Kubernetes liveness probe fails when the logs show a 200 response
I am using https://pypi.org/project/django-health-check/ for my health checks in a Django app run through kubernetes_wsgi with the following YAML: livenessProbe: httpGet: path: /ht/ port: 8020 httpHeaders: - name: Host value: pdt-staging.nagyv.com initialDelaySeconds: 5 periodSeconds: 10 successThreshold: 1 failureThreshold: 10 readinessProbe: httpGet: path: /ht/ port: 8020 httpHeaders: - name: Host value: pdt-staging.nagyv.com initialDelaySeconds: 20 timeoutSeconds: 5 The pod logs claim that the probe was successful: INFO:twisted:"-" - - [22/Jul/2022:22:11:07 +0000] "GET /ht/ HTTP/1.1" 200 1411 "-" "kube-probe/1.22" At the same time, the pod events deny this: Liveness probe failed: Get "http://10.2.1.43:8020/ht/": context deadline exceeded (Client.Timeout exceeded while awaiting headers) ... and after a while, the pod regularly restarts. The pod seems to be fully functional. I can reach the /ht/ endpoint as well. Everything seems to work, except for the liveness probes. I read about slow responses causing the issue, but this is pretty fast. Any idea what the issue might be? -

Django error handling - "exception" is not accessed - Pylance
I have the following views.py to handle 400, 403 and 404 error requests def handler400(request, exception): return render(request, "400.html", status=400) def handler403(request, exception): return render(request, "403.html", status=403) def handler404(request, exception): return render(request, "404.html", status=404) In my Project's urls.py file I have: handler400 = 'tasks.views.handler400' handler403 = 'tasks.views.handler403' handler404 = 'tasks.views.handler404' handler500 = 'tasks.views.handler500' The app that the views are in is named tasks. DEBUG = False is in my settings.py file. When I purposefully create an error, the error handler does not work. As mentioned, in my views.py file the "exception is not accessed - Pylance." Any help would be greatly appreciated. -

row num in Django REST Framework
Is there any way to assign increasing integers to queryset objects ? qs = self.get_queryser() I know that I can use enumerate function like this: for i, obj in enumerate(qs): print(i, obj) but this is not what I need , I want to have something like rownum pseudocolumn for each object of qs, so when I pass obj to any other function, rownum will be passed along with it. for obj in qs: some_func(obj) /* here obj should include rownum */ Thank you in advance -
Calling a django view inside of a playwright scraper function
a. I have a scraper function shown below where I need a captcha input in order to move ahead with the scraping. b. I need the flow to happen as follows: I click a button inside a Django view to start the scraping on a web page. The scraper starts running and reaches the page on the MCA website with the captcha. Playwright captures a screenshot of the captcha as an image and sends the same to a Django view to be rendered as an image on a page while Playwright waits for the input from the user in the Django view. A Django view loads the captcha on a page with a form seeking user input for the captcha. Once the user enters the captcha in the form inside of a Django view and submits it, the user input gets submitted to Playwright which then enters the captcha on the page and continues scraping the MCA website. The data collected by Playwright is returned as a dictionary and saved in a Django model. My question is how do I implement 3. and 4. above. The scraping code is below: """Get profile data from mca.gov.in for a given CIN or … -
Only displaying certain options in django form dropdown
Gday, I am creating a site to manage data for software with django. Users on the site are linked to divisions (regions) in a divisions model through a many to many field. The actual data is all linked to profiles, which are owned by divisions. Division users can edit profiles owned by the division, but not others. My issue is with forms to create profiles. Attached is an image of the form. The division field shows all divisions registered on the site, but I only want it to show ones that the logged in user is a member of. For example, this user is only a member of 'VATPAC' so it should only show that as an option to select. Attached is all the relevant code. Forms.py class ProfileForm(ModelForm): class Meta: model = models.Profile fields = ('division', 'name') widgets = { 'division': forms.Select(attrs={'class':'form-control'}), 'name': forms.TextInput(attrs={'class':'form-control'}) } views.py def AddProfile(request): submitted = False if request.method == "POST": form = forms.ProfileForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect('profile?submitted=true') else: form = forms.ProfileForm if 'submitted' in request.GET: submitted = True return render(request,'profiles/create/create_profile.html', {'form': form, 'submitted': submitted}) models.py class Profile(models.Model): division = models.ForeignKey(Division, on_delete=models.CASCADE) name = models.CharField(max_length=255) def __str__(self): return self.name models.py (foreignkey for division) class … -

How do I dynamically change the value of text in html whenever a python variable is changed using ajax?
I'm using ajax, python, Django, HTML, and javascript for my project. I'd like to know if there is a in my HTML file like, <p class='text_box', id='tbox'> {{ text_variable_from_python }} </p> <input class='input_box', id='ibox', type='text'> Then I'd input some text into the input box, make a simple ajax request with the "text" variable and get an output from the server, which I would update on the views.py as, def main(request): if request.method == 'POST': new_text = request.POST['text'] context = {'text_variable_from_python': new_text} else: context = {'text_variable_from_python': 'You can change me!'} print(context) return render(request, 'Main.html', context=context) My question is, how do I send the data dynamically from the server to appear on client's webpage using ajax and python in between the two? Using my method, I can only see "You can change me!" on the webpage or nothing at all. No matter how many differing prompts I give, further changes do not show on the webpage. -

Django: ModuleNotFoundError: No module named 'name_project' after doing refactor
I have initialized a Django project with the help of Pycharm with "name_project" and for several reasons, I decided to refactor the name of the project and directory to "name".

I have tried class LocationSerializer(serializers.ModelSerializer): country = serializers.SlugRelatedField(slug_field="isoCode", queryset=Country.objects.all()) state = serializers.SlugRelatedField(slug_field="isoCode", queryset=State.objects.filter(country__isoCode=country)) city = serializers.SlugRelatedField(slug_field="name", queryset=City.objects.all()) class Meta: model = Location fields = ["user", "country", "state", "city"] But it does not work, it gives the error {"state":["Object with isoCode=BC does not exist."],... How does one create a dynamic linked serializer? Or how does one work around this? -

Django Queryset Design: Filtering out soft-deleted users?
I have a soft-delete user model in Django, where we set is_active to False. But one problem I'm running into is needing to filter out is_active users on every type of content: Item.objects.filter(user__is_active=False, ...) Comment.objects.filter(user__is_active=False, ...) User.objects.filter(is_active=False, ...) And so-on. Is there some type of Django / Pythonic design pattern I can use here to avoid needing to manually filter out all users every time I query something made by a user, or a current list of users? -
