Making app –

From the above list, we can see that brand itself can be a different table in the database. For user’s comfort, Django itself provides SQLite3 database which we will be using during this series. During deployment, we can use a different database. To read more about databases, check out DataBase Management System.
To create an app for brand, run the following command in your terminal

python manage.py startapp brand

Now, brand folder should look like

What these files are?

__init__.py: This is a python package.
admin.py: In python file, we will write code which will be relevant to admin.
models.py: In this python file, we will write code which will be revolving around database handling.
tests.py: In this python file, we can write test codes to test if changes done in our code is working fine or not before including them in our main code.
views.py: In this python file, we will write what should user view on a webpage as name of file suggests.
Migrations: It is a folder which will store all the changes that we will make in database. Initially, it is empty as it contains only __init__.py of its own and we haven’t interacted with database yet.

Now, goto geeks_site/settings.py and in INSTALLED_APPS, add brand in it. It will integrate brand app to your project geeks_site.
