limit_choices_to=function() not work in python-3.6+django-1.11.2

[Drunkard Zhang]

Hi, fellows:

I was running python-3.4+django-1.9.13 previous, and upgrading to python-3.6+django-1.11.2, while testing, I found that my limit_choices_to function not working now, here's detail.

I'm using a middleware to get current user who is accessing my site, and use it in limit_choices_to function, to provide different filter based on current user. This works great with python-3.4 + django-1.9.13; and using django-crispy-forms to render user forms.

After upgraded to python-3.6+django-1.11, limit_choices_to function didn't called when I opened a USER EDIT FORM (by adding print() to the function), but it still works with django admin.

So the question is:
1. The difference of init procedures between django 1.9.13 and 1.11.2? Because 1.9.13 won't exec limit_choices_to function on init, while 1.11.2 does.
2. Where should I fix the problem? django init settings, my form, or even django-crispy-forms?

To get some insight, I'd try bisecting to find the Django commit where the behavior changed:

After a whole day digging that, I found the commit changed the behaviour: 6abd6c598ea23e0a962c87b0075aa2f79f9ead36, and the ticket: https://code.djangoproject.com/ticket/27563

I'm feeding back to upstream.

Should I open a new regression report for this?

A new ticket is appropriate since the changes for the original ticket are already released. Please include more explicit steps about how to reproduce the issue -- it's difficult for me to tell exactly what the issue is from the details you provided so far.
