Problems trying to improve performance on ModelResource
We have a model, with almost 200k objects and an Export button on Admin that was getting timeout. The resource was dehydrating properties and accessing to DB many times, so I thought that create annotations to those known fields should fix I tried to override the get_queryset on my class that extends from resources.ModelResouce but without success, this override never had been called, I tried next to override the admin.ModelAdmin.get_queryset and then I had some changes and the export was way better than before, but the load on this Admin became to be too slow What is the better way to keep Admin on same performance and apply the annotations only on Resource class? -
TypeError: reverse() takes exactly 2 arguments (1 given)
For some weird reason, reverse function is not working even though my url has no arguments. Url.py: from django.urls import path from . import views urlpatterns = [ path("api/v2/app/nextdialog", views.NextDialog.as_view(), name="app-next-dialog"), ] views.py: class StartAssessment(generics.GenericAPIView): def post(self, request, *args, **kwargs): data = request.data request = build_rp_request(data) response = post_to_app_start_assessment(request) path = get_path(response) step = get_step(response) data["path"] = path data["step"] = step request = build_rp_request(data) app_response = post_to_app(request, path) message = format_message(app_response) return Response(message, status=status.HTTP_200_OK) functions.py: def get_endpoint(payload): head = { "Content-Type": "application/json", } url = reverse("app-next-dialog") response = requests.post(url, data=json.dumps(payload), headers=head) return response When I run this I get the following error. url = reverse("app-next-dialog") TypeError: reverse() takes exactly 2 arguments (1 given) Please does anyone have an idea what's wrong here. I wouldn't think I need to add any other arguments. Thanks -
Django & HTMX - after GET show only section of html template
I want to create an instagram clon. I created a post.html which includes a post-card.html file for all posts and a post-filter.html to filter the posts. <!-- simple post.html view --> <div> <div> {% include '_includes/bars/post-filter.html' %} </div> <div id="more-posts-wrapper"> {% for post in posts %} {% include '_includes/cards/post-card.html' %} {% endfor %} </div> </div> Now I added htmx to load more posts after clicking load more button. I tried to load the new posts after the existing one inside the div with id=more-posts-wrapper: <div> <div> {% include '_includes/bars/post-filter.html' %} </div> <div hx-get="?page={{ page_obj.next_page_number }}" hx-trigger="click" hx-swap="innerHTML" hx-target="#more-posts-wrapper"> <p>LOAD MORE</p> </div> <div id="more-posts-wrapper"> {% for post in posts %} {% include '_includes/cards/post-card.html' %} {% endfor %} </div> </div> Unfortunately, if I press the button, the correct reponse post gets delivered but the whole post.html document gets loaded after the div with id=more-posts-wrapper. I only want to load the post-card.html file and not reload the post-filter.html file. Does anyone know what I can do? -
My sheduled emails(django_q) not working on heroku
I want to mention that everything runs perfectly on my machine localy: I run py manage.py runserver with py manage.py qcluster and then I'm creating task with a deadline and getting an email at certain time, when my task is approaching the deadline, but it is not working on heroku. The problem is certainly not in smtp settings, because I'm getting regular mails through my app I'm using django_q library and sqlite3 as my db. I never deployed any apps before, so I was expecting issues, but I can't find any soution that works for me. I've just started to learn about async tasks, so I would also appreciate any good book/guide/etc. that can clarify how to work with schedulers and deploy all this stuff.

Django QuerySet Regex with MongoDB
I am trying to use Django QuerySet/Filter with Regular Expression to filter the records in my MongoDB database. For the Python packages, I'm using: Django 4.0.3 djongo 1.3.6 pymongo 3.12.6 Here's my current attempt (code): import re from .models import User regex = re.compile(pattern) result = User.objects.filter(name__iregex=regex.pattern) However, I get djongo.exceptions.SQLDecodeError every time I use the filter like above. After looking through StackOverflow, I find out that I can filter by using Django raw but I still want to know if there are any other ways to make the above codes viable. -

It is worth mentioning that this same code and configuration worked in the homolog version of the system. -

A Model is linked to two other models. How do I access the properties of that two other models in django

User model is defined in another file. I have not included that model code here. When a user books a room, the corresponding room object and user object is linked to the booking object. To display the bookings of the user, I need to query the Booking model using a User object. Here, my question is how i can access user and room object attributes inside the booking object? -

DRF and Knox Authentication: Demo accounts where user doesn't have to input credentials
I'm making an app with React as the front end and am handling authentication with knox. Everything is working fine but I require the ability for users to login to premade demo accounts without inputting any credentials. I can't figure out how to do this with Knox on the backend and I can't have the login info stored in my javascript. Any ideas how to accomplish this? Knox: class LoginAPI(KnoxLoginView): authentication_classes = [BasicLikeAuthentication] def get_post_response_data(self, request, token, instance): user = request.user data = { 'expiry': self.format_expiry_datetime(instance.expiry), 'token': token, 'user': user.username, 'role': user.roles.assigned_role } return data Front end for regular login: const handleSubmit = (event) => { event.preventDefault(); const data = new FormData(event.currentTarget); const credentials = btoa(`${data.get('username')}:${data.get('password')}`); const requestOptions = { method: "POST", credentials: 'include', headers: { 'Accept': 'application/json, text/plain, */*', 'Content-Type': 'application/json', "Authorization": `Basic ${credentials}` }, body: JSON.stringify({}) } fetch('http://127.0.0.1:8000/api/login/', requestOptions) .then(response => { if (response.status === 401) { setFailedLogin(true) } return response.json() }) .then(data => { localStorage.setItem('token', data['token']) }) .then(fetchCurrentUser) .then(() => { localStorage.getItem('role') == "Admin" ? navigate("/manage") : navigate("/maindash") }) .catch(error => console.log(error)) }
