How to add model Field as 'Self-Referencing Foreign Key' ?

[sbishnu019]

class Category(ormar.Model):
    class Meta(BaseMeta):
        database = database
        metadata = metadata
        tablename = "category"

    name: str = ormar.String(max_length=255)
    parent_category: Optional[Category] = ormar.ForeignKey(to=Category, ondelete='CASCADE')

Scenario

• "Category" Table with fields (name, parent_category).
• parent_category as a ForeignKey pointing to self table

How to achieve this ??????
