How to redirect to another url after sending a POST request to admin:auth_user_password_change in Django?

I'm using the built in django admin site for the application's admin site in a sense that POST requests are built identically to its equivalent admin site, and sent to the same urls. So it's like the application admin site is just a wrapper for the admin site.

My problem is, I don't know how to redirect back to url where it was originally posted. Currently it redirects to the Change User admin page. I'd like it to redirect back to the page.

Here's my change-password-template.html:

<div>
    <form action="{% url 'admin:auth_user_password_change' user.pk %}" method="post" id="change-password-form">
    {% csrf_token %}
    # ... here goes the password fields
    <input type="submit" value="Change password">
        </div>
            <input type="hidden" name="next" value="{% url 'change_password' id=user.pk%}"> # my attempt at trying to redirect back to the original webpage
        </div>
    </form>
</div>

So, it does correctly post to admin/auth/user/{{user.pk}}/password/ but instead of redirecting back to the that page it instead redirects to: admin/auth/user/{{user.pk}}/change/. How can I make it do so?

The wrong way to do it...

You would need to overwrite the user_change_password method in your User admin, since that is where the redirect happens:

# contrib.auth.admin.py

    def user_change_password(self, request, id, form_url=''):
        ...
        if request.method == 'POST':
            form = self.change_password_form(user, request.POST)
            if form.is_valid():
                ...
                return HttpResponseRedirect(
                    reverse(
                        '%s:%s_%s_change' % (
                            self.admin_site.name,
                            user._meta.app_label,
                            user._meta.model_name,
                        ),
                        args=(user.pk,),
                    )
                )

Since this ModelAdmin is registered in the auth app, you will need to unregister that, add your own custom UserAdmin. There are clear instructions on how to do this in the django docs. Once you have done that simply overwrite the method above and edit the redirect.

This would be much more effort than it's worth however, and more importantly it would also be a nasty hack. It's not what the admin interface is intended for. (It would also have the unintended side-effect that when you actually do use the admin app, it will now redirect to wherever you now have told it to - this would be very unusual behaviour).

A better solution...

If you want to add an end-point where a user can change their password it's not difficult to do it yourself, and that would be the best solution in this case.

from django.contrib.auth.models import User
from django.http import HttpResponseRedirect
from django.urls import reverse

def change_password(request, user_id):
    new_password = request.POST["password"]
    user = User.objects.get(id=user_id)
    user.set_password(new_password)
    user.save()
    return HttpResponseRedirect(reverse('your_url_here))

You'll need to add some additional checks (e.g. make sure the user has the appropriate permissions, make sure the request is a POST etc.).

Probably better still...

Django actually has a built in view for doing this, that you can subclass to customise.

# views.py
from django.contrib.auth.views import PasswordChangeView

class MyPasswordChangeView(PasswordChangeView):
    success_url = reverse("url_to_redirect_to")

# urls.py
urlpatters = [
    path('change_password', MyPasswordChangeViews.as_view())
]
