For my project i wrote account, cart, orders and shop apps.
order/models:
from django.db import models
from shop.models import Product
class Order(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
email = models.EmailField()
address = models.CharField(max_length=250)
postal_code = models.CharField(max_length=20)
city = models.CharField(max_length=100)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
paid = models.BooleanField(default=False)
class Meta:
ordering = ('-created',)
def __str__(self):
return 'Order {}'.format(self.id)
def get_total_cost(self):
return sum(item.get_cost() for item in self.items.all())
class OrderItem(models.Model):
order = models.ForeignKey(Order, related_name='items',
on_delete=models.CASCADE)
product = models.ForeignKey(Product, related_name='order_items',
on_delete=models.CASCADE)
price = models.DecimalField(max_digits=10, decimal_places=2)
quantity = models.PositiveIntegerField(default=1)
def __str__(self):
return '{}'.format(self.id)
def get_cost(self):
return self.price * self.quantity
account/models is empty
account/views:
from django.contrib.auth import login as auth_login
from django.shortcuts import render, redirect
from .forms import SignUpForm
from orders.models import OrderItem, Order
from django.contrib.auth.decorators import login_required
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
user = form.save()
auth_login(request, user)
return redirect('/')
else:
form = SignUpForm()
return render(request, 'accounts/signup.html', {'form': form})
@login_required
def account(request):
my_orders = Order.objects.all()
order_items = OrderItem.objects.all()
return render(request, "accounts/my_acc.html",
{"my_orders": my_orders, "order_items": order_items})
As you can see in account function i get all orders , but i don't know how to filter orders for user. What do i want is - when user enter in his account he can see all his previous orders.
How can i do that?
You first need to associate your Order with a User:
from django.contrib.auth import get_user_model
User = get_user_model()
class Order(models.Model):
user = models.ForeignKey(User, on_delete=models.PROTECT, related_name='orders')
# insert other fields here
See referencing the user model for what is going on here.
Now you have a relationship between Order and User, which means you can filter for a given user's orders like this:
def account(request):
my_orders = Order.objects.filter(user=request.user)
You will of course need to associate an Order with a User when the order is created in the first place - whatever code that creates the order will need to do that.
