"error": "Could not connect to websocket endpoint wss://api-such.andsuch.xyz/graphql/. Please check if the endpoint url is correct."
I recently deployed a project I'm working on to production. I use this great library and I have GraphQL Playground set up via django-graphql-playground. Everything works fine locally - there are no issues whatsoever. However, when I deployed I get the error below when I hit the Play button in Playground: { "error": "Could not connect to websocket endpoint wss://api-such.andsuch.xyz/graphql/. Please check if the endpoint url is correct." } I use Gunicorn with a Uvicorn worker class in production. I even used the Gunicorn command locally to see if the issue could be from there but it works. One thing to note is that the application is dockerized. Could it be from there? I don't think so because it works locally. Here's what my docker-compose file looks like: version: '3.7' services: nginx: container_name: nginx image: nginx restart: always depends_on: - web volumes: - ./web/dev.nginx.template:/etc/nginx/conf.d/dev.nginx.template - ./static:/static - ./media:/media ports: - "8080:80" networks: - SOME_NETWORK command: /bin/bash -c "envsubst \"`env | awk -F = '{printf \" $$%s\", $$1}'`\" < /etc/nginx/conf.d/dev.nginx.template > /etc/nginx/conf.d/default.conf && exec nginx -g 'daemon off;'" web: container_name: web restart: always build: ./web networks: - SOME_NETWORK depends_on: - postgres - redis volumes: - ./web:/usr/src/app/ environment: - REDIS_HOST=redis - REDIS_PORT=6379 … -
Django ModelFormset: Using two separate models, one to render survey question, one to save responses
I am new to Django, and am stuck. I am creating a survey using two models: one to describe the survey question, and one to store the response (either a choice of answers defined by QUESTION_ANSWER_CHOICES, or a text field): class PassengerRequirement (models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) ... question_number = models.CharField(max_length=12, default=0, unique=False) question_text = models.TextField(max_length=256, null=True, blank=True, help_text="Put the question in this field.") ... class PassengerRequirementMeasurement (models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) survey_question = models.ForeignKey('PassengerRequirement', related_name='passenger_requirement_answer', on_delete=models.CASCADE) survey_instance = models.ForeignKey('SurveyInstance', related_name='passenger_requirement_measurements', on_delete=models.CASCADE, null=True) answer_choice = models.CharField(max_length=1, choices=QUESTION_ANSWER_CHOICES, default=YES) answer_text = models.TextField(max_length=256, null=True, blank=True, help_text="Add Details") Then using the modelformset_factory a formset in forms.py: prFormSet = modelformset_factory(PassengerRequirementMeasurement, fields=('answer_choice', 'answer_text'), extra=0 ) And my view: def passenger_requirements_pretravel(request): surveyquestions = PassengerRequirement.objects.filter(...) if request.method == 'POST': formset = prFormSet(queryset=PassengerRequirement.objects.filter(...), data=request.POST) if formset.is_valid(): print('no problem') else: print(formset.errors) ... else: formset = prFormSet(queryset=PassengerRequirement.objects.filter(...) return render(request, 'surveys/passenger_requirements_pretravel.html', {'formset': formset, 'surveyquestions': surveyquestions}) The issue is, I can't get past the is_valid() method; it always returns a list of: [{'id': ['This field is required.']}, {'answer_choice': ['This field is required.'],... for each question in the list. I've tried an approach modelled after this question but still get something similar: <ul class="errorlist"><li>answer_choice<ul class="errorlist"><li>This field is required.</li></ul></li></ul> Any suggestions?

gte is only showing objects for this month (equal to) and not greater than
I'm going to try to show you this without exposing customer data Query: Booking.objects.filter(startTime__year__gte=2020, startTime__month__gte=7,startTime__day__gte=27, depositPaid=True).order_by('startTime') This should show all bookings from July 27, inclusive, onward into the future with no bounds. However, the bounds is on the 8th month. None of the bookings for August are showing. If I run: Booking.objects.filter(startTime__year__gte=2020, startTime__month__gte=8,startTime__day__gte=1, depositPaid=True).order_by('startTime') Then I do get all the bookings in August. I don't understand why startTime__month__gte=7 doesn't show August. -
Django Mutllevel foreign keys Admin Editor
I have Country/State/City models. class Country(models.Model): name = models.CharField(max_length=127) class State(models.Model): country = models.ForeignKey(Country, on_delete=models.CASCADE) name = models.CharField(max_length=127) class City(models.Model): state = models.ForeignKey(State, on_delete=models.CASCADE) country = models.ForeignKey(Country, on_delete=models.CASCADE) name = models.CharField(max_length=127) All of them are registered. I want to add/edit/delete all of them in Admin Editor. Now, when I want to add a new City, I naturally would have to select the State and Country from the drop-down list. But in the current condition, if I select a particular Country, all the States are showing up including those that do not belong to the selected Country. I want the available options in the drop-down lists to abide by the selections. How can I achieve that for the Admin in the simplest way? Thanks -
AttributeError: module 'hello.views' has no attribute 'index' in Django while trying to create a helloWorld page
so I have been trying to follow the CS Harvard course thing but I'm stuck on lesson three lmao. they are using django to make a website I think? and I've run into this problem because I'm copying exactly what the instructor is doing but i still cant make my other part show up. What its supposed to do is have the basic website IP thing and then if i add /hello it should say hello world but it doesnt. The only files ive changed are these urls.py in lecture3 from django.contrib import admin from django.urls import include, path #added import include and path hello line urlpatterns = [ path('hello/', include("hello.urls")), path('admin/', admin.site.urls), ] urls.py in hello from django.urls import path from hello import views urlpatterns = [ path("", views.index, name="index") ] views.py in hello from django.http import HttpResponse from django.shortcuts import render Create your views here. def index(request): return HttpResponse("Hello, world!") and then in settings.py, the only line i added was 'hello', inside of the installed apps part. and the error message i keep on getting is File "/Users/matc/Dev/cfehome/lecture3/hello/urls.py", line 7, in path("", views.index, name="index") AttributeError: module 'hello.views' has no attribute 'index' any help would be greatly recommended! -

Django modelformset is_valid method retrieves entire model from database
I have a modelformset when is_valid method is called the entire model objects of the underlying form is retrieved from the database which is not efficient if the database table contains hundred of thousands records, I believe Django was not designed with this deficiency and there must be something wrong with my code, When is_valid is called these queries are sent to the database, the first query has no WHERE clause which means it will retrieve the entire table!: [{'sql': 'SELECT @@SQL_AUTO_IS_NULL', 'time': '0.000'}, {'sql': 'SET SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED', 'time': '0.000'}, **{'sql': 'SELECT `npr`.`rid`, `npr`.`PID`, `npr`.`rel`, `npr`.`CID` FROM `npr` ORDER BY `npr`.`rid` ASC', 'time': '0.037'}** {'sql': 'SELECT `person_details`.`ID`, `person_details`.`firstName` FROM `person_details` WHERE `person_details`.`ID` = 198 LIMIT 21', 'time': '0.001'}, {'sql': 'SELECT `person_details`.`ID`, `person_details`.`firstName` FROM `person_details` WHERE `person_details`.`ID` = 1243 LIMIT 21', 'time': '0.000'}, {'sql': 'SELECT `npr`.`rid`, `npr`.`PID`, `npr`.`rel`, `npr`.`CID` FROM `npr` WHERE `npr`.`rid` = 1377 LIMIT 21', 'time': '0.000'}, {'sql': 'SELECT (1) AS `a` FROM `person_details` WHERE `person_details`.`ID` = 198 LIMIT 1', 'time': '0.000'}, {'sql': 'SELECT (1) AS `a` FROM `person_details` WHERE `person_details`.`ID` = 1243 LIMIT 1', 'time': '0.000'}, {'sql': 'SELECT (1) AS `a` FROM `npr` WHERE (`npr`.`CID` = 1243 AND `npr`.`PID` = 198 AND NOT (`npr`.`rid` … -

It is ok to use multiple one-to-one relationships for one table?
I want to add a translation feature for a Django application. The core app has some standard texts in different tables as CharFields. I want to build this feature in another app, so I can copy it to similar projects. I have the following idea: Core app: Business Table 1: name (OneToOne: CoreText) Business Table 2: name (OneToOne: CoreText) CoreText Table: key (simple identifier for humans) value (default text) Translation's app Translations Table: core_text (FK: CoreText) language value The CoreText table would work as an interface between the core and translation apps. It's good to mention that BusinessTable 1 and 2 don't grow over time, but the texts related used to change. The relationship between BTs and Texts would be done one time during configuration. I've been reading some 'not good' opinions about one-to-one relationships so I would like to know if this approach is ok. -

class Category(models.Model): name = models.CharField(max_length=200) parent = models.ForeignKey("self", blank=True, null=True, related_name='children', on_delete=models.CASCADE) class Meta: unique_together = [ ('parent', 'name'), ] In this model I am able to create multiple objects with Category.objects.create(name="cat1", parent=None) # Category.objects.create(name="cat1", parent=None) # unique_together constraint should not allow this object's reaction, but it is; behavior is the same even when the parent is not None. Django version I am using is 3.0.8
