Django CRUD with MySQL overview

We will build Rest Apis using Django Rest Framework that can create, retrieve, update, delete and find Tutorials by title or published status.

First, we setup Django Project with a MySQL Client. Next, we create Rest Api app, add it with Django Rest Framework to the project. Next, we define data model and migrate it to the database. Then we write API Views and define Routes for handling all CRUD operations (including custom finder).

The following table shows overview of the Rest APIs that will be exported:

Methods Urls Actions
GET api/tutorials get all Tutorials
GET api/tutorials/:id get Tutorial by id
POST api/tutorials add new Tutorial
PUT api/tutorials/:id update Tutorial by id
DELETE api/tutorials/:id remove Tutorial by id
DELETE api/tutorials remove all Tutorials
GET api/tutorials/published find all published Tutorials
GET api/tutorials?title=[kw] find all Tutorials which title contains 'kw'

Finally, we’re gonna test the Rest Apis using Postman.


Let’s look at the diagram below, it shows the architecture of our Django CRUD Rest Apis App with MySQL database:


  • HTTP requests will be matched by Url Patterns and passed to the Views
  • Views processes the HTTP requests and returns HTTP responses (with the help of Serializer)
  • Serializer serializes/deserializes data model objects
  • Models contains essential fields and behaviors for CRUD Operations with MySQL Database


  • Python 3.7
  • Django 2.1.15
  • Django Rest Framework 3.11.0
  • PyMySQL 0.9.3
  • django-cors-headers 3.2.1

Project structure

This is our project structure:


Let me explain it briefly.

  • tutorials/ declares TutorialsConfig class (subclass of django.apps.AppConfig) that represents Rest CRUD Apis app and its configuration.
  • bzkRestApisMySQL/ contains settings for our Django project: MySQL Database engine, INSTALLED_APPS list with Django REST framework, Tutorials Application, CORS and MIDDLEWARE.
  • tutorials/ defines Tutorial data model class (subclass of django.db.models.Model).
  • migrations/ is created when we make migrations for the data model, and will be used for generating MySQL database table.
  • tutorials/ manages serialization and deserialization with TutorialSerializer class (subclass of rest_framework.serializers.ModelSerializer).
  • tutorials/ contains functions to process HTTP requests and produce HTTP responses (using TutorialSerializer).
  • tutorials/ defines URL patterns along with request functions in the Views.
  • bzkRestApisMySQL/ also has URL patterns that includes tutorials.urls, it is the root URL configurations.

Install Django REST framework

Django REST framework helps us to build RESTful Web Services flexibly.

To install this package, run command:
pip install djangorestframework

Setup new Django project

Let’s create a new Django project with command:
django-admin startproject bzkRestApisMySQL

When the process is done, you can see folder tree like this:


Now we open and add Django REST framework to the INSTALLED_APPS array here.

    # Django REST framework 

Connect Django project to MySQL

We need a MySQL Client to work with MySQL database.
In this tutorial, we’re gonna use pymysql.

Run the command to install it: pip install pymysql.
Then open and write following code to import pymysql to our Django project:

import pymysql

We also need to setup MySQL Database engine.
So open and change declaration of DATABASES:

    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'testdb',
        'USER': 'root',
        'PASSWORD': '123456',
        'HOST': '',
        'PORT': '3306',

Setup new Django app for Rest CRUD Api

Run following commands to create new Django app tutorials:

cd bzkRestApisMySQL
python startapp tutorials

Refresh the project directory tree, you can see it now looks like:


Now open tutorials/, you can see TutorialsConfig class (subclass of django.apps.AppConfig).
This represents the Django app that we’ve just created with its configuration:

from django.apps import AppConfig

class TutorialsConfig(AppConfig):
    name = 'tutorials'

Don’t forget to add this app to INSTALLED_APPS array in

    # Tutorials application 

Configure CORS

We need to allow requests to our Django application from other origins.
In this example, we’re gonna configure CORS to accept requests from localhost:8081.

First, install the django-cors-headers library:
pip install django-cors-headers

In, add configuration for CORS:

    # CORS

You also need to add a middleware class to listen in on responses:

    # CORS

Note: CorsMiddleware should be placed as high as possible, especially before any middleware that can generate responses such as CommonMiddleware.


  • CORS_ORIGIN_ALLOW_ALL: If True, all origins will be accepted (not use the whitelist below). Defaults to False.
  • CORS_ORIGIN_WHITELIST: List of origins that are authorized to make cross-site HTTP requests. Defaults to [].

Define the Django Model

Open tutorials/, add Tutorial class as subclass of django.db.models.Model.
There are 3 fields: title, description, published.

from django.db import models

class Tutorial(models.Model):
    title = models.CharField(max_length=70, blank=False, default='')
    description = models.CharField(max_length=200,blank=False, default='')
    published = models.BooleanField(default=False)

Each field is specified as a class attribute, and each attribute maps to a database column.
id field is added automatically.

Migrate Data Model to the database

Run the Python script: python makemigrations tutorials.

The console will show:

Migrations for 'tutorials':
    - Create model Tutorial

Refresh the workspace, you can see new file tutorials/migrations/
It includes code to create Tutorial data model:

# Generated by Django 2.1.15

from django.db import migrations, models

class Migration(migrations.Migration):

    initial = True

    dependencies = [

    operations = [
                ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
                ('title', models.CharField(default='', max_length=70)),
                ('description', models.CharField(default='', max_length=200)),
                ('published', models.BooleanField(default=False)),

The generated code defines Migration class (subclass of the django.db.migrations.Migration).
It has operations array that contains operation for creating Customer model table: migrations.CreateModel().

The call to this will create a new model in the project history and a corresponding table in the database to match it.

To apply the generated migration above, run the following Python script:
python migrate tutorials

The console will show:

Operations to perform:
  Apply all migrations: tutorials
Running migrations:
  Applying tutorials.0001_initial... OK

At this time, you can see that a table for Tutorial model was generated automatically with the name: tutorials_tutorial:


Create Serializer class for Data Model

Let’s create TutorialSerializer class that will manage serialization and deserialization from JSON.

It inherit from rest_framework.serializers.ModelSerializer superclass which automatically populates a set of fields and default validators. We need to specify the model class here.


from rest_framework import serializers 
from tutorials.models import Tutorial
class TutorialSerializer(serializers.ModelSerializer):
    class Meta:
        model = Tutorial
        fields = ('id',

In the inner class Meta, we declare 2 attributes:

  • model: the model for Serializer
  • fields: a tuple of field names to be included in the serialization

Define Routes to Views functions

When a client sends request for an endpoint using HTTP request (GET, POST, PUT, DELETE), we need to determine how the server will response by defining the routes.

These are our routes:

  • /api/tutorials: GET, POST, DELETE
  • /api/tutorials/:id: GET, PUT, DELETE
  • /api/tutorials/published: GET

Create a inside tutorials app with urlpatterns containing urls to be matched with request functions in the

from django.conf.urls import url 
from tutorials import views 
urlpatterns = [ 
    url(r'^api/tutorials$', views.tutorial_list),
    url(r'^api/tutorials/(?P<pk>[0-9]+)$', views.tutorial_detail),
    url(r'^api/tutorials/published$', views.tutorial_list_published)

Don’t forget to include this URL patterns in root URL configurations.
Open bzkRestApisMySQL/ and modify the content with the following code:

from django.conf.urls import url, include 
urlpatterns = [ 
    url(r'^', include('tutorials.urls')),

Write API Views

We’re gonna create these API functions for CRUD Operations:
tutorial_list(): GET list of tutorials, POST a new tutorial, DELETE all tutorials
tutorial_detail(): GET / PUT / DELETE tutorial by ‘id’
tutorial_list_published(): GET all published tutorials

Open tutorials/ and write following code:

from django.shortcuts import render

from django.http.response import JsonResponse
from rest_framework.parsers import JSONParser 
from rest_framework import status
from tutorials.models import Tutorial
from tutorials.serializers import TutorialSerializer
from rest_framework.decorators import api_view

@api_view(['GET', 'POST', 'DELETE'])
def tutorial_list(request):
    # GET list of tutorials, POST a new tutorial, DELETE all tutorials
@api_view(['GET', 'PUT', 'DELETE'])
def tutorial_detail(request, pk):
    # find tutorial by pk (id)
        tutorial = Tutorial.objects.get(pk=pk) 
    except Tutorial.DoesNotExist: 
        return JsonResponse({'message': 'The tutorial does not exist'}, status=status.HTTP_404_NOT_FOUND) 
    # GET / PUT / DELETE tutorial
def tutorial_list_published(request):
    # GET all published tutorials

Let’s implement these functions.

Create a new object

Create and Save a new Tutorial:

@api_view(['GET', 'POST', 'DELETE'])
def tutorial_list(request):
    elif request.method == 'POST':
        tutorial_data = JSONParser().parse(request)
        tutorial_serializer = TutorialSerializer(data=tutorial_data)
        if tutorial_serializer.is_valid():
            return JsonResponse(, status=status.HTTP_201_CREATED) 
        return JsonResponse(tutorial_serializer.errors, status=status.HTTP_400_BAD_REQUEST)

Retrieve objects (with condition)

Retrieve all Tutorials/ find by title from MySQL database:

@api_view(['GET', 'POST', 'DELETE'])
def tutorial_list(request):
    if request.method == 'GET':
        tutorials = Tutorial.objects.all()
        title = request.GET.get('title', None)
        if title is not None:
            tutorials = tutorials.filter(title__icontains=title)
        tutorials_serializer = TutorialSerializer(tutorials, many=True)
        return JsonResponse(, safe=False)
        # 'safe=False' for objects serialization

Retrieve a single object

Find a single Tutorial with an id:

@api_view(['GET', 'PUT', 'DELETE'])
def tutorial_detail(request, pk):
    # ... tutorial = Tutorial.objects.get(pk=pk)
    if request.method == 'GET': 
        tutorial_serializer = TutorialSerializer(tutorial) 
        return JsonResponse( 

Update an object

Update a Tutorial by the id in the request:

@api_view(['GET', 'PUT', 'DELETE'])
def tutorial_detail(request, pk):
    # ... tutorial = Tutorial.objects.get(pk=pk)
    # ...
    elif request.method == 'PUT': 
        tutorial_data = JSONParser().parse(request) 
        tutorial_serializer = TutorialSerializer(tutorial, data=tutorial_data) 
        if tutorial_serializer.is_valid(): 
            return JsonResponse( 
        return JsonResponse(tutorial_serializer.errors, status=status.HTTP_400_BAD_REQUEST) 

Delete an object

Delete a Tutorial with the specified id:

@api_view(['GET', 'PUT', 'DELETE'])
def tutorial_detail(request, pk):
    # ... tutorial = Tutorial.objects.get(pk=pk)
    # ...
    elif request.method == 'DELETE': 
        return JsonResponse({'message': 'Tutorial was deleted successfully!'}, status=status.HTTP_204_NO_CONTENT)

Delete all objects

Delete all Tutorials from the database:

@api_view(['GET', 'POST', 'DELETE'])
def tutorial_list(request):
    # ...
    elif request.method == 'DELETE':
        count = Tutorial.objects.all().delete()
        return JsonResponse({'message': '{} Tutorials were deleted successfully!'.format(count[0])}, status=status.HTTP_204_NO_CONTENT)

Find all objects by condition

Find all Tutorials with published = True:

def tutorial_list_published(request):
    tutorials = Tutorial.objects.filter(published=True)
    if request.method == 'GET': 
        tutorials_serializer = TutorialSerializer(tutorials, many=True)
        return JsonResponse(, safe=False)

Test the CRUD with APIs

Run our Django Project with command: python runserver 8080.
The console shows:

Performing system checks...

System check identified no issues (0 silenced).

Quit the server with CTRL-BREAK.

Using Postman, we’re gonna test all the Apis above.

  1. Create a new Tutorial using POST /tutorials Api

  2. django-mysql-crud-rest-framework-example-create

  3. Retrieve all Tutorials using GET /tutorials Api

  4. django-mysql-crud-rest-framework-example-retrieve

  5. Update a Tutorial using PUT /tutorials/:id Api

  6. django-mysql-crud-rest-framework-example-update

    Check tutorials_tutorial table after some rows were updated:


  7. Retrieve a single Tutorial by id using GET /tutorials/:id Api

  8. django-mysql-crud-rest-framework-example-retrieve-one

  9. Find all Tutorials which title contains ‘ud’: GET /tutorials?title=ud

  10. django-mysql-crud-rest-framework-example-find-by-title

  11. Find all published Tutorials using GET /tutorials/published Api

  12. django-mysql-crud-rest-framework-example-find-published

  13. Delete a Tutorial using DELETE /tutorials/:id Api

  14. django-mysql-crud-rest-framework-example-delete-one

    Tutorial with id=4 was removed from tutorials table:


  15. Delete all Tutorials using DELETE /tutorials Api

  16. django-mysql-crud-rest-framework-example-delete-all

You can use the Simple HTTP Client using Axios to check it.

  2. can you anyone pls explain about resp api framework django, i am not clear about the rest api,
    i think myself rest api work on http respone , so rest framework works on local server what we connected from that we can used our crud operation or someother thing —– is that correct about rest framework what i explained above

  3. Hi, really nice demo. I have the following questions:

    1. Where are the HTML templates for nice forms in this project, i dont see them.
    2. What IDE did you use. It seems simple and elegant.

    1. Hi Obert,

      1. The UI template is built with Angular/React/Vue Client that I mention in the tutorial.
      2. I use Eclipse IDE 🙂

      1. Thanks hey. When i downloaded the source code from github. The templates where not there. It would have been nice had u included them as well in the project source code. If you could consider this the better even as part of this tutorial such that there will be no loose ends for someone learning
