Aula 49 – Loja Online – Django – Processo de Checkout

O processo de checkout envolve algumas coisas.

Processo de Checkout

1 – Carrinho ==> Checkout View

  • Login/Register
  • Shipping Address
  • Billing Info
    • Billing Address
    • Credit Card / Payment

2 – Billing App / Component

  • Billing Profile
    • User or Email (Guest Email)
    • Generate Payment Processor Token (Stripe or Braintree)

3 – Orders / Invoices Components

  • Connecting the Billing Profile
  • Shipping / Billing Address
  • Cart
  • Status — Shipped? Cancelled?

Orders

Vamos começar criando o componente Orders, isto é, o app Orders.

Com o ambiente ativado entre na mesma pasta onde tá o manage.py e execute:


python manage.py startapp orders

O carrinho(Cart) prepara o pedido(Order), o Order é o que vai ser manipulado pelo backend.

Vamos registrar o componente orders na lista INSTALED_APPS no e_commerce/e_commerce/settings.py

e_commerce/e_commerce/settings.py

Abra o e_commerce/orders/models.py e coloque o conteúdo abaixo.

e_commerce/orders/models.py


from django.db import models
from carts.models import Cart

ORDER_STATUS_CHOICES = (
    ('created', 'Criado'),
    ('paid', 'Pago'),
    ('shipped', 'Enviado'),
    ('refunded', 'Devolvido'),
)

class Order(models.Model):
    order_id = models.CharField(max_length = 120, blank = True)
    # billing_profile = ?
    # shipping_address = ?
    # billing_address
    cart = models.foreignKey(Cart, on_delete=models.CASCADE, null = True)
    status = models.CharField(max_length = 120, default = 'created', choices = ORDER_STATUS_CHOICES )
    shipping_total = models.DecimalField(default = 5.99, max_digits = 100, decimal_places = 2)
    # Order total = models.DecimalField(default = 0.00, max_digits = 100, decimal_places = 2)

    def __str__(self):
        return self.order_id

Agora rode o makemigrations


python manage.py makemigrations

E depois o migrate


python manage.py migrate

Abra o e_commerce/orders/admin.py e modifique para que fique assim:

e_commerce/orders/admin.py


from django.contrib import admin

from .models import Order

admin.site.register(Order)

Agora acesse http://127.0.0.1:8000/admin

Veja que agora o Orders aparece no painel admin.

Por essa aula é só, na próxima a gente vai ver como gerar um id aleatório para as Orders.
