Heroku Django Gunicorn Error H18 (Request Interrupted) errors
I'm using Django with Gunicorn on heroku. And I make https requests via post to my backend sending some files (which don't need to be stored), locally everything works fine. But on heroku when I send small files (<13kbytes) it works, but for larger files I get Error H18 (Request Interrupted). I couldn't understand the reason for the error, if it's from heroku itself, if it's from the body of the request to be large or from gunicorn. What would be the best way to find out the possible cause of this, any ideas? -
How to get the value of manytomany field as a list in Django queryset
class Subject(models.Model): name = models.CharField(max_length=100, blank=True, null=False) category = models.CharField(choices=TYPE_CHOICES, null=True, max_length=50) setting = models.ManyToManyField(Contact) class Contact(models.Model): name = models.CharField(max_length=50, blank=True, null=True) email = models.EmailField(max_length=50, blank=True) id subject_id contact_id 1 66 13 2 66 28 3 71 13 4 71 28 5 98 13 6 98 28 7 98 37 8 20 13 Subject.objects.values('id', 'setting') -> [{'id': 66, 'setting': [13, 28]}, {'id': 71, 'setting': [13, 28]}, {'id': 98, 'setting': [13, 28, 37]}, {'id': 20, 'setting': [13]}] I was wondering how to get the value of manytomany field as a list in Django queryset.

how to filter a set of locations during a createview to select one or more locations
I'm stuck on how to approach the design of this problem - or even how to search for answers. I'm still a bit new with Django. The goal is to have a user select one or more locations (libraries in my problem) from a list of locations. I'd like the user to be able to type in an address and then have the list of locations filter based on distance between the locations. I envision the list of locations to be selection field. I'm assuming there will be an input field for the distance (canned choices or just a whole number) and a button to apply the filter. I know how to get the user's location (as a postal address) converted to lat/long using py-geocoder. I have the lat/long of each library. I know how to calculate the distance between two points (py-haverstine or maybe geometry-distance). Where this seems squirrely is the mechanics of filtering the list. How would I do the "filter" action (submit) versus the "save" action if I'm using a model based view? So far, when I hit the server, I've been processing the form as a submission, not a portion. Or would this be better done … -
Bootstrap-Select not updating on mobile
I am using Bootstrap-select for multi-select items with Django. It works fine on desktop, but when the native mobile drop-down is enabled, the selected values of the dropdown do not populate. HTML <!-- start product brand info --> <div class="row"> <div class="col-md-6 col-xs-*"> <div> <label for="id_brand-name" class="form-label">Products</label> </div> <select multiple class="form-control selectpicker mb-3" id="id_brand-name" name="brand-name" mobile="true" multiple required> {% for product in products %} <option value="{{product.id}}" id="optiion">{{ product.brand.name | title }} - {{product.name | title}}</option> {%endfor%} </select> <div class="invalid-feedback"> Select at least one product. </div> </div> </div> <!-- end product info --> <script> //Enble native drop down on mobile window.onload = function () { $('#id_brand-name').selectpicker({ container: 'body' }); if( /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent) ) { $('#id_brand-name').selectpicker('mobile') }}; </script> No matter how many items are selected, the selector always shows Nothing selected. When the data is posted, it is apart of the form though. -

Graphene mutation defined as null despiete returned value is NonNull
Im working with graphene to handle mutations on an application with django as backend. I wrote the following mutation: import graphene from django.db import transaction from graphql_jwt.decorators import login_required from app1.enums import SomeOptions from app1.models import SomeModel from app2.utils.some_api import SomeApi class SetOtherAppConfig(graphene.Mutation): url = graphene.NonNull(graphene.String) @login_required @transaction.atomic def mutate(self, info, *args, **kwargs): authorization_url = SomeApi().authorization_url user_id = int(info.context.session['_auth_user_id']) company_id = int(info.context.session['id_emp']) SomeModel.objects.get_or_create( company_id=company_id, code=SomeOptions.API.name, defaults={ 'name': SomeOptions.API.value, 'username': '', 'password': '', 'token': '', 'base_url': '', 'others': '', 'created_by_id': user_id, 'updated_by_id': user_id, }, ) return SetSomeConfig(url=authorization_url) The problem is that the mutation itself its being reported as null or string. The attribute url on the other hand can only be String as expected. How can I tell graphene that the mutation(or the class) can not be null? -
Seting Auth headers in Django tests
I am trying to write a test which goes through the signup/login workflow, and then attempts to change the status of a user, which requires them to be logged in. I verified that the first 2 POST requests work (the user is indeed created and then gets a valid auth token after logging in), however I cannot seem to pass in said token in the headers for the 3rd and final POST request. I also checked that the auth_headers variable is indeed set with the correct token, but I keep getting back a 401 status code.

Exceptions not bubbling up from LiveServerTestCase
We use LiveServerTestCase with Selenium for integration tests of a multi-page user flow. One of the flows is raising an exception at runtime, yet the test is passing. The exception is visible in the test logs, but does not cause the test to fail. Simplified example: class SmokeTest(LiveServerTestCase): def this_should_fail_but_passes(self): driver = webdriver.Chrome() driver.get('/home') # This test passes class HomeView(TemplateView): def get(self, request, *args, **kwargs): raise Exception("You would think the test would fail, but it doesn't.") Test passes, though exception is visible in logs... ... raise Exception("You would think the test would fail, but it doesn't.") Exception: You would think the test would fail, but it doesn't. . ---------------------------------------------------------------------- Ran 1 test in 2.248s OK The root cause seems to be that LiveServerTestCase launches a separate server instance and runtime errors that it experiences are logged, but do not bubble up as exceptions to the test client. -
Using multiprocessing with a dictionary that needs locked
I am trying to use Python's multiprocessing library to speed up some code I have. I have a dictionary whose values need to be updated based on the result of a loop. The current code looks like this: def get_topic_count(): topics_to_counts = {} for news in tqdm.tqdm(RawNews.objects.all().iterator()): for topic in Topic.objects.filter(is_active=True): if topic.name not in topics_to_counts.keys(): topics_to_counts[topic.name] = 0 if topic.name.lower() in news.content.lower(): topics_to_counts[topic.name] += 1 for key, value in topics_to_counts.items(): print(f"{key}: {value}") I believe the worker function should look like this: def get_topic_count_worker(news, topics_to_counts, lock): for topic in Topic.objects.filter(is_active=True): if topic.name not in topics_to_counts.keys(): lock.acquire() topics_to_counts[topic.name] = 0 lock.release() if topic.name.lower() in news.content.lower(): lock.acquire() topics_to_counts[topic.name] += 1 lock.release() However, I'm having some trouble writing the main function. Here's what I have so far but I don't know exactly how the arguments should be passed. def get_topic_count_master(): topics_to_counts = {} raw_news = RawNews.objects.all().iterator() lock = multiprocessing.Lock() with multiprocessing.Pool() as p: Any guidance here would be appreciated! -
Django ORM __in but instead of exact, contains case insensative?
I am currently trying to use the Django ORM to query the Recipe model's ingredients. class Recipe(models.Model): account = models.ForeignKey(CustomUser, on_delete=models.CASCADE, null=True, blank=True) name = models.TextField(null=True, blank=True) class RecipeIngredients(models.Model): recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE, null=True) ingredient = models.TextField(null=True, blank=True) What I have so far is ingredients = ["eggs", "bacon", "potato"] recipes = Recipe.objects.filter( recipeingredients__ingredient__in=ingredients ).alias( ningredient=Count('recipeingredients') ).filter( ningredient__gte=len(ingredients) ) From my understanding of this answer this will return all the items that contain only "eggs", "bacon", and "potato", but not say Eggs or Scrambled EGGS.

Django: Avoid users uploading files, use their local storage instead?
So I have a Python script that extracts data from .ifc (3D models for the AEC Industry) files to a .csv or .xlsx and I would like to make it available in a web app. The files can get pretty big (> 400MB) and users are rarely owners of these files, so they are probably not allowed to upload them. So I am looking for a way to avoid the file upload. Is something like that possible with a Django App? Or should I look into creating a desktop app with some other framework? -
