How to avoid client caches (Chrome) on django react app?
I have a django-react app that is serving out of Heroku. I use webpack to build static files, which I serve out of a Django app called frontend. Django static files serving adds a hash to the webpack generated files for cache breaking on new releases. To illustrate, here is the index.html that is served for my site: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <link rel="icon" href="/static/favicon.e62ca627caf.ico" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta name="theme-color" content="#000000" /> <link rel="stylesheet" type="text/css" href="/static/frontend/css/index.e861872e9ba7b.css"/> <link rel="manifest" href="/static/manifest.a22d2aecab21fe.json" /> </head> <body> <div id="root"></div> <script src="/static/frontend/js/index.a39c981a0accf.js"></script> </body> </html> Cache-Control for index.html is set to max-age=0. I thought this setup would be good enough for breaking client caches when I release a new frontend version of my site (since index.*.js would have a new hash). However, I observed that some of my clients had stale versions up to two weeks ago even with this setup (using Chrome on Windows). How is this possible? Am I missing something to break client caches for new frontend releases? -

Why is my Django view not automatically downloading a file

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.

Django order by pviot table column
I want to order tasks within a bucket based on the 'order' column in the 'bucket_task' table. Tasks and buckets have a many-to-many relationship. How can I achieve this? My models: class Bucket(AbstractModel): user = models.ForeignKey(User, related_name='buckets', on_delete=models.deletion.DO_NOTHING) unique_id = models.CharField(max_length=255, default=uuid.uuid4, unique=True) title = models.CharField(max_length=191, blank=True) order = models.IntegerField(default=1) class Task(AbstractModel): user = models.ForeignKey(User, related_name='tasks', on_delete=models.deletion.DO_NOTHING) unique_id = models.CharField(max_length=255, default=uuid.uuid4, unique=True) title = models.CharField(max_length=191, blank=True) class BucketTask(AbstractModel): bucket = models.ForeignKey(Bucket, on_delete=models.deletion.CASCADE) task = models.ForeignKey(Task, on_delete=models.deletion.CASCADE) order = models.IntegerField(default=1) My view: class BucketsView(generics.ListCreateAPIView): permission_classes = [IsAuthenticated] serializer_class = BucketSerializer model = Bucket def get_queryset(self): queryset = self.model.objects.filter( user=self.request.user, deleted_on__isnull=True ).prefetch_related( 'tasks' ).select_related('user').order_by('order') return queryset My Serializer: class BucketSerializer(ModelSerializer): tasks = TaskSerializer(many=True, read_only=True) class Meta: model = Bucket fields = "__all__" read_only_fields = ['unique_id', 'tasks'] extra_kwargs = {"user": {"required": False}} -

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 … -
aws elastic beanstalk deployment error: 502 gateway error
I've been trying to deploy a django application using Django 4.2.6 on the latest platform that AWS EB has to provide: Python 3.9 running on 64bit Amazon Linux 2023/4.0.4 After any try or redeploy I've been getting a 502 Bad gateway issue and I would appreciate some help in debugging this. On the web.stdout.log file I see this log line: web[2059]: ModuleNotFoundError: No module named 'ebdjango.wsgi' which is confusing because I don't see anything I've done different than what's been suggested across the internet via blogposts and so on. All my sourcecode is available here: https://github.com/kolharsam/assignment-practical-swe These are the links I've been looking into: https://medium.com/@justaboutcloud/how-to-deploy-a-django3-application-on-elastic-beanstalk-python3-7-and-amazon-linux-2-bd9b8447b55 https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html https://testdriven.io/blog/django-elastic-beanstalk/
