How to Create Json File in Django?

Hi Dev,

This article is focused on django create json file example. This article will give you simple example of how to create json file using django. I explained simply step by step how do i serve a json file from django. you can understand a concept of django create and output json file from view.

There are several ways to create text file in django. we will use HttpResponse and pass the argument content_type='application/json'. so let's see the below examples.

You can use these examples with django3 (django 3) version.

let's see below simple example with output:

In this step, we’ll create a new django project using the django-admin. Head back to your command-line interface and run the following command:

django-admin startproject example

python3 manage.py startapp core

Here, do not forget to register the new app in the settings.py file. Under installed apps, just add ‘core’ to the list:

....
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'core',
]

In this step, we need to create the views for performing ajax image upload to the database.Open the core/views.py file and add.

from django.shortcuts import render
from django.http import HttpResponse

def writetofile(request):
    filename = "demo.json"
    to_json = {
        "name": "Bhavesh",
        "age": "25"
    }
    response = HttpResponse(json.dumps(to_json), content_type='application/json')
    response['Content-Disposition'] = 'attachment; filename={0}'.format(filename)
    return response

In this section, we’ll create the urls to access our views.Go to the urls.py core/urls.py file and update it as follows:

from django.urls import path
from . import views

urlpatterns = [
    path('json/', views.writetofile)
]

Next, we will require the modify the urls.py your root preoject folder lets update the file.

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('core.urls'),
]

In this step, we’ll run the local development server for playing with our app without deploying it to the web.

python manage.py runserver

Next, go to the address with a web browser.

http://localhost:8000/json/

I Hope It will help you....
