How to write a Model management command so that if you call it in the templates through the cycle, the request to the database does not go again every time in the cycle, but so that it is only once (even if this manager is called 200 times in the cycle)

count = self.get_descendants(include_self=True).aggregate(o_count=Count('outlines'))

if you want the whole method call to be cached, you can use https://pypi.org/project/methodtools/

Is it possible to implement this without third party packages?

Is it possible to implement this without third party packages?
functools comes with lru_cache but apparently it doesn't work with methods. that's why you need methodtools (https://docs.python.org/3/library/functools.html)
Д
if you can get your thing to work using that?
Д
but if you don't want to cache the WHOLE function but avoid the time-costing parts, then you can do something like pre-selecting or pre-fetching things - I'm not sure how well Django caches those between calls though, so you might have to save state, depending on where the Query\Objects live

Surely you did not understand the essence of the question.
The question was that the code works absolutely well here. But when I call this method in the template, every time the command is called in the loop, the same answer is returned for each foreach element. I tried using super to make an implementation, if there are some possibilities other than third-party packages, it would be great

and you gave a shitty description of the problem. I'm giving you alternatives

functools is part of the python standard AFAIK

OK. I will take a look at this implementation
Д
OK. I will take a look at this implementation
I'm assuming you want to avoid calling this a billion times because calling it once is really slow?
Д
not because you don't know how to program
Избранное
and now I want to know the finished implementation, rather than how to debug the code
Д
maybe i'm lazy :)
so you don't know how to program and you want me to solve a problem for you that should be already solved?
Д
functools won't solve wrong code. it will make life harder.

I wanted to know the solutions in order to better relate to this problem.

okay so are you saying that you want the function to return a DIFFERENT answer on each call?
Д
or that it won't be called more than 1 time or what

OMG)))) you solved this problem)
Д
when people ask questions, I often solve them when they interest me, without telling the answer ;) no, but 99% of the time I talk people through, and I ask lots of questions
Д
when you do this for fun, you learn what mistakes happen. then you become a machine at solving problems.
Д
I've been doing this for probably 10 years
Д
I even sometimes do people's homework but don't give them the solutions.

Most likely you haven't add the app in settings or you have the app in a subfolder

A third option could be you are not executing the correct environment

i have problem with assertRaise
In my code i has
except ValueError:
raise ValidationError(
"qwerty"
)
And when i'm writing tests:
self.assertRaises(ValidationError, self.serializer.to_internal_value(self.data3))
where data3 is invalid value
Why do i have
E rest_framework.exceptions.ValidationError: [ErrorDetail(string='qwerty.', code='invalid')]

I think you had to split the function and its parameters separately in the self.assertRaises

people often use JSON Web Tokens (JWT) for authentication and authorization. that means there's a separate server that gives permissions to access the Django systems, but there are lots of things here that require very careful attention.
Д
I don't have any clean answers for this.
Д
I'm still trying to grasp how to do it properly.
Saadi
Yeah! this is going very complicated. I have searched a lot. But mostly I have got very basic solutions .

Django has basic auth built-in; and you can install some extras to get the JWT stuff going too

if you can write the frontend for it, I think yes

you'll have to write the AJAX calls and the whole thing will be written from scratch. there are no templates (or well, the idea is to not have)

You could use the django-allauth plugin which includes all of this.
• Login (account_login)
• Signup (account_signup)
• Logout (account_logout)
• Password Management
• Password Reset (account_reset_password)
• E-mails Management (account_email)
• E-mail Verification
• Social Connections
... and more...

Thanks brother @Andrej1a
You're welcome.
There are so many good plugins for Django. This is one of the reasons I like it so much.
