first of all, you can remove the 1. id (pK) line. django already create this field for you in background. I think you want to reference id field of A table to himself; it is known as recursive relationship. Speaking the which, you can use:

models.ForeignKey('self', on_delete=models.CASCADE)

I have table A with my following fields:
1. id (PK)
2. fname (text)
3. name (text)
4. A_id (integer)

I have problem with 4th field, Because it has to refrenced to id
field. I can't implement it into Django.

How can I write model class for above table in models.py ?
