Creating an application in a Django project involves several steps, starting from setting up the environment, creating the project and application, and finally to run it.
1. Install Python and Django: Django applications run on Python, so you need to have Python installed, preferably Python3. You can download Python from the official Python website (https://www.python.org/). After installing Python, you can easily install Django using pip, which is a package manager for Python. To install Django, you should open your terminal and run the command `pip install django`.
1. Create a Django project: After successfully installing Django, navigate to the directory where you want to create the project. Then run this command `django-admin startproject [projectname]` replacing the `[projectname]` with the desired name of your project. Django will create a new directory with the same name as your project name, where all the project files will reside.
1. Create a Django application: Go into your project directory using the terminal and run this command `python manage.py startapp [appname]`, replacing `[appname]` with the name of application. Django will create a new directory in your project with the name of your application. Your application will be a sub-directory of your project having its own set of files including `models.py`, `views.py`, `apps.py`, and more.
1. Configure your application: Now, you need to tell Django that you have created an application. Open `settings.py` located in the project directory, search for `INSTALLED_APPS`, and add the name of your application to this list. Django uses this configuration to include your application when it runs.
1. Create views: Open `views.py` in your app directory and create a simple view. A view is a Python function that takes a web request and returns a web response.
For example:
```
from django.http import HttpResponse
def home(request):
return HttpResponse(‘Hello, World!’)
```
1. Connect views to urls: Now, you need to tell Django when to serve this view. In your app directory, create a new file named `urls.py`, then write this code into the file:
```
from django.urls import path
from . import views
urlpatterns = [
path(‘’, views.home, name=‘home’),
]
```
You also need to connect your app’s urls to your project’s urls. In your project’s `urls.py`, include this code:
```
from django.urls import include, path
urlpatterns = [
path(‘’, include(‘[appname].urls’)),
…
]
```
1. Run Django server: You’re ready to run the server now. Run this command on the terminal `python manage.py runserver`. If everything is okay, Django will start the server at `localhost:8000` or `127.0.0.1:8000`. Open a web browser, and visit `localhost:8000` to see your application running.
These procedures are well documented in the official Django documentation (https://docs.djangoproject.com/en/3.2/).
These steps provided an overview of how to create an application in a Django project. There’s a lot more you can do with Django such as working with databases, handling user authentication, and deploying your application to a live server. These would involve more detailed study and practice.
