How to handle mysql inactivity error in thread

How to optimize nested loop query of models with one-to-many relationship
I have two models with a one-to-many relationship. There are several objects of each model class in the database. I created a custom queryset that iterates over all parent objects and all child objects then loads them into a dictionary that is then used as the queryset. My question is how can I optimize my nested_query_loop function to hit the database less times? I tried incorporating select_related() and prefetch_related() but could never get it to work since I need to query it as a backward relationship in order to get each child object to be with its parent object. Second part of the question: I tried making the function reusable by creating parent_object and child_object arguments, but this did not work due to the fact that I have to use the ObjectName_set() method, which requires the objects name to be lower cased. Also the fact that ObjectName_set() has an underscore made it so child_object_set() and even ChildObject_set() was not recognized and threw an error. In my case the child objects model name is first letter upper case. So my question is: is there any way to manipulate the models name inside the function to be all lower cased? or is … -

template expectations when two models within same Django model file
I have two different (related) model classes within a Django tennis ladder app: Ladder and Player. For the corresponding views file, I include both sets of corresponding class-based views within the same file. And I also include all the urls in the same file as well. These look as follows: from django.urls import path from .views import HomePageView, PlayerListView, PlayerDetailView, \ PlayerEditView, PlayerCreateView, PlayerDeleteView, \ LadderListView, LadderDetailView, LadderDeleteView urlpatterns = [ path('', HomePageView.as_view(), name='home'), path('players/', PlayerListView.as_view(), name='players'), path('player/detail/<int:pk>/', PlayerDetailView.as_view(), name='player_detail'), path('player/edit/<int:pk>/', PlayerEditView.as_view(), name='player_edit'), path('player/create/', PlayerCreateView.as_view(), name='player_create'), path('player/delete/<int:pk>/', PlayerDeleteView.as_view(), name='player_delete'), path('ladder_history/', LadderListView.as_view(), name = 'ladder_history'), path('ladder/detail/<int:pk>/', LadderDetailView.as_view(), name = 'ladder_detail'), path('ladder/delete/<int:pk>/', LadderDeleteView.as_view(), name='ladder_delete'), ] Within the project urls I include the path to this urls file as follows. from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', include('django.contrib.auth.urls')), path('', include('players.urls')), path('', include('matches.urls')), path('accounts/', include('accounts.urls')), ] Here's the problem.

Waiting for request django
I need to send a request from my React client to the Django server. Processing this request may take about 30 seconds, due to the calculations in the function. What is the best approach to handle this case? Currently, I opt for celery+redis or WebSockets, but maybe there is a simpler approach? -
Why CORS error is rising only for search endpoint?
I have an app running on Django, React, and Elasticsearch. The react app is able to communicate with the django rest API normally in the endpoint http://localhost:8000/api/results/. But this endpoint renders the entire database. I use ES to create an endpoint that receives a query. The endpoint http://localhost:8000/api/results/q=query works correctly in the browser. However, when I tried to render it in the frontend, it returned a CORS error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8000/api/results/q=education. (Reason: CORS request did not succeed). Status code: (null). For development purposes, I allow CORS access to all addresses in my settings.py file: CORS_ORIGIN_ALLOW_ALL = True How is it possible to access http://localhost:8000/api/results/ from react and not access http://localhost:8000/api/results/q=query? P.S.:For completeness, here is my react code: export default function Body() { const location = useLocation(); const searchQuery = new URLSearchParams(location.search).get("q"); const [offices, setOffices] = useState([]); const office = true; useEffect(function () { async function fetchData() { const baseUrl = import.meta.env.VITE_API_URL; let apiUrl = `${baseUrl}/results/`; if (searchQuery) { apiUrl += `q=${encodeURIComponent(searchQuery)}`; } console.log(apiUrl); const res = await fetch(apiUrl); const data = await res.json(); setOffices(data); } fetchData(); }, [searchQuery]); -

DJANGO REST API - How do I restrict user access to API?
So I’ve been putting together a REST API using William Vincent’s REST API’s with Django book. I have everything up and going according to the book but I’m a bit of a noob so I need some clarification from the pros. How can I restrict a user without a token from seeing certain information within my API? Created user with Token: i added authentication_classes = [TokenAuthentication] to class UserList thinking if a user is logged in with a token that logged in user would be able to access that information of my api but I get the below: When I remove authentication_classes = [TokenAuthentication], I get the below. All users are able to see my API and I don’t want that, I only want users with a Token to view my api. Any help is gladly appreciated! Thanks! Code below # api/views.py from django.contrib.auth import get_user_model from rest_framework import generics, permissions from rest_framework.authentication import TokenAuthentication from .serializers import UserSerializer # Display List View - User class UserList(generics.ListAPIView): queryset = get_user_model().objects.all() serializer_class = UserSerializer permission_classes = (permissions.IsAuthenticated,) authentication_classes = [TokenAuthentication] # api/serializers.py from django.contrib.auth import get_user_model from rest_framework import serializers class UserSerializer(serializers.ModelSerializer): class Meta: model = get_user_model() fields =('id', 'username', 'email',) … -

How to make Django respect locale when accessing localflavor?
I'm trying to apply multi-language support to a Django application, and I have the basic configuration working so I can set a language session key and automatically pull the correct translations for the each gettext call around all my field labels. However, I have some Ajax calls that populate fields for country/state/province names, pulling data from the django-localflavor package, which includes full translation support. However, when I return, say, localflavor.jp.jp_prefectures.JP_PREFECTURES in my JSON response, even though my language session key is set to Japanese, and the values in that dictionary are wrapped with gettext, the values returned are in English, not Japanese. My Ajax view looks something like: from localflavor.jp.jp_prefectures import JP_PREFECTURES def get_country_states(request): lang = request.session.get('l', 'en') code = request.GET.get('code') if code == 'jp': states = {k: str(v) for k, v in JP_PREFECTURES} elif code == ... handle other cases return HttpResponse(json.dumps({'states': states})) How do I ensure str(v) renders the correct translated value based on the current language l session setting? I thought this happened automatically? Even though the values in JP_PREFECTURES are gettext instances, if I try and return them directly in the JSON response, I get the error: Object of type __proxy__ is not JSON serializable -
Django left join with filtered relation in QuerySet for ListView
I am a Django/Python novice. I am developing a website to help me manage a small golf society. A major function of the website is to enable members to view and book their place on upcoming events.

Django All-Auth with Djongo (PyMongo)
I've created a Django project that uses the Djongo plugin to connect to a MongoDB instance. All works well with Djongo, however, now that I am trying to implement all-auth, there are some problems. Upon logging in (using the default all-auth process and clicking Google), I get this DatabaseError. It doesn't really give any exception, but my theory is that I need to create a User model that uses the Djongo model, which I've been unsuccessful in doing. Has anybody done a similar setup that can help? Run this branch here (directions in README.md, however you will need a google OAUTH credential) to replicate the problem https://github.com/bens-schreiber/pushapp-2023/tree/schreiber/all-auth/backend -
I can't prepare multiple databases in Django (sqlite3)
There is a problem which I can't understand how that happens. First let me clear what do I want: Use a database called sol_data.sqlite3 for two models: SolModel1, SolModel2 (These models defined in an app called sol_app) Use a database called db.sqlite3 for any other models like always (Django built-in models and other apps) It's obvious db.sqlite3 should not include SolModel1 and 2. and sol_data.sqlite3 should only include SolModel1 and 2 tables. But when I migrate, both tables have all django models, and sol_data.sqlite3 have SolModel1 and 2 addition to them. I'm confused.

Filtering in the dictionary list for the jsonfield in Django
I have a django model that uses postgres json column. class ClassName(models.Model): data=JsonField(default=dict,blank=True,null=True,) This is the schema in the json field. { "name": "foo", "thing":[ { "id": "1", "key": "hello" }, { "id": "2", "key": "world" } ] } Is it possible to search against one key value in the list of dictionaries using ILIKE (icontains) operator?

I will be glad of any considerations ClassName.objects.filter(data__thing__contains=[{'key':'world'}]) - works (but only contains) ClassName.objects.filter(data__thing__1__key__icontains='wo') - works (but only with the indication of the element) -
