We have already covered how to start with Django 1.9. In this article, we will see how to quickly get a simple page running using Django 2.2.
Create a virtual environment using python3.
virtualenv -p /use/bin/python3.5 venv
Activate the virtual environment.
Now install the Django2.2 inside this virtual environment using pip.
pip install Django==2.2
Once Django has been installed, run the
django-admin command to start a project.
Create your project.
$ django-admin startproject helloworld
Go inside the newly created project directory.
$ cd helloworld
You will see a file manage.py and a directory with the same name as of your project.
Create an app here. Every project consists of one or more apps. These are plug-able modules that can be reused in another project if written properly.
$ python manage.py startapp hw
Go inside hw directory. create a new file urls.py.
Add the below lines to this file and save it.
from django.urls import path from . import views app_name = "hw" urlpatterns = [ path(r'', views.home, name='home'), ]
Open views.py file and save the below code in it. This will create the first view function which will be called when hitting base project URL i.e. localhost:8000/ on the local server.
from django.shortcuts import render # Create your views here. def home(request): data = dict() return render(request, 'hw/home.html', data)
Include the hw app's URLs in the main project URLs file.
Open helloworld/urls.py file and add below line in urlpatterns.
from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path(r'', include('hw.urls', namespace="hw")), ]
Now finally add hw in installed apps in helloworld/settings.py file.
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'hw' ]
Now start the Django development server by running the command.
$ python manage.py runserver
This will run the python HTTP server on the localhost and 8000 port. If you want to run it on a different port, use port number in the command. For example
$ python manage.py runserver 8888.
Use the below command to make your project available for everyone on the network.
$ python manage.py runserver 0.0.0.0:8000
Open the web browser and got to URL localhost:8000 and you will be able to see the home page.
