How can I say graphene that I just need to accept an object? class SendEvent(MutationMixin, relay.ClientIDMutation): class Input: event = graphene.String(required=True) payload = # any object -
Improve Django application logs to only display custom log from Logging settings
I am trying to improve the logging of my Django application to have it in a standardized way for querying it with Loki and for each log that I create, 3 log entries are recorded. For example, any request (sucess or failed) to this endpoint below will generate three log entries. views.py class ModelViewSet(models.ModelViewSet): def retrieve(self, request, *args, **kwargs): try: # do something logger.info(f"{request.path} {request.method} 200: user {request.user.id} - success!") return Response(serializer.data) except Exception as exc: logger.warning(f"{request.path} {request.method} {exc.status_code}: user {request.user.id} - {exc.detail}") return Response(exc.detail, status=exc.status_code) settings.py LOGGING = { 'version': 1, 'disable_existing_loggers': True, 'formatters': { 'timestamp': { 'format': '{asctime} {levelname} {message}', 'style': '{', }, }, 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'formatter': 'timestamp' }, }, 'loggers': { 'django': { 'handlers': ['console', ], 'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'), }, }, } Output in console 2022-06-02 10:26:09,714 WARNING /api/v1/<path/ GET 403: user 71 - You do not have permission to perform this action. 2022-06-02 10:26:09,814 WARNING Forbidden: /api/v1/<path/ 2022-06-02 10:26:09,815 WARNING "GET /api/v1/<path/ HTTP/1.1" 403 12495 Any suggestion on how to optimize and have only one entry, preferably my custom logging entry and get rid of the other two? This will also help reduce drastically the size of the logs stored. -
React and django cache issue
I have a react and django app which is being served behind nginx. The /admin route and /api routes both point to uwsgi. However when loading these routes the react app is served unless a hard refresh of the page is peformed. It seems like react is serving all routes instead of just the index. Is there a way to exclude routes in react so it will only display if the path is "/" or is there something in nginx/django config I can change to overcome this issue. This is a snippet from my nginx conf: location / { try_files $uri $uri/ =404; } location /api/ { uwsgi_pass uwsgi; include /etc/nginx/uwsgi_params; } location /admin/ { uwsgi_pass uwsgi; include /etc/nginx/uwsgi_params; } and my django urls config: urlpatterns = [ path('admin/', admin.site.urls), path('api/v1/', include(routers.urls)) ] Any ideas on how I could proceed would be appreciated -
Django development static 404 not found: new files only
Curious issue on Django development server. Static files which are in existing use work just fine. When I add new files (of any sort) I get 404 not found. settings.py DEBUG = True INSTALLED_APPS = [ 'django.contrib.staticfiles', ] STATIC_ROOT = os.path.join(BASE_DIR, '') STATIC_URL = '/static/' template <img src="{% static 'media/cypress.jpg' %}"/> <!-- old file works --> <img src="{% static 'media/butterfly.jpg' %}"/> <!-- new file returns 404 --> Jquery files which were in use are found, those which were sat in the same folder unused before aren't. I assume therefore it's an indexing issue of some sort. I've tried python manage.py collectstatic but no joy. Any guidance much appreciated. -
I need to redirect users to a previously typed link after authentication. (I am using Django)
In my App, being authenticated is a must to access the content. Let's say someone shared a link such as http://website.com/form/ioxPwhRtV8zeW2Lj9njZjs4065Ml6u/viewform. If not authenticated, it redirects the user to the main login page. I need to figure out how once authenticated I redirect the same user back to the previously typed link http://website.com/form/ioxPwhRtV8zeW2Lj9njZjs4065Ml6u/viewform. I am using Django version 4.4 for my app. For a reference, here is my code: def login_view(request): """ Display the login form and handle the login action. """ form = LoginForm(request.POST or None) msg = None if request.method == "POST": if form.is_valid(): username = form.cleaned_data.get("username") password = form.cleaned_data.get("password") user = authenticate(username=username, password=password) if user is not None: login(request, user) now = datetime.datetime.now() current_time = now.strftime("%I:%M %p, %B %d") msg = f'Success - Logged in at {current_time}' messages.success(request, msg) # Look over here.

I want it to redirect any authenticated user to the previously typed URL. return redirect("/") else: msg = 'Invalid credentials' messages.error(request, 'Error validating the form') else: msg = 'Error validating the form' messages.error(request, 'Error validating the form') return render(request, "accounts/login.html", {"form": form, "msg": msg}) Mates, I need help fast. -
django models hierarchy question: related attributes of a ManyToManyField
As a fresh coder, I seriously have problems to build my models relations. Please check these two cases, How can I set current_reading_pages on my Scenario2? from django.db import models # Scenario1: Users can record their reading progress of a book. class Book(models.Model): name = models.CharField(max_length=128) class User(models.Model): current_reading_book = models.ForeignKey('Book', on_delete=models.CASCADE) current_reading_page = models.IntegerField() Result1: No problems about database, but Users can records their progress of only one book. Other scenario, which I want to build: from django.db import models # Scenario2: Users can record their reading progress of multiple books. class Book(models.Model): name = models.CharField(max_length=128) class User(models.Model): current_reading_books = models.ManyToManyField('Book') # current_reading_pages = ??? I want to save all progress of current books, for example, User A is reading 3 books, book1 till page 100, book2 till page 10, book3 till page 0. -

Django model inheritance with proxy classes
I've got proxy classes which have been created mainly to implement custom filtering, but there are some other fairly small custom methods as well, and they will be expanded to provide other custom logic as well. So say I have models: class Videos(models.Model): title = models.CharField(max_length=200) publisher = models.Charfield(max_length=100) release_date = models.DateField() class Superheroes(Videos): objects = SuperheroesManager() class Meta: proxy = True class Recent(Videos): objects = RecentManager() class Meta: proxy = True and model managers: class SuperheroesManager(): def get_queryset(self): return super().get_queryset().filter(publisher__in=['Marvel','DC']) class RecentManager(): def get_queryset(self): return super().get_queryset().filter(release_date__gte='2020-01-01') On the front end a user may pick a category which corresponds to one of the proxy classes. What would be the best way to maintain a mapping between the category which is passed to the view and the associated proxy class? Currently I have an implicit dependency whereby the category name supplied by the front end must be the same as the proxy class name, allowing for a standard interface in the view: def index(request, report_picked) category = getattr(sys.modules[__name__], report_picked) videos = category.objects.all() I'd like to move away from this implicit dependency, but not sure what the best way would be. I wouldn't want to maintain a dictionary and can't use a … -
How to get Id from CreateView in django

Why do my javascript integration in a django template does not work?
I am really new to django and i am trying to build a small page where a chart with chart.js is shown. I want to load the javascript file static. I created a basic html-file called data_table.html and added a folder static where three files are in: data_table.js, styles.css and a picture bild.jpg. The html file is: {% load static %} <!DOCTYPE html> <head> <link rel="stylesheet" href="{% static 'styles.css' %}" type="text/css"> <script type="text/javascript" src="{% static 'data_table.js' %}"></script> <title>Data viewer</title> </head> <body> <canvas id="myChart" width="200" height="200"></canvas> <script> </script> <p class="text">Picture:</p> <br> <img class="img" src="{% static 'bild.jpg' %}" alt="My image"> </body> </html> The css file and the picture are loaded. The picture is displayed and with the css file i can resize the picture. So that works i guess? The javascripts file looks as follows: const ctx = document.getElementById('myChart').getContext('2d'); const myChart = new Chart(ctx, { type: 'line', data: { labels: [{% for d in data%}'{{d.label}}',{%endfor%}], datasets: [{ label: '# of Votes', data: [{% for d in data%}{{d.data}},{%endfor%}], backgroundColor: [ 'rgba(255, 99, 132, 0.2)', 'rgba(54, 162, 235, 0.2)', 'rgba(255, 206, 86, 0.2)', 'rgba(75, 192, 192, 0.2)', 'rgba(153, 102, 255, 0.2)', 'rgba(255, 159, 64, 0.2)' ], borderColor: [ 'rgba(255, 99, 132, 1)', 'rgba(54, 162, … -
Django export model to csv for ManyToManyField
Have a few tables for which I successfully built export to CSV, based on the Models. However, for one where I count the 'likes' for the news (posts) I'm getting nowhere. Here is my model: class News(models.Model): news_title = models.CharField(max_length=300) news_text = models.TextField(max_length=2000) news_author = models.CharField(max_length=150) news_date = models.DateField(default=now) likes = models.ManyToManyField(User, related_name='user_like', blank=True) @property def total_likes(self): return self.likes.count() Problem is, that I can print out to CSV all items from the model, but if I print "likes" I get duplicated (or more) rows in CSV. The reason is, that if News is liked by 3 users, I get 3x rows on CSV for each User and under "Like Count" column I get their IDs. What I would like to get instead is: 1x row per News with a total of likes for each news. and view.py @login_required def export_news(request): newss = News.objects.all() response = HttpResponse(content_type='txt/csv') writer = csv.writer(response) writer.writerow(["ID","Title","Author","Date","Text","Likes Count"]) for news in newss.values_list('id','news_title','news_author','news_date','news_text','likes'): writer.writerow(news) response['Content-Disposition'] = 'attachment; filename="News_list.csv"' return response Appreciate any help.

How to optimize loading millions of records in MongoDB with Django admin?
I have MongoDB with over 20 million records integrated with Django administration. Both services are running in k8s. I have already applied some of the optimisations below: Adding NoCountPaginator (disable counting) Indexing MongoDB Sorting queryset Also, I read about adding skip and limit is not recommended since it will make the performance even worse. But still, loading is extremely slow and frequently throws timeout errors. Here's the custom manager to get queryset: models.py class RuleDataManagerRemoved(DjongoManager): def get_queryset(self): event_horizon = datetime.datetime.now() - datetime.timedelta(days=180) return RuleDataQuerySet(model=self.model, using=self._db, hints=self._hints).filter(last_change__gte=event_horizon) The filtering happens with indexed field, so I think the impact is not critical here. admin.py @admin.register(models.ChangedProductSlugs) class ChangedProductSlugsAdmin(RuleDataAdmin): paginator = NoCountPaginator show_full_result_count = False list_display = ('old_category_slug', 'old_product_slug', 'new_category_slug', 'new_product_slug', 'tld', 'last_change', 'created_by', 'stav') list_filter = ('last_change', ('old_product_slug', SingleTextInputFilterOldProduct), ('old_category_slug', SingleTextInputFilterOldCategory), ('new_product_slug', SingleTextInputFilterNewProduct), ('new_category_slug', SingleTextInputFilterNewCategory), 'deleted', 'deleted_by', 'tld') search_fields = ('old_category_slug', 'old_product_slug', 'new_category_slug', 'new_product_slug') resource_class = resources.ChangedProductSlugsResource actions = ['restore_queryset'] def stav(self, obj): return not obj.deleted stav.boolean = True def changelist_view(self, request, extra_context=None): default_filter = False try: ref = request.META['HTTP_REFERER'] pinfo = request.META['PATH_INFO'] qstr = ref.split(pinfo) if len(qstr) < 2: default_filter = True except: default_filter = True if default_filter: q = request.GET.copy() q['deleted__exact'] = '0' request.GET = q request.META['QUERY_STRING'] = request.GET.urlencode() return super(ChangedProductSlugsAdmin, … -
