It seems that if I define a model with Meta.abstract=True then any indexes
I define in that model are not propgated to subclasses.
Example:
{{{
class CustomBase(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField(max_length=100)
class Meta:
abstract = True
indexes = [
models.Index(fields=['name'], name='name_idx')
]
class CustomSub(CustomBase):
ip_address = models.GenericIPAddressField()
class Meta:
indexes = [
models.Index(fields=['ip_address'], name='ip_address')
]
}}}
Then
{{{
>> python manage.py makemigrations
- Create model CustomSub
- Create index ip_address on field(s) ip_address of model customsub
}}}
No mention of index 'name_idx' from the base class
