Re: Issue in filtering .....(want to show only the products that are sold and have status of paid in orders App)

there is no m2m relation in products and cart model....

carts/models.py

class CartItem(models.Model):
    cart = models.ForeignKey("Cart")
    item = models.ForeignKey(Variation)
    quantity = models.PositiveIntegerField(default=1)
    line_item_total = models.DecimalField(max_digits=10, decimal_places=2)

    def remove(self):
        return self.item.remove_from_cart()

    def __unicode__(self):
        return self.item.title

class Cart(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True)
    items = models.ManyToManyField(Variation, through=CartItem)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True)
    subtotal = models.DecimalField(max_digits=50, decimal_places=2, default=0.00)
    .....

    def __unicode__(self):
        return str(self.id)

products/models.py

class Product(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    seller = models.ForeignKey(SellerAccount)
    # shop = models.ForeignKey(Shop)
    title = models.CharField(max_length=120)
    description = models.TextField(blank=True, null=True)
    price = models.DecimalField(decimal_places=2, max_digits=20)




class Variation(models.Model):
    product = models.ForeignKey(Product)
    title = models.CharField(max_length=120)
    price = models.DecimalField(decimal_places=2, max_digits=20)
    sale_price = models.DecimalField(decimal_places=2, max_digits=20, null=True, blank=True)
    active = models.BooleanField(default=True)
    inventory = models.IntegerField(null=True, blank=True) #refer none == unlimited amount

    def __unicode__(self):
        return self.title

I'd need to see the full Cart model to confirm, but try something like this to get all products for Orders with the paid status:

def get_products(self):
 orders = Order.objects.filter(user=self.user, status='paid')
 products_list = list()
 for o in orders:
  for p in o.cart.products:
   products_list.append(p)

 return products_list

This depends on their being a ManyToMany relationship to Product in the Cart model.

this user is a F.K in products model, orders model , carts model right.
cart is also a F.K in orders like this

class Order(models.Model):
    status = models.CharField(max_length=120, choices=ORDER_STATUS_CHOICES, default='created')
    cart = models.ForeignKey(Cart)
    user = models.ForeignKey(UserCheckout, null=True)
    billing_address = models.ForeignKey(UserAddress, related_name='billing_address', null=True)
    shipping_address = models.ForeignKey(UserAddress, related_name='shipping_address', null=True
......
    seller = models.ForeignKey(SellerAccount, null=True)......i have added this field now to relate sellers app with orders...

now advise me 
how to filter orders of products with status of paid .( of a logged in user )

:)

Can you share the Cart model? The Order has a foreign key to Cart. I think that may be the model holding details of the products.

How are you associating a product with an order? Is there a way to get a list of products sold for each order?

Thanks for you kind response ...I am stuck in it :(

I have seller as a foreign key in Product model..

products/models.py

class Product(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    seller = models.ForeignKey(SellerAccount)
   
    title = models.CharField(max_length=120)
    description = models.TextField(blank=True, null=True)
    price = models.DecimalField(decimal_places=2, max_digits=20)

Hi,
 While you didn't show us the Product model, I assume it has a ForeignKey to the Order model. To filter for Products that have an Order with a sold status, you should look at the documentation for filtering on relationships at https://docs.djangoproject.com/en/1.10/topics/db/queries/#lookups-that-span-relationships.

Jibran

        products = self.get_products()
        ******************************************************
          THIS IS THE PROBLEM AREA ????? i want to show orders of the products i got from (products = self.get_products()).
        keeping this thing in mind that order is completed if its status set to be 'paid'....
        OR
        In other words i want to show products of the user that is logged in if the status of that products are paid.
        *****************************************************
        sold = Order.objects.all().filter('products')
        return sold


sellers/views.py

class SellerDashboard(SellerAccountMixin, FormMixin, View):
    form_class = NewSellerForm
    success_url = "/seller/"
            context["products"] = self.get_products()
           
            context["sold_products"] = self.get_sold_products()

sellers/dashboard.html

{{ sold_products }}

i hope someone will definitely figure out my problem....
regards....
