Hello Word in Django 2: How to start with Django 2


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.


Steps:

Create a virtual environment using python3. 

virtualenv -p /use/bin/python3.5 venv


Activate the virtual environment.

source venv/bin/activate


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.
