Django Rest Framework Return List of all parents and their children
I have been going crazy searching for an answer. I have two tables (models) as follows: class DisplayPosts(models.Model): post_id = models.CharField(unique=True, max_length=300, blank=True, null=True) post_url = models.CharField(max_length=300, blank=True, null=True) class Observations(models.Model): post = models.ForeignKey(DisplayPosts, to_field="post_id", on_delete=models.DO_NOTHING, related_name='observations') created = models.DateTimeField(blank=True, null=True) I have created the following seriailzers: class ObservationsSerializer(serializers.ModelSerializer): class Meta: model = Observations fields = '__all__' class DisplayPlostsSerializer(serializers.ModelSerializer): observation = ObservationsSerializer(many=True, source='observations') class Meta: model = DisplayPosts fields = '__all__' I am trying to create a search API to retrieve a list of posts urls and their respective created dates (the relationship between DisplayPosts to Observations is one-to-many). When I retrieve a single post I get all the child observations, but when I try to pull a list based on search terms, the child list is empty. These are my views for single post v.s. list posts: @api_view(['GET', ]) @permission_classes((IsAuthenticated,)) def api_detail_posts(request, post_id): try: display_post = DisplayPosts.objects.get(post_id=post_id) except DisplayPosts.DoesNotExist: return Response(status=status.HTTP_404_NOT_FOUND) if request.method == "GET": serializer = DisplayPlostsSerializer(display_post) return Response(serializer.data) class ApiPostListView(ListAPIView): queryset = DisplayPosts.objects.all() serializer_class = DisplayPlostsSerializer observaation_serializer_class = ObservationsSerializer authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticated,) filter_backends = (SearchFilter, OrderingFilter) pagination_class = PageNumberPagination search_fields = ('post_id', 'post_url') I would appreciate any hints on how I can go about … -

How do I get user input from search bar to display in a page? Django
Django is very challenging and I still need to get used to the code and currently, I just want the search bar to display every time a user input a text and it will display like a title I really don't how to interpret the code to tell that every time the user inputs in the search bar, It is supposed to display the user input on a page like a title. Example: user input in the search bar: cat and it displays cat title Display on the current page: Result search: "Cat" HTML Code <!-- Search Bar --> <form action="{% url 'enc:search' %}" method="GET"> {% csrf_token %} <input class="search" type="text" name="q" placeholder="Search"> </form> In my views.py I only write this code and I don't know what to write it. views.py def search (request): title = request.GET.get("q", "") urls.py urlpatterns = [ path("", views.index, name="index"), path("search/", views.search, name="search"), Right now just a simple display from the search bar input later I will code it in a data search where there is some file to integrate the search but right now I really need some help my brain is cracking. It's kinda sad I mean I know it be a simple … -
Google Autocomplete with Modal Dialog HTML5
Been working with google's autocomplete for a project to use it to find establishments. However whenever I call for it, the pac container div is appended to the body of the html rather than the dialog tag of modal dialog. I have tried a lot of stuff, using promises, messing with focusing. However whenever the page is loaded or whenever you focus into the input box, the first iteration of loading the autocomplete sets the container to the body rather than the input box itself. I've tried also taking it out of the ready and placing it else where, doing a callback into the google url itself. However a simple timeout function does get rid of the pac container, but I would rather like to solve this issue without the use of one. Image of pac container when the dialog screen is loaded up Here is a sample of what my code looks like for the dialog. <dialog id="myDialog> <div class="modal-body"> <input id="searchbox" name="searchbox"/> </div> </dialog> <script> $(document).ready(function () { initAutocomplete(); }); </script> autocomplete.js function initAutocomplete() { const input = document.getElementById("searchbox"); const autocomplete = new google.maps.places.Autocomplete(input); autocomplete.addListener("place_changed", () => { var place = autocopmlete.getPlace(); /* Rest of the code*/ } … -
How to maintain authentication data
I am doing a Vue 3 practice together with Django Rest Framework, what I am trying to do is a token authentication validation, a user logs in, a token is going to be generated, but I run into a problem and it is that when at moment of logging in is done correctly and I am able to obtain the generated token, the problem is that when reloading the page the token is no longer in the vue application, a possible solution that I decided is to make the token save in local storage, but i think it is not the correct solution. This is my Login.vue: <template> <h2>login</h2> <form method="POST" @submit.prevent="sendData" autocomplete="off"> <input type="text" placeholder="Nombre de Usuario" v-model.trim="username" /> <input type="password" placeholder="Contraseña de Usuario" v-model.trim="password" /> <button type="submit">enviar</button> </form> </template> <script> import { ref } from '@vue/reactivity'; import { watchEffect } from '@vue/runtime-core'; export default { setup() { const username = ref(''); const password = ref(''); const token = ref(''); const sendData = () => { fetch(`http://localhost:8000/auth-token/`, { method: 'POST', body: JSON.stringify({ username: username.value, password: password.value, }), headers: { 'Content-Type': 'application/json', }, }) .then((res) => res.json()) .catch((error) => console.error('Error:', error)) .then((response) => { token.value = response.token; }); }; watchEffect(() … -
How to prevent Django caching querysets in memory in a ./manage.py command
I have a ./manage.py command that is made to run as a service in the background. However the memory usage goes up steadily and the script gets killed eventually. By using memory_profiler I found that the memory usage goes up after each query, especially after bulk_create(). I tried putting the results in a variable and setting it to None, also tried django.db.connection.close() after each iteration of the endless loop. Is there a way to tell Django not to cache those queries? -
Make Django Admin Commands run automatically in deployment (apache2)
I am creating an eCommerce site and want to delete rows of the order table after 20 days has passed. And I was successfully able to do that! My code... delete_old_orders.py from django.core.management.base import BaseCommand, CommandError from store.models import Order from datetime import datetime, timedelta class Command(BaseCommand): help = 'Delete objects older than 20 days' def handle(self, *args, **options): Order.objects.filter(order_date__lte=datetime.now()-timedelta(days=20)).delete() self.stdout.write('Deleted objects older than 10 days') In which, just for your information my file location goes as... store/ models.py management/ __init__.py commands/ __init__.py delete_old_orders.py tests.py views.py Every time in order to run it, I need to run the code python manage.py delete_old_orders in the terminal. However, this is in my local machine, when I want this to run every day at 2am in my server, which runs apache2 in Ubuntu. How should I deal with this? Should I alter my config file in the server? Any help would be much appreciated! Thanks! -
Translation from data in database
I implemented a logs system in my Django app, this system, for every action of any user will save informations in the database. Here is the model: class Log(models.Model): user = models.ForeignKey(to=User, on_delete=models.PROTECT) log = models.CharField(max_length=255) type = models.CharField(max_length=50) date = models.DateTimeField(auto_now_add=True) company = models.ForeignKey(to=Company, on_delete=models.PROTECT) My point is on the translation of the log field. For exemple my language is english, it will save in the database "did create a new customer", But if I change the language in french I will obviously get this in english again. Same if a french create a log I will have some logs in french others in english. My problem is there is hundreds of different possibilities for this log field. Is it a way with Django to translate data coming from the database in the templates like with a {% translate %} tag? I was thinking something like having these hundreds possibilities in the translation files and Django translate it directly in the templates? I do have the same problem with the permissions name. Users can give permissions to other users but these permission names are in english. Thanks for your help -
Django served on specific URL - relative urls corrupted
I've deployed my Django (DRF API) project on DigitalOcean apps. The path "/" is used by my static site that uses this API so I set route for this component to "/api" which works correctly. The problem: I go to /api/admin/ and it redirects me to /admin/login but the django is served on /api url so this URL is invalid. Do you know how to make this work? Is there a way to tell django to use absolute URL everywhere? -
Is possible to make unique a field in the database for a foreign key?

Is it that possible? -

Run Dash inside Flask on a template
I started a prototype of a web app on Django using Dash for data visualization, but for comparison purpose I started doing it on Flask too. The main thing is, in Django we have django-plotly-dash that does the interface to connect Django and Dash. With that module, you can embed your Dash app on a single div on your page, which is exactly what I need since im using the website template for the design. I can't seem to find a way to do it in Flask, the only thing I was able to do so far was route it so i cant include it on the app, but on a different page, only with the Dash components. Can anyone help me on how to get the only the div from the Dash app and how to embed it on my base template? Thanks in advance! -

How can I hide fields in auto-generated schemas, or define schemas explicitly?
I am using drf-yasg (Django REST Framework - Yet Another Swagger Generator) to generate docs for my RESTful API, but it's not doing exactly what I want. I thought that setting read_only and write_only attributes to True would hide fields from the documentation as they are omitted from request and response bodies, but this is not the case. I don't see any examples of defining schemas within a decorator, or even just hiding a field, but if I can learn how to do one of those things, I'll be in good shape. Let's go with a basic example: user login. # serializers.py class TokensSerializer(serializers.Serializer): """ Serializes access and refresh tokens for responses to a logged-in user. """ username = serializers.CharField(max_length=64, write_only=True) access = serializers.CharField(max_length=4096, read_only=True) refresh = serializers.CharField(max_length=4096, read_only=True) # ... class LoginSerializer(serializers.ModelSerializer): """ Serializes username, email, password, and tokens to allow for logging in. """ class Meta(): model = User fields = ['username', 'email', 'password', 'tokens'] username = serializers.CharField(max_length=64) email = serializers.CharField(max_length=254, read_only=True) password = serializers.CharField( min_length=8, max_length=64, write_only=True) tokens = TokensSerializer(read_only=True) # ...

WebRTC Peer to Server instead of Peer To Peer
WebRTC Peer to Server instead of Peer To Peer I want to build a WebRTC Video and Voice Calling App. However, I do not want a user to be able to connect directly to another user, as this brings unwanted security risks. So I think it makes more sense to implement the whole thing in such a way that all users (2 in this case) connect to a server, which then distributes the data and the users do not distribute it among themselves, so that, for example, the IP is publicly visible. I don't want that: So even I think this is the normal way you could do it I don't want to, because, how I said there are a lot of security risks that this kind of connection brings with it. I want that: I've heard that Discord, for example, does exactly what I show in the graphic (at least similarly). Can this be implemented? And if so, how? By the way, I used Python Django in the backend. I was wondering whether this could also be done with Python Django Channels. So is there an implementation in Django Channels that I can set up a WebRTC server? Many … -

We need the file upload model to do more stuff, and we're approaching it by create the new model use a data migration to copy data from the old model to the new one delete the old model The data migration works great in local (with local filesystem storage), but fails on a Heroku test server (where the files are stored in an S3 bucket). I get an error message like so: FileNotFoundError: [Errno 2] No such file or directory: '/app/private/recalls/user_74/PDIR_BBUY__9e8c995f-512f-446a-9e99-e95f0de1a4ff.pdf' Relevant code is below Existing "old" model: from django.db import models from myapp.storage_backends import storages_location, upload_file_rename class OldUpload(models.Model): recall_file = models.FileField( validators=[FileExtensionValidator(allowed_extensions=['pdf'], message=RECALL_FILE_EXTENSION_MESSAGE)], storage=storages_location(), upload_to=recall_file_rename ) myapp.storage_backends (based on Local filesystem as a remote storage in Django): import os import uuid from storages.backends.s3boto3 import S3Boto3Storage from django.conf import settings from django.core.files.storage import FileSystemStorage, get_storage_class class PrivateS3MediaStorage(S3Boto3Storage): location = settings.PRIVATE_MEDIA_LOCATION default_acl = 'private' file_overwrite = True custom_domain = False bucket_name = settings.AWS_MEDIA_BUCKET_NAME class PrivateFileSystemStorage(FileSystemStorage): location = os.path.join(settings.MEDIA_ROOT, settings.PRIVATE_MEDIA_LOCATION) def storages_location(): media_storage = None if settings.SITE_NAME == 'LOCAL': base_url …
