PointField() Not Working correctly in GeoDjango

Question

I have GDAL (using homebrew) and SQLite installed. I would like to create a teacher with a PointField() which stores long and lat values, to know their location. Later I plan on adding the ability to search by distance using something like:

Teacher.objects.filter(location__distance_lte=(your_location,D(m=distance))).distance(your_location).order_by('distance')

models.py

from django.db import models
from django.contrib.gis.db import models as gis_models
from django.contrib.auth.models import User

class Teacher(models.Model):
    user = models.ForeignKey(User, unique=True)
    location = gis_models.PointField()
    availability = models.BooleanField(default=False)

However, when I run the server, I get the following error:

Unhandled exception in thread started by <function
check_errors.<locals>.wrapper at 0x111c619d8>

did you look for the same trouble? https://stackoverflow.com/questions/18643998/geodjango-geosexception-error and the ticket https://code.djangoproject.com/ticket/28441 ? — Brown Bear, Aug 18 '17 at 17:26

This is a known issue, which has been fixed and will be rolled out in Django v1.11.5.

If you can't wait for 1.11.5 or don't want to run on the dev branch, you can go to a previous version of geos:

brew switch geos 3.6.1

Thanks, I get: Error: geos does not have a version "3.6.1" in the Cellar. – Roma Aug 18 '17 at 17:59
