reverse() and get_absolute_url() may return different output for same FlatPage

[Pat]

>>>
>>> from django.contrib.flatpages.models import FlatPage
>>>
>>> about = FlatPage.objects.get(id=1)
>>>
>>> about
<FlatPage: /about/ -- About>
>>>
>>> about.url
'/about/'
>>>
>>> about.get_absolute_url()
'/about/'
>>>
>>> from django.core.urlresolvers import reverse
>>>
>>> reverse("django.contrib.flatpages.views.flatpage", args=[about.url])
'/page/about/'
>>>

Why reverse() and get_absolute_url() returns two different output and what the purpose behind it ?

I have tested this code in Django 1.8 and 1.10, the same behavior persists.

Can you show me your urls.py file?

I am not sure why flatpages in get_absolute_url are not using "reverse" to get full url address.

I could replace that, add tests - but I need some info if there is some reason to leave it as is.

Closing a ticket as "needsinfo" means the reporter hasn't provided enough information (see ​Closing Tickets). Without some investigation, I'm also not sure how to proceed here however closing the ticket because of that isn't correct.

If a code change isn't practical, we might document the reasons for this.

From what I can tell this is a duplicate of #22261 which was discussed a few years ago. The resolution was that it seemed reasonable to change to use reverse for get_absolute_url. A PR ​https://github.com/django/django/pull/2554 was submitted but never updated after an initial review. If you are looking to move this forward then starting from that PR branch and updating it would be a good start.
