Geodjango Tutorial 2 : Spatial data and Geo-databases

This is the second tutorial in this series that introduces the user on how to develop models to accommodate spatial data and configuration of spatial databases for a Geodjango project.
Unlike other fields within a Django model, GIS models are different in terms of type and design. Explore more options on GIS models in this video.

Hi Wanjohi thanks for the great tutorial series! I'm at the end of tutorial 2 / beginning of tutorial 3 and am trying to modify leaflet. I'm able to see the leaflet map in my admin (the leaflet watermark in lower righthand corner says 'Leaflet | Open StreetMap Contributors. However no matter where I set my center value like you do at beginning of tutorial 3 my center always remains the same. What could the issue be?

If you get a 'TemplateDoesNotExist' after the changes related to Leaflet around 25:00, try to change the order of the import-Statements in admin.py.

For me, it only worked, when the order was like:

from leaflet.admin import LeafletGeoAdmin
from django.contrib import admin
from .models import Incidences

[amandayu]

Thanks for the tutorial. I started from previous tutorial, all worked well. But now I stucked at models of the GeoManager(). When I tried to migrate, return this error: AttributeError: module has no attribute 'GeoManager'. Then when I added 'from django.db.models import Manager as GeoManager' in models.py then I got another error : AttributeError: module 'django.db.models' has no attribute 'PointField'. I have google about this and result is GeoManager has been removed from the latest version of Django. Would you kindly recommend me how to continue practising on your tutorial. Maybe using an earlier version of python and django and which version are they? or what should I use instead of GeoManager(). I am very new in Python and Django. Thanks in advance!
