Setup - Manually Within Visual Studio

follow the following to create a new python project and to create a virtual environment:

Create a python project in Visual Studio

Creating a virtual environment in Visual Studio

The last link above also shows how to create a 'setup.py' to install Django using pip, use this method to install Django.

In College

You will need to complete the above links, but the installation will not work. You will need to install django by replacing the contents of your environment folder with This. College are currently blocking the ports required to install modules into your python environment.

Easy Method: just use this project for yours.

Management

Now use this program: Django management program to create a management app to run the key commands needed for django.

New Project

  • Run the management program and choose '1' as your first option to run django_admin
  • Now selected option 1 to 'StartProject'
  • Now enter a project name, eg 'MyProject'

New App

  • Run the management program and choose '1' as your first option to run django_admin
  • Now selected option 1 to 'StartApp'
  • Now enter a app name, eg 'MyApp'

Run Server

  • Run the management program and choose '2' as your first option to run manage
  • Now selected option 1 to 'RunServer'

Make Migrations

  • Run the management program and choose '2' as your first option to run manage
  • Now selected option 2 to 'MakeMigrations'

Migrate

  • Run the management program and choose '2' as your first option to run manage
  • Now selected option 3 to 'Migrate'

Create Super User

  • Run the management program and choose '2' as your first option to run manage
  • Now selected option 4 to 'CreateSuperUser'

You Will Need to

You will need to run option 1 & StartProject followed by StartApp, Then option 2 & Migrate followed by RunServer.

Finally so that you can see all of the files within the project, make sure 'All Files' is selected in solution explorer:

Show all files.png

You can also set your django management program as the startup file, by right clicking it in solution explorer and then click 'Set as Startup File'.

Setup - Manually on Own Machine

This will create a web app based on Django 2.2, this is the latest version of Django and isn't entirely compatible with the Django 1.11 used by Visual Studio.

Setup the Path

You will need to ensure your system path is set to access the python folder and the scripts folder. Search for 'path' in the search bar, and click 'edit the system variables':

Now click 'Environment Variables':

Now select Path and click edit:

Now look on your system to find where Python is installed, make a note of the folder and also check to see if it also has a script folder. Now add these values to the Path:

Install Django

Now to install Django you can enter the following command:

python -m pip install django

If you have set the path above it should work, you might need to restart your computer after you change the path. This command should install Django and all of its dependencies.

Create an app

With Django installed above, it should add django-admin into your scripts folder. We will use this to create a new Django app. But first we need to create a folder for your app, and then run the command prompt and go to the folder location:

Capture 5.gif

Now we can run this command to create a blank Django app:

django-admin startproject myapp

This will create a folder called myapp, and it will contain everything required for a Django app. If you go into the myapp directory you will see manage.py:

Capture 6.gif

Now we need to run a few commands, firstly:

manage.py migrate

Then we need to create a superuser, so now type this command:

manage.py createsuperuser

You will need to follow the instructions to create a username and password.

Now to run the app you will need to run the command:

manage.py runserver

This will start the server and tell you the address to access the app:

Capture 7.gif

Now open a browser and enter the ip address above, ie http://127.0.0.1:8000 :

Capture 8.gif

Change the url to 'http://127.0.0.1:8000/admin' to access the admin features:

You should be able to login with your superuser details:
