我尝试自定义Django PasswordResetView来验证密码的长度，但我得到了这个错误：

TypeError at /accounts/password_reset/
__init__() missing 1 required positional argument: 'user'

views.py

from django.contrib.auth import views as auth_views

class PasswordResetView(auth_views.PasswordResetView):
    form_class = PasswordResetForm
    template_name = "accounts/users/password_reset.html"
    email_template_name = "accounts/users/password_reset_email.html"
    subject_template_name = "accounts/users/password_reset_subject.txt"
    from_email = settings.EMAIL_HOST_USER
    success_url = reverse_lazy("accounts_password_reset_done")

forms.py

from django.contrib.auth.forms import SetPasswordForm

class PasswordResetForm(SetPasswordForm):

    def clean_new_password1(self):
        password = self.cleaned_data.get("new_password1")
        if len(password) < 12:
            raise forms.ValidationError("Password must be at least 12 characters.")
        return password

很明显，SetPasswordForm类需要在初始化时被用户接受：

class SetPasswordForm(forms.Form):
   . . .
    
    def __init__(self, user, *args, **kwargs):
        self.user = user
        super().__init__(*args, **kwargs)

对于如何将user数据传递给PasswordResetView和PasswordResetForm，我没有找到明确的解决方案，因为用户数据是在创建PasswordResetForm示例时使用的。
