Storing JSON variable in django database - json

Question

In my app that uses Gridster I am changing the widget positions and then saving it as a json variable.I want to store this json variable in django database.
For that I am not understanding how should I define a function in views.py and a class in models.py which can store the json variable
My HTML/JS template is
var URL = "{% url 'my_view_url' %}";
$('.js-seralize-update').on('click', function () {
var s = gridster.serialize();
updated_grid=JSON.stringify(s);
$('#log').val(updated_grid);
function updategridster(){
var data = updated_grid;
$.post(URL, data, function(response){
if(response === 'success'){ alert('Yay!'); }
else{ alert('Error! :('); }
});
}
});
My views.py
def save_grid(request):
if request.method == 'POST':
# Some code to get json variable and store it to model
return HttpResponse('success') # if everything is OK
I want to write some kind of class in models.py corresponding to view.py so that JSON variable can be saved
Edit1
My models.py is
from django.db import models
from django.utils import timezone
from django.utils import simplejson as json
class update_grid(models.Model):
data = JSONField(null=True, blank=True)
I just want to send data from views to this model(If it is correct)
Edit 2
My JS Script is updated as follows
var URL = "{% url 'save-grid' %}";
$('.js-seralize-update').on('click', function () {
var s = gridster.serialize();
updated_grid=JSON.stringify(s);
$('#log').val(updated_grid);
function updategridster(updated_grid){
var data = updated_grid;
$.post(URL, data, function(response){
if(response === 'success'){ alert('Yay!'); }
else{ alert('Error! :('); }
});
}
updategridster(updated_grid);
});
Now I get this error
POST http://localhost:8000/calendar_grid/save-grid net::ERR_CONNECTION_ABORTED jquery.min.js:2

You have the built in JSONField if you use PostgreSQL.
Otherwise there are several implementations like django-jsonfield, for admin i pair this with django-jsoneditor
Then you can save the JSON data in a single field, and in the case of the built in, you can even do queries/filter on specific keys inside the JSON structure.
