I need help with hosting, I want to host my Django project. please dm if you have a solution. 6$ is what heroku charge. Let me know if you can get it done somewhere else with ssl.
Tin
??
SJ
So you mean heroku started charging hosting
I mean to use ssl you need to buy premium package which coat you around 6$ per month

Celery having some issues with my task 🥺🥺 anything advanced than that?
IM~Exynos
You can develop your own library...
😬😬 not much time to do that's why asking it.

😶 tbh celery is pretty much simple, try a few YouTube tutorials... You should be good to go

Hi. Why doesn't it work like that? {% for lang_code, lang_name in languages %} {% language lang_code %} <li><a href="{{ request.path }}">{{ lang_name }}</a></li> {% endlanguage %} {% endfor %} </ul> And, for example, it switching languages: {% for lang_code, lang_name in languages %} {% language lang_code %} <li><a href="{% url 'index' %}">{{ lang_name }}</a></li> {% endlanguage %} {% endfor %} </ul>

If you have Django > 3 Use TextChoices to create an enum And then you can use the display name to get Active In any case, the get display of the field will give you the verbose name

Hi. A weird question: is there any way to make a queryset that is filtered with a condition like... like takewhile/dropwhile? (Assuming it is somehow ordered, of course). For example, which contains of the elements of the query, until some condition starts to happen.
() { :;}; echo Nickolas
How about overriding get_queryset() and checking for your conditionals
Alexander
What is filterfalse/dropwhile. Two terms i never heard of
Things from itertools: https://docs.python.org/3/library/itertools.html#itertools.dropwhile
Alexander
How about overriding get_queryset() and checking for your conditionals
This would happen on the Python level, what is scary for large queries.
Alexander
I wonder if that can be specified somehow to stay on SQL layer of the queryset
() { :;}; echo Nickolas
Unless the orm you're using supports it idk if you can drag this to the SQL layer
Alexander
That was the whole hope that Django's ORM does support it 🙁
() { :;}; echo Nickolas
Perhaps you can do whatever you need to do in a celery task and keep the results stored somewhere and fetch when you need it? Unless you need it real time
() { :;}; echo Nickolas
That way you wouldn't block the django layer and keep it in a separate task
Alexander
My real case is that I am basically doing a weird pagination. (So this obviously must happen inside my django view/code). And the syntax of this pagination is something like records(afterUid, number). Or records(beforeUid, number)
() { :;}; echo Nickolas

Sounds to me - correct me if I'm wrong - that you're attempting to "reinvent the wheel" in a sense that Django offers pagination built-in. Do you have a specific reason to not use the built-in pagination?
Alexander
It is very trivial if you evaluate the queryset, and use those itertools goodies directly; but... but my inner DBA begs me to keep that in SQL
Alexander
Also I don't remember if the builtin pagination offers the “afterUid/number” pattern, rather than basic “limit/offset”.
() { :;}; echo Nickolas
So you're using graphene-django then? Sorry, my graphql knowledge is limited to tutorials
Alexander
There are some reasons why limit/offset is unacceptable in my case; limit number is not stable, so if the data is regularly updated, it will move.
Alexander
So you're using graphene-django then? Sorry, my graphql knowledge is limited to tutorials
Sure; but most good pagination is still to be done manually, even then 🙁 especially in my “afterUid” stable indexing case
Alexander
So you're using graphene-django then? Sorry, my graphql knowledge is limited to tutorials
Btw, after years of DRF, switching to Graphene was like... a grasp of fresh air. Everything became easier and shorter.
() { :;}; echo Nickolas
Afraid i can't contribute more than I already have. Everything i know is built on my experience with DRF that has baked in pagination which never let me down
() { :;}; echo Nickolas
Good luck tho, do provide an update if you've figured it out.
Alexander

Yeah, basically I am trying to do something similar to CursorPagination of DRF, except with two cursors (in both directions), and do it manually, and stay on SQL level as much as I can 🙂 Doing this with dropwhile/filterfalse is rather easy, though; virtually two lines. Maybe I'll live with evaluating too much...
Alexander
Thanks for brainstorming!
() { :;}; echo Nickolas
Thanks for brainstorming!
With pleasure

Hey guys i just deployed my api with heroku, but what i find is that my api's is failing when handling nested fields, but it works fine when i run them locally
M
https://postimg.cc/gallery/wtFZKpS , like this when i visit the order/pk/items it should give me 2 fields so that i can input the data, but its only giving me order_pk on the heroku app
Mirco
Thank you. Whare i write displey name? Is it function?
You can find it on Django doc when you have choices , you can access to get_FOO_display() method to get the display name where foo is your field name It's a method of your model In Django setializer you can use the source attribute to inject it

You might check the docs from nginx or apache. This is not really Django related

Yes, just backup the data first python manage.py dumpdata > datadump.json Change the database settings in your project and load it python manage.py loaddata datadump.json
Xeon
Challenge yourself 😉
Alright I will thanks
Xeon
Wow thanks
Xeon
Could using sqlite3 be the reason why am trying to upload my app to heroku and it's saying app error?
Xeon
Yep, heroku doesn't support sqlite
Ok then will do as you are saying and try it out
