Question

Error: One or more models did not validate:
maps.parking: 'layer_id' has a relation with model sdr_layer.Sdr_layer, which has either not been installed or is abstract.

This is the error that I have .

My maps/models.py looks like this 
# This is an auto-generated Django model module created by ogrinspect.
from django.contrib.gis.db import models

class Parking(models.Model):
    layer_id= models.ForeignKey(sdr_layer.Sdr_layer)
    name = models.CharField(max_length=80)
    descriptio = models.CharField(max_length=80)
    geom = models.PointField(srid=4326)
    objects = models.GeoManager()

# Auto-generated `LayerMapping` dictionary for Parking model
parking_mapping = {
    'name' : 'Name',
    'descriptio' : 'Descriptio',
    'geom' : 'POINT25D',
}

Where sdr_layer/models.py looks like this

from django.db import models

    class Sdr_Layer(models.Model):
       layer_name = models.CharField(max_length = 100)
       layer_attribute_name = models.CharField(max_length = 100)

I basically want the Sdr_layer.id to act as the foreign key for the app maps .

Make sure sdr_layer is listed your INSTALLED_APPS in settings.py
