Description

Hi guys. This is my first bug report so please let me know how I can improve it. I'm still new to the world of GeoDjango, but I did successfully upgrade an existing GeoDjango 1.5 application to 1.6 without any hiccups. I'm only seeing this problem when I create a new projects. This is using the default Django 1.6 project and app structure.

The Problem

The GeoDjango admin for the "world" app created in the GeoDjango tutorial throws a ProgrammingError:

ProgrammingError at /admin/world/worldborder/
column world_worldborder.geom does not exist
LINE 1: ...ld_worldborder"."lon", "world_worldborder"."lat", "world_wor...

Reproduce the problem

  1. Visit the GeoDjango tutorial for Django 1.6 ​https://docs.djangoproject.com/en/1.6/ref/contrib/gis/tutorial/
  1. Create a database with GIS extensions ​https://docs.djangoproject.com/en/1.6/ref/contrib/gis/install/postgis/#creating-a-spatial-database-with-postgis-2-0-and-postgresql-9-1
  1. Create the "world" app described ​https://docs.djangoproject.com/en/1.6/ref/contrib/gis/tutorial/#create-a-new-project
  1. Follow the steps up to Put your data on the map. Run python manage.py runserver .
  1. Visit ​http://127.0.0.1:8000/admin/world/worldborder/ to see the error.

Notes

  • Most of the tutorial works as described. it's only the admin section that throws an error.
  • The output from python manage.py sqlall world is different than the tutorial: 
    BEGIN;
CREATE TABLE "world_worldborder" (
    "id" serial NOT NULL PRIMARY KEY,
    "name" varchar(50) NOT NULL,
    "area" integer NOT NULL,
    "pop2005" integer NOT NULL,
    "fips" varchar(2) NOT NULL,
    "iso2" varchar(2) NOT NULL,
    "iso3" varchar(3) NOT NULL,
    "un" integer NOT NULL,
    "region" integer NOT NULL,
    "subregion" integer NOT NULL,
    "lon" double precision NOT NULL,
    "lat" double precision NOT NULL,
    "mpoly" geometry(MULTIPOLYGON,4326) NOT NULL
)
;
CREATE INDEX "world_worldborder_mpoly_id" ON "world_worldborder" USING GIST ( "mpoly" );

COMMIT;

Thanks for the detailed report, the form is good :-)

I think the problem comes from the difference between models generated with LayerMapping, where the geometric field is (manually) named mpoly and the models generated with ogrinspect where the geometric field is named geom. The model definition should match the method used to produce the database table, being one or the other.

This might deserve a short notice in the tutorial. Also for the sqlall output, the difference depends on the PostGis version used. So we should also add a note. Accepting at least for that documentation issue.

comment:2 by bowenii_clinton@…, 12 years ago

I believe I am running into the same problem; and I apologize if this comment is not of any use this is my first time reporting/commenting on a bug.

Using the same setup as the bug reporter, I get the following from running "python manage.py sqlall world"

BEGIN;
CREATE TABLE "world_worldborder" (

"id" serial NOT NULL PRIMARY KEY,
"name" varchar(50) NOT NULL,
"area" integer NOT NULL,
"pop2005" integer NOT NULL,
"fips" varchar(2) NOT NULL,
"iso2" varchar(2) NOT NULL,
"iso3" varchar(3) NOT NULL,
"un" integer NOT NULL,
"region" integer NOT NULL,
"subregion" integer NOT NULL,
"lon" double precision NOT NULL,
"lat" double precision NOT NULL,
"mpoly" geometry(MULTIPOLYGON,4326) NOT NULL

)

;
CREATE INDEX "world_worldborder_mpoly_id" ON "world_worldborder" USING GIST ( "mpoly" );
COMMIT;

Whis is the same as the bug reporter. So the value GIST_GEOMETRY_OPS is not shown as is shown on ​https://docs.djangoproject.com/en/dev/ref/contrib/gis/tutorial/#introduction

If I am reading this correctly on ​http://trac.osgeo.org/postgis/ticket/1287 , I beleive GIST_GEOMETRY_OPS is not a an operator anymore in POSTGIS version 2.0 and higher. Maybe this is what claudep meant by "the difference depends on the PostGis version used."

Any ideas on what should be done about this?

Yes, some syntax has changed in PostGIS 2. So the documentation should be amended consequently (noting possible difference with PostGIS 2).

Fixed #21547 -- Updated GeoDjango tutorial with PostGIS 2 output

Thanks awilliams at cironline.org for the report.

comment:5 by anonymous, 11 years ago

I remain confused about this error. I get the exact same error following the tutorial using django 1.6 & postgis 2.1.1. Can anyone elaborate on a solution?

I am having the same problem 9 years later. Sorry if this has been fixed, but I am having trouble finding the solution.

I am using POSTGIS 3.0, django 4.2.1.
