Usage

a) declare concrete datamodel:

# app/models.py
from django.db import models
from djfim.models import Blob, Entity, Generation

class MyBlob(Blob):
    class Meta:
        abstract = False

class MyEntity(Entity):
    generation = models.ForeignKey('MyGeneration', on_delete=models.CASCADE, null=False)
    blob = models.ForeignKey('MyBlob', on_delete=models.CASCADE, null=False)

    class Meta:
        abstract = False

class MyGeneration(Generation):
    l_anchor = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, related_name='l_subtree')
    r_anchor = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, related_name='r_subtree')

    class Meta:
        abstract = False

b) migrate datamodel:

python manage.py makemigrations
pythno manage.py migrate

c) setup datamodel reference:

# project/settings.py
DJFIM = {
    'MODLE': {
        'BLOB': {
            'app_name': 'app',
            'app_label': 'MyBlob',
        },
    }
}

d) invoke management command:

python manage.py fim [action]
