Dica 06 - Criando o projeto Django

Importante: remova a \ no meio das tags.

python -m venv .venv
source .venv/bin/activate

# .venv\Scripts\activate  # Windows

pip install django python-decouple django-extensions
pip freeze | grep -E 'Django|python-decouple|django-extensions' >> requirements.txt

Senão digite apenas pip freeze e copie os pacotes manualmente.

Criando a estrutura de templates

Vamos trabalhar com herança de templates.

mkdir -p backend/core/templates/includes
touch backend/core/templates/base.html
touch backend/core/templates/index.html
touch backend/core/templates/includes/menu.html
touch backend/core/templates/includes/footer.html
touch backend/core/templates/includes/pagination.html

# ou

# touch backend/core/templates/includes/{menu,footer,pagination}.html

Edite base.html

<!-- base.html -->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">
