Filtering duplicates in queryset based on UUIDField
I'm running into some problems when pulling a specific list of objects from my db. I'm picking up python/django after quite a bit of time off and feeling pretty rusty. As an exercise I am building an app that allows a group of friends to 'draft' season tickets, eg. take turns selecting which games you want to attend until all the tickets are distributed. The way I've chosen to go about this is to have one db model that contains a dump of all games for an entire season (SportSeason) and a db that contains draft information (TicketDraft). As there will be many rows (to track ticket/game selection) for each draft session, I've created a UUID field for logically grouping the rows that belong to the same draft. models.py class SportSeason(models.Model): year = models.IntegerField(default=None) sport = models.CharField(max_length=10, default=None) home = models.CharField(max_length=10) visitor = models.CharField(max_length=10) date = models.DateTimeField(auto_now=False) class Meta: app_label = 'ticket_draft' class TicketDraft(models.Model): tt_group = models.IntegerField() tt_status = models.CharField(max_length=10) # available, selected tt_owner = models.CharField(max_length=30) gm_date = models.DateTimeField(auto_now=False, null=True) team_home = models.CharField(max_length=10) team_visitor = models.CharField(max_length=10) draft_year = models.IntegerField() ssn_create = models.DateTimeField(auto_now=True) ssn_owner = models.CharField(max_length=30) ssn_status = models.CharField(max_length=10) # active, cancelled, complete ssn_ident = models.UUIDField(default=uuid.uuid4, editable=False) On the home page … -

How to add string var inside php code in python

Django Rest Framework - TypeError: reverse() got an unexpected keyword argument 'request'
I have a number of tests written for a django application, and all tests must pass in order for automated deployment to take place. Unexpectedly, a number of tests began failing, none of which had been touched with the latest commit. The error comes from a serializer that uses django rest frameworks 'reverse' function. # serializers.py from rest_framework.reverse import reverse from rest_framework.serializers import ModelSerializer, SerializerMethodField from my_app.models import ConfigVersion class ConfigVersionMetadataSerializer(ModelSerializer): class Meta: model = ConfigVersion fields = ('id', 'config', 'config_name', 'hyperlink', 'version') hyperlink = SerializerMethodField() def get_hyperlink(self, obj): return reverse( 'versions-list', kwargs={ 'configurations_pk': obj.config.id, 'version_pk': obj.id }, request=self.context['request'] ) All tests that call this serializer now fail with error TypeError: reverse() got an unexpected keyword argument 'request' Django rest frameworks documentation states that 'request' is an included and recommended argument https://www.django-rest-framework.org/api-guide/reverse/. After reviewing the documentation, I have searched for dependency version changes in the build logs to see if there were code changes, but the only dependency update is presumably unrelated (pytz). I'm pretty confused by the source of this issue, since tests were working properly a couple days ago and there don't appear to be any changes to the tests, serializers, views, or required libraries. -
Only able to run tests from dir containing manage.py while using docker shell
I have been trying to run a Django test suite in a running docker container, but using docker exec or even entering the docker shell and running the tests from outside their dir results in the test runner failing to find anything. docker exec -it \<container_name\> <project>/manage.py test doesn't find any tests. However, if I docker exec -it \<container_name\> /bin/bash and then navigate to <project> and run python manage.py test this runs the tests. If I try to do the same (enter shell) but from outside the <project> dir (e.g. python <project>/manage.py test) the test runner finds 0 tests again. I am very confused by these results to say the least, as it seems like these commands should all evoke the same behavior -
How to handle multi-level permissions in Django REST Framework?
I'm attempting to create a DRF API that can handle multi-level permissions. I have Users, Clients, and Brands. Clients can contain one or many Brands. The way I'm trying to get User Permissions to work is a User can have access to one or many Clients. If given access to that Client they will also be given limited access to one or many Brands within that Client. I can't wrap my head around how to manage the permissions on this. Does this need to object instance level permissions? or is there another way to organize it? I'm trying to avoid 3rd party packages, but I have seen several people mention django-guardian. I understand this is a very general question. So I appreciate any type of response on this. Thank you. -

Field 'id' expected a number but got 'None'
I have a little problem. I try to add some values on my table from Mongodb, using django and the admin page. I wrote in models.py (the code is basic, because I am learning and this was the first step from a tutorial that I saw): from datetime import date from django.db import models class activity_stage(models.Model): date = models.TextField() start = models.TextField() stop = models.TextField() distance = models.TextField() calories = models.TextField() steps = models.TextField() In admin.py from django.contrib import admin from .models import activity_stage admin.site.register(activity_stage) But on my admin page, it doesn't attribute to me the index number (list of objects from admin page). I tried to delete the objects, but I receive this error: Field 'id' expected a number but got 'None'. My table from my database it's look like this: Mongodb_collection. I named the class from the models with the same name as the collection from mongo. At the end, I want to import on my page an excel file and I found something that probably can help me. But I don't know how to solve my error. I think that i solve the problem I can after add the objects from admin page in my db. -
Django async model update not being enacted
The SQL update does not seem to be being enacted upon, and no errors are being thrown either. Below is a simplified version of my code. For context, the "choice" field in the model is a Boolean Field with a default of False, and a user may (ideally) change this by sending a JSON package with the "CHOICE" event and "Yes" message. consumers.py import json from channels.generic.websocket import AsyncJsonWebsocketConsumer from asgiref.sync import sync_to_async from .models import Room class Consumer(AsyncJsonWebsocketConsumer): async def connect(self): self.room_code = self.scope['url_route']['kwargs']['room_code'] #Websockets connection code async def disconnect(self): #Websockets disconnect code async def receive(self, text_data): response = json.loads(text_data) event = response.get("event", None) message = response.get("message", None) if event == "CHOICE": room_set = await sync_to_async(Room.objects.filter)(room_code=self.room_code) room = await sync_to_async(room_set.first)() if (not room.choice) and message["choice"] == 'Yes': sync_to_async(room_set.update)(choice=True) #line seems to not be working elif room.choice and message["choice"] == 'No': sync_to_async(room_set.update)(choice=False) #code to send message to group over Websockets #code regarding other events async def send_message(self, res): #Websockets send message code I've tried to only include the relevant code here, but if more is needed please let me know.

How to deal with lots of duplicated data in DB?
I'm currently building a database for a photography project and I'm having troube to decide this: There are about 3 million photographs and I'd like this to keep working even with 15 million. They are stored on disk and with paths in the DB. All of those need a caption, but captions are highly duplicated. On Average about 10 photos have exactly the same caption (same creator, same title, same date). Is it better to create one model? class Photo(models.Model): file = models.FileField() headline = models.CharField() caption = models.TextField() date = models.DateField() created_by = models.CharField() Or should I make 2 models even if it means having to create copies manually when one photo out of a group gets a different caption afterwards? class Photo(models.Model): file = models.FileField() metadata = models.ForeignKey('Metadata') def set_metadata(self, metadata): self.metadata = Metadata.models.get_or_create(metadata) class Metadata(models.Model): headline = models.CharField() caption = models.TextField() date = models.DateField() created_by = models.CharField() The most common task will be to search for pictures based on their metadata. Is creating an extra model and reducing the db table by factor 10 worth it? Or does it just introduce unnessesary complications with no benefits in performance? Thank you for your help! -

django forms.DateInput not responding to dd/mm/yyyy format
currently I'm having issues with getting input validation working as expected with Django DateInput As per my understanding, the default format for DateInput is "%Y-%m-%d" if left untouched, however explicitly setting the format to "%d/%m/%Y" still causes validation errors.

Django RestFramework nested serializer field many=false
