Primeiro é necessário a criação do ambiente virtual, por isso vamos usar.
python3 -m venv venv
Após isso é necessários ativar o ambiente virtual para instalarmos as
bibliotecas necessárias.
#LINUX source venv/bin/activate #WINDOWS venv\Scripts
\activate.bat #OU venv\Scripts\Activate.ps1
Com o ambiente ativo só nos falta instalar as bibliotecas.
pip install django pillow
Agora precisamos criar a estrutura base do projeto Django, ou seja
devemos utilizar.
django-admin startproject plataforma_cursos .
Vamos configurar o nosso arquivo settings.py
""" Django settings for plataforma_cursos project. Generated by 'djangoadmin startproject' using Django 3.2.6. For more information on this
see https://docs.djangoproject.com/en/3.2/topics/settings/ For the full
list of settings and their values, see https://docs.djangoproject.com

inside the project like this: BASE_DIR / 'subdir'. BASE_DIR =
Path(__file__).resolve().parent.parent # Quick-start development settings

O próximo passo é criar as URL dentro de usuário.
from django.urls import path from . import views urlpatterns = [
path('cadastro/', views.cadastro, name = 'cadastro'),
path('login/', views.login, name = 'login'), ]
Criando as respectivas funções temos:
from django.http.response import Http404 from django.shortcuts
import render from django.http import HttpResponse def
cadastro(request): return HttpResponse('cadastro') def
login(request): return HttpResponse('login')
Mas agora precisamos renderizar templates HTML.
Vamos então criar um template base.
<!doctype html> <html lang="pt-BR"> <head> <meta
charset="utf-8"> <meta name="viewport" content="width=devicewidth, initial-scale=1, shrink-to-fit=no"> <link

class="btn btn-success btn-lg" type="submit"> <a href="#"
class="btn btn-info btn-lg">Logar</a> </form> </div> <div
class="col-md-3"> </div> </div> </div> {% endblock %}
Agora só precisamos alterar a view
def cadastro(request): return render(request, 'cadastro.html')
Já estamos renderizando uma página HTML para o cadastro, vamos
repetir o processo para a página de login.
{% extends 'base.html'%} {% block 'titulo'%} Logar {% endblock%}
{% block 'body' %} <div class="container"> <div class="row">
<div class="col-md-3"> </div> <div class="col-md"> <br>
<h1>Login</h1> <hr> <form method="POST" action="#">

Vamos então criar um superuser
python3 manage.py createsuperuser
Aprimorando a área administrativa.
