Update value in database

[Nuno Vieira]

Hi!

I have a real estate django app and i have a form to users insert a new 
property. I also have in the form several images fields that users can use 
to upload images to database whitout problem. 
The problem is if the *user want to delete one of the images field.*

I have an ajax request that sends the id of the property and the field name 
to update (delete) on database.

function delete_img(i){
              var prim_key = document.getElementById('list_id').value;
              var id_number = i.id;

               $.ajax({
                  type: 'GET',
                  url: '',
                  data: {'csrfmiddlewaretoken' : "{{  csrf_token  }}",
'img_id':id_number , 'post_id':prim_key },
                  success: function(data){
                      if(data) {
                       console.log(id_number + " " + prim_key);
                       document.getElementById('img_' + id_number).src = 
"http://localhost:8000/media/upload_img_default.png";;
                      }
           
     
                    }
                });

In views.py i have a function that receives the data from ajax and executes 
the task.

@csrf_exempt
def delete_img(request):
        if request.method=='GET' and request.is_ajax():
            img_id = request.GET['img_id']
            post_id = request.GET['post_id']
            try:
                obj = Listing.objects.get(id=post_id)
                obj1 = getattr(obj,img_id) 
                obj1.value = None
                obj.save()
                return True
            except Listing.DoesNotExist:
                return False
        else:
            return False


Can anyone help me with this situation?
Thanks for your help.
