How can I link a comment to its corresponding post in Django?
I am building a Django project where I have an index page that lists all posts. The user can click on the name of a post and this will take them to a detail page with the complete post information (date, content, category). This detail page also has a link that will take the user to a form where they can leave a comment. Once the user clicks submit they are supposed to navigate back to the post detail page and the comment is supposed to be there. The issue I am having right now is that the comment is being automatically assigned to the first post in the index list rather than the post the user had visited (I think this may have something to do with the current default setting in my models, but how else can I get the post id?). How can I make it so that the comment is assigned to its correct post? I have tried everything with the models and views but nothing seems to work. Thank you for your help, I think the solution to this might be simple but I can't find it anywhere. Here is my relevant models: class UserPost(models.Model): … -
After upgrading to Django 3.2 my annotations on `ArrayAgg` fields not working
I have a fairly complicated model method that worked perfectly before upgrading to Django 3.2.8. It looks like so: @classmethod def get_inbox_for_user(cls, user: User) -> 'models.QuerySet[ShareRequest]': user_principals_ids = list(user.principals.values_list('id', flat=True)) annotated_share_requests = cls._default_manager\ .annotate( registered_staff_ids=ArrayAgg( 'contact__registered_staffing__staff_user', distinct=True, ) )\ .annotate( primary_registered_staff_ids=ArrayAgg( 'contact__registered_staffing__staff_user', filter=models.Q(contact__registered_staffing__is_primary=True), distinct=True, ) ) filtered_shared_requests = annotated_share_requests\ .filter( (models.Q(primary_registered_staff_ids__isnull=True) & models.Q(registered_staff_ids__contains=[user.id])) | (models.Q(primary_registered_staff_ids__isnull=True) & models.Q(registered_staff_ids__overlap=user_principals_ids)) | models.Q(primary_registered_staff_ids__contains=[user.id]) | models.Q(primary_registered_staff_ids__contained_by=user_principals_ids) ) return filtered_shared_requests Skipping the details, the important part is my annotate statements and further filtering by them. From the example below, you can see that registered_staff_ids results in [None], which looks like a part of the problem: In [39]: annotated_share_requests.first().registered_staff_ids Out[39]: [None] I was able to remedy it by providing an additional filter to my annotate statement, turning that expression into: annotated_share_requests = cls._default_manager\ .annotate( registered_staff_ids=ArrayAgg( 'contact__registered_staffing__staff_user', filter=models.Q(contact__registered_staffing__staff_user__isnull=False), distinct=True, ) )\ ... Which now shows the result as: In [40]: annotated_share_requests.first().registered_staff_ids Out[40]: [] However, the further filtering (specifically __overlap and __contained_by lookups fail, for example: In [56]: annotated_share_requests.values_list('primary_registered_staff_ids', flat=True) Out[56]: <QuerySet [[], []]> # looks great In [57]: annotated_share_requests.values_list('registered_staff_ids', flat=True) Out[57]: <QuerySet [[], []]> # looks great In [58]: user_principals_ids Out[58]: [] # looks great # BUT! In [59]: annotated_share_requests.filter(registered_staff_ids__overlap=user_principals_ids) Out [59]: FieldError: Cannot resolve expression type, unknown … -
How to check unique bulk_create
In Django there is a method get_or_create guaranteeing the uniqueness of the object. But when records for adding a lot more 1000 processing takes a lot of time (as 1000 requests for the creation of objects). I know about bulk_create, but it does not check on the uniqueness of the input attributes of the model. How do I speed up the addition of unique objects to the database? If possible in 1 request. Example model: models.py class Person(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) admin.py # Create only one element (What I want to get) _, created = Person.objects.get_or_create(first_name='Leon', last_name='Mariano') _, created = Person.objects.get_or_create(first_name='Leon', last_name='Mariano') # Create 2 objects with different ID Person.objects.bulk_create(Person(first_name='Leon', last_name='Mariano'), Person(first_name='Leon', last_name='Mariano')) -
Django AJAX befor saving
Hi i'm new to django so any help is appreciated. I have a form that works, the inputs are filled and it is saved in the database. The problem is that I want to create a button "Process with Python" which if it is pressed, it must take an image that was uploaded in an input file and send this photo to get information from the same photo and then return to the form and fill in the rest of what I input with what came out of that function. Someone told me to use ajax for that. but I do not know how. how can I do this? -
Django - POST endpoint to update multiple tables. Return response with all relevant data
I have this POST endpoint below that creates a post. When a post is created the request can be accompanied by video and images. As you can see below a serializer handles the post data outside of images and video, because I need to do validation on the image and video. The response returns the data serialized, but only everything not related to image and video. I'd like the response to also return stuff like image and video url, uuid. How can I do this with the newly created post_obj? view.py @api_view(['POST']) def POST_create_post(request): serializer = PostSerializer(data=request.data) if serializer.is_valid(): try: post_obj = serializer.save() try: if 'images' in request.FILES.keys(): for img in request.FILES.getlist('images'): validate_image_upload(img) Photo.objects.create(post=post_obj, image=img) if 'video' in request.FILES.keys(): vid = request.FILES.get('video') validate_video_upload(vid) Video.objects.create(post=post_obj, video=vid) except ValidationError as e: return Response(dict(error=e, user_message=error_message_generic), status=status.HTTP_400_BAD_REQUEST) except django.db.utils.InternalError as e: return Response(dict(error=serializer.errors, user_message=error_message_generic), status=status.HTTP_400_BAD_REQUEST) return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(dict(error=serializer.errors, user_message=error_message_generic), status=status.HTTP_400_BAD_REQUEST) serializer.py class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = ('creator', 'body', 'uuid', 'created', 'updated_at') models.py class Photo(AbstractBaseModel): post = models.ForeignKey(Post, on_delete=models.CASCADE) image = models.ImageField(upload_to=images_directory_path) @property def image_url(self): return self.image.url class Video(AbstractBaseModel): post = models.ForeignKey(Post, on_delete=models.CASCADE) video = models.FileField(upload_to=videos_directory_path) @property def video_url(self): return self.video.url -
Create custom permission for api view in django
I have a task object and a bid object. i am trying to add the permission in my api view that checks if the the same user that created the task is trying to create a bid for that task. if its the same user it shouldnt be allowed, a bid on the task should only be allowed by other users.

Is it possible to rebuild a single tree?
I can only find documentation for Model.objects.rebuild() which rebuilds all trees. What if I wanted to rebuild a single tree? Is that possible? If it's not possible - does that mean using move_node or insert_node results in rebuilding for all trees? -
File upload stops when it started
I developed a video upload page on a web site. Whe I try to upload a video file smaller than ~100mb everything works perfect but if I try to upload a larger file, the upload process stops at the beginning and continues after a couples minutes. I'm using Hetzner (Ubuntu 18) for my production server and DigitalOcean(Ubuntu 20) for staging. In the staging file uploading process doesn't care the file size. it's works like a charm, but in the production server the upload stops at the begining. Both servers has the same configuration (i handle the deployment and server configs with an Ansible script). They works on the same code, they have same nginx, supervisor and gunicorn configs but in the production server the upload stops. I've tried a lot of different structures in javascript, but nothing changed. Staging works, production fails. The only difference between two server is Ubuntu version but I don't think OS version would be an issue for a simple file upload. Here's my console.log output for the upload progress. You can see there are a lot of time between first and second output. Any ideas? -

How to use Django roles for a SaaS product with an admin portal?
I would try to explain our desired product idea as clear as possible but feel free to ask further questions. So, basically what we want to build is a SaaS product that will be used by multiple clients. For now, we're not interested in custom domains like (cust1.myproduct.com, cust2.myproduct.com) and we will simply be using one database to manage all customers' data. So far so good. Our SaaS product will be sold to enterprise organizations which will then be used by their employees. So for any one customer organization, there are three types of roles that we would like to provide their users, as follows: Admin: An organization's admin that should be able to do all the settings for that particular organization Manager: An organization's manager that can manage the users that are under his/her team Employee: A normal user with bare minimal permissions that can only manage his own data Now, to provision customers for this SaaS product and to set their global settings (e.g. maximum allowed users, license type etc), we also plan to create an admin portal and APIs that will be used by our internal employees only. For this portal, we also want to define roles … -

How to set an owner of created object by default in DRF?

Conditional rendering of the Bookmark Button in React + Django Rest Framework
Hello? I am working on an ecommerce project and I want to render the Bookmark button conditionally to display that if a user saves a product the Bookmark button innerHTML changes from "Not Saved" to "Saved" in the frontend (React). The backend (Django) is working and user's bookmarks are being saved in the backend. In React I have used the following approach. {product.bookmarks && product.bookmarks.find(bookmark => bookmark.id === user.id) ? <p>Saved</p> : <p>Not Saved</p>} So it matches the Bookmark ID with the logged User's ID. The button is working and if a user saves a product it returns "Saved" in the frontend and if not saved it returns "Not Saved". Is this the best approach to use or there's a better method? I have also tried this approach in Django and it returns the data but I'm not sure how to use the data in React to render the button. @api_view(['POST']) @permission_classes([permissions.IsAuthenticated]) def add_bookmarks(request, id, *args, **kwargs): saved = bool product = get_object_or_404(Product, id=id) if product.bookmarks.filter(id=request.user.id).exists(): saved = False product.bookmarks.remove(request.user) else: saved = True product.bookmarks.add(request.user) data = { 'saved': saved } print(data) return Response(data, status=status.HTTP_200_OK) -
Django: counts forms submitted
What I'd like to do with my model is to have and HTML page where to show my users how many question form they have submitted and how much they are still missing (I've five in my original template here I'm repoprting only two) and also for the admin to see how many users in total submitted the forms so this is my code: **HTML** {% extends "base.html" %} {% block content %} <main> <div class="container"> <div class="table-responsive text-nowrap"> <h2>Submission</h2> Total: {{ quest_done }}/2 {% if user.is_superuser %} Total Question 1: {{ question1_count }} Total Question 2: {{ question2_count }} {% endif %} </div> </main> {% endblock %} **question.models.py** class QuestionOne(models.Model): user = models.OneToOneField(UserInformation, blank=True, null=True, on_delete=models.CASCADE) question_1a = models.CharField(max_length=250, choices=point) question_2a = models.CharField(max_length=250, choices=point) question_3a = models.CharField(max_length=250, choices=point) quest_1_submitted = models.BooleanField(default=False) def __str__(self): return self.name + '_question_1' class QuestionTwo(models.Model): user = models.OneToOneField(UserInformation, blank=True, null=True, on_delete=models.CASCADE) question_1b = models.CharField(max_length=250, choices=point) question_2b = models.CharField(max_length=250, choices=point) question_3b = models.CharField(max_length=250, choices=point) quest_2_submitted = models.BooleanField(default=False) def __str__(self): return self.name + '_question_2' **question.views.py** quest_done = 0 quest_count = 0 def question_one(request): if request.method == 'POST': form = QuestionOneForm(request.POST, request.FILES) if form.is_valid(): questionnairename.quest_1_submitted = True question1_count = QuestionOne.objects.all().count() form.instance.user = request.user form.save() messages.success(request, 'Form submitted') if … -
?: (urls.E006) The STATIC_URL setting must end with a slash
I was trying to migrate my new schema for my database in django when I got this error: AttributeError: 'PosixPath' object has no attribute 'startswith' I looked online and I saw that if you wrap your paths with str(), the error goes away. But then I got this error: ?: (urls.E006) The STATIC_URL setting must end with a slash. I tried doing the obvious thing and changing STATIC_URL = BASE_DIR.parent / "svelte" / "public"(what I think was causing the error) That didn't work, so I tried STATIC_URL = BASE_DIR.parent / "svelte" / "public" /. That also didn't work, so know I need help.
