Describe the polymorphic relationship of Django -

tell me how describe connection:

there table in there can different types of records (type1, type2 or type3).

models.py

from django.db import models django.contrib.contenttypes.fields import genericforeignkey, genericrelation django.contrib.contenttypes.models import contenttype  class general(models.model):     field1 = models.charfield(max_length=512, blank=true, null=true)     field2 = models.charfield(max_length=512, blank=true, null=true)     content_type = models.foreignkey(contenttype)     object_id = models.positiveintegerfield()     content_object = genericforeignkey('content_type', 'object_id')      class meta:         db_table = 'general'    class type1(models.model):     name = genericrelation(product)     address = models.charfield(max_length=512, blank=true, null=true)     number = models.charfield(max_length=256, blank=true, null=true)      class meta:         db_table = 'type1' 

how make connection , choose want type in type, example type2?

this looks correct except line:

name = genericrelation(product) 

should be:

name = genericrelation(general) 

in order form correct reverse generic relation.
