In drf-spectacular swagger, post method have 3 content types as below application/json application/x-www-form-urlencoded multipart/form-data Is there anyway to make "application/x-www-form-urlencoded" as default content type for my post method. @extend_schema( description='API authentication using login & password', # OpenApiRequestBody('content': "application/x-www-form-urlencoded") ) In extend_schema function, tried to add content type as form-urlencoded. but no luck.

How to fetch data by foreign key in Django serializers?
I'm stuck on fetching data with a related foreign key. I am doing some kind of validation in which the create method would be allowed depending on the requesterid to be POSTed. This is my userTable model: class userTable(models.Model): userid = models.UUIDField(primary_key=True, default = uuid.uuid4, editable=False) username = models.CharField(max_length=50, null=False, unique=True) userroleid = models.ForeignKey(roleTable, on_delete=models.CASCADE) def __str__(self): return self.username Another model is the requestTable class requestTable(models.Model): rid = models.AutoField(primary_key=True) requesterid = models.ForeignKey(userTable, on_delete=models.CASCADE) (...) This is my serializer: class RequestCreateSerializer(serializers.ModelSerializer): parts=PartSerializer(many=True) class Meta: model = requestTable fields = ['rid','requesterid', (...)] def create(self, instance, validated_data): if instance.requesterid.userroleid == 3: #how can i fetch my `requesterid` data? parts_data = validated_data.pop('parts') request = requestTable.objects.create(**validated_data) for part_data in parts_data: partsTable.objects.create(request=request, **part_data) return request raise ValidationError("Sorry! Your role has no permission to create a request.") Also, I'm quite confused if I should do validation in serializers, or views. If I do it in views, it just throws the ValidationError, and it doesn't seem to enter the if condition. For reference, here's my views: class RequestListCreateView(ListCreateAPIView): queryset = requestTable.objects.all() serializer_class = RequestCreateSerializer def create(self, request, *args, **kwargs): if request.data.get('requesterid__userroleid') == '3': write_serializer = RequestCreateSerializer(data=request.data) write_serializer.is_valid(raise_exception=True) self.perform_create(write_serializer) headers = self.get_success_headers(write_serializer.data) return Response({"Request ID": write_serializer.instance.requestid, "Parts ID": [p.partsid … -
400 Bad Request error in response to PUT/POST request
My project is to create a twitter style web application. I'm trying to implement a feature whereby a user can edit the content of their posts. Whenever I click 'save' to edit the post I receive: This is the context of my fetch request: const edit_div = document.createElement('div'); edit_div.innerHTML = `<p id="edit" style="color: blue;">Edit</p>`; edit_div.querySelector('#edit').addEventListener('click', () => { post_div.querySelector('#content').innerHTML = ` <textarea id="edited">${post.content}</textarea> `; edit_div.innerHTML = `<button id="change_post">Create change</button>`; edit_div.querySelector('#change_post').addEventListener('click', () => { const new_content = post_div.querySelector('#edited').value; fetch(`/posts/${post.id}`, { method: 'PUT', body: JSON.stringify({ content: new_content }) }) This is my URL in urls.py file path("posts/<int:post_id>", views.post, name="edit_post"), This is what I've created in views.py @csrf_exempt @login_required def post(request, post_id): edited_post = Post.objects.get(id=post_id) return JsonResponse(edited_post) Using POST instead of PUT gets me the same result.

How to generate a (html) file from a view in Django
I have a Django-driven website with several applications which are dynamically updated, but not too often, like "About", "Our services", etc. They have a two-level structure of pages, which I want to reflect in the top pop-up menu (see the picture). I could make it as a custom simple_tag called each time from the base.html template. It would generate a menu each time a user opens or reloads a page, but think it is very costly since the app structure is changed seldom (say, once a year). Instead, I want to like to generate an HTML code of the menu each time the app structure is updated. It will be stored as a statical HTML file, so my base.html will include the menu as a ready piece of code. Are there recipes on how to generate an HTML file from the views (CreateView, UpdateView, DeleteView)? -

Django migration failed due to lack of memory. Query can't be killed
I deleted a column in a large table from a django migration. Due to lack of memory, the migration failed and the database restarted. (Managed database digital ocean mysql v8) After the database restarts, the drop column query runs again, and every time I kill the query through tableplus (mysql), the query restarts again. Meaning that my database runs out of memory every 15 minutes (I was in the process of deleting unnecessary data to free up memory) and restarts again. How can I kill this query for good? -
Django rest framework : custom object permissions doesn't work
My problem is very simple : I'm trying to create some custom permissions for my django rest API. This is my code (permission.py) : class UserPermissions(permissions.BasePermission): def has_object_permission(self, request, view, obj): return obj == request.user I just want that the users can only get, delete and update their own account. The problem is that I think my code is not read by Django. I have try to always return false (without any condition) and it does nothing. I have also try to print some debug message at the beginning of the file and it's does nothing. (My file permissions.py is at the root of my application) -

Remove field from drf-api-tracking for Django Rest Framework
I'm using drf-api-tracking to track requests to an api build with Django Rest Framework. With time, the size of the resulting table is growing too big, and I don't need the information stored in the column that takes up the most space ("response", which contains the full JSON response data). Is there a way to systematically avoid storing this information? In the documentation I found instructions on how to avoid logging at all in certain cases, but not on how to skip individual columns. -

How to correctly perform async django task execution
I am trying to make it so that a User is able to click Download on a web page to download about 30 reports from a third party API. Obviously, this takes time. So I am planning on implementing a WebSocket-based webpage that displays the status of that particular download (even if they reload the page) using Celery, Redis and Django Channels and Postgres. If a user wishes to download multiple reports at once, each download will be placed in a Queue. I know how to create tasks and use Django Channels, I’m just wondering if there is a standard way to manage task status in the database, so no matter what happens - the download on the front-end isn’t always saying ‘processing’ forever if it has failed for example. Is there a correct way to store the status of the task in the database? What if the download (task) fails during execution, how does it get stored? Any help would be appreciated. I have created the front-end thus far and prepared for websocket execution. -
404 Error while serving files with django
I want to access logs easily on my app so I created a page for that, I click on a button and it download the log. But I get a 404 error when I try to do that, I've set static files and media files here are my settings STATIC_URL = 'static/' STATICFILES_DIRS = [ "frontend/static", ] MEDIA_URL = 'media/' MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'media') LOG_URL = 'static/logs/' LOG_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'static/logs') and here are my urls urlpatterns += static(settings.LOG_URL, document_root = settings.LOG_ROOT) urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT) It works when I access /media/path/to/media.file, but not for /static/logs/path/to/logs.txt, it's the same configuration for both urls so I know I miss a point, but how could I fix it? Is it because I used static and not media? Thx a lot -

Django Override the Default success_url in contrib.auth.views
I made an app with app_name = 'accounts' in urls.py of the django and created signup/login pages there using the built-in signup function.

I'm a python beginner and struggling with this problem already for a month.. how can I achieve this?

I even tried putting try/except method with except 'NoReverseMatch:' but the function itself did not exist. -
