Django loop through list in two parts
I do not understand how I can loop through a list in two goes. For example, display items 0-3, then 4-7. In particular, the list "arr" is passed through the view, then I'm in the template trying to display the list. I've trying a while loop, or slice etc, but just keep on getting errors. arr contains 3 string values per iteration from the views arr.append([title, link, img_url]) <div id="newsgrid"> {% for article in arr %} <div class="card"> <img src="{{ article.0 }}" alt="news image"> <small><a href="{{ article.1 }}">Read more</a></small> </div> {% endfor %} -
Why is a POST request successfully sent from the local server, but not from the production server?
I'm doing a project in django and I've uploaded it to a server with gunicorn+nginx. Everything works fine except my POST request. I have a form on the index page with this code: <form method="post" > {% csrf_token %} <input type="hidden" name="subject" value="Consultation form"> <div class="row row-cols-lg-3 row-cols-1 gy-lg-20 gy-10"> <div class="col"> <input class="form-control form-control-xxl text-center w-100" placeholder="Your name" type="text" name="name"/> </div> <div class="col"> <input class="form-control form-control-xxl text-center" placeholder="Your phone" type="tel" required name="phone"/> </div> <div class="col"> <button class="btn btn-primary btn-xxl w-100" type="submit">Get consultation </button> </div> </div> </form> I also have a handler in the views.py file: def handle_post_request(request): if request.method == 'POST': subject = request.POST.get('subject') phone = request.POST.get('phone') name = get_POST_parameter('name', request) if phone != '' and phone != None and subject != '' and subject != None: # Send data via HTTP POST request url = 'https://svarnik.ru/bx24/' headers = {'User-Agent': 'Reforgebot/1.0'} data = { 'ikey': 'someSecretKey', 'domain': 'example.com', 'roistat': 'nocookie', 'subject': subject, 'name': name, 'phone': phone, } try: response = requests.post(url, headers=headers, data=data) except Exception as e: pass return redirect('index') def index(request): if request.method == 'POST': handle_post_request(request) ...

Django redirect with message after XMLHttpRequest
I have a template that send a JSON to my backend with a POST XMLHttpRequest with var xmlhttp = new XMLHttpRequest(); // new HttpRequest instance var theUrl = "newSeq"; xmlhttp.open("POST", theUrl); xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8"); xmlhttp.setRequestHeader("X-CSRFToken", csrftoken); xmlhttp.send(JSON.stringify(my_json)); The Django backend manage the request with def newSeq(request): if request.method == "POST": print(request.body) messages.success(request, "Ricevuto") return redirect("newSeq") return render( request, 'dashboard/newSeq.html', { } ) My issue is that the redirect doesn't work and on the frontend I have the error the cookies "messages" has been rejected because it is already expired Is there a way to delete the specific cookies and make the page redirect with the correct message? -
Setting ManyToManyField intermediate field in form in Django
Suppose I have such model: class Person(models.Model): name = models.CharField(max_length=128) class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Person, through="Membership") class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) created_by = models.ForeignKey(User, on_delete=models.CASCADE) I am working on a View, in which user could assign Persons to a Group. I want to store User who created the relation (Membership). Something like that: class GroupForm(forms.ModelForm): class Meta: model = Group fields = ["members"] widgets = {"members": forms.CheckboxSelectMultiple} class GroupView(UpdateView): form_class = GroupForm model = Group def form_valid(self, form): for member in form.cleaned_data["members"]: member.user = self.request.user member.save() return super().form_valid(form) However, I'm getting error: django.db.utils.IntegrityError: NOT NULL constraint failed: myapp_membership.created_by_id Of course, I could make created_by field nullable and set created_by later, but what is the correct way to solve this? -
Django channels create a async count down
I'm trying to code a website like Gartic.io. I am using django channels as backend django websocket. But I don't know how to do a 30 second countdown async. I need this countdown to control the duration of each drawing round. I have an async function as handle_turn(self,room). And it handles turns. It calls my timer function after some checks like 2 or more player, which raund is it... What I tried async def timer(self,room): try: print('1') # check if there is an event loop loop = asyncio.get_event_loop() loop.run_until_complete(self.handle_timer(room)) except RuntimeError as e: print('2') # create a new event loop if there is no event loop if str(e).startswith('There is no current event loop in thread'): print('3') loop = asyncio.new_event_loop() asyncio.set_event_loop(loop) asyncio.get_event_loop().run_until_complete(self.handle_timer(room)) else: raise async def handle_timer(self,room): while room.duration > 0: await asyncio.sleep(1) # wait for 1 second await self.drop_duration(room) # drop duration by -1 print('duration is ' + str(room.duration)) # print duration if room.duration == 0: # time is up for turn await self.reset_duration(room) # reset duration to 30 I got an error RuntimeError: This event loop is already running -

Django Multi-tenant postgresql and mongoDB
I implemented, PostgreSQL and MongoDB in a project. MongoDB was used to saved logs. It was working fine before adding multi-tenancy in the postgresql using django-tenants=3.5.0 I created another branch and removed the MongoDB from it. So just the Postgresql with multi-tenants. It was also working fine. But the issue arises when I merge the branch and integrate the both Databases (PostgreSQL + MongoDB). I got the following error on migrate. AttributeError: 'DatabaseWrapper' object has no attribute 'set_schema' On exploring, I found this issue is related to database engine, so it should be django_tenants.postgresql_backend for PostgreSQL in-case of Django-tenant. But I'm already using it. and for MongoDB the engine is djongo . I'm also using database routes DATABASE_ROUTERS = ['logs.routers.MongoRouter', 'django_tenants.routers.TenantSyncRouter', ] here's the custom mongodb router.py class MongoRouter: """ A router to control if database should use primary database or non-relational one.

Django code to check the state of prometheus target such that it checks the state when the metrics data is scraped for that target
The customer will click on process request button and the monitoringConfigurationMultipleVM API gets called, then for every successful exporter configuration, one new job for that vm and exporter combo gets added in prometheus.yml file, and then that job we are passing as a paramater to the checkprometheusTargetStatus fucntion to check the state of the target of that job that has been recently added to prometheus.yml file(in our case every job will have only one target). We are trying to check the prometheus target state after the target is being added in the prometheus.yml file which has a scrape interval of 5s, but if we try to check the state of the target right after the target is being added to the prometheus.yml file, then we get the "target does not exist or has no data" case. And if we introduce a delay i.e. by adding time.sleep(some sec time), then if the time duration of sleeping is less than the combined scrape interval time of all jobs recently added to prometheus, then it gives "target does not exist or has no data" as a result for first target and for rest of the targets it gives correct state i.e. either "up" … -

How to assert FK is not null using it's id with mypy
I have a couple models: class MyUser(models.Model): district = models.ForeignKey( District, on_delete=models.CASCADE, default=None, blank=True, null=True, ) class District(models.Model): timezone = TimeZoneField(default="US/Eastern") And I'm trying to write a function that will get the timezone for a user. I tried this: def get_timezone_for_user(user: MyUser) -> datetime.timezone: if not user.district_id: return DEFAULT_TIMEZONE return user.district.timezone But mypy doesn't like this because it thinks user.district can still be None, even though I know it cannot because the existence of district_id means that user.district is also not None. I can add an assert user.district is not None in there, but then I will incur an extra query just to persuade mypy. Any ideas that don't involve adding an additional query? -

Django PlanetScale CA Cert Path
I have deployed a Django webapp on Vercel which uses a PlanetScale database. I have stored the PlanetScale connection strings as environment variables in Vercel. Django seems to be able to see the env variables; however, I am getting a FileNotFoundError for the CA cert path which was provided by PlanetScale. This is causing a server error that takes the app completely offline. This CA path was working previously when stored in a .env file. I have since attempted to replace the .env file and that no longer works either. Nothing else has changed in the project so I am at a loss as how to get this connection established again. Any help would be greatly appreciated.

Unable to import views from an app in Django
I am trying to import views from my app "first_app", the command from first_app import views doesn't work in Pycharm. What am I doing wrong? I also have tried: from first_project.first_app import views, but I get "ModuleNotFoundError" exception.
