Re: Invalid pk \"1\" - object does not exist.

Hello,

What if you use kind of the following as json data:

nb: The following model is a simplified version with only two fields (name and manager which is a FK to itself such as in yours).

[

  {

    "model": "YourApp.YourModelName",

    "pk": 1,

    "fields": {

      "name": "toto",

      "manager": null

    }

  },

  {

    "model": "YourApp.YourModelName",

    "pk": 2,

    "fields": {

      "name": "tata",

      "manager": 1

    }

  }

]

In that case you ensure that a manager object with pk equals to 1 already exists and therefore can be referred to .

'Hope it helps.

{"manager":["Invalid pk \"1\" - object does not exist."]}

    MANAGER = 'MGR'
    STANDARD = 'STD'


    EMPLOYEE_TYPES = (

        (MANAGER, 'manager'),
        (STANDARD, 'employee')

    )


    role = models.CharField(max_length=25, choices=EMPLOYEE_TYPES)
    name = models.CharField(max_length=100, null=True, blank=True)
    employee_id = models.CharField(max_length=100, null=True, blank=True)
    manager = models.ForeignKey('self', null=True, related_name='employee',on_delete=models.CASCADE)

{
  "role":"MGR",
  "name":"John",
  "employee_id" :"IN",
  "manager":1
