Django

Introduction

1. Install Python if it is not there.
2. Decide what you need virtual environment or not
3. Install Django

Installing Django on your host is quite simple - you can study the instructions below.

To install Django on virtual hosting It will take more manipulation. How to do it on the hosting Beget you can find out from my article

«Install Django on virtual hosting»

Many modern hosting The procedure will be similar.

Installation Django

The first thing I recommend is to update the pip.

python3 -m pip install --upgrade pip

Then install Django directly.

python3 -m pip install django

Check the installation

python3 -m django --version

3.2.4

or

python3 -m pip list

Package Version ----------------- -------- asgiref 3.3.4 Django 3.2.4 pip 21.1.2 pytz 2021.1 setuptools 39.0.1 sqlparse 0.4.1 typing-extensions 3.10.0.0

Django Teams

The list of Django commands can be obtained by performing

python3 -m django help

Type 'python -m django help <subcommand>' for help on a specific subcommand. Available subcommands: [django] check compilemessages createcachetable dbshell diffsettings dumpdata flush inspectdb loaddata makemessages makemigrations migrate runserver sendtestemail shell showmigrations sqlflush sqlmigrate sqlsequencereset squashmigrations startapp startproject test testserver Note that only Django core commands are listed as settings are not properly configured (error: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.).

Each project usually uses one or more applications (application).

When all applications and configurations are combined, they make up a web application.

applications + configurations = web application

Create the first app.

python3 manage.py startapp first_app

A first app directory will appear with the following files:

admin.py

apps.py

__init__.py

migrations

models.py

tests.py

views.py

Go to Project Name/Project Name

Edit Project Name/Project Name/settings.py

You need to add to the list of installed applications our new app first app

INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'first_app', ]

Restarting the server

python3 manage.py runserver

If the restart is carried out using a script, we perform (As far as I know, this is true for beget and dreamhost hosting)

(docker) andreyolegovich@server:~/eth1.ru [0] $ touch tmp/restart.txt

Create a view and link to the URL

The process consists of at least three actions.

1. In a directory with an application, for example Project_Name/first_app file views.py You need to create a function that will listen to the URL.
2. The main directory of the project, for example Project_Name/Project_Name file urls.py You need to import this function.
3. Still in urls.py You need to add a combination of url and functions in urlpatterns

Example: Go to the directory with Project Name/first app and edit views.py To create our first view.

Each view must return some HttpResponse object.

Add the following code to the file Project_Name/first_app/views.py:

from django.http import HttpResponse def about(request):    return HttpResponse("About Us!")

Now you need to link this view to some URL

Add the following code to the file urls.py

from first_app.views import about urlpatterns = [ path('', 'about') ]

In urlpatterns, you can specify the url in different ways

urlpatterns = [ path('', welcome), # Main page page path('welcome.html', welcome), #url with .html extension path('admin/', admin.site.urls), #url with a slash at the end path('date', date) #url without extension ]

Pay attention to welcome – one feature can serve multiple URLs

Add the domain on which you deploy the site in the ALLOWED HOSTS file (from the project) settings.py

ALLOWED_HOSTS = ['http://www.eth1.ru','127.0.0.1','localhost','eth1.ru','www.eth1.ru']
