Django- Duplicated queries in nested models querying with ManyToManyField
How do I get rid of the duplicated queries as in the screenshot? I have two models as following, class Genre(MPTTModel): name = models.CharField(max_length=50, unique=True) parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children') def __str__(self): return self.name class Game(models.Model): name = models.CharField(max_length=50) genre = models.ManyToManyField(Genre, blank=True, related_name='games') def __str__(self): return self.name and have a serializer and views, class GameSerializer(serializers.ModelSerializer): class Meta: model = Game exclude = ['genre', ] class GenreGameSerializer(serializers.ModelSerializer): children = RecursiveField(many=True) games = GameSerializer(many=True,) class Meta: model = Genre fields = ['id', 'name', 'children', 'games'] class GamesByGenreAPI(APIView): queryset = Genre.objects.root_nodes() serializer_class = GenreGameSerializer def get(self, request, *args, **kwargs): ser = GenreGameSerializer(data=Genre.objects.root_nodes() .prefetch_related('children__children', 'games'), many=True) if ser.is_valid(): pass return Response(ser.data) so basically the model populated when serialized looks like this The result is what I am expecting but there are n duplicated queries for each of the genre. How can I fix it? Thanks.. here is a paste https://pastebin.com/xfRdBaF4 with all code, if you want to reproduce the issue. -

Why does it show TypeError: UpdateContent() got an unexpected keyword argument 'instance'?
Working on a simple project in Django 3.2 and trying to add an edit button, to edit the content of the page. To do that I did: views.py def UpdateContent(request, pk): contents = todo.objects.get(id=pk) form = UpdateContent(instance=contents) if request.method == 'POST': form = UpdateContent(request.POST, instance=contents) if form.is_valid(): form.save() return redirect('/') context = {'form': form} return render(request, 'html/update.html', context) forms.py class UpdateContent(ModelForm): class Meta: model = todo fields = ['content'] home.html <table class="table table-dark table-hover table-bordered"> <thead> <tr id="tr-table"> <th id="text-left">#</th> <th id="text-center">ITEMS</th> <th id="text-right"><i class="material-icons">&#xe872;</i></th> </tr> </thead> <tbody> {% for all_item in all_items%} <tr> <th id="row" scope="row"> {{ forloop.counter }} </th> <td id="content">{{ all_item.content }}</td> <form action="delete_todo/{{all_item.id}}/" method="post"> {% csrf_token %} <td class="text-right-delete"> <button id="btn-delete" class="btn btn-outline-danger">Delete</button> </td> </form> <td><a class="btn btn-outline-info" href="{% url 'todo:update' all_item.id %}">Edit</a></td> </tr> {% endfor %} </tbody> </table> update.html {% extends 'html/main.html' %} {% load static %} {% block content %} <form action="", method="POST"> {% csrf_token %} {{form}} <input type="submit" name="Submit"> </form> {% endblock %} But when I run the code it shows me this error TypeError: UpdateContent() got an unexpected keyword argument 'instance' Would appreciate any response or suggestion.

How to create a cluster of links, then feed it to scrapy to crawl data from the link based on a depth and crawling strategy set by user from browser
We need help doing this project for our junior year software engineering project. So, our web app is supposed to: Login/Register/Authenticate via google : (we have completed this using Django Allauth.) Then, users will be able to create a cluster of links in a new cluster creating page, there the users will be able to provide information about the clusters. They will provide: cluster name, links to crawl data from, set a depth for each link they provide. (By depth I mean, following the links and webpages associated with the website) Finally, the users will be able to provide a crawling strategy to what to crawl, for this instance(we do not want to crawl any non textual data) : non HTML text data, pdf, doc files. Then, we need to crawl the data and store it in a database or a service (We intend to use Apache Lucene here). So, the data is searchable for the end user from a cluster that they had created. For now, how can we implement all of the things mentioned in point 2? Can someone please help by debunking this step by step on exactly what we need to do? We are a bit … -

Executing a function right before\after revoking a task in celery
For the demonstration, I have a class that does something like this: class Writer: def __init__(self, num): self.num = num def write(self): for i in range(0, num): with open("/outfile", "w") as o: o.write(i) def cleanup(self): # should be executed when write has not finished os.system('rm -rf /outfile') Im using a shared task in celery to execute it like: @shared_task def mytask(): w = Writer(100) w.write() return "Done" Im using django and DRF, and i have an endpoint api that recieves a task_id and revokes the task using revoke(task_id, terminate=True) My goal is to run the cleanup function from the Writer class when the revoke happens. The reason I cannot just run cleanup after the revoke as a regular function is because it needs to access the attributes of its class (in the real senario and not this example), and each class might have a different cleanup function. how can i detect the revoke in mytask() ? Is there a solution using something like try except? Moving the task to a class based task? Have not found anything online or in the docs. Thanks in advance. -

Django - Return all objects in table where attribute A is in list B OR attribute C is in list D

A User can have "followers" which are represented by FollowUser and they can follow another user's goal, which is represented by FollowGoal. I want to return all the posts that the current user which is represented by request.user. I want to be able to get all posts where the creator is someone the current user is following or is a goal the current user is following. As you can see below I generate a list of UUID for both the followees of the current user (people they are following) as well as a list of UUID for the goals the current user is following.
