INSTALLED_APPS = [
    'appName1',
    'appName2',
    'appName3',
]

Example –

    'signup',
]

Django App Directory Structure

If you create a Django app named signup inside the root directory of codingstatus project. The you will get the following directory structure –

myproject
  |__myproject

  |     |      |__ __init__.py
  |     |__ __init__.py

Here, we will discuss only the folder structure of created app named signup one by one in details –

By default, This folder is considered a python package due to containing the _init.py file.

Also, all the migration files will be created in this folder while you run the makemigration command

admin.py

In this file, You will have to register models that contains information about database tables & their fields.

A model contains the information of database tables and their fields & attributes

Steps to Create Django App

Here, I will create Django App using command line terminal on the windows. If you have linux & mac then you can also use the given command line & these steps.

But you have to use starting default command according to your operating system. for example – if you are using linex then you will have to use sudo before provide command by me

Now, You can follow these steps to create a Django App inside a root directory quickly

1. Open Command line Terminal

First of all, you have to open command line terminal and go into your project folder.

Here , I have created a project folder named djangoproject in D drive of my systm. So, I have opened command with these path

D:\> djangoproject

2. Create a Django Project

then run this command to create Django project with the name of codingstatus –

D:\> djangoproject>django-admin startproject codingstatus

3. Go to Root Project Directory

Now, you have to into root directory of the created Django project by running this command –

D:\> djangoproject>cd codingstatus

then you will move to project folder codingstatus

D:\> djangoproject>codingstatus>

4. Run manage.py startup appName

After that, run command manage.py startup appName. But You have to put your own app name in place of appName.

Suppose you have to create multiple app like signup, login, faculty, student, attendence, course, fees, exam, & result. But you have to run command one by one for each app.

D:\> djangoproject>codingstatus>python manage.py startapp signup
D:\> djangoproject>codingstatus>python manage.py startapp login
D:\> djangoproject>codingstatus>python manage.py startapp faculty
D:\> djangoproject>codingstatus>python manage.py startapp student
D:\> djangoproject>codingstatus>python manage.py startapp attendence
D:\> djangoproject>codingstatus>python manage.py startapp course
D:\> djangoproject>codingstatus>python manage.py startapp fees
D:\> djangoproject>codingstatus>python manage.py startapp exam
D:\> djangoproject>codingstatus>python manage.py startapp result

After running the above commands, you will get the created app folders in the root directory of codingstatus.

5. Register Django App in Settings.py

At last, resgister all the created apps within INSTALLED_APPS=[ ] array in settings.py file of inner project folder of codinstatus –

INSTALLED_APPS = [
    'signup',
    'login',
    'faculty',
    'student',
