Unresolved Reference in Pycharm Using Django
code I'm using Pycharm. I created a new app called pages that's part of this tutorial on Youtube. I created some functions in the pages/views.py. Then I went to urls.py to import the functions and add the URLs. But the IDE can't find pages. I tried restarting Pycharm/invalidating the caches, and that did not work. Please let me know if you have any ideas. -

How do I go about debugging 'OSError: Failed to write data' on my Flask server?
I'm running a Flask application (with some bits of Django ORM) on Elastic Beanstalk (code link: https://github.com/onnela-lab/beiwe-backend). However, I'm getting constant notifications from Elastic Beanstalk about 5xx failures (~5-25% failures). Looking at the logs (/var/logs/httpd/error_log), I see the following errors: Error 1: [Fri Nov 13 13:58:55.487007 2020] [:error] [pid 14630] [remote {load_balancer_ip_address:port1}] mod_wsgi (pid=14630): Exception occurred processing WSGI script '/opt/python/current/app/wsgi.py'.

Serve some static from Django and others from s3
I have a Django app on Heroku and recently moved all my static files to s3. This is working great, except a few static files used in a script that need to be served locally. I'm using the https://github.com/higuma/web-audio-recorder-js to let the visitor leave a voicemail. When the files are on S3, I get this error when leaving a voicemail: gum_error err.name: SecurityError; SecurityError: Failed to construct 'Worker': Script at '[my-s3-bucket]' cannot be accessed from origin '[my-domain]'. From this SO answer, it seems "Chrome doesn't let you load web workers when running scripts from a local file." So I think to solve this, I need to serve most of my static files on S3, but a few of them locally. I'm using django-storages and boto3 for static files, and it seems like it's all-or-nothing. -

Using GET parameters with Django and Ionic
I'm developing an application where I need to make HTTP requests, so I'm trying to use the GET method with parameters. My code in ionic is this: getZona(code: string) { return this.http.get( this.API_URL + "zonas", {codigo_acceso: code}, {} ); } My Django code is class ZonaView(viewsets.ModelViewSet): queryset = Zona.objects.all() serializer_class = ZonaSerializer So when I do a GET request, I get all records, even though if the parameter's value doesn't exists in the records. No matter what I write in the parameter, I get all records. I have tried with postman and I get the same behavior. Hope you can help me. -
Can I use an aggregation function on the result of a previous aggregation function in Django?
I've been receiving the following error on a query: Cannot compute Sum('failures'): 'failures' is an aggregate I have a model that represents a payment: class Payment(models.Model): created = models.DateTimeField(null=True) customer_name = models.CharField(max_length=50) status = models.CharField(max_length=20) # e.g. 'paid' or 'failed' When an user makes a purchase and tries to perform payment with her credit card, a Payment object is created. If the attempt fails, the status becomes 'failed'. An user may try several times, generating several Payment objects with the 'failed' status, and then give up, or maybe when she tried with a different card the nth payment was successful. I would like to perform an aggregated query where I can count both the total number of failed attempts and the "unique" fails, that is, counting a single fail for each customer that had a failed attempt. For example, suppose we had the following payment attempts Date/Time Customer Name Status 2020-11-10 8:00a.m Alice failed 2020-11-10 8:01a.m Alice failed 2020-11-10 8:02a.m Alice failed 2020-11-10 8:10a.m Bob failed 2020-11-10 8:11a.m Bob paid 2020-11-11 7:30a.m Charles failed 2020-11-11 7:31a.m Charles failed I would like to obtain the following result using a queryset: Date Total failures unique failures 2020-11-10 4 2 2020-11-11 2 1 … -
Django Rest Framework Serializer Method Calling
I'm new at Django Rest Framework and I wonder how methods create and update are called inside a ModelSerializer Class. What I understand is that create and update methods are automatically triggered when a POST or PUT request is sent. Is there a way to call a new function, like say_hello()? Here's an example. I want to call method say_hello() when I hit a PUT Request class UserSerializer(serializers.ModelSerializer): """Serializer for the users object""" class Meta: model = User fields = "__all__" def create(self, validated_data): """Create a new user with encrypted password and return it""" return get_user_model().objects.create_user(**validated_data) def update(self, instance, validated_data): """Update an user, setting the password and return it""" password = validated_data.pop('password', None) user = super().update(instance, validated_data) if password: user.set_password(password) user.save() return user def say_hello(self, validated_data): print(validated_data) return "Hello you" -

Django HttpResponseRedirect versus redirect
Given the following: def add(request): if request.method == "POST": task = request.POST.get('task') form = NewTaskForm(request.POST) if form.is_valid(): task = form.cleaned_data["task"] request.session['tasks'] += [task] # return HttpResponseRedirect(reverse("tasks:index")) return redirect('tasks:index') else: return render(request, "tasks/add.html",{ "form": form }) return render(request, "tasks/add.html",{ "form": NewTaskForm() }) what's the difference, why would you use one over the other, between: return HttpResponseRedirect(reverse("tasks:index")) and: return redirect('tasks:index') -

access to the coupon information in the webbook in stripe
I am using coupon in stripe checkout session. it works fine but I need to store the information once checkout successfully completed in my server. I am thinking of either of the following potential solutions: 1- pass the info to webhook: @csrf_exempt def stripe_webhook(request, **myextrainfo**): 2- somehow find the used coupon info in the webhook event = stripe.Webhook.construct_event( payload, sig_header, endpoint_secret ) I don't know if the first is doable and about the second, I can almost retrieve all the information like customer, product, total, subtotal but I cannot find coupon info. here is information that I can retrieve: session = event['data']['object'] line_items = stripe.checkout.Session.list_line_items(session['id'], limit=1) print(line_items) print(line_items["data"][0]["price"]["id"]) print(line_items["data"][0]["price"]["product"]) print(line_items["data"][0]["price"]["recurring"]["interval"]) print(line_items["data"][0]["price"]["recurring"]["interval_count"]) I appreciate if someone can help me. -
Heroku + Django : Restarting a dyno every 15 min
I have a Django website hosted on Heroku. I need to restart 1 dyno "clock" every 15 minutes. Through Heroku CLI, this can be done through the command line: heroku dyno:restart clock.1 But I can't seem to automate it from within the Django app. I don't know if a Django scheduled job/management command can execute a Heroku CLI command. Currently my back-up solution is to have : one .bat to 1) Activate my venv 2) execute heroku dyno:restart clock.1 one Windows Task Scheduler to launch my .bat every 15 min. (Yes... my laptop has been on for months now) What I want is a cronjob inside my Django app, which would restart this dyno every 10 min. Or anything like that ? -

How can I find the current users primary key to check if it matches a notes pk?

And I'm getting 500 Internal server error over the line AuthToken.objects.create(user)[1] and my import for the AuthToken is from knox.models import AuthToken And my error logs are: Traceback (most recent call last): File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\db\backends\utils.py", line 84, in _execute return self.cursor.execute(sql, params) psycopg2.errors.UndefinedTable: relation "knox_authtoken" does not exist LINE 1: INSERT INTO "knox_authtoken" ("digest", "token_key", "salt",... ^ The above exception was the direct cause of the following exception: Traceback (most recent call last): File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\core\handlers\base.py", line 179, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\views\decorators\csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\views\generic\base.py", line 70, in view return self.dispatch(request, *args, **kwargs) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\rest_framework\views.py", line 509, in dispatch response = self.handle_exception(exc) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\rest_framework\views.py", line 469, in handle_exception self.raise_uncaught_exception(exc) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\rest_framework\views.py", line 480, in raise_uncaught_exception raise exc File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\rest_framework\views.py", line 506, in dispatch response = handler(request, *args, **kwargs) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\auths\views.py", line 43, in post token = AuthToken.objects.create(user)[1] File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\knox\models.py", line 20, in create instance = super(AuthTokenManager, self).create( File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\db\models\manager.py", line 85, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) File "C:\Users\meesn\PycharmProjects\marketkonnectapi\venv\lib\site-packages\django\db\models\query.py", line 447, in create obj.save(force_insert=True, … -
How to step wise post data to an object using the Django-Rest Framework?
I want to post an object with Django-Rest Framework to my backend. The object contains multiple nested objects, and the user inserts this information setp-wise via a React JS frontend. class Story (models.Model): title = models.CharField(max_length=100,blank=False) content = models.TextField(blank=False) date_posted = models.DateTimeField(default=timezone.now) place = models.ForeignKey(Place, on_delete=models.PROTECT, null=True) author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True) images = models.FileField(upload_to='audio_stories/',validators=[validate_file_extension_image], blank=False) audio = models.FileField(upload_to='audio_stories/',validators=[validate_file_extension_audio], blank=False) I now wonder how it is possible to send the data to the server step by step. Is there a way to initiate a story object at the very beginning of the creation process to generate its primary key and then add the other data to this key step by step, e.g. images and audio? I've already searched for the right term in the Django documentation, but I'm having difficulties to approach this topic. I am happy for any clarification.
