Python 3.6.4 : Test Django version 2.1.1 on Windows O.S.

I used the python version 3.6.4 to test the last Django framework version.
Add your python to the path environment variable under Windows O.S.
Create your working folder:

C:\Python364>mkdir mywebsite

Go to the folder to install all you need:

C:\Python364>cd mywebsite

Use a virtual environment using the virtualenv command:

C:\Python364\mywebsite>python -m venv myvenv
C:\Python364\mywebsite>myvenv\Scripts\activate
(myvenv) C:\Python364\mywebsite>python -m pip install --upgrade pip
(myvenv) C:\Python364\mywebsite>pip3.6 install django
Collecting django
...

If you try to run again this command you will see the version of Django:

(myvenv) C:\Python364\mywebsite>pip3.6 install django
Requirement already satisfied: django in c:\python364\mywebsite\myvenv\lib\
site-packages (2.1.1)
Requirement already satisfied: pytz in c:\python364\mywebsite\myvenv\lib\
site-packages (from django) (2018.5)

You need to run the django-admin command:

(myvenv) C:\Python364\mywebsite>cd myvenv
(myvenv) C:\Python364\mywebsite\myvenv>cd Scripts
(myvenv) C:\Python364\mywebsite\myvenv\Scripts>django-admin.exe startproject mysite
(myvenv) C:\Python364\mywebsite\myvenv\Scripts>dir my*
(myvenv) C:\Python364\mywebsite\myvenv\Scripts>cd mysite
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite&

Make a change to settings file:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>cd mysite
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\mysite>notepad settings.py

Change UTC timezone:

TIME_ZONE = 'Europe/Paris'

Change host:

ALLOWED_HOSTS = ['192.168.0.185','mysite.com']

The next step is to use these commands:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\mysite>cd ..
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py migrate

  Applying auth.0009_alter_user_last_name_max_length... OK
  Applying sessions.0001_initial... OK

Let's try these steps with the browser:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py runserver
 192.168.0.185:8080

This is the result:

Let's start Django application named myblog and add to settings.py :

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py startapp
myblog

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>dir
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>cd mysite
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\mysite>notepad settings.py

Search into settings.py this line and add 'myblog' and comma after, see:

# Application definition

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

Let's change models.py from myblog folder:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\mysite>cd ..
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>cd myblog
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\myblog>notepad models.py

Add this source code:

from django.db import models
# Create your models here.
from django.utils import timezone
from django.contrib.auth.models import User

class Post(models.Model):
 author = models.ForeignKey(User,on_delete=models.PROTECT)
 title = models.CharField(max_length=200)
 text = models.TextField()
 create_date = models.DateTimeField(default=timezone.now)
 published_date = models.DateTimeField(blank=True, null=True)
 
 def publish(self):
  self.publish_date = timezone.now()
  self.save()
 def __str__(self):
  return self.title

Go and run this command manage.py for model Post with makemigrations myblog and migrate myblog :

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\myblog>cd ..
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py 
makemigrations myblog
Migrations for 'myblog':
  myblog\migrations\0001_initial.py
    - Create model Post
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py migrate 
myblog
Operations to perform:
  Apply all migrations: myblog
Running migrations:
  Applying myblog.0001_initial... OK

Add this source code to admin.py from myblog folder:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>cd myblog
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\myblog>notepad admin.py

Let's test again:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite\myblog>cd ..
(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py runserver

Check the admin interface with add admin word to link, see: http://192.168.0.185:8080/admin

If you see some errors this will be fixed later.
Let's make a superuser with this command:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py 
createsuperuser
Username (leave blank to use 'catafest'): catafest
Email address: catafest@yahoo.com
Password:
Password (again):
This password is too short. It must contain at least 8 characters.
Bypass password validation and create user anyway? [y/N]: y
Superuser created successfully.

Run again this command and log in with your user and password:

(myvenv) C:\Python364\mywebsite\myvenv\Scripts\mysite>python manage.py runserver
 192.168.0.185:8080

This is the result of users and posts.

The result is this:

I don't make settings for URL and view.

PyOpenGL: Fix Attempt to call an undefined function glutInit .

This tutorial is about how to fix this error using Python version 3.6.4 :

OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit,
check for bool(glutInit) before calling

First I start with a common pip3.6 install.

Scripts>pip3.6.exe install PyOpenGL

When I run my python script code I got this error:

I use the whl files from here.

This allow me to run well the python script with PyOpenGL python module.
