requests.exceptions ConnectionError Connection aborted.', ConnectionResetError(104, 'Connection reset by peer')
We have implemented a program to broadcast the commentary of sports, which will take data from firebase when firebase is triggered by data and send data to telegram channel. Everything has been good for so long. But recently we have been facing this connection reset issue? Can anyone please help? I have already tried to use time.sleep() function. But still there is issue. This problem exactly happens after running commentary for some time. It works well for sometime and then comes this error. Note: During commentary we may send 4/5 request per second.

Adapt global PAGE_SIZE setting in Django REST Framework's browsable API to a different local PAGE_SIZE setting
We are using the Django REST Framework with pagination and a browsable API. The global parameter for the page size in settings.py is set to 10000 in order to get higher performance when accessing the API via HTTP requests which works well: REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": [ "rest_framework.authentication.SessionAuthentication", "rest_framework.authentication.TokenAuthentication", ], "DEFAULT_FILTER_BACKENDS": ["django_filters.rest_framework.DjangoFilterBackend"], "DEFAULT_PAGINATION_CLASS": "rest_framework.pagination.PageNumberPagination", "PAGE_SIZE": 10000, } Now the problem is that this is directly linked to the browsable API which also lists 10000 entries per page. This of course takes very long or even breaks within certain browsers. Is there a way to change this behaviour locally for the browsable API? Thanks in advance! -
Writing to Firestore with Firebase Admin SDK causes app to freeze
I am trying to use Firebase Admin SDK in a Django app using a service account. I followed the instructions as per the official documentation. However, the app gets stuck at the point when Firebase Admin is attempting OAuth2 using Google APIs. My code is as follows: import firebase_admin from firebase_admin import credentials from firebase_admin import firestore cred = credentials.Certificate(key_path)# path to serviceAccountKey firebase_admin.initialize_app(cred) db = firestore.client() doc_ref = db.collection(u'users').document(u'alovelace') # The following causes the app to freeze doc_ref.set({ u'first': u'Ada', u'last': u'Lovelace', u'born': 1815 }) The last message displayed in logs is: 2022-07-06 06:23:38,519 DEBUG Making request: POST https://oauth2.googleapis.com/token The app freezes after that message with no additional info. Any ideas why is this happening? -

Django import-export error reporting for rows
I am using Django Import export for creating a data upload endpoint. However, in case there is an error while uploading the data, I want to know which row numbers have an issue and what the issue is. If there is an error on line 50 and line 60, then it should tell me that both lines 50 and 60 have errors. Currently, if I use raise_errors method then it only shows the error on line 50 and then stops checking. I can do a line-by-line iteration but that method is considerably slow. How can I achieve this? -

Why is my table not filtering? django-filters
So yeah, it isn´t filtering. I enter the search and the table doesn't filter. I have checked my code numerous times and it just ain't working. I need someone else's feedback because I'll go crazy. It probably is a very stupid mistake but you know how these things go. So, I've got my: #filters.py import django_filters from .models import * class ContratosFilter(django_filters.FilterSet): class Meta: model = Contratos fields = ['id', 'name', 'contractor', 'contractee'] #views.py def contratostabla(request): contract=Contratos.objects.all() paginator = Paginator(contract, 12) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) myFilter= ContratosFilter(request.GET, queryset=Contratos.objects.all()) return render(request, 'contracts.html', {'contract':contract, 'myFilter':myFilter, 'page_obj':page_obj}) #contracts.html <form method="get"> {{myFilter.form}} <button class="btn btn-primary btn-sm" type="submit">Search</button> </form> My view also includes paginator and the table as you can see. The terminal says GET /contracts/?id=3&name=&contractor=&contractee=& . I would guess it is not posting it. I have no idea what is stopping it from working. -

When attempting to click on an entry to see the detail view which displays the fieldpanels, I have about 5-10 seconds of loading which tells me massive amounts of queries are being made. Is there any way to use select_related() on a fieldpanel field? In this particular case I'd like to use select_related on "day" @register_snippet class EventSnippet(index.Indexed, Event): panels = [ FieldPanel('name'), FieldPanel('day'), ] search_fields = [ index.SearchField('name', partial_match=True), index.RelatedFields('day', [index.SearchField('calendar_year')]), ] class Meta: proxy = True -
How do you add one object to a Django Model that has a ManyToManyField?
I am trying to create a social media type site that will allow a user to follow and unfollow another user. followers has a ManyToManyField because a user can have many followers. models.py class Follower(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, default="") followers = models.ManyToManyField(User, related_name="followers") views.py def username(request, user): #get user user = get_object_or_404(User.objects, username=user) posts = Post.objects.filter(user=user).order_by('-date_and_time') #follow button code follow_or_unfollow = '' try: following = get_object_or_404(Follower, Q( user=user) & Q(followers=request.user)) print(following) except: following = False if following: follow_or_unfollow = True else: follow_or_unfollow = False if request.POST.get('follow'): follower = Follower.objects.create(user=request.user) follower.followers.add(*user) follow_or_unfollow = False elif request.POST.get('unfollow'): follow_or_unfollow = True #following.delete() When it gets the 'follow' POST request, I want it to add the user who sent it (the one that is logged in) to be added to the followers. Right now, I am getting this error when I try to do that. TypeError: django.db.models.fields.related_descriptors.create_forward_many_to_many_manager.<locals>.ManyRelatedManager.add() argument after * must be an iterable, not User I know it says that it has to be iterable, but is there any way to just add one object at a time. Also, how would you delete this particular object?
