Django self-referential foreign key

You can pass in the name of a model as a string to ForeignKey and it will do the right thing.

So:

parent = models.ForeignKey("CategoryModel")

Or you can use the string "self"

parent = models.ForeignKey("self")

python django django-orm

You can use the string 'self' to indicate a self-reference.

class CategoryModel(models.Model):    parent = models.ForeignKey('self')

python django django-orm

class Employee(models.Model):    manager = models.ForeignKey('self', on_delete=models.CASCADE)

class Employee(models.Model):    manager = models.ForeignKey("app.Employee", on_delete=models.CASCADE)
