How to correctly write json structure in models.py of django project using JSONField?

Question

Django

My project database is MongoDB, to connect mongo and django project (using version 4.0.1) I use "djОngo" engine. The database connection is working correctly.
I want to store data in MongoDB that is received from an external API or written through a form on a site page, which can have nested lists, or sometimes nested objects.
An example of a json structure that will be written through the form and come via the API:

"FormsID": 1,
"make": {
      "1_new": 21,
      "2_new": 16,
      "right": 80,
      "left": 10,
      },
   "static": [
      {
         "name": " 1",
         "number": 1,
         "id":93,
         "day": {
            "start": 7,
            "end": 23,}}]

At the moment, the task is partially implemented, I explain. My models.py file:

from djongo import models

class StaticForms(models.Model):
    FormsID=models.ObjectIdField(primary_key=True)
    make = models.JSONField()
    static=models.JSONField()
    day=models.JSONField()

Further, already in the views.py file, I add the necessary keys already in make, static and day.
My views.py file:

from django.views.decorators.csrf import csrf_exempt
from django.http.response import JsonResponse, HttpResponse
from FirstApp.models import StaticForms

@csrf_exempt
def forms_post(request):
    make = {"1_new":request.POST.get("1_new"),
                 "2_new":request.POST.get("2_new"),
                 "right":request.POST.get("right"),
                 "left":request.POST.get("left"),}

    static = {"name":request.POST.get("name"),
                 "number":request.POST.get("number"),
                 "id":request.POST.get("id")}

    day = {"start":request.POST.get("start"),
              "end":request.POST.get("end")}

    post = StaticForms(FormsID=request.POST.get("FormsID"),
                    make=make,
                    static=static,
                    day=day)
    post.save()
    return HttpResponse("Inserted")

After adding data via Postman, I get the following JSON structure. (different from required):

"make": {
      "1_new": 21,
      "2_new": 16,
      "right": 80,
      "left": 10,
      },
   "static": {
         "name": " 1",
         "number": 1,
         "id":93}
   "day": {
         "start": 7,
         "end": 23,}

1) How do I nest the dict "day" inside the dict "static" to get it like in my first example?
2) why is the "FormsID" field missing?
