You can do it like so
Order.objects.select_related("customer").prefetch_related("detail_order_set").all()
Note:
If u used related name in your models fieldc change the name in bracets with your related name
Then in your template make a loop for each order in orders and show what you want
Juan Carlos
ok. Thank . Ill try it
Juan Carlos
.. I think a dont understand prefech vs select...
Ammar
You may need to make two loop one for orders and one for detail
Juan Carlos
ok
Ammar
.. I think a dont understand prefech vs select...
As i know select related is used on you have one object (like each order belong to one customer ) whereas prefetch_related is used when you have many objects belong to one ( each order can have many detail_order )
Sorry for the bad english
In django docs they are explained in a good way
Juan Carlos
what is detail_order_set ?? this shoud be a fk in order ?
Ammar
what is detail_order_set ?? this shoud be a fk in order ?
The field that you used
models.forgeinkey()
in orm you can fetch the related object by the name followed by set
Like if you have
Class items:
order = models.forgienkey()
You can get items for an order using
order.items_set
You can also specify a name using related_name in the field
Juan Carlos
Ok 👌🏻
Ammar
Docs will help you alot
Juan Carlos
Thanks for helping

Can you give me some ideas ?
Pick a Frontend guy
Create a social media webapp having most of the features like profile, post, chat, websocket messages, stories.
Create multi vendor e commerce having user and merchant profile, products, orders, multiple payment gateway, merchant chat, vendor panel, maybe additional delivery person webapp with live location for delivery
This will be good to showcase on resume/portfolio for both of you
+
enough complex db structure and reusable content like websockets chat, multi tenant user role management, payment gateways,

Hi all, i am trying to make use of the easy-thumbnails app, But unfortunately i cannot see the image being rendered. What could possibly be the reason for this.
{% load thumbnail %}
<a href=“{{ image.image.url }}”>
<img src=“{% thumbnail image.image 300x0 %}>
</a>
When I render the image normally it works just fine.
I’m using easy-thumbnails==2.8.1

I have a question about drf-spectacular. I have an endpoint with ChoiceField and DRF makes a response like i want. It accepts and returns a full-value of choice
{
...
"status": "In stock",
...
}
But in swagger it renders as short value like:
{
...
"status": "I",
...
}
So my question is: How can i render it properly in swagger instead of writing example by myself ?

Hi everyone, here is a concept question regarding where a process should be put? In views.py or serializer.py.
Here is a get_product_detail_info.py which could provide the dictionary structure info from outside. I’m not sure if this process that to get the info from outside should belong to serialization, or it is divided into views.
Thank you.

guys any orm method to make a queryset ordered before another queryset chatgpt gave first_queryset | second_query but this is not getting me ordered like first_queryset first and second_queryset after that .
Максим
order = ...
for seller_order in order.sellers_orders.all():
    seller_order.state = 'new'
    seller_order.save()
order.save()
return Response(BuyerOrderSerializer(order).data)
Why seller_order.state = 'new' and seller_order.save()
Changes state only in db, not in serializer?
I see old value of state in serializer.data

Hey guys.
Somebody have a video tutorial, about, how deploy a django project using Hostinger?
Is it a hosting service or vps vendor?
Denilson

Vps.
Because the Hostinger hosting service, don’t support Django.
Sanitizer
Guys, how can I host my Django api
Muflone
Vps.
Because the Hostinger hosting service, don’t support Django.
Then use any guide to install your Django project on vps, hostinger is not relevant
Sunil
Hey guys.
Somebody have a video tutorial, about, how deploy a django project using Hostinger?
Hostinger Supports Django over VPS.. they have a predefined OS template you can try it and customize as per your requirement.. Makes sure you change all necessary security settings and passwords for your application safety and security. Below is the link for the same.. all the very best..
You can find articles on hostinger site itself.
https://support.hostinger.com/en/articles/4965922-how-to-change-the-operating-system-for-your-vps
There, you will find the Change Your Operating System section:
Choose the one that suits your needs the most:
OS with Control Panel - easier to use, especially for beginners
Plain OS - option suits advanced users and users who wish to install a custom panel manually
Applications - these are Ubuntu-based templates that include the automatic installation of applications such as Django, Drupal, Joomla, WordPress, and more

I think there is no queryset linked to the view

I found that object "order" not changes.
order = ...
for seller_order in order.sellers_orders.filter().all():
seller_order.state = 'new'
seller_order.save()
Then
for seller_order in order.sellers_orders.all():
seller_order.state # 'old'
it caused by FILTER.
Without FILTER changes applies.
Why????????

may be you have a typo in first filtering check the first filtered queryset is not empty
