Django - DeleteView with pk. No Posty matches the given query
Heeey I have a problem with get_success_url. Namely I would delete a comment from post and then should go back to the page with the post. On this moment have i "No Posty matches the given query." I dont have idea how i can resolve this. I know how to reverse on page with no pk ;( Models class Posty(models.Model): title = models.CharField(max_length=250, blank=False, null=False, unique=True) sub_title = models.SlugField(max_length=250, blank=False, null=False, unique=True) content = models.TextField(max_length=250, blank=False, null=False) image = models.ImageField(default="avatar.png",upload_to="images", validators=[FileExtensionValidator(['png','jpg','jpeg'])]) author = models.ForeignKey(Profil, on_delete=models.CASCADE) updated = models.DateTimeField(auto_now=True) published = models.DateTimeField(auto_now_add=True) T_or_F = models.BooleanField(default=False) class Meta: verbose_name_plural = 'Posty' def __str__(self): return str(self.title) def save(self, *args, **kwargs): if not self.sub_title: self.sub_title = slugify(self.title) super(Posty,self).save(*args, **kwargs) def get_absolute_url(self): return reverse('home:detail_post', kwargs={"id":self.id}) Views class delete_post_comment(DeleteView): model = CommentModelForm() template_name = 'delete_comment_from_post.html' def get_object(self): id_ = self.kwargs.get("id") return get_object_or_404(Posty,id=id_) def get_success_url(self): return reverse('home:detail_post') Urls urlpatterns = [ path('', home, name='home'), path('forum/', create_post_and_comment, name='forum'), path('delete_post/<int:pk>/', delete_post_view.as_view(model=Posty), name='delete_post'), path('update_post/<int:pk>/', update_post_view.as_view(model=Posty), name='update_post'), path('delete_post_comment/<int:pk>/', delete_post_comment.as_view(model=CommentPost), name='delete_post_comment'), path('update_post_comment/<int:pk>/', update_post_comment.as_view(model=CommentPost), name='update_post_comment'), path('detail_post/<int:pk>/', contact, name='detail_post'), path('testuje/<int:pk>/', contact, name='test') Forms class CommentModelForm(forms.ModelForm): content1 = forms.CharField(widget=forms.Textarea(attrs={})) class Meta: model = CommentPost fields = ('content1',) -
NGINX-WSS connection failing but WS connection works
I am having trouble implementing wss connections in my app over port 443. When connecting to my app over port 80 I able to connect to the socket(ws connection). my app works fine with HTTPS requests(can log in and request data) but cannot handle wss properly.

Django Rest Framework save multiple serializers in a celery task
Am using Django rest framework, Celery, and RabbitMQ for my aplication. I have a task that does some data processing and saves the results as objects in my Django application. The task has two different results that need to be saved, so two model serializers are needed. The problem is that when the task is performed only one of the models is being saved. I tried the method while it was not a celery task and it worked perfectly, and i don't know what changes when it is run as a task that it won't work any more. this is the code runned in the task: def createMBGSimulations(petition_id): ... Data process ... prices = s_Q.tolist() lists_ci = cis.tolist() serializer = serializers.PriceSerializer(data={}) serializer_ci = serializers.ConfidenceIntervalSerializer(data={}) if serializer.is_valid(): petition = models.Petition.objects.get(pk=petition_id) serializer.save(prices=prices, petition=petition) if serializer_ci.is_valid(): serializer_ci.save(ci=lists_ci, petition=petition) petition.clean() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) -
Django REST Framework: handle exception for custom permission class
I built a custom permission class in Django that verifies the remote IP address of the request. If the request IP is one that's allowed, the has_permission class returns True, otherwise it returns False and the view responds with status code 403.. class isVerifiedServer(permissions.BasePermission): def has_permission(self, request, view): ip_addr = request.META['REMOTE_ADDR'] return ip_addr == some_verified_ip But I want the view to return 404 when this test fails, which is what the server responds with by default when a request is sent to a non-existent URL endpoint. I want to do this to make sure no one can figure out what a valid endpoint is. DRF documentation says the following about changing the exception response of a custom permission class: Custom permissions will raise a PermissionDenied exception if the test fails. To change the error message associated with the exception, implement a message attribute directly on your custom permission. Otherwise the default_detail attribute from PermissionDenied will be used. Similarly, to change the code identifier associated with the exception, implement a code attribute directly on your custom permission - otherwise the default_code attribute from PermissionDenied will be used. I've tried setting many attributes to achieve this, but the response is still always … -
Cannot get autocompletion on Django Model Manager in PyCharm
I'm trying to use autocompletion to get methods like filter, count, create, etc. in PyCharm, but I can't seem to grab them from the objects attribute. It seems like this specific attribute is not working - since PyCharm provides autocompletion for the class itself, for example, just not objects. I've tried refreshing the virtual environment as well, but it seems like it might just not be a supported features. It doesn't autocomplete in either Pycharm 2020.3 or Pycharm 2021.2., or in abstract or concrete classes. -

Pulling profile data from Google OAuth2 for custom Django User Model

Once a certain user is signed in with their Google Account, I would like to extend the profile using a Django User (or AbstractBaseUser) Model with more fields such as some pictures or favorite colors. However, I am lost on how and where to implement this in my code. Any help would be greatly appreciated! -
Django manage.py - differentiate runserver and/or actual server running from other command contexts?
Suppose I have some code in one of the urls.py that really shouldn't be run during a lot of the Django management/maintenance commands.

How do I run Django test using a CustomUser(AbstractUser) class instead of default AbstractUser for correct ForeignKey assignment during test?
I have a CustomUser model in 'accounts' app that overrides Django's default auth.User: class CustomUser(AbstractUser): age = PositiveIntegerField(null=True, blank=True) user_type = CharField(max_length=8, null=False, choices=[('customer', 'Customer'), ('owner', 'Owner')]) And another app 'ecommerce' with a model Product (abbreviated for brevity) with a ForeignKey to the CustomUser field above: class Product(Model): name = CharField(max_length=255, null=False, blank=False) [...] seller = ForeignKey(CustomUser, on_delete=CASCADE, related_name='products') When I create the new Product, I'm using form_valid() function on the model to set the user based on the request that Django uses via CreateView. This works when I'm working in a browser, however does not when I am trying to validate my ProductCreateView through a test a script: views.py class ProductCreateView(CreateView): model = Product [...] def form_valid(self, form): form.instance.seller = self.request.user return super().form_valid(form) test.py def test_product_create_view(self): response = self.client.post( reverse('ecommerce_post_product'), { 'name': 'newProduct', 'price': 2.99, 'category': 'newCategory', 'quantity': 100, 'shipping': 'standard', }) # error happens here self.assertEqual(response.status_code, 302) # test does not reach this line When I run my tests, this test always throws an error stating, ValueError: Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x7fbce54f0040>>": "Product.seller" must be a "CustomUser" instance."

What is the best method for retrieving all objects associated with a foreign key using Django rest_framework?
I have a React application where I'm using Django+REST for the API and backend. On the frontend, I send a POST request to create a Job model and run the job. In the response, I retrieve the ID of the new Job object. axios.post('http://127.0.0.1:8000/api/jobs/', query) .then((resp) => { setActiveJobs([...activeJobs, resp.data.id]) }, (error) => { console.log(error) }) When the job finishes running, it creates multiple Result objects associated to it by a ForeignKey. These are my two models: class Job(models.Model): query = models.CharField(max_length=255, blank=True, null=True) status = models.CharField(max_length=10, blank=True, null=True) class Result(models.Model): job = models.ForeignKey(Job, blank=False, null=False, on_delete=models.CASCADE) result_no = models.IntegerField(blank=False, null=False) ... more fields I'm having trouble using rest_framework in Django to send a GET request using the Job's ID to get a list of all the Result associated with it. I've tried to give custom implementations for retrieve(self, request, pk=None) and get_queryset(self) but so far my approaches have not worked. Ideally, I'd like to call a url such as localhost:8000/api/results/15 where 15 would be the object id of the Job that was created. If there are 5 Result objects that have the job ForeignKey field set as the Job object with an ID of 15, a list of those … -
Updating a mysql row via Django
I have a basic working app that displays the contents of a table and also allows you to insert new rows. My next step is to allow updating of existing rows, and I'm running into some mental roadblocks that I think are caused by my basic understanding of how components of a django project interact with each other (views,models,templates,etc.). I currently have this views.py file within my "enterdata" app. The "showform" function allows you to create a new record within the db. What I am working on is the "updatedata" function below it, which eventually I would like to have the ability to select a row via the UI and then update. But for now, I am hardcoding the primary key and the value just to get the basics going. I am getting hung up on how I can add an "update" button to my existing HTML template that I'm already using for the ability to create rows. It trips me up that it's not easy to see how a button on an HTML form is mapped to a function in a view. Coming from a Visual Basic background where this was clear, I'm struggling a bit. How can I … -

Get array of images from JS to Django template
I want to show random images every time someone enters my art gallery or on refresh and change the images on my art gallery every 30 seconds. I have everything set up correctly in Django. In JS I have created a list of jpeg files. I want to pick a random picture. I am not sure how to use the Django syntax {% %} in JS nor do I know if it is possible. There is some code I found and it does something like this: //Add your images, we'll set the path in the next step var images = ['banner-1.jpg', 'banner-2.jpg', 'banner-3.jpg', 'banner-4.jpg]; //Build the img, then do a bit of maths to randomize load and append to a div. Add a touch off css to fade them badboys in all sexy like. $('<img class=" class="fade-in" src="images/' + images[Math.floor(Math.random() * images.length)] + '">').appendTo('#banner-load'); </script> However, I would like use the Django syntax or something similar so I don't have to specify the path to the images. Also, is there a way to tie this to a timer that will continue to show random pictures for my art gallery? Thanks! -

Pre-signed URLS on Vultr Object Storage using boto3
I have been working with Vultr for quite a while, and when I wanted to store some media files, I thought of AWS'S S3, and Vultr provides an S3 compatible service (Object Storage). I can use s3cmd CLI to play with the service, and they point to use boto3 for interacting with the S3 service. I wanted to have my objects have signed URLs, but I believe boto3 has amazonaws.com as the hostname as a constant somewhere in the code and that cannot be changed from configs as below in below: import logging from django.conf import settings import boto3 from botocore.exceptions import ClientError from premarket.models import PreMarket from .models import SupervisorLogs class Supervisor(): def __init__(self) -> None: self.bucket_name = settings.BUCKET_NAME self.link_expiration = settings.ONE_WEEK self.queryset = PreMarket.objects.all() # Generate a presigned URL for the S3 object self.s3_configs_object = settings.AWS_S3_CREDS self.s3_client = boto3.client('s3', **self.s3_configs_object) def sign_objects(self): for obj in self.queryset: try: presigned_url = self.create_presigned_url(obj.video_url) obj.presigned_url = presigned_url obj.save() except Exception as e: self.supervisor_logs(level="ERROR", message=e, description=e) logging.error(e) self.supervisor_logs(level="COMPLETE", message="Object URL signing has completed", description="Object URL signing has completed") def create_presigned_url(self, object_name): """Generate a presigned URL to share an S3 object :param object_name: string :return: Presigned URL as string.

How to create a button to change a text in my html with data coming from Django's models.py?

Below the phrase, there is a button that I would like to change the phrase to some other phrase coming from a variable declared in models.py and which contains several phrases that were registered through Django's admin panel. This is my models.py file: from django.db import models class Base(models.Model): criado = models.DateField('Criado', auto_now_add=True) modificado = models.DateField('Atualização', auto_now=True) ativo = models.BooleanField('Ativo', default=True) class Meta: abstract = True class Frase(Base): frase = models.CharField('Frase', max_length=100) dica = models.CharField('Dica', max_length=200, default='-') class Meta: verbose_name = 'Frase' verbose_name_plural = 'Frases' def __str__(self): return self.frase This is my views.py file: from django.views.generic import TemplateView from .models import Frase class IndexView(TemplateView): template_name = 'index.html' def get_context_data(self, **kwargs): context = super(IndexView, self).get_context_data(**kwargs) context['frases'] = Frase.objects.order_by('?').all() return context This is my index.html <div class="container px-4 px-lg-5 h-100"> <div class="row gx-4 gx-lg-5 h-100 align-items-center justify-content-center text-center"> <div class="col-lg-8 align-self-end"> <h1 class="text-white font-weight-bold" id="frase">{{ frases|first }}</h1> <hr class="divider" /> </div> <div class="col-lg-8 align-self-baseline"> <a class="btn btn-primary btn-xl" onclick="nova_frase()">Nova frase</a> </div> </div> </div> (...) <!--rest of the html code--> …
