Connecting Django App with MySql database on Windows

Connecting Django app with MySQL database on Windows is the basic step in building a MySQL based website in Django. In this post, we will see how we can connect mysql database with Django.

I assume that you have already Django installed inside the Python Virtual environment. If not, you can review this link.

Creating the Django Project

Before we connect mysql database with django app, we need to create a new django project using the django-admin utility.

Open the windows command prompt and type workon django-project to enter your python virtual environment. Now run django-admin startproject hrm. Here, “hrm” is the project name and could be anything of your choice. Now cd into your project folder and run py manage.py runserver. You should see something like below:

Django Server starting

If you focus carefully on above image, it is saying that the django built-in server (good enough for testing and development phase) has started on http://127.0.0.1:8000. If you browse the same URL, you should see django welcome page. Also, in the same image you can see that we have been informed about the pending migrations.

All modern web development frameworks support migrations. With migrations, we can avoid creating tables and schema using mysql commands. Instead, we can define the table structures and relations using the programming language syntax. In short, Migration migrates the structure and relations written in programming language syntax into the database.

Configuring MySQL database with Django

In order to connect mysql database with django app,We need to install MySQL python client into virtual environment. Run pip install mysqlclient. If the server is still running, you need to Ctrl + C before installing any python package.

Chances are high that pip install mysqlclient results in error on windows. If this is the case with you as well, you should consider installing it through a wheel. Some useful wheels are found here. Once you have downloaded the required wheel file, just run following command while still in the virtual environment:
pip install D:\downloads\mysqlclient-1.4.6-c p38-cp38-win32.whl

To verify the installation of the mysqlclient package, run pip freeze. You should see a list of packages installed within your virtual environment and mysqlclient should be one of them.

While SQLite is default, Django officially supports multiple databases out of the box. I assume that you have XAMPP setup on your PC. if not, you can use any method to create mysql database for this tutorial.

We have the project setup now. We now have to configure MySQL with django application using the settings.py file.

Find and comment the below code block in your settings.py file:

Now add the below code block to tell Django that you will indeed use MySQL and not SQLite.

At this point, we have installed mysqlclient and configured the database information in settings.py file. We will now run the migration, which will create and populate all the tables in the database automatically. Following two commands will run the migration:
py manage.py makemigrations
py manage.py migrate

It should be noted here that we should always be inside the project folder (in command prompt) to run any of the manage.py commands.

This is all we need to connect mysql with django app. Share your thoughts in the comment section below.
