how to send input date value (GET) to backend - django
I'm trying to send two dates from template to backend through ajax response , in order to check if the two date exists or not! if not exists then return the entire data, but if exists just return the data between that two range def dateTimePrice(request): start = request.GET.get('from') end = request.GET.get('to') print(start,end)# if start and end: datetimes = ImeiInvoice.objects.filter(invoice__created_at__range=(start,end)).annotate( total_price=Sum( (F('price')) - F('discount'),output_field=DecimalField(max_digits=20,decimal_places=3)) ).annotate( total_quantity=( Count('pk') ) ).aggregate( all_price=Sum(F('total_price')), all_qnt=Sum(F('total_quantity')) ) else: datetimes = ImeiInvoice.objects.all().annotate( total_price=Sum( (F('price')) - F('discount'),output_field=DecimalField(max_digits=20,decimal_places=3)) ).annotate( total_quantity=( Count('pk') ) ).aggregate( all_price=Sum(F('total_price')), all_qnt=Sum(F('total_quantity')) ) return JsonResponse(datetimes,safe=False) @login_required def dateTimePriceTemp(request): return render(request,'myapp/datetimes.html') and here is my GET form, to get the two date from $(document).ready(function(){ const spinner = document.getElementById('spinnerDateTimePrice') const start_date = new Date($('#from').val()); const end_date = new Date($('#to').val()); console.log(start_date) console.log(end_date) if(start_date && end_date){ data={ 'from':start_date, 'to':end_date } } function dateTimePrices(){ $.ajax({ type:'GET', url:'/prices/dateTime/data', data:data, success:function(data){ const datetimes = data; var k = '<tbody>'; if(datetimes){ k+= '<tr>'; k+= '<td>' + datetimes["all_qnt"] + '</td>'; k+= '<td>' + datetimes['all_price'] + '</td>'; k+= '</tr>' }else{ k+= '<td class="p-2 text-xs border border-purple-900 md:text-base textpurple" colspan=6>found nothing</td>' } k+='</tbody>' document.getElementById('datetime_list').innerHTML = k } }) } dateTimePrices(); }) <form action="" method="GET"> <div class="col-11 p-1 mt-1 mx-auto text-center row rtl "> <p class="col-12 col-sm-6 … -
Django Data import from JSON file to DB not working with OneToOneFields
I'm currently working on an importer which lets me import a json file from a folder which i get from another server. So far i can import all the regular fields of my model but the parts that are using OneToOneFields are not being imported.

Django handle transaction on filter query
I have a Model that has a "score" attribute and a route that returns the object with the biggest score from the database (MySQL). I want to use multiple instances of the same application (two microservices) and I am afraid that I will face race conditions, both machines returning the same client. How could I make sure that this is not happening? After returning a client, it will be marked as PROCESSED. def getClient(request): client = Client.objects.order_by('-score').filter(state="UNPROCESSED").first() client.state = "PROCESSED" client.save() return HttpResponse(f"<h1>{client.name}</h1>") -

Cannot delete an item from the Django admin interface

How to make some Django Inlines Read Only
I'm using django admin and adding a TabularInline to my ModelAdmin class. Think Author and the inline is Books. How do I make some of those inlines appear read only and some appear editable based on certain characteristics of the model instance for each specific inline? Say I wanted all the books written before 2001 to be read only. And all the books written after that to be editable. I've tried overriding has_change_permission() and using the obj param, but it is receiving the parent and not the instance of this specific inline. -

How can I set the accepted content type in django view
I have some views made in Django. I have realised that the endpoints do not fail with an unsupported media type if I call them with, for instance, binary data instead of json (they only accept json). So, my doubt is: how can I specify the allowed content type of an endpoint in django to make it return a 415 error code? Do I need to implement that logic by hand with a middleware? -
Celery beat sends scheduled task only once and then doesn't send task when restarted
I am using Celery beat to perform a task that is supposed to be executed at on specific time. I was trying to excute it now by changing the time just to see if it works correctly. What I have noticed is it sends the task correctly when I run a fresh command that is celery -A jgs beat -l INFO but then suppose I change the time in the schedule section from two minutes or three minutes from now and then again run the above command, beat does not send the task. Then I noticed something strange. If I go to the admin area and delete all the other old tasks that were created in the crontab table, and then run the command again it sends the task again to the worker. The tasks are being traced by the worker correctly and also the celery worker is working correctly. Below are the codes that I wrote to perform the task. celery.py from __future__ import absolute_import, unicode_literals import os from celery import Celery from django.conf import settings from celery.schedules import crontab from django.utils import timezone from datetime import timezone # Set the default Django settings module for the 'celery' program. … -

DRF serializer validation - discard failed items, keep successful ones?
I have an endpoint (POST, APIView) which expects larger chunks of data that needs to be validated using serializers. However, for many reasons there are times where I'd like to discard a few of them that fail validation. The rest, I still want to add. E.g I'd like to run : serializer = ListingSerializer(data=request.data, many=True) if serializer.is_valid(): serializer.save() Lets say we have a table of listings which has a foreign key to a company table. Therefore I have a nested company serializer as a field. A company only has a name. In order to save some performance I fetch all companies in the init method so is_valid() only makes one query (similar to a select_related). The problem here is that if a single company did not exist, the entire is_valid() will fail and thus I cant run serializer.save(). Is there any elegant way to solve this by discarding the individual items that fail is_valid() so that I can run serializer.save()? class CompanyStringSerializer(serializers.ModelSerializer): class Meta: model = Company fields = ("name",) class ListingSerializer(): company = CompanyStringSerializer() def __init__(self, *args, **kwargs): """ This is executed when the serializer initializes (meaning the query will only run once) """ self.companies = Company.objects.filter(enabled=True) super().__init__(*args, **kwargs) … -
Get current Logged in User in django Rest Framework
I am trying to get current logged in user and upload/send information to frontend. I am new to Rest Framework so forgive my basic level question. I have tried fetching user with request.user and request.auth in my views but I am not able to simply get user. This is my views.py from rest_framework.authtoken.models import Token def get_User (request): # current_user = request.user # context = {"user": current_user} # print(request.user.username) user_id = Token.objects.get(key=request.auth.key).user_id print(request.auth) # Response(context) I am using a custom user model to store data. Every time I am running request.auth or request.user i can see in my django terminal that it keeps going to /verify-auth-token/ URL. How do I get user printed also sent to frontend in React to display in app as well. Any help is appreciated. -
Disable has_changed check in django form
When an entry is saved in results list in django admin site I need it to end up in save_model regardless of whether it has changes or not.

It works, but I suspect it's ugly:) def get_changelist_form(self, request, **kwargs): res=super().get_changelist_form(request, **kwargs) # Ugly? res.has_changed=lambda *args, **kwargs: True return res -
Celery beat not resuming scheduled tasks django
I have used celery & django celery beat to run a predefined scheduled task. When I first run celery worker & then celery beat worker, everything is fine, the task is added to database, and also sent to queue by celery beat worker continuously. But when I stop beat worker and start it again, it no longer works, even though the task is defined in database. What should I do? This is my code for django: # Set the default Django settings module for the 'celery' program. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings') app = Celery('proj') # Using a string here means the worker doesn't have to serialize # the configuration object to child processes. # - namespace='CELERY' means all celery-related configuration keys # should have a `CELERY_` prefix. app.config_from_object('django.conf:settings', namespace='CELERY') # Load task modules from all registered Django apps. app.autodiscover_tasks() @app.task def test(arg): print(arg) @app.on_after_configure.connect def setup_periodic_tasks(sender, **kwargs): # Calls test('hello') every 10 seconds. sender.add_periodic_task(10.0, test.s('hello'), name='say hello every 10 secs') app.conf.beat_schedule = { 'add-every-12-seconds': { 'task': 'tasks.test', 'schedule': 12.0, # 'args': () }, } and this is how I start celery worker & beat worker: celery -A proj worker -l info celery -A proj beat -l INFO --scheduler django_celery_beat.schedulers:DatabaseScheduler Would appreciate a … -
Access django database on postgresql from independent python script

Getting systemd to use user ENV configs
I am trying to create an LXC container to run a specific Django Application automatically at start. The issue I am having is that getting the Django side of things starting up with systemd was fairly easy, however the application checks ENV variables as well as relies on some Ruby Gems to function. The LXC Template is based on Debian 11. Due to the specific requirements, I run pyenv and rbenv to manage the installed versions for the specific user (django for the purposes of this example). I can get systemd to start the Gunicorn server well enough, but am having an issue that it seems to not pull ENV variables (Not sure yet), nor does it get access to the required Ruby Gems (Confirmed).

Confusion when importing Django' generic class based views
While exploring the reference documentation and some tutorials I have seen the import for Django's generic class based views used in multiple ways: from django.views.generic import TemplateView, ListView Or: from django.views.generic.base import TemplateView from django.views.generic.list.ListView I have tried experimenting with both tactis and they both seem to work, yet the first option seems less correct. Do all the generic CBVs also exist within the generic module a well as the submodules? Can Python import classes from submodules by only importing a higher module? What is actually happening here? Any help would be greatly appreciated! -
