26155	Skip URL checks if settings.ROOTURL_CONF isn't defined	Buddy Lindsey	Buddy Lindsey	"If you try to create a migration with `makemigrations` it throws an error (below) because it is running the `check_url_config` system check. There currently isn't a way to disable this check, and the use case we have we don't need/use urls.

Here are the steps to reproduce this error:

{{{
./manage.py startproject demo
cd blog
vim blog/settings.py    # comment out ROOT_URLCONF
./manage.py startapp blog
vim blog/models.py    # add model below
./manage.py makemigrations
}}}

{{{#!python
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=, blank=True)
    description = models.TextField(blank=True)
}}}

That should be enough to reproduce the error.

My thought is we need to add a way to disable the `check_url_config` check."	Bug	closed	Core (System checks)	1.9	Normal	fixed			Accepted	0	0	0	0	0	0
