

return render(request,'signup.html',{'signup_form':signup_form_instance})

class SignUpForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ('username', 'email', 'password')

这给了我这个错误

ValueError at /signup/

Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x7f9c787b9be0>>": "es_user.user" must be a "User" instance.

视图.py

 es_user_instance = es_user.objects.create(user= req_user)
 es_user_instance.save()

class es_user(models.Model):
user = models.OneToOneField(User,related_name='es_user', on_delete=models.CASCADE)

def signup(request):
signup_form_instance = SignUpForm()

if request.method == "POST":

    signup_form_instance = SignUpForm(request.POST)
    if signup_form_instance.is_valid():
        signup_form_instance2 = signup_form_instance.save(commit = False)
        req_user = request.user
        signup_form_instance2.password = make_password(signup_form_instance.cleaned_data['password'])
        signup_form_instance2.save()
        es_user_instance = es_user.objects.create(user= req_user)
        es_user_instance.save()

        return index(request)#successful signup redirect or return
    else:
        print("SIGN UP FORM INVALID")

return render(request,'signup.html',{'signup_form':signup_form_instance})

class SignUpForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ('username', 'email', 'password')

forms.py

 es_user_instance = es_user.objects.create(user= req_user)
 es_user_instance.save()

class es_user(models.Model):
user = models.OneToOneField(User,related_name='es_user', on_delete=models.CASCADE)

def signup(request):
signup_form_instance = SignUpForm()

if request.method == "POST":

    signup_form_instance = SignUpForm(request.POST)
    if signup_form_instance.is_valid():
        signup_form_instance2 = signup_form_instance.save(commit = False)
        req_user = request.user
        signup_form_instance2.password = make_password(signup_form_instance.cleaned_data['password'])
        signup_form_instance2.save()
        es_user_instance = es_user.objects.create(user= req_user)
        es_user_instance.save()

        return index(request)#successful signup redirect or return
    else:
        print("SIGN UP FORM INVALID")

return render(request,'signup.html',{'signup_form':signup_form_instance})

class SignUpForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ('username', 'email', 'password')

谁能告诉我哪里出了问题

注意：我使用了此自定义用户模型，因为稍后我将向“es_user”添加更多字段。

问题在于

req_user=request。由于您尚未登录该用户，用户

正在返回一个

匿名用户

。因此，在使用

request.user

之前，首先

或者，您可以只添加刚刚创建的用户而不登录：

es_user_instance = es_user.objects.create(user=signup_form_instance2)

谢谢@damores我已经尝试了你建议的两种方法，效果很好
