Example 2: django basic steps

# --------- Basic steps for working with Django on a MAC ---------- #

 1º - Create a virtual environment by giving this command:
  
 >> python3 -m venv "name_of_env"  
  
  
 2º - Activate this virtual environment:

 >> source "name_of_env"/bin/activate  


 3º - Now you can install Django:
  
 >> pip3 install django  
  
  
 4º - To initiate a project in Django:

 >> django-admin startproject "projectName"
 >> cd projectName
 

 5º - To run the server, you need to go to the directory containing 
      manage.py and from there enter the command:
  
 >> python3 manage.py runserver

 
 6º - To create a basic app in your Django project you need to go 
      to the directory containing manage.py and from there enter 
      the command:

 >> python3 manage.py startapp "projectAppName"


 7º - You need to include the app in our main project so that 
      urls redirected to that app can be rendered. Move to 
      "projectName" -> "projectName" -> urls.py and change the
      following:
    
    
from django.contrib import admin 
from django.urls import path, include 
  
urlpatterns = [ 
    path('admin/', admin.site.urls), 
    # Enter the app name in following syntax for this to work 
    path('', include("projectApp.urls")), 
]

Example 3: create django project

$ python manage.py startapp polls
