How to convert an image to `InMemoryUploadedFile` when an URL of the image is received in DRF?
I have a response where the image URL is displayed, but when I try to send PUT/PATCH request then it raises an error as:- Here's the response:- { "floorplan": { "floor": 32, "image": "http://127.0.0.1:8000/media/floorplans/71d3e751-d38f-416f-ac22-d6ddb3fa3541.jpg" } } When A PUT request is sent:- { "floorplan": { "image": [ "The submitted data was not a file. Check the encoding type on the form." ] } } But when I try to send a request with an actual image uploaded, it works fine. This my serializer:- class NestedFloorplanSerializer(serializers.ModelSerializer): class Meta: model = FloorPlan fields = ( 'floor', 'image', ) I tried override the to_internal_value what is saw was in actual image is uploaded it is of the type:- <InMemoryUploadedFile: floor_1.jpg (image/jpeg)> and when the url is sent than the value I see in the to_internal_value is this http://127.0.0.1:8000/media/floorplans/71d3e751-d38f-416f-ac22-d6ddb3fa3541.jpg What I am trying to do is not do the validation when the the same url of the image is received in the to internal_value or if possible to convert the url to <InMemoryUploadedFile: floor_1.jpg (image/jpeg)> and then return it?? -
Django and postgres timezone converts to UTC
In my app users provide their timezone and saved. So I handle timezone conversion manually local_time = datetime.now(tz=ZoneInfo(self.time_zone)) Yet still when I save into postgres it is converted back to UTC 0. In the settings: # TIME_ZONE = 'UTC' #commented out USE_L10N = False USE_TZ = False That too did not work, so I made a middleware: # CUSTOM TIME ZONE HANDLER class TimezoneMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): time_zone = "US/Pacific" #will be changed to a fn call if time_zone: timezone.activate(pytz.timezone(time_zone)) else: timezone.deactivate() return self.get_response(request) In settings: MIDDLEWARE = [ ... 'time_log_app.utils.TimezoneMiddleware', ] That too is not working!! I'm pretty much out of hope here, what I'm doing wrong?? Or I should use raw sql for this? -

Django request.post only contains csrf field, however my form has two inputs: username and password, therefore i can not authenticate and login a user

How to deal with a serializer that needs context
I have a situation here where the serializer needs context, basically the request object. class ProductSerializer(ModelSerializer): distance_away = SerializerMethodField(read_only=True) class Meta: model = Product fields = [ 'pk', 'distance_away', ] def get_distance_away(self, obj): coordinates = self.context["coordinates"] distance_in_km = None if coordinates != 'null' and coordinates is not None: lat = float(tuple(coordinates.split(","))[0]) lng = float(tuple(coordinates.split(","))[1]) .... This means I have to pass a context whenever I use or call the serializer. That's fine for normal drf views. Now I am faced with a situation where I need to use the serializer in a ModelObserver class MarketplaceConsumer(GenericAsyncAPIConsumer): queryset = Product.objects.all() serializer_class = ProductSerializer permission_classes = [HasApiKey] @model_observer(Product) async def marketplace_activity(self, message: ProductSerializer, observer=None, **kwargs): await self.send_json(message) @marketplace_activity.serializer def marketplace_activity(self, instance: Product, action, **kwargs) -> ProductSerializer: '''This will return the product serializer''' return ProductSerializer(instance, context={'request': self.request}).data At this point I will get the following error which makes sense(self.request): 'ModelObserver' object has no attribute 'request' This ModelObserver is for handling channel websocket actions. Is there any way to solve this situation? -

Is there a way to set the id of an existing instance as the value of a nested serializer in DRF?
I'm developing a chat application. I have a serializer like this: class PersonalChatRoomSerializer(serializers.ModelSerializer): class Meta: model = PersonalChatRoom fields = '__all__' user_1 = UserSerializer(read_only=True) user_2 = UserSerializer() the user_1 field is auto-populated but the client should provide the user_2 field in order to create a personal chat room with another user. My problem is, when creating a new chat room, the serializer tries to create a new user object from the input data thus giving me validation errors. What I really want it to do is to accept a user id and set the value of user_2 field to an existing user instance that is currently available in the database and if the user is not found, simply return a validation error. (the exact behavior of PrimaryKeyRelatedField when creating a new object) I want my input data to look like this: { 'user_2': 1 // id of the user } And when I retrieve my PersonalChatRoom object, I want the serialized form of the user object for my user_2 field: { ..., 'user_2': { 'username': ..., 'the_rest_of_the_fields': ... } } How can I achieve this? views.py class GroupChatRoomViewSet(viewsets.ModelViewSet): permission_classes = [IsUserVerified, IsGroupOrIsAdminOrReadOnly] serializer_class = GroupChatRoomSerializer def get_queryset(self): return self.request.user.group_chat_rooms.all() def … -

Django Queryset Postgres

Python or Django library to convert html to an image or pdf
So I have two main issues: Finding a library that can convert an html file to an image and pdf (two separate libraries works too) Perform the conversion without exposing the html template in a URL What I've tried so far: I tried using imgkit but from my research, it's incompatible with my docker image: (python:3.7.11-alpine3.13). This was the error I was getting: OSError: wkhtmltoimage exited with non-zero code -11. error: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root I tried using django's render_to_string, to generate a string which can be saved as an html file containing the rendered context data. However, for iterations were not rendered in the string output of render_to_string Currently the only way for me to generate a valid html page with all the passed context data is by using render. However this implementation would not work because I can only access the html body via a URL, which in my case is a no-no for security resasons. Any help is greatly appreciated. Thanks! -

Why Django REST Framework (DRF) folder structure is different than Django Turorial?
If you follow the Django Tutorial you'll run theses commands: django-admin startproject mysite # Change into the outer mysite directory cd mysite python manage.py startapp polls and you'll get this folder structure mysite/ ├── manage.py │ ├── mysite/ │ ├── __init__.py │ ├── asgi.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py │ └── pools/ ├── migrations/ │ └── __init__.py ├── __init__.py ├── admin.py ├── apps.py ├── models.py ├── tests.py └── views.py But if you follow Django REST Framework and you'll run these commands: Note: I replaced the directory names to match, for better comparison # Create the project directory mkdir mysite cd mysite # Set up a new project with a single application django-admin startproject mysite . # Note the trailing '.' character cd mysite django-admin startapp polls cd .. and you'll get this folder structure mysite/ ├── manage.py │ └── mysite/ ├── __init__.py ├── asgi.py ├── settings.py ├── urls.py ├── wsgi.py │ └── polls/ ├── migrations/ │ └── __init__.py ├── __init__.py ├── admin.py ├── apps.py ├── models.py ├── tests.py └── views.py This is DFR's explanation: It may look unusual that the application has been created within the project directory.

Django view - objects are created but not present in a DB
I have a DRF view that imports Product objects in the database. The problem is that while the transaction is alive, everything looks correct. The objects created have their ids (so they have been stored in a DB).

django user update form not updating
I have a detailed user view that has a button for user update. The user update form is inside a modal, for that I am using a FormView ModelForm and a TbUser. I dont get how the form validation works but the fields are correct. When I update something for a user, I get an error, TbUser with username already exists, which means the code does not update the user but tries to add a new one. Also, I want to redirect to user-detail page after submit. How can I redirect to user-detail if the form is invalid sometimes and not displaying errors? Why the user is not updated?
