From Classy Class Based Views PasswordChangeView

A view for displaying a form and rendering a template response.

Attributes

• form_class: The form that will be used by the template created. Defaults to Django’s PasswordChangeForm
• success_url: If you’ve created your own custom PasswordChangeDoneView then you’ll need to update this. The default is to use Django’s but unless you have a top level urls.py has the name of password_change_done you’ll get an error.
• title: defaults to ‘Password Change’ and is translated into local language

Example

views.py

class myPasswordChangeView(PasswordChangeView):
    success_url = reverse_lazy('rango:password_change_done_view')

urls.py

path('password_change_view/', views.myPasswordChangeView.as_view(), name='password_change_view'),

password_change_form.html

{% extends "base.html" %}
{% load i18n %}

{% block content %}
    <h1>
    {% block title %}
        {{ title }}
    {% endblock %}
    </h1>
<p>{% trans "Password changed" %}</p>
{% endblock %}

Conclusion

The only thing to keep in mind here is the success_url that will most likely need to be set based on the application you’ve written. If you get an error about not being able to use reverse to find your template, that’s the issue.
