djongo Company with ID “None” doesn’t exist. Perhaps it was deleted?-CodePudding

I couldn't find a solution among similar questions.

Using mongosh, the Company objects do exist, but in the admin, they show as object(None) and therefore cannot be edited due to error "Company with ID “None” doesn’t exist. Perhaps it was deleted?". I guess it is about the "id" detection, but can not fix it myself. Question: how to fix the code to make the Company object to be shown correctly, not as None.

myproject> db.companies_company.find()
[
  { _id: ObjectId("6145dd9a8bc9a685b2ae2375"), name: 'company1' },
  { _id: ObjectId("6145ddaa8bc9a685b2ae2377"), name: 'company2' }
]

models.py:

from django.db import models

# Create your models here.
class Company(models.Model):
    name = models.CharField(max_length=100, blank=False, null=False, unique=True)

admin.py:

from django.contrib import admin

# Register your models here.
from .models import Company

@admin.register(Company)
class CompanyAdmin(admin.ModelAdmin):
    pass

The manual setting of the _id field solved the issue.

from djongo import models

# Create your models here.
class Company(models.Model):
    _id = models.ObjectIdField()
    name = models.CharField(max_length=100, blank=False, null=False, unique=True)
