Prefetching or Selecting a single model from a ManyToMany field for use in a Serializer
We have a model with a ManyToMany through table like such class Person(models.Model): name = models.CharField(max_length=50) class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField( Person, through="Membership", through_fields=("group", "person"), ) class Membership(models.Model): group = models.ForeignKey(Group, on_delete=models.CASCADE) person = models.ForeignKey(Person, on_delete=models.CASCADE) On our Group view we would like to create a single-model access to the Membership model based on request.user so that our serializer can access fields of the pivot table like class GroupSerializer(serializers.ModelSerializer): user_name = serializer.CharField(source='memberships.user.name') I have tried a query such as Group.objects.filter(user=request.user).annotate( request_user_membership=Subquery(Membership.objects.filter(group_id=OuterRef('id'), user_id=request.user.id)) ) so that I might be able to reference the single object like class GroupSerializer(serializers.ModelSerializer): user_name = serializer.CharField(source='request_user_membership.user.name') however it does not seem that you can use subqueries like this. This seems like a common problem so I was hoping you all might have some ideas. Any help is greatly appreciate -

Django: how select items that do not have referencies from other items?
Assume, we have a model: class Critters(models.Model): name = models.CharField() parent = models.ForeignKey(Critters, blank=True, null=True, on_delete=models.CASCADE) In begin was some critters: id Name Parent == ======== ======== 0 Critter1 1 Critter2 2 Critter3 And then, some critters made a children: id Name Parent == ======== ====== 0 Critter1 1 Critter2 2 Critter3 3 Child1 0 4 Child2 1 I wand make a request for select all parents without childrens (i.e. no creatures with parents, and no parents with existing childrens): id Name Parent == ======== ====== 2 Critter3 I think it can be done with annotate and exact django's directives, but i'm dubt in stick how exactly i can make this...

Django 4 Running some python codes/files outside views for specific request and returning the parameters as context before rendering template
I am relatively new to Django, while I am fine with loading static pages etc, I have an issue with complex dynamic content. I am designing a quiz, when a user answers a question, I would like to log some parameters into the database (correct or wrong, time taken for the response, etc). When the user clicks next, I want to analyse the data from the answer to the previous question, apply an algorithm and select the question and its parameters as context to the template so that the next question is loaded. So far, I have created a config.py that lets me take the parameters (context) from quiz.py and use them in views.py. Both config.py and quiz.py are in the main folder of the Quiz App. The problem I have is how to read and analyse the user session and data in my quiz.py so that I could apply the algorithm based on the user's previous answers and performance on the database. I have looked at many forums, videos, etc but not even sure if I am on the right path. I have looked at Middleware, Threading, using Celery, etc and I cannot get the user data from "request" … -
Django Define serializer for Model in relation using Foreign Key

How to move django models from one app to another
So we have a django backend already in production with a reasonable amount of data.During the initial stages, we had a small team of two and we were also working with deadlines. I would also admit we were beginners and didn't follow best practices.Because of this,all our models were defined in one app.Now the project is messy and I also learnt it is not a good practice to have many models in one app.Now my question is,how can we move some of this models to new different apps in our project without running into migration issues or worse loosing the data? Our models also have a lot of relationships.Just for reference,we are using postgres databases. I have reasearched the internet for solution but haven't found a comprehensive approach to doing it.Most of the answers here also seems outdated.Some people also recommend to use south which is deprecated. -

How to add a Bootstrap modal to edit the item selected?
I'm a beginner Django programmer and I have this project that is about creating timelines in which you can add events, and these events will show up in their timelines along with either a countdown to when it will start, a counter of how long ago it ended, or a countdown of how much time it has until it ends if it's an ongoing event. Here's the project's repository: https://github.com/high-rolls/timely So far I was able to handle timeline creation, edit and deletion, as well as event creation and displaying timelines and events within a timeline. But I started having trouble when trying to allow the user to edit an event on the list, what I wanted to do was display a Bootstrap modal, like the one I already display when adding a new event but for editing one, and I wanted to have only a single edit modal element at the bottom of the page (instead of adding a modal after each event's div). Should I do this with JavaScript to dynamically pass the ID of the selected event and fetch the data of that event to fill up the modal's form? I am also confused whether I should use … -

Django - OGP Image url preview works inconsistently
I've been struggling with this issue for the past few days now and I still can't find the root cause of it so here it goes: I have a Django blog for which I would like to be able to share links in social media apps such as Whatsapp, Telegram and Signal and I would like these links to have previews containing images of the blog post that the user is sharing.

"Definition of service not found" error when using pg_service.conf file with Django and PostgreSQL
I'm trying to use a pg_service.conf file to manage database connections in my Django application, but I'm running into an error when trying to connect to the database using the named service. Here's what my DATABASES setting in Django looks like: python DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'OPTIONS': { 'service': 'my_service' } } } And here's what my pg_service.conf file looks like (located at /etc/postgresql-common/pg_service.conf): ini [my_service] host=localhost port=5432 user=my_user password=my_password dbname=my_database However, when I try to run my Django application, I get the following error: psycopg2.OperationalError: service file "/etc/postgresql-common/pg_service.conf" not found The above exception was the direct cause of the following exception: django.db.utils.OperationalError: definition of service "my_service" not found I've checked that the pg_service.conf file exists in the correct location and has the correct permissions, and I've also verified that the service name in my DATABASES setting matches the service name in pg_service.conf.
