使用Django实现用户修改密码

class CodeForm(forms.Form):
        oldpassword = forms.CharField(label=‘原密码:‘,max_length=30)
        newpassword1 = forms.CharField(label=‘修改密码:‘,widget=forms.PasswordInput())
        newpassword2 = forms.CharField(label=‘再次输入:‘,widget=forms.PasswordInput())
        def pwd_validate(self,p1,p2):
                return p1 == p2
