Want to convert proper JSON request in AXIOS ReactJs to send to django
My payload is in string form as below: payload= "[{"message":"message text", "id":1, "code":0}, {"message":"message text", "id":2, "code":1}, {"message":"message text", "id":3, "code":0}]" I am getting the pay load from query string. ex = https:\xyz.com\endpoint?payload=[{"message":"message text", "id":1, "code":0}, {"message":"message text", "id":2, "code":1}, {"message":"message text", "id":3, "code":0}] JSON.stringify(payload) does not help here as it is a string and JSON.parse(payload) throws error. the axios request is as below: try { const response = await axiosInstance.post('/postenpoint/', payload, { headers: authHeader }); return response; } catch (error) { console.log(error); }; is there any inbuilt function or effective way in JS other than string parsing in such case?

Fetching specific data from SQLite DB to django forms
how do I fetch like specific data I want to a django form. I know how to fetch the entire database to a table by using loops. But I want to fetch specific data according to what user select. At the back of my mind, i know the flow. Eg. Step 1, user choose which data they want to look. Step 2, goes to the table to find the specific data user wants. Step 3: Display it in a html page. I have this table in my web and when user lets say click the edit button for 1st row, it goes to a new html with all its details listed in a table. Eventually i want it to display a form with all the data (2 tables) stored Html: {% extends "interface/base.html" %} {% block footer_scripts %} {{ block.super }} <script> // additional javascript </script> {% endblock footer_scripts %} {% block content %} <div class="content-page"> <div class="content"> <!-- start page title --> <div class="row"> <div class="col-12"> <div class="page-title-box"> <!--<div class="page-title-right"> <ol class="breadcrumb m-0"> <li class="breadcrumb-item"><a href="javascript: void(0);">Hyper</a></li> <li class="breadcrumb-item"><a href="javascript: void(0);">eCommerce</a></li> <li class="breadcrumb-item active">Devices</li> </ol> </div> --> <h4 class="page-title">{{hostname}}</h4> </div> </div> </div> <!-- end page title --> <div class="row"> … -
Django multiple radio input from HTML form with same name
I am having a problem with Django forms. I am currently using the request.POST to validate the POST within views. I want to send inputed-data(radio type) from my template with the same name. In my template.py: <form method="post" action="{% url 'app:AnsSubmission' %}"> {% csrf_token %} {% for i in Exam %} <div class="form-group col-xl-12"> <label>{{ i.question }}</label> <div class="radio"> <label><input type="radio" class="mx-2" name="givenAns" array_column="{{ i.pk }} value="True" required>True</label> </div> <div class="radio"> <label><input type="radio" class="mx-2" name="givenAns" array_column="{{ i.pk }} value="False" required>False</label> </div> </div> {% endfor %} <button type="submit" class="btn btn-primary">Submit</button> </form> And willing to fetch these data in views.py like: givenAns_list = request.POST.getlist('givenAns') for i in givenAns_list: this_givenAns = givenAns_list[i] But the problem here is this radio type input field doesn't take value for the same name(not as a list I wish). If I select answer of 2nd question, the 1st one's selection is unselected. Please suggest how can I fix this? -

Django REST with jwt + regular admin panel
I've setup a basic django app using scaffolding which creates all those nice admin panels for free. I want to expose a REST api so I've followed this tutorial to get it running and add JWT authentication through simplejwt. I have tested my rest auth endpoints, gotten a token and used that token to consume a secured rest endpoint. The problem is -- as soon as I enable this auth scheme, the admin panel stops working. I can't login at all. Which I guess it makes sense considering I've changed the auth paradigm, but it kinda defeats the purpose of the scaffolding to lose all those free admin panels. Is it possible to combine both jwt authentication for my REST services while keeping regular authentication scheme for my admin panel? I want to do a public frontend through REST but keeping my backoffice within the same deployment as the backedn itself. -

ELASTICSEARCH delete is not working when used ELASTICSEARCH_DSL_SIGNAL_PROCESSOR in Celery
I need to do the elasticsearch syncing process Asynchronous. So I override the django-elasticsearch-dsl signal processor with a CelerySignalProcessor. ELASTICSEARCH_DSL_SIGNAL_PROCESSOR = 'core.services.elasticsearch_service.CelerySignalProcessor' Following django-elasticsearch-dsl this documentation, I create a CelerySignalProcessor. from django_elasticsearch_dsl.signals import RealTimeSignalProcessor class CelerySignalProcessor(RealTimeSignalProcessor): def handle_save(self, sender, instance, **kwargs): # create a celery task to do the handle_save task def handle_pre_delete(self, sender, instance, **kwargs): # create a celery task to do the handle_pre_delete task def handle_delete(self, sender, instance, **kwargs): # create a celery task to do the handle_delete task handle_save is working fine in Asynchronous. But handle_pre_delete and handle_delete are not working. When Celery worker would pick up the delete job, the model instance would already deleted. Can anyone give me any idea of how to make the delete process Asynchronous? -

Unable to makemigrations in Django
Problem statement: I am trying to create a new model in a new file - app1/models/model2.py I dont see any error when I try to makemigrations. But Django doesnt detect any changes. If I put the same code in my previous file app1/models/model1.py - makemigrations works. I have tried - python manage.py makemigrations app1 & python manage.py makemigrations My basic model: from django.db import models class Xyz(models.Model): name = models.CharField(max_length=100) I tried through pycharm & normal terminal. I am using UBuntu 20.04LTS. I deleted all migration files then reran makemigrations for app1 , it only picked old changes. did not pick new Xyz model. So perhaps there is something wrong in the way I am creating this new model2.py file. But I am creating it normally like model1.py. I even tried to copy paste and rename the same file. All my folder have init.py in them. -
