Django channels creating two instances instead of one
I am using Django channels for real-time app purposes, more specifically to make real-time comments. And then I will explain my situation ... When someone sends a comment, they are supposed to create one and only one object in the database. The problem here is that when two or more users are connected to the same layer, the database creates two objects instead of just one. I have already reviewed and revised my code and I cannot find where I messed up. I hope I was able to explain my problem well so that you can help me! Here is my database model: class Comentarios(models.Model): sender = models.ForeignKey(User, on_delete = models.CASCADE, null = False, blank = False) tarefa = models.ManyToManyField(Tarefa) content = models.TextField(max_length = 255, null = False, blank = False) time_created = models.TimeField(auto_now_add = True) And here is my consumers.py: from channels.generic.websocket import AsyncWebsocketConsumer import json from channels.db import database_sync_to_async from app.models import Comentarios, Tarefa from django.contrib.auth.models import User from django.core import serializers class WSConsumer(AsyncWebsocketConsumer): async def connect(self): self.room_name = self.scope['url_route']['kwargs']['id'] self.room_group_name = 'chat_%s' % self.room_name self.user = self.scope['url_route']['kwargs']['user_id'] print("Connected!") print(self.scope['user'].__dict__) await self.channel_layer.group_add( self.room_group_name, self.channel_name ) await self.accept() @database_sync_to_async def db_comentario(self, message): user_sender = User.objects.get(id = self.user) tarefa = … -

Jquery returns an error where it cannot find the property of an objects (Django)
When I changed the import method I got an error on a live search. This is the JQUERY code I'm using. The error I'm gettin is the blogpost['title'] is empty. I've read that it might be due to the name blogpost being the overall container, so it's not actually a single blogpost but all the blogpost, but I don't know how to fix this. I think the most helpful would be someone taking a look at the rdata and the json error. Thanks! <script> var data = '{{qs_json}}' data = data.replace(/&quot;/g, '"'); data = data.replace(/(?:\r\n|\r|\n)/g, ''); console.log(data) rdata = JSON.parse(data) console.log(rdata) const input = document.getElementById('search_form') let filteredArr = [] input.addEventListener('keyup', (e) => { jsbox.innerHTML = "" filteredArr = rdata.filter(blogpost => blogpost['title'].toLowerCase().includes(e.target.value.toLowerCase())) if (filteredArr.length > 0) { filteredArr.map(blogpost => { jsbox.innerHTML += ` <div class="col mt-5 ml-1"> <a href="blog/${blogpost.slug}" style="text-decoration: none"> <div class= "card"> <div class='blogpost_image_container'> <img src="${blogpost.image}" class="card-img-top" alt="blogpost image"> </div> <div class="card-body"> <h5 class="card-title">${blogpost.title} </h5> <p class="card-text"> ${blogpost.subtitle} </p> <span id="category_badge" class="badge rounded-pill bg-warning text-dark"> ${blogpost.category} </div> </div> </div > </a> ` }) } else { jsbox.innerHTML = `<div class= "col mt-5 ml-1"> <h5 class="card-title"> No Matches Found! </h5></div >` } }) </script> However the console logged Rdata shows … -

eb deploy not able to resolve django application dependencies in requirements.txt
Here is the summary and order of events that happen when I deploy my code on AWS using eb deploy. The ec2 instance is unable to resolve the dependencies for the package "flake-logging-format 0.6.0" and the deployment fails with the error log shown below. I deploy after removing the dependency "flake-logging-format 0.6.0" from requirements.txt and it gets deployed successfully and the server starts running. I deploy again after re-adding the dependency "flake-logging-format 0.6.0" and this time it also gets deployed successfully and the server starts running. My question is: Why does the deployment fail in the first step, and why does it work after executing steps 2 and step 3, overall there is no difference in requirements.txt at step 1 and step 3.

What is the correct way of creating APIs which contain multiple tasks?
Any help would be appreciated. I am creating a small application which has facebook type feature of sending friend requests and adding friends. So I wanted to know the correct way to implement this keeping REST architecture in mind. When a person accepts a friend request, I need to perform 2 functions, firstly add that person as a friend in my model Friend and delete the friend request from the model FriendRequest. So as of now I have created 2 APIs, one to add Friend through a POST request and another to delete Friend Request through a DELETE request. Issue with this method is that, in the frontend we will have to make 2 synchronous requests and if the network is lost between these requests it will obviously create problems. Thank you in advance. -

Get Celery task to sleep and then restart at the back of the worker queue
If I had a celery task that was the following - @app.task def greetings(firstname, lastname): print("hello" + firstname + lastname) If I then wanted that task to sleep for 5 minutes before restarting would I use celerybeat? I want the restarted task to just go to the back of the workers queue also. -
Page not found after submitting form django
I have a comment model in my forum and when I try to submit it it says "Page not found - /POST?csrfmiddlewaretoken". views.py: @login_required def comment(request, pk): if request.method == 'POST': form = CommentCreationForm(data=request.POST) if form.is_valid(): comment.post = get_object_or_404(Post, pk=pk) comment.writer = request.user comment = form.save() messages.info(request, 'comment published') return JsonResponse({'message': 'Thank you for your comment'}, safe=False) else: form = CommentCreationForm() html file: <form action="POST"> {% csrf_token %} {{ form.text.errors }} <label for="{{ form.text.id_for_label }}">comment:</label> {{ form.text }} <button id="comment" type="submit">comment</button> </form> {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %} By the way, can you help me make it in ajax? -
How can I have two POST requests in the same view without getting MultiValueDictKeyError?
my view originally worked as a search engine (in which the POST request returns the search results) but I added a function so that the user can 'favorite' any item that's returned so that it'll be added to their profile. However, since I have two different post requests, the second request (which is the one to favorite the item) returns MultiValueDictKeyError since it's still referencing the first post request. How can I make my view take both different requests? This is the view code (def anime is the one not working): def search(request): animes = [] if request.method == 'POST': animes_url = 'https://api.jikan.moe/v3/search/anime?q={}&limit=6&page=1' search_params = { 'animes' : 'title', 'q' : request.POST['search'] } r = requests.get(animes_url, params=search_params) results = r.json() results = results['results'] if len(results): for result in results: animes_data = { 'Id' : result["mal_id"], 'Title' : result["title"], 'Episodes' : result["episodes"], 'Image' : result["image_url"] } animes.append(animes_data) else: message = print("No results found") for item in animes: print(item) context = { 'animes' : animes } return render(request,'search.html', context) def anime(request): if request.method == "POST": anime_id = request.POST.get("anime_id") anime = Anime.objects.get(id = anime_id) request.user.profile.animes.add(anime) messages.success(request,(f'{anime} added to wishlist.')) return redirect ('/search') animes = Anime.objects.all() return render(request = request, template_name="search.html") This is the … -
Prevent Inline Showing When Adding a New Object
I have two one-to-one related models in Django. Simplified version as follows: class User(models.Model): name = models.CharField(max_length=40) class Profile(models.Model): age = models.IntegerField() user = models.OneToOneField(User, on_delete=models.CASCADE) I have used signals to automatically create a profile automatically when a new user is created. I have also created a ProfileInline and included it in my UserAdmin as follows: class ProfileInline(admin.TabularInline): model = Profile can_delete = False class UserAdmin(admin.ModelAdmin): list_display = ('name',) inlines = [ProfileInline,] The problem I am facing is that when a new User is being created in the admin module, and the person creating the new user also populates the field for the inline on the same page, an error is generated while saving because both the signals module and the admin are trying to create a new Profile. Is there any way to prevent the ProfileInline from showing in the UserAdmin when adding a new User? Thanks. -
