urls.py for project:

urlpatterns = [
    url(r'^$', LandingPage.as_view(), name="homepage"),
    url(r'^my_app/', include('my_app.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

When I visit localhost:8000/my_app/password-reset/ I get my landingpage.html template instead. The dev server output definitely shows a single GET to /my_app/password-reset/, and I've checked all the project's apps' urls.py; the password-reset url isn't duplicated anywhere else.

I've even commented out that app's TEMPLATES directory in my settings file to try to force a TemplateDoesNotExist, and it does nothing - the password-reset view seems to be ignoring the template_name parameter that I pass in the url config file.

I'm stumped. What could cause this?
