Question

我想创建一个用于重置用户密码的表单。它应该是current_password，然后是new_password和confirm_new_password。我能够进行验证以检查新密码是否匹配。我如何验证current_password？有没有办法将User对象传入表单？

Answer 1

Django附带内置PasswordChangeForm，您可以在视图中导入和使用。

from django.contrib.auth.forms import PasswordChangeForm

但您甚至不必编写自己的密码重置视图。有一对视图django.contrib.with.views.password_change和django.contrib.auth.views.password_change_done，您可以直接连接到您的网址配置。

我使用了上面的链接并进行了一些更改。他们在下面：

class PasswordForm(forms.Form):
    password = forms.CharField(widget=forms.PasswordInput, required=False)
    confirm_password = forms.CharField(widget=forms.PasswordInput, required=False)
    current_password = forms.CharField(widget=forms.PasswordInput, required=False)

    def __init__(self, user, *args, **kwargs):
        self.user = user
        super(PasswordForm, self).__init__(*args, **kwargs)

    def clean_current_password(self):
        # If the user entered the current password, make sure it's right
        if self.cleaned_data['current_password'] and not self.user.check_password(self.cleaned_data['current_password']):
            raise ValidationError('This is not your current password. Please try again.')

        # If the user entered the current password, make sure they entered the new passwords as well
        if self.cleaned_data['current_password'] and not (self.cleaned_data['password'] or self.cleaned_data['confirm_password']):
            raise ValidationError('Please enter a new password and a confirmation to update.')

        return self.cleaned_data['current_password']

    def clean_confirm_password(self):
        # Make sure the new password and confirmation match
        password1 = self.cleaned_data.get('password')
        password2 = self.cleaned_data.get('confirm_password')

        if password1 != password2:
            raise forms.ValidationError("Your passwords didn't match. Please try again.")

        return self.cleaned_data.get('confirm_password')
