Question

请帮助解决错误

我在forms.py

中检查用户的密码

from django import forms
from userprofile.models import UserProfile
from django.contrib.auth.models import User
from django.forms import ModelForm

class ChangePasswordForm(forms.Form):
    password_old = forms.CharField(max_length=30)
    password1 = forms.CharField(widget=forms.PasswordInput())
    password2 = forms.CharField(widget=forms.PasswordInput())

    def clean_password_old(self):
        cleaned_data = self.cleaned_data
        password_old = cleaned_data.get("password_old") 
        if not User.check_password(password_old):
            raise forms.ValidationError("Passwords is not correct")
        else:
            return cleaned_data

    def clean(self):    
        cleaned_data = self.cleaned_data
        password1 = cleaned_data.get("password1")
        password2 = cleaned_data.get("password2")

        if password1 != password2:      
            raise forms.ValidationError("Passwords must be same")
        else:                           
            return cleaned_data

但在屏幕上提交表单后会收到以下错误消息：

TypeError at /userprofile/password_page/
check_password() missing 1 required positional argument: 'raw_password'
Request Method: POST
Request URL:    http://127.0.0.1:8000/userprofile/password_page/
Django Version: 1.6.2
Exception Type: TypeError
Exception Value:    
check_password() missing 1 required positional argument: 'raw_password'

这一行没有意义：

if not User.check_password(password_old):

您在User类上调用check_password，而不是在实例上调用{{1}}。但您需要检查实际用户的密码，这意味着您必须实际拥有该用户。

无论如何，自己写这篇文章毫无意义。 Django已经包含一个带有表单的change_password视图：请参阅the documentation。

如何在django1.6中查看密码？
