它第一次工作但数据库条目为空。第二次它给出了这个错误。

forms.py

    signup_email = forms.EmailField(required=True)

    signup_first_name = forms.CharField(required=True)
    signup_last_name = forms.CharField(required=True)
    signup_country_code = forms.CharField(required=True)
    signup_mobile = forms.CharField()

    def __init__(self, *args, **kwargs):
        super(SignupForm, self).__init__(*args, **kwargs)
        self.fields['signup_email'].widget.attrs.update({'placeholder': "Email"})
        self.fields['signup_password'].widget.attrs.update({'placeholder': 'Password'})

    def clean_signup_confirm_password(self):
        if self.cleaned_data.get('signup_password') and self.cleaned_data.get('signup_password'):
            if self.cleaned_data.get('signup_password') != self.cleaned_data.get('signup_confirm_password'):
                raise forms.ValidationError("The two password fields must match.")
        return self.cleaned_data['signup_confirm_password']

尝试按照这样的方式编辑视图，

def form_valid(self, form):
    email = form.cleaned_data['signup_email']
    password = form.cleaned_data['signup_password']
    user, created = models.User.objects.get_or_create(username=email, email=email)           
    if created: 
        user.set_password(password)
        user.save()
        models.Profile.objects.create(
            user=user,
            mobile=form.cleaned_data["signup_mobile"],
            country_code=form.cleaned_data["signup_country_code"]
        )
    user_obj = authenticate(username=user.username, password=user.password)
    if user is not None:
        login(self.request, user_obj)            
    return super(SignUpView, self).form_valid(form)
