learn_django

This repo will provide an outline for a django project

Django installation in ubuntu

sudo apt install python3-django

Create a project

django-admin startproject {project_name} {dir}

Each project will have following files,

1. {project_name}/ This is the actual Django project package

2. manage.py: Entrypoint of the project which is responsible for managing various aspects of the project

3. settings.py: Contains project specific settings

4. urls.py: Define the url patterns of the project

5. init.py Empty script which indicates the directory as a package

6. wsgi.py Entry point of WSGI(Web Server Gateway Interface) application which is used to deploy the Django proj on production web servers.

7. asgi.py Entry point of ASGI(Asynchronous Server Gateway Interface) application which is used to run the project with asynchronous web servers.

We can create multiple projects using django-admin command. But each project will have the its own settings, database and other project specific configurations

Create a virtual environment for python packages:

virtualenv {virtual_env_name} -p {python_interpreter}

Run the server

python manage.py runserver

Create an app to the existing project

django-admin startapp {app_name}

Then, we need to add app name inside settings.py file under the INSTALLED_APPS to indicate the app is part of the existing project

Create an endpoint

Under views.py script, the logic will be implemented. For example:

# views.py
from django.http import HttpResponse

def home(request):
    return HttpResponse("Welcome")

This function shpould be imported to render the page using an endpoint. To do this, configure the endpoint under urlpatterns

# urls.py

from homw import views

urlpatterns = [
    path('home', views.home)
]
