"detail": "method \delete\ not allowed" django
I made a view that can use put, delete request using modelviewset and mapped it with url. I have clearly made it possible to request put and delete request to url, but if you send delete request to url, I return 405 error. What's wrong with my code? Here's my code. views.py class UpdateDeletePostView (ModelViewSet) : serializer_class = PostSerializer permission_classes = [IsAuthenticated, IsOwner] queryset = Post.objects.all() def update (self, request, *args, **kwargs) : super().update(request, *args, **kwargs) return Response({'success': '게시물이 수정 되었습니다.'}, status=200) def destroy (self, request, *args, **kwargs) : super().destroy(request, *args, **kwargs) return Response({'success': '게시물이 삭제 되었습니다.'}, status=200) feed\urls.py path('post/<int:pk>', UpdateDeletePostView.as_view({'put': 'update', 'delete': 'destroy'})), server\urls.py path('feed/', include('feed.urls')), and error "detail": "method \delete\ not allowed" -
Hwo to structure css files in django python?
for better overview I created subfolders in the static folder of my django project with css files for each page like this: static --- landing_page -------landing_page.css -------landing_page_mobile.csss If I want to use all the css files I need to import a lot of files in the base.html file like: <link rel="stylesheet" href="{% static '/css/global.css' %}"> <link rel="stylesheet" href="{% static '/css/landing_page/landing_page.css'%}"> <link rel="stylesheet" href="{% static '/css/main_page/main_page.css'%}"> <link rel="stylesheet" href="{% static '/css/landing_page/landing_page_mobile.css'%}"> Is there any other way to keep the css structured without the need of 1000 imports in the base.html ? How are you structuring your projects ? -
gunicorn <HaltServer 'Worker failed to boot.'
I have read the posts with similar tittles and nothing seem to solve my issue. We are running a django app with gunicorn, supervisor and nginx for a few months now without any problems.

Serve TLS certificate dynamically per Django view instead of via nginx/gunicorn
I'm using Django's request.get_host() in the view code to differentiate between a dynamic number of domains. For example, if a request comes from www.domaina.com, that domain is looked up in a table and content related to it is returned. I'm running certbot programmatically to generate the LetsEncrypt certificate (including acme challenge via Django). I store the cert files as base64 strings in PostgreSQL. That works perfectly fine, but I can't figure out how to 'apply' the certificate on a dynamic per-domain basis. I know that this is normally done using TLS termination, nginx or even in gunicorn. But that's not dynamic enough for my use-case. The same goes for wildcard or SAN certificates (not dynamic enough) So the question is: Given I have valid LetsEncrypt certs, can I use them to secure Django views at runtime? -
How to do location based query with simple Django filter?
I've saved user's coordinates in the User model. Post model has latitude, longitude and radius field. Only the users in that vicinity(of Post) will be able to see that post. I don't know how to use filter() here so I used the following approach: post=Posts.objects.all() for a in post: distance= geopy.distance.geodesic((lat1,lng1), (a.latitude, a.longitude)).km print(distance) if distance < a.radius: p.append(a) else: continue Here, lat1 and lng1 are the coordinates of current User. Suggest if there is any better way as this seems very inefficient. -
Annotate with django: send form with ajax, render div with new item and restart
I want to create a simple annotation web app, where I want the user to see one item, annotate with a simple radio form, submit the form, see the next item, annotate, and so on. I'm using Django but I'm not able to make it work. The problem is that it works with first submission but with the second one gives the error: Forbidden (403) CSRF verification failed. Request aborted. This is what I have for testing: An app called anotar with the following urls.py: app_name = 'anotar' urlpatterns = [ path('',views.dashboard,name = 'dashboard'), ] in views.py: def dashboard(request): template = 'anotar/dashboard.html' tweet_id = '1323646485200850945' if request.is_ajax(): print("AJAX") # I will save the anotation here and pass the another id for new anotation template = 'anotar/tweet.html' tweet_id = '1324423455002005505' html = render_to_string(template,{'tweet_id':tweet_id}) return JsonResponse({'html':html},safe=False) return render(request, template, {'tweet_id':tweet_id}) Then, the dashboard.html: {% extends 'base.html' %} {% load static %} <div id="teste-include"> {% include "anotar/tweet.html" %} </div> {% block domready %} $('#post-form').on('submit', function(event){ event.preventDefault(); console.log("form submitted!") // sanity check save_anotation(); }); function save_anotation() { console.log("create post is working!") // sanity check console.log($('.form-check-input:checked').val()) $.ajax({ url :'{% url "anotar:dashboard" %}', // the endpoint type : "POST", // http method data : { option … -
Django multiple boolean fields on ForeignKey model in form as checkboxes
I have a Django app that has the following models: class ProductNotification(models.Model): question_asked = models.BooleanField(default=False, help_text='Receive messages when a question is added') question_delete = models.BooleanField(default=False, help_text='Receive messages when question is deleted') # There are more boolean fields in here class Product(models.Model): name = models.CharField(max_length=255, unique=True) #... product_notification = models.ForeignKey(ProductNotification, on_delete=models.CASCADE, default=True) Each Product should have its own notification setting. My forms: class ProductNotificationForm(forms.ModelForm): question_added = forms.BooleanField(help_text='Receive messages when question is added.', required=False) question_delete = forms.BooleanField(help_text='Receive messages when question is deleted.', required=False) # same fields to come as in the model class Meta: model = ProductNotification fields = ['question_added', 'question_delete', ...] class ProductForm(forms.ModelForm): name = forms.CharField(max_length=50, required=True) # ... product_notification = forms.ModelChoiceField(queryset=ProductNotification.objects.all(), required=False) The problem is: The form adds the new "sub form" product notifications, but instead of a bunch if checkboxes for all the boolean fields, there is only one drop-down menu. I have tried ModelMultipleChoiceField too, without success. Can someone help me to get all the checkboxes displayed instead of one drop-down menu? Thanks a lot :) -
Django - how to order queryset for varying query?
I have this issue where I want to order my queryset according to a compute value based on a query in descending order. Query: ?fruit=Apple&?fruit=Pear In this case: Num. Apples + Num. Pears + (Num. Apples * Num. Pears) models.py class Costumer(BaseModel): name = models.CharField('name'), max_length=255, blank=True fruits = models.JsonField('fruit'), null=True, blank=True, default=dict) My Costumer.fruits looks something like this: fruits = {name: Apple, count: 10}, {name: Pear, count:4}, {name: Cherry, count: 1}, {name: Avocado, count: 2} views.py def get_queryset(self): fruits = dict(self.request.GET).get('fruit', []) queryset = Costumers.objects.all() if fruits: queryset = sorted(queryset, reverse = True, key=lambda costumer: self.calculate_order(costumer, fruits)) return queryset def calculate_order(self, costumer, fruits): value_list = [fruit['count'] for fruit in costumer.fruits if fruit['name'] in fruits] return sum(value_list) + (reduce((lambda x, y: x*y), value_list)) if value_list else 0 This seems to be ordering the data correctly from what I have tested so far, however doesn't seem like the best way to do it. Is there a better way using Django Queryset API for ordering this data? Since the way it's ordering now is a bit time consuming since I have to iterate on all the records on the database. -
django - on model save method, determine if field value is set explicitly, or a default value is being used

Prevent unauthorized user from accessing PDF file
I have a web application that allows users to download PDF files. The users are supposed to login or register (if not already registered) and after verification of credentials are allowed to view or download PDFs. Hence, only authorized users are able to access the PDFs. My question is, is there a way in which I can prevent the authorized users from sharing the PDFs with other unauthorized users? I have read about password encryption, digital certificates and Digital Rights Management. I also know that we can hide the toolbar in the browser using embed tag and prevent users from downloading the files. I have also read so many posts saying that preventing users from sharing the PDFs after it has been downloaded is simply not possible. But I just wanna know if it is possible to somehow embed a key with the PDF when it is being downloaded and invoke a script (preferably Python) to verify the user, when the user tries to open the PDF? Any help will be appreciated. Thanks. -

django-import-export how to skip import some rows based on current user login?
Actually started using django-import-export latest version. Wanted to know where exactly we can override to skip certain rows of the csv from being imported based on current user or the domains from a list of domains he can import data from the csv. How exactly to customize which of the methods to override and how? In my ModelResource, I have created the list of domains for the current user, and which method of the import-export do I check this and skip the rows from being imported? class MailboxResource(resources.ModelResource): mdomain_list = [] def before_import(self, *args, **kwargs): # make changes to csv super(MailboxResource, self).before_import(*args, **kwargs) muser_id = kwargs['user'].id muser = kwargs['user'] # import for all domains if muser.is_superuser: pass # import for domains belonging to the hierarchy elif muser is not None: exist = muser.groups.filter(name='customers').exists() self.mdomain_list.append(Domain.objects.filter( customer__in=Customer.objects.filter( email=muser))) Hence customer should be able to import data from the CSV only for domains that belong to him and skip all other rows from the CSV, which don't exist in the list. CSV: id,name,email,domain, 1,ABC pvt.ltd,abc@zinn.com,zinn.com, 2,XTD,xtd@ggg.com,ggg.co.in, 3,RTG,tiger@goa.com,goa.com If customer doesn't own ggg.com domain, only 1st and 3rd row should get added to the table via import.

Setup Unity mobile app login using Django OAuth2
I built the backend for a Django REST API on mydomain.com and have set up email authorisation and OAuth2 for google and facebook. I am a newbie to Unity (and Django before setting it up). I have a Unity mobile app for iOS and Android(that I obv did not develop myself) that I need to connect to Django for authentication to create users on the app. I've seen this post, but being completely new to JSON and Unity I wouldn't know how to begin implementing anything mentioned. Are there any tutorials with guided steps? Could you provide me with some basic information? The documentation dives straight into the deep end but is still not informative enough for me to use it for oauth. Closest youtube video I've found is for a fitbit and I don't know how to apply anything form there to my case. Literally any help would be greatly appreciated! (please :(( ) -
