Retrieve field values to Django Admin using many to many relationships
I have a simple task: I need to expose player name related to Game in game list (Django Admin). Game object has ManyToMany relationship with Player object via 'players' attribute. The problem is that now I have empty 'players_list' field (empty list means I don't know what to do and just leave it here[enter image description here][1]), though I tried Player.objects.all() and obviously got all players even those who are not bound to particular game. I feel it has simple solution but my brain refuses to work after 55 opened tabs. Thanks in advance! This is my models.py from django.db import model class Player(models.Model): name = models.CharField(max_length=54, default="") email = models.EmailField(max_length=54) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.name class Game(models.Model): name = models.CharField(max_length=254, default="") players = models.ManyToManyField(Player, blank=True, related_name='player_games') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) players_list = [] def __str__(self): return self.name and admin.py from django.contrib import admin from .models import Game, Player class PlayerInline(admin.TabularInline): model = Game.players.through @admin.register(Player) class Admin(admin.ModelAdmin): search_fields = ['name', 'email'] list_display = ('name', 'email', 'created_at', 'updated_at') inlines = [ PlayerInline, ] @admin.register(Game) class AdminAdmin(admin.ModelAdmin): list_display = ('name', 'created_at', 'updated_at', 'players_list') inlines = [ PlayerInline, ] exclude = ('players',) Pic as it looks … -

Serializer for status check
I have a Django project where a restaurant with orders and tables. You can see below the model: class Order(models.Model): STATUS_CHOICES = ( ("in_progress", "In_progress"), ('completed', 'Completed') ) table = models.ForeignKey(Table, on_delete=models.CASCADE, blank=False, null=False, related_name='order_table') user = models.ForeignKey(User, on_delete=models.CASCADE, blank=False, null=False, related_name='order_user') status = models.CharField(choices=STATUS_CHOICES, null=True, max_length=15) I should restrict creating a new order if the table is still in progress.

How to test downloading a path in a Django unittest?
How do you find the fully qualified URL for a static media file hosted by the test server inside a Django unittest? I'm trying to write a test for a custom process that downloads a media file and does some processing on it. The code must be able to download an arbitrary URL, not hosted by me, but for the sake of the test, I'm simply trying to test the download functionality with a local static file. However, attempts by the requests library to access any URLs allegedly being hosted by the test server return the error: HTTPConnectionPool(host='localhost', port=8082): Max retries exceeded with url: /static/mydata.zip (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fe7a2ff8bb0>: Failed to establish a new connection: [Errno 111] Connection refused')) These answers suggest the URL I use can be http://testserver/static/mydata.zip or http:///localhost:8082/static/mydata.zip, but neither of these work. What am I doing wrong? What URL should I use? If I run the dev server from localhost:8000, then I can confirm the URL http://localhost:8000/static/mydata.zip works. To the file itself is setup to be correctly served. However, that URL is not accessible during the unittest. -
Cannot continue the bash script after creating a virtual environment using pipenv
I'm writing a bash script that automates the process of creating a django project and creating some folders and files that is necessary for a django project. The problem here is, when I create and activate the virtual environment using the pipenv shell command, The virtual environment is created and activated but the next command is not executed. The script just waits to exit the virtual environment and when I exit/deactivate the virtual environment, then the next lines of the bash script gets executed. My next line is pipenv install django. When this line is executed, django is installed in the virtual environment and again it waits for the user to exit the virtual environment and when I exit the environment, the next line is executed. But my next line is django-admin startproject myproject when this line is executed, I'm getting the error command not found. Yes I know why I'm getting this error. The environment is deactivated and it can't recognize the django-admin command. Also, I'm running this script as a superuser. I'm using wsl2. my code: mkdir "django_project" cd "django_project" pipenv shell pipenv install django read -p "Enter your project name: " PROJECT_NAME django-admin startproject "$PROJECT_NAME" cd "$PROJECT_NAME" … -

Django Queryset order of evaluation
I have some confusion about how this snippet is evaluated class T(models.Model): person = models.CharField(max_length=10) location = models.CharField(max_length=10) error = models.BooleanField() T.objects.bulk_create([ T(person='P1', location='L1', error=False), T(person='P1', location='L1', error=True), T(person='P2', location='L2', error=False), T(person='P2', location='L2', error=False) ]) for t in T.objects.all().values('person', 'location').distinct().annotate(error=Sum('error')): print(t) When I asked about it on this thread: Combine rows on django queryset, It was explained to me that distinct().annotate(error=Sum('error')): is evaluated as its own unit, but I can't find any proof that this is true. To me, I would expect that the queryset is made to have only distinct values, then it is annotated which would have different effects than what I'm looking for. Any documentation that explains the order of evaluation would be appreciated. -

What I want to have is a field in Level_2 that automatically connects to Level_0 through Level_1. How do I add that field in my Level_2 model? -

One review per user in the current title
I am trying to make so that every user could only post one review per title (product). First idea was to do this through UniqueTogether, but it resulted unsuccessful. So now, I thought to complete it by validate in serializer. Right now I am getting the following error: TypeError: Review() got an unexpected keyword argument 'title'. But if you look at my code below I did not pass title argument to Review(). I even tried to make error on purpose to see what arguments I can pass to Review() and title was not there. django.core.exceptions.FieldError: Cannot resolve keyword 'title_d' into field. Choices are: author, author_id, comments, id, pub_date, score, text, title_id, title_id_id serializers.py class ReviewSerializer(serializers.ModelSerializer): author = serializers.SlugRelatedField( slug_field='username', default=serializers.CurrentUserDefault(), read_only=True ) class Meta: model = Review fields = ('id', 'text', 'author', 'score', 'pub_date') def validate(self, data): title_id = self.context['view'].kwargs['title_id'] author = self.context['request'].user if Review.objects.filter(title_id=title_id, author=author).exists(): raise serializers.ValidationError( 'You cannot post second review on same item.' ) return data models.py class Review(models.Model): title_id = models.ForeignKey( Title, on_delete=models.DO_NOTHING, related_name='reviews' ) text = models.TextField( 'Текст отзыва' ) author = models.ForeignKey( User, on_delete=models.DO_NOTHING, verbose_name='Автор', related_name='reviews' ) score = models.IntegerField( choices=SCORES ) pub_date = models.DateTimeField( 'Дата публикации', auto_now_add=True,) class Title(models.Model): name = models.CharField( max_length=255, …
