How do I resolve GDALException 'OGR failure' when adding spatial points in Django admin?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm developing a Django app using GeoDjango to store spatial point locations, but when I try adding a point through the admin interface, I encounter the following error:

Exception Type:  GDALException
Exception Value: OGR failure.

I installed gdal via pip and from the Python Extension Packages for Windows - Christoph Gohlke resource. I've configured my project as follows:

PYTHON
GDAL_LIBRARY_PATH = "C:/Users/Utente/Desktop/geodjango/v_env/Lib/site-packages/osgeo/gdal304.dll"
GEOS_LIBRARY_PATH = "C:/Users/Utente/Desktop/geodjango/v_env/Lib/site- packages/osgeo/geos_c.dll"

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': 'postgres',
        'USER': 'postgres',
        'PASSWORD': 'postgres',
        'HOST': 'localhost',
        'PORT': '5432',
    },
}

My model in models.py is defined as:

PYTHON
from django.contrib.gis.db import models as spatialmodels
from django.db import models

class SpatialData(models.Model):
    name = models.CharField(max_length=50)
    location = spatialmodels.PointField(srid=4326)

    def __str__(self):
        return self.name
    
    class Meta:
        verbose_name_plural = "Incidences"

The admin configuration in admin.py is:

PYTHON
from django.contrib.gis import admin
from world.models import SpatialData

admin.site.register(SpatialData, admin.GISModelAdmin)

I applied migrations and checked that both GDAL and osgeo import correctly in the Python shell, yet the error persists. Can anyone help me diagnose and resolve this issue?

Troubleshooting GeoDjango GDAL Exception

Based on your error message and configuration, you're encountering a GDALException with the message "OGR failure" when trying to add a point through the Django admin interface. This is a common issue when working with GeoDjango, especially on Windows. Let's troubleshoot this step by step.

Possible Issues and Solutions

1. Library Path Configuration

Your library path configuration has a potential issue. There appears to be a space in the GEOS_LIBRARY_PATH:

PYTHON
GEOS_LIBRARY_PATH = "C:/Users/Utente/Desktop/geodjango/v_env/Lib/site- packages/osgeo/geos_c.dll"
                                                                    ^

This space between "site-" and "packages" could be causing problems. Fix it to:

PYTHON
GEOS_LIBRARY_PATH = "C:/Users/Utente/Desktop/geodjango/v_env/Lib/site-packages/osgeo/geos_c.dll"

2. GDAL Version Compatibility

You're using gdal304.dll which indicates GDAL 3.0.4. Make sure this version is compatible with your Django version. For Django 5.1, GDAL 3.4.x or newer is recommended.

3. Admin Configuration

Try using OSMGeoAdmin instead of GISModelAdmin for better OpenLayers integration:

PYTHON
from django.contrib.gis import admin
from world.models import SpatialData

admin.site.register(SpatialData, admin.OSMGeoAdmin)

4. Verify Library Loading

Add this code to your Django shell to verify that GDAL is loading correctly:

PYTHON
from django.contrib.gis.gdal import gdal_version
print(gdal_version())

5. Environment Variables

Sometimes setting environment variables can help. Add these to your system environment variables:

GDAL_DATA=C:/Users/Utente/Desktop/geodjango/v_env/Lib/site-packages/osgeo/data/gdal
PROJ_LIB=C:/Users/Utente/Desktop/geodjango/v_env/Lib/site-packages/osgeo/data/proj

6. PostGIS Configuration

Ensure that PostGIS is properly installed and configured in your PostgreSQL database. You can verify this by running:

SQL
SELECT PostGIS_version();

in your PostgreSQL client.

Recommended Steps

Fix the space in your GEOS_LIBRARY_PATH
Verify GDAL is loading correctly using the Django shell
Set the environment variables
Try using OSMGeoAdmin instead of GISModelAdmin
Check your PostGIS installation

If the issue persists, try to get more detailed error information by adding the following to your settings.py:

PYTHON
DEBUG = True
LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
            'level': 'DEBUG',
        },
    },
}

This will provide more detailed error messages that might help identify the specific issue with GDAL.
