Why is my Django view not automatically downloading a file
My view transcribes a file and outputs the SRT transcript. Then it locates and is supposed to auto download theT transcript but nothing happens after transcription completes(the file was submitted on a previous page that uses the transcribeSubmit view. The view that handles and returns the file is the initiate_transcription view).

Django - inconsistent password hashing
Trying to build the user manager boilerplate of a Django (DRF) project. Facing some really weird issues when registering a user. First problem I encountered was passwords not being hashed. After some investigation I found out that the auth package has make_password function, which generates a hash from a given string. But then I noticed that I cannot authenticate these users. Tried to setup my own authentication logic using the check_password of the same package, when I realized, that the password hash stored in the database is completely different from the hash generated by make_password and passed to the set_password method of the user instance. I know I should provide some code, but the computer running the code doesn't have internet access (my wi-fi adapter has died) , but the structure of the user manager, view and serializer is almost same as here: https://github.com/dotja/authentication_app_react_django_rest/tree/main/backend I do use user.save() after setting up the password. I need to figure out either why the user's password not getting hashed without using the make_password function, or why the stored hash is different when using the make_password function. Thanks. -

How can I separate my labels in the x-axis into separate "categories" in my chart?
If my question didn't make sense then let me explain. Basically I am creating a web app for tracking expenses and I want to incorporate a chart to showcase the expenses in a graphical way. I have made for categories which take in separate data, but for some reason when I render the chart it shows all the categories combined as one. (Attachment is provided) Image of the Bar chart. For this reason only the line and bar chart show but the doughnut (which I want) and the pie charts don't work am guessing because of how the labels (categories) are combined into one. Here is the code for my js file: const renderChart = (data, labels) => { const ctx = document.getElementById('myChart').getContext('2d'); new Chart(ctx, { type: 'bar', data: { labels: labels, datasets: [{ label: 'Current Month Expenses', data: data, }] }, options: { borderWidth: 10, borderRadius: 2, hoverBorderWidth: 0, plugins: { legend: { display: false }, }, }, }); } const getChartData=() => { console.log("fetching") fetch('expense_category_summary') .then((res)=>res.json()) .then((results)=>{ console.log("results", results); const category_data = results.expense_category_data; const [labels, data] = [ Object.keys(category_data), Object.values(category_data), ]; renderChart([data], [labels]); }); }; document.onload = getChartData(); Please help, I am in a tight deadline.

Does user encoding of uploaded files matter and how to configure it?

Does their encoding matter or do they all end up being utf-8? I read this from the Django documentation. But I didn't quite understand how to configure file encoding. -

How to generate automatically links to picture with spec. size?
I'm a beginner in programming, I've done a small project in Django, but nothing special. I was given a recruitment task with Django RESTframework, but I don't really know how to approach it. I don't want a ready-made solution, but some guidance or advice on how to go about it. Possibly a shared coding :) Task: Using Django REST Framework, write an API that allows any user to upload an image in PNG or JPG format. You are allowed to use any libraries or base projects / cookie cutters you want (but using DRF is a hard requirement). Skip the registration part, assume users are created via the admin panel. Requirements: it should be possible to easily run the project. docker-compose is a plus ## This is no problem. This is main problem. users should be able to upload images via HTTP request users should be able to list their images there are three builtin account tiers: Basic, Premium and Enterprise: users that have "Basic" plan after uploading an image get: a link to a thumbnail that's 200px in height users that have "Premium" plan get: a link to a thumbnail that's 200px in height a link to a thumbnail … -

I have some problems with this error. Error began to appear after implementing the new functionality. Which involves checking whether the user's password has been marked for change.

Django channels: Execute consumer code from django drf view
I have django app with drf view and I want to call consumer by its name from the view. I'm using the following packages versions: Django==4.2.5 djangorestframework==3.14.0 channels==4.0.0 the following code prints nothing: settings.py: INSTALLED_APPS = [ 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ... 'rest_framework', 'drf_yasg', 'channels', ] CHANNEL_LAYERS = { "default": { "BACKEND": "channels.layers.InMemoryChannelLayer", }, } consumers.py: class TestConsumer(SyncConsumer): def test_consumer(self, message): print('start consumer') job = Job.objects.get(id=message.get('job')) job.status = Job.JobStatus.RUNNING job.save() print('Finish consumer') routing.py: ChannelNameRouter({ "test_consumer": TestConsumer, }) views.py: class TestAPIView(APIView): @transaction.atomic def post(self, request, *args, **kwargs): message = {"selected_indices": 'test', "session_search": ''search_test', "job": 1} channel_layer = get_channel_layer() async_to_sync(channel_layer.send)("test_consumer", message)
