select_related will work if i want to reduce queries from B and C models, to get some info from A model like:
c = C.objects.filter(a_id=1).select_related('a')
print(c.a__some_info)

How can I make a queryset to return a model entity and a count of how many times it appears as fk in another model table?

Can you show me a sample site made with django?

You try to count? Please explain again:)

Yep, it worked, it was actually pretty simple, I just didn't know about the "annotate" method
Cacio Lucas
Thanks anyways :)
Cacio Lucas
I'm trying now to annotate a field that should be (timedelta(days=F('integerfield))+F('datetimefield)), but It's not working, does anyone know how can I do it?

Frankly i am not able to find much difference between modelviewset and generic views.

GenericViews don't cover all scenarios, I mean with the ViewSet based on your model you have already a full CRUD

How to add external css file in django...?
Make it a static file. And connect it in the main settings.py file that you created.
It's found in the last section known as STATIC.
I'd there are images you could also store it there.
DM me and let's talk if you still can't do it

For the 1st one I don't remember honestly
For the second one just use environment variables

For the second question I can recommend you to use different environment. Create file(don't forget to add it in your .gitignore) with private data of your project, then open settings.py and rewrite security variables by calling it from your personal file.
Here is library which may help you https://django-environ.readthedocs.io/en/latest/

he asked for datatables actually, which is pretty straightforward to use, just importing a JS file 🤷🏻♂️ but yes, you're right, he doesn't have enough searching skills

Hey, I am working on payment module. Integrating with payment gateways.. What design pattern should I follow for good code and best performance.. As of now am integrating only one gateway, but in future we will add multiple gateways, coupon system, running offers and incentives on orders, etc. I would like to start with all those in mind, however am not sure which pattern or method to use for good code and good performance. Any suggestions?

For design it'll depend on design of you database whether you have a separate gateways for coupons and orders ...

Guys, how to get to know if self-referecing onetoone field is already referenced by another object? (I need to handle this case: "duplicate key value violates unique constraint")
Oleg
I know that it's easy to get rid of needless objects (that are already have reference from somewhere else) in filter (with pk__isnull)
Database.objects.filter(db_dr_field__pk__isnull=True)
but how to apply it to one object and check only one object reference?
I want something like: obj.related_name__pk__isnull
